The exclusion of large endoscopic varices by CT, using standardized criteria, may obviate the need or frequency of EGD screening in select patient populations. Alternatively, CT findings highly suggestive of esophageal varices in cirrhotic patients may warrant further investigation and/or treatment. Further studies are needed to validate these findings.

Thin axial computerized tomography of the air distended bladder shows promise as a potential screening tool for bladder cancer. The low specificity of color mapped 3-D renderings makes the technique inappropriate for screening. It may valuable for guiding urologists to additional suspicious sites in a patient with a known tumor.

Improvements in CT technology, specifically with respect to the development of multi-row detector CT, have increased the ability to detect acute myocardial ischaemia. This case report details the finding of decreased myocardial enhancement on CT in a patient who complained of acute chest symptomalogy and was diagnosed with acute myocardial infarction, which was subsequently confirmed by cardiac catheterization. Given the variability of the clinical presentation of acute myocardial infarction, greater attention should be paid by radiologists to myocardial enhancement in patients with significant coronary risk factors, as evidence of acute myocardial infarct or ischaemia may be detected.
