CT scan uses multiple X-rays for generation of cross sectional images of the human body. Contrast agents can be used for enhanced delineation of anatomy. It is used for providing clinicians with images of real three dimensional anatomical structures. It has become the test of choice in diagnosing some urgent and emergent conditions like cerebral hemorrhage, pulmonary embolism, aortic dissection and appendicitis. Our centre is equipped with the state of art 128 slice CT scan (Siemens Somaton Definition Edge) with excellent spatial and contrast resolution. It is one of the best CT scans in the whole nation.
