Had the opportunity to moderate and present at the BALT Neurointervention NeuroEdge CME in Madurai.

The workshop saw active participation from radiology postgraduates, focusing on practical exposure and case-based learning in Neurointervention. It was encouraging to see strong interest among young radiologists, contributing to greater awareness of this evolving subspecialty.

A well-conducted and meaningful academic event.

Glad and honored to have delivered a talk on Mechanical Thrombectomy in Acute Stroke Interventions at the MGM Neuroradiology CME & Workshop, Chennai, in front of senior faculty and experts in interventional radiology.

A great experience interacting with colleagues and senior faculty and experts, and always fulfilling to teach young radiology mindsโ€”promoting awareness of interventional radiology.

Thankful to Dr. Aarthi Deepesh and IRIA for the invitation and for hosting an excellent academic conference.
