  • Abnormal collections

CT GUIDED PROCEDURES OF

  • Bone / spine
  • Lung mass
  • Deep critical lesions
  • Radiofrequency ablation / Microwave ablation
  • Drains

  • Direct live visualization
  • Error free
  • Less /no pain

What happens during an Ultrasound-guided Biopsy?

  • You will be lying down on an examination table and a local anesthetic will be administered. You will be awake for the entire procedure.
  • USG: Lesion is localized and a needle will be inserted after anesthesia. The needle will be carefully inserted and a tissue sample will be collected, several samples may be required. The entire process will be guided by ultrasound imaging.
  • CT: Here the lesion is localized using CT scan and needle is placed, adjusted and confirmed on repeating short scans and sample is collected.

Is the procedure painful?

Good local anesthesia will be given so that it is totally pain free or to the maximum you feel it like an injection experience as like taking a normal injection on the shoulder.

Post procedure Instructions
