What Diagnosis Can Be Determined From a CT Urogram?


Quick Answer

A computed tomography, or CT, urography is used as a primary imaging procedure to diagnose urinary tract conditions including hematuria, cancers and abnormalities such as kidney or bladder stones, according to the Radiological Society of North America. CT urograms can also provide information about other structures and conditions of the abdominal and pelvic regions.

CT urography utilizes specialized X-ray apparatus and advanced computer technology to generate cross-sectional images of the interior of the body, states the Radiological Society of North America. These images can later be analyzed on a monitor or printout and digitally stored. During a scan, as with traditional X-rays, radiation is directed at the area of the body being examined and absorbed in varying degrees by different structures within the body, allowing these structures to be distinguished from one another and identified. Unlike traditional X-rays, CT technology is capable of producing highly accurate, detailed images of different types of tissue in addition to bones, lungs and blood vessels.

During a scan, several different X-ray beams and electronic detectors encircle the body, measuring the absorption of radiation from multiple perspectives to collect and record a comprehensive volume of information, explains the Radiological Society of North America. Specially designed software processes this data into multiple two-dimensional cross-sectional images. These images are then digitally reassembled to create a highly detailed multidimensional representation of the internal structure of the body.
