Dear applicants:

Welcome to the Diagnostic Radiology and Integrated Interventional Radiology programs at UT Southwestern!

Thank you for your interest in our residency programs. As Chief Residents, we have the honor and privilege of working with and representing our co-residents and engaging with those who have chosen to pursue a career in Radiology.

Under the leadership of our Diagnostic Radiology Program Director Dr. Karuna Raj, and our Interventional Radiology Program Director Dr. Manoj Kathuria, we strive to provide our residents with a robust and well-rounded experience. As residents we provide coverage at Parkland Memorial Hospital, Clements University Hospital, and Children’s Medical Center. All three hospitals are busy training hospitals where we get to experience a wide breadth of cases, from bread and butter radiology to highly subspecialized examinations and procedures. Our diverse training experience ensures residents graduate prepared to take on any career, whether in academics or private practice.

We thank you again for your interest in our program at UT Southwestern and we look forward to working with you in the next stages of your medical career! Feel free to contact any of us if you have any questions about the program.
