This presentation discusses microwave ablation for treating tumors. Microwave ablation uses microwave energy to heat and destroy tumors without removing them. It can be used to treat tumors in the liver, lungs, kidneys, bones, prostate and thyroid. The key advantages are that it is faster than other ablation techniques, can treat larger tumors, and has lower recurrence rates. The presentation provides definitions of ablation and microwave ablation, indications and contraindications for the procedure, preparation steps, required materials, and case studies demonstrating its effectiveness.

Advantage
• Faster, which shortens anesthesia times
• Ability to treat larger tumors, as well as tumors
as small as 2 mm
• Fewer smaller probes, which leads to fewer
complications
• Simultaneously targets up to three tumors with
independent control of each probe
• Expanded treatment area allows microwaving of
tumors close to major arteries and veins

23. J Venkat, Prof in Radiography
Chennai India
Advantage
• Lower recurrence rates
• Specially designed kidney and bone probes
• Minimal risk to patient
• No pad need as RFA
• Typically little or no pain
• Short hospital stay

Take home message
• MW is a newer technology, which can
treat tumour in Radiology Dept (Diag)
• Tumours from Liver, Lung and Kidney
• Prostate and Thyroid tumours also can be
treated
• CT or USG guidance
