CPT^® 77014, Under Computed Tomography Guidance

With the patient lying still on the examination table, the table moves through middle of the round CT scanner. The X–ray machine in the circular scanner produces narrow beams of X–rays (1–10 mm of thickness) that pass through specific parts of the patient's body. Different tissues of the human body absorb different amounts of X–rays. The electronic ray detectors detect the amount of radiation absorbed into the body. A special computer program processes the acquired data to create two–dimensional cross–sectional images of the targeted anatomical site which are displayed on computer monitor. This image is interpreted by a radiation oncologist or other specialist physician who can determine the tissue's condition (normal or diseased). In case of malignancy, the physician can determine the volume of the treatment field where the radiation needs to be applied, and also the healthy tissue area which should be protected from radiation.
