CT Scan

CT Scan

Computed Tomography (or CT) scanning (sometimes called CAT scanning) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Physician can diagnose problems such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and disorders of bone and muscle.

CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams. Physicians often use the CT examination to:

Advanced Imaging(1) often the best method for detecting many different cancers, including lung, liver, kidney and pancreatic cancer, since the image allows a physician to confirm the presence of a tumor and measure its size, precise location and the extent of the tumor's involvement with other nearby tissue. (2) to stage, plan and properly administer radiation treatments for tumors as well as monitor response to cancer treatments; (3) quickly identify injuries to the lungs, heart and vessels, liver, spleen, kidneys, bowel or other internal organs in cases of trauma; (4) to guide biopsies and other procedures such as abscess drainages and minimally invasive tumor treatments;

CT scan for cancer tumors(5) to plan for and assess the results of surgery, such as organ transplants or gastric bypass; (6) measure bone mineral density for the detection of osteoporosis; (7) for detection, diagnosis and treatment of vascular diseases that can lead to stroke, kidney failure or even death. CT is commonly used to assess for pulmonary embolism (a blood clot in the lung vessels) as well as for abdominal aortic aneurysms; (8) diagnosis and treating spinal problems and injuries to the hands, feet and other skeletal structures.
