What is Interventional Radiology?

Interventional Radiology (IR) is a sub-specialty of radiology, which involves performing a range of image guided procedures through a "pin-hole". Interventional radiologists are specially trained physicians who specialize in minimally invasive, targeted treatments. Interventional Radiology includes a vast range of procedures ranging from image-guided biopsy, PICC line (peripherally inserted central catheter) insertion, angioplasty to embolization to radiofrequency ablation of tumours. Most procedures are performed using percutaneous, image-guided approaches. These procedures replace traditional surgical techniques and are generally easier for the patient because they involve less risk, less pain, shorter hospital stay and shorter recovery time. Interventional Radiology can also have a life-saving role in the treatment of hemorrhagic emergencies.

What is Interventional Oncology?

Interventional Oncology (IO) is a sub-specialty of Interventional Radiology that uses imaging guidance to deliver minimally invasive therapies in cancer patients. It is considered the fourth pillar of cancer therapy alongside medical, surgical, and radiation oncology.

What is the role of the Interventional Radiology Outpatient Clinic?

The Interventional Radiology Outpatient Consultation Clinic will follow-up with patients who have undergone certain IR procedures. The IR clinic helps to optimize patient care by providing the interventional radiologist with the opportunity to meet the patient prior to the procedure and obtain a pertinent history and physical examination. The procedure can be explained to the patient and treatment options are discussed. Post-procedure follow-up is coordinated through the IR outpatient consultation clinic.

Interventional Radiology in Women's Health 

Interventional radiologists are able to provide minimally invasive therapies to an increasing number of women’s health issues such as uterine fibroids, pelvic congestion syndrome, osteoporosis of vertebral bodies and ovarian cyst aspirations. Uterine fibroids are usually benign growths which can be managed by blocking its blood supply in a non-surgical manner under image guidance. Pelvic congestion can be attributed to varicose veins of the pelvis, which can be sealed by IR embolization under image guidance.

Interventional Radiology in Men’s Health

Interventional radiologists are able to provide minimally invasive therapies to an increasing number of men’s health issues such as infertility, varicocele, and prostatic conditions. Varicose veins of the testicles can cause symptoms of pain and infertility and can be managed in IR with minimally invasive techniques.
