Screening for lung cancer in a fixed population by biennial chest radiography.

abstract：:Renal failure induced by intravenous iodinated contrast media is a frequent medical problem. While such cases are generally reported first by the clinician, the phenomenon can be seen even earlier by the radiologist. An abnormally persistent nephrogram is a sign of abnormal clearance, which in turn should alert the ph...

abstract：:When a 30-minute infusion is chosen for intravenous cholangiography, the optimal dose in subjects with normal and decreased hepatic function seems to be 0.6 ml/kg iodipamide. Delayed visualization of the ducts and gallbladder occurs in hepatic dysfunction, therefore, radiographs should be taken up to eight hours after...
