What Is Interventional Radiology?

A medical subspeciality of Radiology that plays a vital role in both emergency and elective care, Interventional Radiology (IR) is the minimally invasive, image-guided treatment of certain diseases/ conditions that may otherwise require an open surgery.

IR procedures are performed with the help of advanced imaging modalities like MRI, CT and ultrasound scans, in cath labs/ sterile operation theatre environments. The interventional radiologist can see the inside of the body and treat complex conditions ranging from brain aneurysms to cancers, through very small incisions (2-3mm in 90% cases), with unmatched precision and speed.

Benefits of Interventional Radiology Procedures

  • Avoids major surgeries in certain conditions/ diseases
  • Mostly performed under local anaesthesia/sedation
  • Tiny incision, minimal scarring
  • Significantly lesser post-surgery pain
  • Minimal blood loss
  • Fewer post-surgical complications
  • Faster recovery
  • Shorter hospital stay/ same-day discharge for many procedures
