Biopsy
Fine Needle Aspiration of thyroid nodules
A ultrasound-guided fine needle aspiration biopsy uses sound waves to help locate a nodule or abnormality within the thyroid and remove a tissue sample an examination under microscope. The procedure is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation.
Transjugular liver biopsy
Transjugular liver biopsy(TJLB) is a technique for obtaining liver biopsy without causing a transjugular injury. Using a transvenous approach, the biopsy needle is inserted into the liver into the liver via the hepatic vein, avoiding the peritoneum and the liver capsule.
