IV contrast media are usually necessary for abdominal and pelvic scans, improving the detection and characterization of abnormalities.6 Contrast agents are generally not required for chest scanning if the examination is intended solely to evaluate lung parenchyma, but are frequently used to assess the mediastinum. Sonography also is used to evaluate scrotal disorders and abnormalities in the neck, including those of the thyroid gland. Clin Radiol 1984;35:347, 3. CT scans create images of bones and soft tissues. Interpretation of the abdominal radiograph depends on the assessment of the bowel gas pattern, solid organ outlines, a search for abnormal calcification, and a review of the skeleton. Maximal caliber of the transverse colon on plain films is taken to be 5.5cm in diameter, and the maximal cecal diameter is 9cm. Evaluate for infection and abdominal and chest trauma SPECT, or whole body imaging, often takes a long time, and children younger than 4 years may need to be sedated. The contrast medium used in GI and GU examinations, except for intravenous urogram studies, is either water soluble or a barium solution, given directly into the organ system to be evaluated.
