Abdominal Imaging Fellowship

Program Director: Dr. Natasha Wehrli

Associate Program Director: Dr. Grace Lo


The Abdominal Imaging fellowship is a one year, non-ACGME accredited program that provides up to five radiologists per year with comprehensive training in abdominal and pelvic imaging, with an emphasis on multiparametric MRI. Our fellows receive broad clinical experiences in inpatient, emergency, and ambulatory care at NewYork-Presbyterian Hospital, a comprehensive, integrated academic healthcare system ranking in the top five hospitals nationally and ranking number one in New York in the U.S. New & World Report’s annual survey of “Best Hospitals”. Our state-of-the-art imaging equipment and facilities provide fellows with the opportunity to develop expertise in advanced and emerging techniques in US, CT, and MR imaging, with the option for additional training in PET-CT and PET-MRI.  Abdominal Imaging fellows are able to design an experience tailored to their individual interests and goals, and our graduates have taken a broad range of positions in private practice, academic medicine, research, and informatics.  

Positions Available and Important Dates:

  • 2024-2025: We will be offering 4-5 Abdominal Imaging training positions and up to 2 combined Cardiothoracic/Abdominal Imaging training positions. In accordance with the SCARD guidelines, applications will be accepted beginning November 1, 2023, and we will offer interviews beginning January 8, 2024. All interviews will be virtual via Zoom. Interested candidates should apply early in the season, as we review applications regularly and on a rolling basis.

Clinical Experience

The Abdominal Imaging fellowship is based at NewYork-Presbyterian Hospital/Weill Cornell Medicine.  With a large primary-care and tertiary-level referral base, the clinical service is comprised of a high-volume and full scope of abdominopelvic imaging. Fellows gain experience with cutting edge GE and Siemens technology including two PET/MRI scanners (Siemens Biograph mMR and GE Signa PET/MR); GE Advantage Workstations; and multiple software platforms including TeraRecon, Vital Vitrea, SyngoVIA, and DynaCAD. Our advanced 3D Imaging Data Evaluation and Analysis Lab (IDEAL) complements
the training experience with on-demand 3D reconstructions, volumes, tumor segmentation, custom MIPS, and image fusion.


Highlights of our practice include:

  • Hepatobiliary Imaging: Hepatocellular and cholangiocarcinoma screening utilizing US, CT, and MRI with both extracellular and hepatobiliary contrast agents; pre- and post-treatment evaluation (including transarterial chemoembolization, Y-90 radioembolization, thermal ablations) with LI-RADS and OPTN; pre- and post-transplant imaging; liver donor evaluation; MR elastography; state-of-the-art Liver Lab techniques for iron and fat quantification. 
  • Pancreaticobiliary Imaging: Solid and cystic pancreatic neoplasms; acute and chronic pancreatitis with secretin MRCP; primary sclerosing cholangitis; emergency pathologies including choledocholithiasis and acute cholecystitis.
  • Transplant Imaging: Pre-transplant CT and MR evaluation of liver, kidney, and pancreas transplant recipients and organ donors, including living donors for both kidney and liver transplants; MR, CT, and US follow-up of transplant recipients.
  • 3T Comprehensive Prostate Imaging: PI-RADS classification of over 1,500 prostate MR annually, with hands-on prostate segmentation for over 300 targeted fusion biopsies performed per year in conjunction with the IDEAL lab and Urology. 

    Abdominal Imaging

  • Genitourinary Imaging: Urinary tract and gynecologic cancers, including PET/MR evaluation; pre- and post-treatment imaging after uterine fibroid embolization; dual energy CT imaging of the urinary tract.

Fellows are granted one protected, full academic day per week to pursue research, education, or systems improvement projects with attending staff mentorship.

 Clinical and didactic sessions include:

  • Interesting Case Conference: Interesting Case Conference: Tuesdays at 11AM. Fellow-driven weekly, division-wide Abdominal Imaging conference attended by all Abdominal Imaging attendings, fellows, and residents on rotation. Interesting and challenging cases, as well as emerging techniques, artifacts, protocol issues, and QI/QA, are presented and discussed. Guest speakers are invited to present special topics, with past invited speakers including full-time faculty from the Cornell MRI Research Lab to discuss ongoing research and collaboration opportunities, as well as representatives from the IRB and biostatistics. 
  • Body Imaging Teaching ConferenceThursdays at 8AM. Weekly didactic conference focused on fellow education, with a broad range of topics led by Abdominal Imaging attendings and other guest speakers.
  • Journal Club: Fellows present at quarterly journal clubs which are integrated into the Interesting Case Conference, with robust discussion on the latest evidence-based guidelines.
  • Quarterly Prostate Rad/Path Conference
  • Numerous Interdisciplinary Conferences and Tumor Boards: Fellows are involved in case preparation and presentation with attendings in selected conferences.
  • Monthly Grand Rounds
  • Annual John A. Evans Alumni Day Symposium: Fellows are provided coverage and funding to attend the annual day-long course and reception, which addresses current hot topics including innovation and challenges within radiology. Recent course topics have included artificial intelligence, physician wellness, radiologist visibility, social media use, and global health.
  • NYRS Annual Meeting: Fellows are provided coverage and funding to attend the multi-day educational conference.
  • Additional educational conference funding and conference time is available for an individually tailored educational experience.


Fellows have the opportunity to participate in the daily training of residents and medical students, and to give clinical lectures to ultrasound technologists, residents, and medical students. Fellows hone their teaching skills by preparing case-based and didactic lectures.


Vacation/Conference Time

Each fellow is allotted 20 days of vacation (which can be taken by the day or the week), 5 days of conference time, with additional time allotted for interviews.



A competitive salary is provided with opportunities for moonlighting and extra compensation, subject to change. A generous book fund is provided, with additional conference funding available. Additional wellness benefits include ClassPass subscriptions and several social events that occur throughout the year, ranging from monthly happy hours to welcome and graduation receptions.


Combined Cardiothroacic/Abdominal Imaging Fellowship

Positions for a combined Cardiothoracic/Abdominal Imaging fellowship are available, with half of the academic year dedicated to Cardiothoracic Imaging and half of the academic year dedicated to Abdominal Imaging.
