Early Specialization in Interventional Radiology (ESIR) is a training option for diagnostic radiology residents and medical students who identify an early desire to specialize in interventional radiology.  

ESIR training is completed during a diagnostic radiology residency. It requires at least eight interventional radiology rotations, one ICU rotation, and up to three interventional radiology-related rotations during the R1(PGY-2) - R4(PGY-5) years. It also requires at least 500 interventional radiology or interventional radiology-related procedures.

ESIR candidates must still complete an independent IR residency to finish their IR training. Completion of the ESIR requirements allows advanced placement into the 2nd year of the independent IR residency, reducing the total training time to six years. Independent residency program directors do retain the authority to determine whether ESIR training was adequate for advanced placement in their program; however, requiring two year of independent residency training for a resident with ESIR will be uncommon. 


Applications will be reviewed by the interventional radiology program director and interviews will be conducted by the program director and members of the educational committee during the Radiology-2 year. Applicants will be assessed based on their interest in interventional radiology, skills developed through procedures and IR rotations, academic experience (Rad primer exams, faculty evaluations) and character. The process will be conducted in accordance with TUHSC Radiology and Graduate Medical Education regulations and will not discriminate based on race, ethnic origin, handicap, sex or age as required by law. The interviewers will produce an objective, numerical score based on these attributes and they will also provide a written statement of their personal assessment. The interviewers will then make a recommendation to the Diagnostic and Interventional Radiology program directors who will select the ESIR candidate by the end of block 11 of the Radiology-2 year.


One ESIR resident will be selected each year from the Radiology-2 class. A description of the ESIR application and selection process will be published in the Diagnostic Radiology Residency Handbook.
