摘要:

AbstractGray scale transrectal ultrasonography provides refined visualization of the texture of the prostate and other intrapelvic organs. Diagnostic accuracy of the transrectal scan has been successfully registered at 91% in benign prostatic hyperplasia, 85% in cancer, 89% in prostatitis, and 88% in total prostatic scans. Furthermore, prostatic calculi were visible in the tomograms of both normal and abnormal prostates at a higher frequency than generally considered. Other applications of ultrasonic control, such as during transurethral resection or cryosurgery of the prostate and staging of bladder tumors, are profitable using the gray scale technique.

摘要:

AbstractA 34 year old woman with bowel bypass surgery and persistent abdominal pain had intussusception of the blind loop, which was visualized on an abdominal ultrasound examination. The ultrasonic and radiographic findings are compared and presented. Ultrasound should prove to be an invaluable tool in evaluating abdominal pain in bowel bypass patients.

摘要:

AbstractThe typical echocardiographic features of mitral stenosis in association with an enlarged right ventricle and abnormal septal motion are generally consistent with pulmonary hypertension and functional tricuspid regurgitation. In the absence of clinical and echocardiographic features of pulmonary hypertension, the combination of mitral stenosis and “volume overload” of the right ventricle should alert the clinician to the diagnosis of Lutembacher's syndrome. This report discusses a patient with these echocardiographic findings in whom the diagnosis of Lutembacher's syndrome was confirmed by cardiac catheterizat

摘要:

AbstractTwo patients evaluated by ultrasound for abdominal masses were found to have thrombus within their central portal veins. Their cases are presented with angiographic correlation. Both are proven cases of hepatocellular carcinoma. The importance of evaluation of the portal vein in patients with liver neoplasms is discussed.
