Delay in diagnosing these pathologies can lead to significant morbidity and mortality in terms of ischemia and perforation of bowel. Multi detector computed tomography (MDCT) with intravenous contrast is an accurate and reliable imaging modality allowing prompt diagnosis and management. We present an overview of the radiological features found in acute presentations of different types of colonic volvuli.展开更多

Early diagnosis is absolutely necessary to minimize morbidity whereas delayed or missed diagnosis can cause adverse consequences. Computed tomography is a highly accurate imaging technique for diagnosing appendicitis. Hence it plays a valuable role in selected patients with suspected appendicitis;[1]. In this essay, we review the normal Computed tomography anatomy of the appendix and the right lower quadrant and illustrate the Computed tomography signs of appendicitis and important differential diagnostic entities. The Computed tomography appearance of complications of acute appendicitis is also presented, as are issues concerning clinical presentation and duration of the symptoms. Computed tomography signs can be varied and overlooked as they say what is easy to see is also easy to miss.展开更多
