Three types of Fellowships are offered in Cross-Sectional Imaging:
- Body (Cross-Sectional) Imaging (2 positions):
- 3 four week blocks each of Body CT, US, Body MR; 1 block elective in other areas (including Mammography, Breast MRI, PET-CT, Chest and IR)
- MRI (2 positions):
- 10 four week blocks Body MR; 3 blocks of electives
- Cardiovascular Imaging (1 position)
- 6 four week blocks of Cardiovascular MR and CT
- 6 four week blocks of Body Imaging (Body MR, CT, US)
- 1 Block of elective
Elective time is flexible depending on service coverage requirements.
With a new hospital (Smilow Cancer Center) the clinical MRI service includes four 3.0T (Siemens Verio and Skyra) and three 1.5T (Siemens Avanto, Espree, and Aera) scanners within Yale-New Haven Hospital, one off-site 1.5T (GE HD) scanner in a nearby facility, and one 3T (Siemens Skyra) scanner at a separate off-site facility.
The Body MRI service typically reads between 20-30 cases per day and provides the perfect balance between clinical workload, teaching, and hands-on experience.
We do a high volume of Liver MRI for hepatoma screening, as well as transplant evaluations and monitoring of disease following loco-regional therapies such as TACE, RFA, and Y-90 ablation. Other busy clinical programs include MR enterography, imaging of the female pelvis, MRI abdomen/pelvis for cancer staging and surveillance, and MRI prostate for targeted biopsy and tumor surveillance.
Dedicated MR Fellows spend 9-10 four-week blocks in Body MRI and are responsible for running the clinical service with primary responsibility for protocols and initial interpretations. The goal of the fellowship is to provide fellows with the skills necessary to be the “go to” person for MRI issues in their future practices. In addition to clinical knowledge, relevant physics, MR safety, protocol design, and image optimization are included in the curriculum. Rotating Body Imaging Fellows, who spend 3-4 four-week blocks on the service, will also gain the skills necessary to interpret almost any Body MRI case they are likely to see in their future practices.
CT and PET/CT
The CT service presently utilizes six 64 slice scanners and one 16 slice scanner, as well as one 64 slice and one 16 slice PET/CT scanners. Another 64 slice scanner is present in a nearby facility. Fellows supervise and interpret all Body CT exams including CT colonography, CT angiograms, and living donor kidney and liver exams. They will learn and become proficient in performing advance 3D post-processing (Vital Images Vitrea). Radiation dose reduction tools include adaptive statistical interactive reconstruction and prospective cardiac gating.
The US service provides comprehensive training in all areas of ultrasound. Attendings and trainees are physically stationed in the inpatient/outpatient clinic where they provide direct support for 9 ultrasound rooms including checking scans and interacting with patients. Support is also provided for scans performed in the Emergency Department, Transplant Clinic, Vascular Lab and Thyroid Clinic, which are located within the hospital. Fellows have the opportunity to spend time in these clinics as well.
In addition to the standard fare (US of the right upper quadrant, kidneys, gynecology, early OB, carotid arteries, and leg veins), fellows will gain experience in performing more subspecialized exams, such as pre and post transplant renal and liver Doppler, thyroid/parathyroid US, hemodialysis access evaluations, upper/lower extremity arterial Doppler, transcranial and MSK ultrasound. The US rotation includes experience in image-guided biopsy FNA of thyroid nodules and lymph nodes, as well as paracentesis and thoracentesis.
The cardiovascular fellow is responsible for supervising and monitoring all cardiac MRI, cardiovascular MRA (thoracic and peripheral), and coronary CTA examinations; post processing the images on a dedicated cardiac imaging workstation; and generating reports. The fellow will also be responsible for interpreting aortic and certain lower extremity CTAs. Fellows have the opportunity to rotate through nuclear cardiology (SPECT and PET). Post processing software/hardware includes a GE ADW, Vital Images Vitrea, and CMR42 cardiac MR workstations. We perform between 500-600 Cardiac MRI / Thoracic MRA cases per year, including assessment of adult and pediatric congenital heart disease, evaluation of cardiomyopathy and arrhythmia (hypertrophic cardiomyopathy, ARVC, and atrial fibrillation), and evaluation for viability.
Partially paid service component is required in the Emergency Radiology Department. For the 2014-2015 year the requirement is as follows: To fulfill your call commitment, all fellows are expected to cover 12 weekend shifts per year on the Emergency/Teleradiology Service as an attending physician.
[Weekend shifts include Saturday and Sunday day (8:00AM - 5:00PM)]
Fellows are encouraged to, but are not required to, participate in clinical research projects. For those interested in basic research, there is an array of whole body and animal research magnets in a dedicated research MR facility in the Yale University School of Medicine. These include 10 research scanners (with 1.5T, 3T, 4T, and 7T human scanners and 4.7T, 9.4T, and 11.7T small bore animal scanners). There are active research programs in cardiovascular MRI, MR spectroscopy, oncologic imaging, radiation safety, image processing, and contrast agents.
There are bi-monthly departmental Interesting Case Conference, bi-weekly Fellows Lectures (which include didactic sessions on MR physics), and a weekly Body Club where fellows present challenging cases for discussion. Prominent guest speakers present Diagnostic Radiology Grand Rounds every other week from September to May. There are also a variety of interdisciplinary conferences (GI cancer, lymphoma, melanoma, liver tumor board, liver transplant, new GI cancer patient) that fellows can participate in, as well as many other interesting lectures at the medical school and on the Yale University campus.
Fellow Conference Schedule (2015-2016 academic year):
• Tuesday, 12 noon: Fellows Didactic Lecture
• Wednesday, 12 noon: Fellows Didactic Lecture
• Every 2nd Wed., 1pm: Interesting Case Conference
• Thursday 12:30pm: Grand Rounds (every other week Sept.-May)
• Thursday, 9:00am: Body Club
• Twice Monthly 1 hour didactic and hands on MSK US lecture series
Call responsibilities will be shared equitably amongst all Fellows.
While there is no in-house overnight call for fellows, an MRI beeper call is shared with the senior residents. The “on call” MRI fellow is responsible for interpreting emergency afterhours Body MRI exams (a laptop with PACS access is provided on a rotating basis). Over the past several years there have been, on average, two emergency cases per week. All cases are co-interpreted with staff in real time so fellows are not left alone in the middle of the night.
