Interventional Radiology Thesis Topics

Interventional radiology is a rapidly evolving superspeciality that uses image guidance for minimally invasive vascular and non-vascular procedures, including complex oncologic, neurovascular, hepatobiliary, genitourinary and emergency interventions. This page lists one hundred practical Interventional Radiology thesis topics suitable for DM Interventional Radiology, Fellowship in Interventional Radiology and FNB Interventional Radiology residents in India, as well as trainees preparing for Gulf Cooperation Council (GCC) interventional radiology research, Arab Board radiology dissertations and advanced IR fellowships.

The topics below are framed as observational, cross sectional and comparative clinical studies which are feasible in high-volume Indian and GCC centres, with realistic caseloads and routinely available imaging modalities such as ultrasound, computed tomography, magnetic resonance imaging and fluoroscopy. They are search-optimised for Interventional Radiology thesis topics, DM Interventional Radiology dissertation topics, interventional radiology research topics for India, GCC Interventional Radiology projects and Arab Board radiology thesis ideas.
