Image-guided diagnosis and minimally invasive cancer care
Interventional radiology can play an important role in cancer care by helping diagnose tumours and, in selected cases, deliver treatment directly to them. Image guidance allows procedures to be planned and performed with precision while targeting the area of concern.
Dr. Yugal Goyal provides interventional oncology services in Siliguri, including image-guided biopsies, targeted intra-arterial therapies and tumour ablation procedures.
When a tissue or cell sample is needed to investigate a suspected tumour, imaging can be used to guide the needle to the area of concern.
Depending on the location and clinical requirement, procedures may include FNAC and tru-cut biopsy of areas such as the lung, liver, soft tissue or bone.
Image guidance helps target the required area while avoiding nearby structures where possible.
Transarterial Chemoembolization (TACE) is a minimally invasive procedure used in selected liver cancers. A catheter is guided through the blood vessels to the arteries supplying the tumour, allowing treatment to be delivered directly to the targeted area along with embolization.
Transarterial Radioembolization (TARE) is another catheter-based treatment used in selected liver cancers. It delivers radioactive microspheres through the tumour's blood supply to target the tumour from within.
The suitability of TACE or TARE depends on the type and extent of the tumour and the patient's overall condition.
Radiofrequency Ablation (RFA) uses controlled heat to destroy targeted tumour tissue. A specialised probe is positioned within the tumour using imaging guidance.
RFA may be considered for selected localised tumours when a minimally invasive treatment approach is appropriate.
Microwave Ablation (MWA) uses microwave energy to generate heat and destroy targeted tumour tissue. Like RFA, the treatment is performed by placing an ablation probe into the target area under imaging guidance.
Depending on the case, tumour ablation may be considered for selected liver, lung and renal tumours.
Some tumours have a significant blood supply. In selected cases, embolization may be performed before surgery to reduce blood flow to the tumour and potentially help reduce blood loss during the operation.
The procedure involves guiding a catheter into the vessels supplying the tumour and delivering embolization material to reduce that blood supply.
Some patients undergoing cancer treatment require reliable venous access for repeated medication or chemotherapy administration.
Image-guided placement of devices such as PICC lines and Port-A-Cath systems can provide longer-term vascular access when clinically appropriate.
Interventional oncology is often part of a wider cancer treatment plan. The appropriate procedure depends on the tumour type, location, stage, previous treatment and overall health of the patient.
Imaging findings and the patient's clinical information are considered before deciding whether an interventional treatment is appropriate.
Interventional oncology uses image-guided, minimally invasive procedures to diagnose or treat selected cancers.
It is a biopsy performed using imaging guidance to accurately direct a needle into a suspected tumour or abnormal area and obtain a sample for diagnosis.
TACE is a catheter-based treatment in which chemotherapy and embolization are delivered through the blood vessels supplying a selected liver tumour.
Tumour ablation uses techniques such as radiofrequency or microwave energy to destroy targeted tumour tissue. It may be suitable for selected localised tumours.
Not always. Interventional procedures may be used alongside surgery, systemic treatment or other cancer therapies. The appropriate treatment depends on the individual patient's condition and multidisciplinary assessment.
