CT guided biopsy

CT guided biopsy is a type of image-guided biopsy. It is generally less commonly used than ultrasound-guided biopsy, however, in some anatomical areas, it has greater precedence, such as lung and bone biopsies.

CT guided biopsy requires good teamwork with radiographic staff as it is not truly dynamic like ultrasound-guided biopsies.

It may be performed using the 'CT fluoroscopy' capabilities of modern CT scanners or with the traditional step-wise approach.

CT biopsies are usually performed using a co-axial needle technique to gain a stable position through which the biopsy may be performed.
