[CT-guided percutaneous biopsies]

The number of biopsy requests continuously increases over the years. Similarly, lesions that are not amenable to CT-guided biopsy are exceptional due to improved imaging guidance and technical advances. The needle tract should preferably go through fat, which is less painful and safer. The biopsy should be painless with the use of local anesthetics complemented by intravenous sedation. Blunt introducers and hydrodissection techniques create access to lesions without injury to vessels, bowel loops and fascias. The biopsy samples should be processed in accordance with the suspected diagnosis.
