DVIR Medical Students Electives


The Department of Vascular & Interventional Radiology (DVIR) invites all medical students to embark on a discovery journey of minimally invasive interventional procedures #MIIP as part of the refreshed DVIR Medical Student Elective.

This updated 2023 curriculum is a kaleidoscope that aims to maximise the experience of the student through 6 exciting themes fashioned in a resource and time efficient manner to allow you to see the best of Interventional Radiology #IRAD in Singapore.  Depending on the duration of your time with us, a specially curated program will be tailored by your supervising tutor to your educational needs. 

Goals and objectives of elective: 

    1. To expose the students to the wide range of imaging guided minimally invasive procedures performed by Interventional Radiologists.
    2. To help the student understand the basis, principles and techniques of the various types of interventions.
    3. To familiarize the student with the workflow of a multidisciplinary team in interventional radiology and how it supports the needs of the hospital.
    4. To participate in a short research or audit project to be completed by the end of the posting.
