Interventional Radiology: Minimally Invasive Treatment, Guided by Imaging

Modern medicine is moving toward treatments that are safer, less invasive, and allow quicker recovery. Interventional Radiology (IR) is exactly that — using real-time imaging to treat conditions through a tiny incision instead of open surgery.

At Healthcare Ultrasound and Diagnostics, this is led by Dr. Niyati Sharma, an interventional and diagnostic radiologist with advanced fellowship training from the National University Hospital, Singapore, and former Head of Department and Senior Consultant experience at leading hospitals across India. If your doctor has recommended an image-guided procedure, you’re not being referred to a generalist trying their hand at it occasionally — this is Dr. Niyati’s specialty.

What is Interventional Radiology?

Instead of a large surgical cut, an interventional radiologist guides thin needles, catheters, or other instruments to the exact area of concern using live imaging — ultrasound, CT, fluoroscopy, or X-ray — as a real-time roadmap. The result is typically less pain, fewer complications, a shorter hospital stay, and faster recovery than the equivalent open surgery.

Procedures Dr. Niyati Performs

Dr. Niyati’s training spans a genuinely broad range of image-guided care — not just one narrow niche:

Vascular & neurovascular procedures Endovascular therapies, embolization, angioplasty, and stenting to diagnose or treat narrowed, blocked, or bleeding blood vessels — often replacing what would otherwise require open vascular surgery.

Hepatobiliary & oncologic interventions Including TIPS/DIPS (procedures that redirect blood flow in liver disease) and Y-90 radioembolization, a targeted, image-guided treatment used in liver cancer care. These are specialised procedures not widely available at every diagnostic centre.

Musculoskeletal procedures Including vertebroplasty for spinal fractures, alongside image-guided pain management delivered directly to the affected joint or nerve for greater accuracy than a blind injection.

Image-guided biopsy Precise needle sampling of suspicious lesions in the liver, lungs, thyroid, kidneys, or lymph nodes — performed under CT or ultrasound guidance.

Fluid drainage Removing infected or excess fluid from the abdomen, chest, or liver, guided by imaging to reach the right location with minimal disruption to surrounding tissue.

Complex vascular access For patients whose veins are difficult to access through standard methods.

Emergency image-guided care When conditions call for urgent, precise intervention rather than a scheduled procedure.

Why This Matters for You

Compared with conventional surgery, image-guided procedures typically offer:

Smaller incisions and less visible scarring
Reduced pain and lower infection risk
Minimal blood loss
Shorter hospital stays
Faster return to normal activity

The precision comes from the imaging guidance itself — Dr. Niyati can see exactly where the instrument is, in real time, throughout the procedure.

Is It Safe?

Interventional radiology procedures are performed under local anesthesia in most cases, with modern imaging equipment guiding every step. Dr. Niyati’s background — Singapore fellowship training, department-head experience, and active membership in ISVIR, CIRSE, and IRIA — reflects the level of specialist training this field calls for. She’ll walk you through what to expect, the risks specific to your case, and whether the procedure is the right fit before anything is scheduled.

Patients who’d prefer to discuss their case with a female specialist are welcome to request Dr. Niyati directly.

Consultation — Dr. Niyati reviews your case and explains the right approach
Procedure scheduled — with full pre-procedure guidance, and pricing confirmed for your specific case

Frequently Asked Questions

Is interventional radiology surgery? No. Most procedures involve a tiny skin puncture rather than a surgical incision.

Are these procedures painful? Most are performed under local anesthesia with minimal discomfort.

How long do procedures take? Typically 30 minutes to 2 hours, depending on complexity — Dr. Niyati will give you a clearer estimate for your specific procedure during consultation.

Can I request a female specialist? Yes — Dr. Niyati leads our interventional radiology practice, and patients are welcome to request her directly.

Is this available at both centres? Available in both Delhi and Agra; please confirm doctor’s availability for your specific procedure at our Agra centre when you reach out.
