The correct answer is that both CT guidance and ultrasound are commonly utilized to assist in guiding biopsies.

CT guidance provides high-resolution cross-sectional images of the body, which allow radiologists to accurately pinpoint the location of a tumor or abnormal tissue within various anatomical structures. This precision is crucial during a biopsy procedure to ensure that the sample taken reflects the area of interest and minimizes damage to surrounding tissues.

Ultrasound is also frequently used due to its real-time imaging capabilities, making it particularly beneficial for guiding biopsies in superficial tissues, such as in the abdomen or soft tissues. This modality allows the clinician to visualize the needle's trajectory during the procedure, ensuring accurate placement.

The use of both techniques exemplifies the versatility and effectiveness in providing guidance during biopsies, accommodating various patient conditions and anatomical challenges.
