  • Today we performed a repeat MRI of the spinal cord in a dog that had come to us a month ago or so for extreme cervical pain and neurologic deficits with knuckling on the paws and collapse.
    At MRI we diagnosed a tumor, most likely a meningioma, encircling and compressing the spinal cord in the upper spine just behind the head... the tumor was very large and compressive and in a difficult location so that surgery was not a reasonable option. The owners opted for radiation therapy which consists in irradiating the tumor with radiation to kill as many tumor cells as possible.
    Only a few days after the first treatment, the pain was relieved and locomotion back to normal. We repeated the MRI today and the images here show the pre and post treatment images; the tumor is in white (T) encircling the spinal cord (c) which has a dark grey color. One can appreciate the reduction in size of the tumor; there is now room for normal spinal fluid (arrow, in black) around the cord whereas on the pre-treatment scan a few weeks ago there was no spinal fluid at all around the cord at that level because of the space occupied by the tumor.
    Our expert colleagues in radiation oncology (https://www.facebook.com/radiation.oncology.9?fref=ts) did a great job in helping relieve the pain and improving quality of life, giving these owners a chance to spend more quality time with their favorite pet... GREAT JOB!!! :-D

  • Three papers featuring PENN VET RADIOLOGY staff were just published online in the 'Early View' section of three Veterinary Sciences journals. Clinical research to improve medical and surgical care of our pet patients is a very important part of what we do here, in addition to education and clinical care in our hospitals.
    The first in Veterinary Radiology and Ultrasound by our 3rd year resident Dr Joey AMORY, described the computed tomography characteristics of tumors of dental origin in dogs. CT is often used as a pre-operative tool to assess extent of oral masses in dogs and is very important in surgical and radiation therapy planning and this serves as a guide to the recognition and classification of these tumors using this imaging modality.
    The second by our former resident Dr Guillem-Gallach was published in the Journal of the American Animal Hospital Association, and reports on the use of Magnetic Resonance Imaging (CT) in the assessment of a dog with fluid accumulated around the heart in the pericardial sac (pericardial effusion). A common cause for this life-threatening condition is tumors at the base of the heart and recognition of presence or absence of a tumor is key in differentiating dogs that would benefit from surgical removal of the pericardial sac vs these that would not; in this particular case, MRI was instrumental in confirming that there was no mass at the heart base, where as on echocardiography (ultrasound of the heart) the cardiologists had suspected a mass. MRI is rarely used in veterinary medicine in the assessment and management of cardiac condition however there are specific application where it could be very useful and of great benefit in diagnosis and management of our patients. Very few places can perform cardiac gated MRI in dogs, and PENN VET RADIOLOGY is one of them.
    The third paper by PENN VET surgeons (published in Veterinary Surgery) was set up to assess the consequences of pelvic symphysiotomy on the sacro-iliac joint. This surgery is performed when there is a need to access the pelvic canal to for example remove tumors around the rectum, some prostatic diseases, colon diseases etc. However a common complication of this procedure is potential dislocation of the sacroiliac joints, which is where the spine attaches to the pelvis. The aim of the study was to exactly quantify the degree of retraction of the pubis that can be safely applied when splitting the pelvis open without causing sacroiliac dislocation. This information will be very useful for surgeon carrying on this procedure.

  • GREAT DAY!!! After our two graduating residents successfully passing their ACVR certifying examination and becoming board-certified radiologists last months (Drs Ryan and Castro), our two 3rd year residents (Drs Matt PAEK and Joey AMORY) just got notified that they both successfully passed the qualifying ACVR written (theoretical) examination!!

  • One of our third year residents, Dr Paek, just got his paper published in the September issue of Veterinary Radiology and Ultrasound. He describes the prevalence and origin of a radiolucency that is commonly seen on lateral radiographs of the stifle (knee joint) in dogs. AWESOME JOB Dr PAEK!!!!! Very proud of you!!! :-D

  • Another awesome case at PENN VET RADIOLOGY yesterday. A young German Shepherd was presented with a history of chronic regurgitations; the radiographs taken at the referring veterinarian (top left) showed a very dilated esophagus (red arrows) cranial to the heart, causing marked ventral deviation of the trachea (yellow arrows). Caudal to the heart base the esophagus decreased abruptly in size; these features are very characteristic of a condition called 'vascular ring anomaly', a group of congenital abnormalities that are due to abnormal development of the vessels at the heart base which can sometimes cause constriction of the esophagus at the level of the heart leading to progressive dilation cranial to the heart with formation of a large pouch; the animal regurgitates food that cannot pass through the area of stricture. Complications include weight loss, pneumonia due to aspiration of food and ultimately death if the condition is not corrected surgically. On the VD radiograph the trachea showed a focal kink to the left at the heart base which is very characteristic of a condition called 'Persistent of the right aortic arch' whereby the aorta forms on the right side of the heart base as opposed to the left; the esophagus becomes constricted by the ligamentus arteriosus, the aorta and the pulmonary artery. The surgeons consulted with Dr Buchanan, a pioneer cardiologist from PENN VET, now professor emeritus who has done extensive portions of the early works in veterinary cardiology including congenital vascular anomalies such as these (http://cal.vet.upenn.edu/projects/cardiosf/project/praapres/praa.htm). He was concerned there could be another anomaly in this dog due to the unusual severe ventral deviation of the trachea. For this reason the surgeons decided to ask PENN VET RADIOLOGY to perform a CT angiography (top right) to get a thorough assessment of the association of vascular anomalies and plan for the best treatment method, either surgical (opening the thorax up) or minimally invasive surgery which can be done by our colleagues at https://www.facebook.com/pages/Penn-Vet-Minimally-Invasive-Surgery-Diagnostic-Group/352189304877861 ...

    The CT angiography showed that the aorta was originating from the right rather than the left side (as you can see on the top right image, view of the heart from the left of the animal, the aorta arises form the heart in the background, i.e. on the right side); other abnormalities were present including a retro-esophageal left subclavian artery (pink arrow), a bi-carotid trunk (instead of a brachiocephalic trunk, green arrow) and an aberrant right subclavian artery (blue arrow) originating from the aorta rather than the brachiocephalic trunk). The latter two conditions do not need surgical corrections however the former two do.

    The images at the bottom are 3D reconstruction of the air filled space out of the CT data; on the left the lungs are in place on the right I removed them to leave only the trachea (yellow arrows) and esophagus (red arrows). The image in the middle is viewed form the ventral aspect and on the right from the right side. The severaly dilated, pouch-like esophagus is visible (red arrows) as well as the tracheal deviation (yellow arrows) and characteristic focal kink to the left (yellow arrowhead) seen with 'persistent right aortic arch'. The area of esophageal stricture (yellow star) is also visible. After the stricture, the esophagus shrinks down to a normal size.

    The patient was taken to surgery where the radiographic findings were confirmed and corrected. CT angiography is an excellent way to assess completely the anomalies present and helps the surgeon in preparing for the surgery so that anesthesia time is reduced as much as possible in these challenging patients.

  • Description of Service and Procedures

    Penn Vet, Ryan Hospital, radiologyMR imaging is used primarily for evaluation of the central nervous system (brain and spinal cord). Other regions of the body can be evaluated if clinically indicated. MRI provides high resolution, high contrast images. It is sensitive for detecting soft tissue pathology that may not be detectable by plain films or CT imaging.

    A GE 1.5 Tesla MRI scanner allows superb imaging of internal structures and provides soft tissue detail not available with conventional X-rays or CT scans.  MRI data is acquired by a certified MRI radiology technologist with training in both the human and veterinary fields. MRI images are interpreted by board-certified specialists in radiology and neurology.

    Pre-anesthesia evaluation is performed by a board-certified anesthesiologist who works in conjunction with the client and referring veterinarian to provide optimal patient care. The anesthesiologist will select the drugs and administration protocol according to each patient’s individual requirements. The ECG, blood pressure and respiratory indices are continuously monitored during the imaging session.

  • At least one veterinarian, numerous certified veterinary anesthesia technicians and a MRI technologist are always on site to provide care. Vital signs of every patient are monitored with the aid of specialized equipment throughout each procedure. A centralized preparation and recovery area allows for efficient and constant observation during anesthesia and recovery.

    Results are conveyed promptly to the referring veterinarian via a faxed report. The RITC is committed to providing the highest level of service to patients, clients and referring veterinarians. Our goal is to deliver a smooth, positive experience from the time your client enters our facility to the time you have your results.

The Section of Radiology members include two full-time faculty, three staff-veterinarians, five residents, one administrative assistant, one MRI technologist and five technologists.

FAQs for Pet Owners

Q: What is Radiology?

  • A: The branch of medicine known as radiology was born when German physicist Wilhelm Roentgen accidentally discovered x-rays while working in his lab in 1895. The x-ray's extraordinary benefit to medical science was immediately recognized and, with the research of French scientists Marie and Pierre Curie that followed Roentgen's discovery, scientific and technological advances have led to the important role radiology plays today in the diagnosis and treatment of disease.
    Radiology is both a diagnostic and therapeutic tool. Diagnostic imaging employs a number of different modalities, such as plain radiography, CT scanning, magnetic resonance imaging, ultrasound, and nuclear medicine, to identify disease and other conditions within the patient’s body. Therapeutic imaging, commonly called interventional radiology, is a subspecialty that involves the use of imaging technology to carry out minimally invasive procedures with the help of devices such as catheters, balloons, and stents to open blocked blood vessels, drain fluid, and perform needle biopsies.
    With the exception of ultrasound, imaging studies are typically performed by a trained technologist, while the veterinary radiologist, a specially trained veterinary doctor, reviews and interprets the radiographic images and reports the findings to the patient's primary doctor. Typically these reports are finalized within 2 to 12 hours after image acquisition.
    Today, the radiologic sciences are on the brink of a new age. Digital imaging and computerized data has enabled the effective and efficient delivery of diagnosis and treatment thereby improving patient care. The section of radiology at the veterinary school of the University of Pennsylvania is at the helm of these exciting advances in imaging technology. The work being done in our section of radiology will continue to benefit healthcare to our patients and around the world.

Q: What is a Veterinary Radiologist?

  • A: An ACVR Diplomate is also known as a Board Certified Veterinary Radiologist. At least 3 years of advanced training in an American College of Veterinary Radiology (ACVR) Accredited Radiology Residency Program is required to take the ACVR Radiology Board Certification Examination. Many Radiology Residency Programs are 4 years. All of our radiologists are board certified and experienced in all the imaging modalities available to your pets, including digital radiography, ultrasound, computed tomography and MRI.

  • A: Once the imaging study is completed, they will be reviewed by a radiologist within hours and a report generated. We can burn a CD with the digital images and send them over to your referring veterinarian. Images are stored on a remote server perfectly secured so that they will always be accessible within seconds when you bring your pet to our hospital again.

Q: Will my animal be sedated or anesthetized?

  • A: Many times sedation or general anesthesia will be necessary for imaging, because most techniques require your pet to be completely still for a few seconds / minutes. If such is the case, your primary doctor will contact you to request your authorization and the procedure will be performed under the supervision of experienced and trained anesthesia nurses and doctors.

Q: Will my pet have his hair clipped?

  • A: If your animal needs an ultrasound, the hair will have to be clipped because it would prevent good imaging and thereby prevents an accurate diagnosis to be made.

Q: What is a radiographic dye?

  • A: A dye is a chemical substance that is used to increase visibility of structures in particular vessels and tumors. If your animal requires injection of a radiographic dye (required most of the times during a CT or MRI, and sometimes for some radiographic procedures), the contrast dyes with the best safety profile will be used and your pet will be closely monitored.

Q: What kind of machine do you use and who will perform the study?

  • A: Our technologists and radiologists have extensive training and experience in veterinary diagnostic imaging.
    We use machines very similar to the ones used by your own doctor, but we adjusted doses and protocols to veterinary patients. We provide images services with a quality similar to what is provided in human medicine.

Q: I am bringing my pet for an out-patient imaging procedure, what should I expect?

  • A: The Rosenthal Imaging and Treatment Center offers outpatient ultrasound, CT, MRI services. You must be referred by your veterinarian for an appointment to be scheduled (see specific sections about ultrasound, CT and MRI services). On the day of the appointment, you will meet with a radiology technologist (ultrasound) or an anesthesia nurse (CT or MRI) and your pet will be directed to the appropriate service.
    • For ultrasound, the hair will be clipped on the belly, and the examination will be performed promptly by a board-certified radiologist. A report will be generated right after the scan and provided to you as well as a CD with the images obtained during the scan. If the clinical schedule allows it, the radiologist will come meet you and go over the findings.

    For CT and MRI your pet will be brought into the RITC facilities where highly trained veterinary anesthesia nurses and doctors will handle the anesthesia during the CT or MRI procedure. The images will be interpreted by a board-certified radiologist and the report faxed over to your veterinarian within a couple hours. When your pet has recovered from anesthesia you will be able to take him home. You should plan to have the entire day available to drop off your pet and pick him up. A CD with the images will be provided to your veterinarian.
