1. In patients with chronic liver disease, magnetic resonance (MR) imaging was more sensitive than computed tomography (CT) for the diagnosis of hepatocellular carcinoma (HCC) when considered on a per-lesion basis. 2. The sensitivity of both imaging methods was significantly lower among HCCs less than one centimeter in diameter when...
1. Among patients with abnormal findings on outpatient chest x-ray who subsequently underwent chest computed tomography (CT) based on radiologist recommendations, a substantial percentage of abnormalities requiring treatment or further diagnostic work-up was detected. Evidence Rating Level: 2 (Good)            Study Rundown: Chest x-ray is the most...
1. In patients undergoing partial hepatectomy, pre-operative CT scans of liver parenchyma revealed less homogenous texture in patients who went on to develop hepatic insufficiency post-operatively. 2. Pre-operative texture analysis of CT scans may be useful in risk stratification for post-operative hepatic insufficiency. Evidence Rating Level: 3 (Average) Study Rundown: Post-operative liver...
1. In the evaluation of focal mass-like findings in the sigmoid colon on computed tomographic (CT) colonography, segmental bulging and the absence of diverticula strongly predicted carcinoma over chronic diverticular disease. Evidence Rating Level: 3 (Average) Study Rundown: Computed tomographic (CT) colonography is a non-invasive method of evaluating for polyps and...
1. The use of dual-energy computed tomography (CT) significantly improved the conspicuity of hypoperfused bowel segments relative to healthy adjacent tissue in a swine model of acute small bowel ischemia. Evidence Rating Level: 3 (Average) Study Rundown: Early detection of acute bowel ischemia is of critical importance as mortality is significantly...
Originally published by Harvard Health. What Is It? Computed tomography, also called CT or CT scan, is a process that uses X-rays and computer technology to make cross-sectional images of the body. A series of X-ray pictures, each a thin slice, are put together in a computer to form a three-dimensional view...
