Radionuclide hepatobiliary imaging was performed on a patient with a longstanding history of scleroderma who presented with abdominal pain suggestive of biliary disease. Cystic duct patency was documented after 10 min with tracer accumulation in the second portion of the duodenum which failed to progress consistent with the duodenal hypomotility of scleroderma. The patient was given intravenous...

Two cases of heptatic hemangioma are reported in which multiple-radionuclide and ultrasound techniques were combined in the diagnostic process. Blood pool imaging rather than perfusion imaging proved to be the most definitive diagnostic procedure. The application of radionuclide and ultrasound studies in the differential diagnosis of focal lesions of the liver is discussed.

A dramatic case of occlusion of the right pulmonary artery is presented. The diagnosis was clearly established by means of a lung scan and a radionuclide pulmonary angiogram. The entire course of the disease process was followed by radionuclide studies with a gradual but persistent return to normal. Due to the preciseness of the evidence presented, contrast angiography was not.thought necessary.

Radionuclide conjugates or ricin A chain (RTA) immunotoxins that target pl85HER-2 have partially inhibited the growth of human ovarian cancer xenografts in athymic mice but generally have not cured mice bearing human tumor transplants. The present study was undertaken to explore whether a combination of ionizing radiation and an immunotoxin could exert additive or synergistic cytotoxicity in cu...

This article deals primarily with the selection criteria, production, and the nuclear, physical, and chemical properties of certain dual-purpose radionuclides, including those that are currently being used, or studied and evaluated, and those that warrant future investigations. Various scientific and practical issues related to the production and availability of these radionuclides is briefly a...

SI out-patients presenting with calf-vein thrombosis were randomized to treatment with hepann for five days or heparin with subsequent warfarin for three months. Among 23 patients in the warfarin-group no recurrence occured, whereas 8 of the 28 patients (29%) in the non-warfarin group had recurrent thrombo-embolism during the first 90 days. It is concluded that patients with symptomatic calf-ve...

OBJECTIVE To evaluate the efficacy and safety of two subcutaneous prophylactic regimens for postoperative deep vein thrombosis after total hip replacement. DESIGN Prospective open randomised multicentre trial. SETTING 28 European departments of orthopaedic surgery. INTERVENTION All patients had bilateral phlebography 10 days after surgery. 31 patients receiving low molecular weight hepari...

Background. The objective of this study was to develop a simple ultrasound method for measuring thrombus regression in patients with proximal deep-vein thrombosis (DVT) and to test its utility for the detection of DVT recurrence. Methods and Resuls. The study comprised a cross-sectional survey and a prospective investigation (149 and 145 patients, respectively). In both phases, the normalizatio...

  Introduction: Using beta emitter radionuclide is a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. The aim of this research is to evaluate the tissue response to beta rays of 166Ho and determine the feasibility of beta emitting radionuclide for treatment of skin cancers. Methods: In this...
