Answer:

The answer to the question: Which procedure uses a CT scan to pinpoint the location of a mass in three dimensions and guide the biopsy needle, would be, B: Stereotactic biopsy.

Explanation:

This procedure is mostly used in cancer diagnosis and cancer treatment and its purpose is to accurately locate tumor, particularly those that are atypical, and allow a doctor to extract necessary tissue from the tumor itself through biopsy. Because of the need to ascertain the exact location, size and structure of the tumor, CT scans are used to view in two planes the position in a three-dimensional space and exact biopsy is also favored by this procedure.
