Triple-compartment wrist arthrography is currently considered the optimal technique for evaluating carpal instability, because injection of contrast agent into the radiocarpal joint alone can fail to reveal ligamentous disruption due to a ball-valve tear. Unfortunately, triple-compartment arthrography can be time consuming for both the patient and the radiologist. This report describes a techni...

A prospective study was performed to evaluate in vivo the uniformity of cerebral distribution of iodinated contrast medium during slow intraarterial injection at rates used for chemotherapy installation in the internal carotid artery. We evaluated seven patients with primary intracranial neoplasms with routine film-screen angiography and with digital angiography during slow infusion. In six int...

Caudal epidural injection is a common intervention in patients with low back pain and sciatica. Even though the complications of fluoroscopically directed epidural injections are less frequent than in blind epidural injections, complications due to contrast media can occur. We report a case of anaphylactic shock immediately after injection of an intravenous nonionic contrast medium (iohexol) du...

Recently, we performed a contrast-enhanced thoracic 16-channel multi-slice computed tomography (CT) with intravenous (i.v.) administration of iodixanol [Visipaque, dose 0.5 g I/kg body weight (bw)] in a 73-year old patient, suffering from multiple myeloma and chronic renal failure (calculated creatinine clearance of 23ml/min). Three days later, an unenhanced CT of the upper abdomen was performe...
