Multi-Detector Computed Tomography (MDCT) is a form of computed tomography (CT) technology for diagnostic imaging.  In MDCT, a two-dimensional array of detector elements replaces the linear array of detector elements used in typical conventional and helical CT Scanners.  The two-dimensional detector array permits CT scanners to acquire multiple slices or sections simultaneously and greatly increase the speed of CT image acquisition.  The development of MDCT has resulted in the development of high resolution CT applications such as CT angiography and CT colonoscopy.

CT scanning -- sometimes called CAT scanning -- is a noninvasive medical test that helps physicians diagnose and treat medical conditions.


CT imaging combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body.  These cross-sectional images of the area being studied can then be examined on a computer monitor or printed.


CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams. 


Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, trauma and muscoskeletal disorders. 


An ultrasound machine uses high frequency sound waves to create pictures of a variety of body structures including the internal organs of the abdomen and pelvis, the arteries and veins and the pregnant uterus and its gestation. 


Ultrasound is not usually used to assess bones or the intestines and unlike x-rays & CT scans, ultrasound does not use radiation, therefore, it may be used safely during pregnancy.
