Ultrasound is the imaging of deep structures in the body by recording the echoes or pulses of ultrasonic waves directed into the tissues. Fluoroscopy is the use of real time x-rays on a TV screen to see body structures. Computerized Axial Tomography (CAT scan) is the use of an x-ray beam which moves around the patient. A computer stores, interprets and generates an image onto a magnetic disk. The body image created can then be reconstructed through pictures in a cross section. How to Prepare for the Biopsy 1.
