Brain morphology was examined using magnetic resonance imaging in 30 first-episode patients with a schizophreniclike psychosis, 15 chronic schizophrenics, and 20 neurological controls. Statistical analyses of computer-generated measurements of regions of interest were controlled for gender, age, social class, and total brain volume. Lateral ventricular size(More)
Diffuse pulmonary uptake of radiogallium was observed in 50 out of 510 scans (9.8%) performed in a general hospital over a period of 1 yr. Of the 50 cases, 80% had bilateral, diffuse distribution, and 20% unilateral. A variety of clinical conditions produced a similar picture on the pulmonary images. The most common cause of the diffuse uptake was(More)
Dual radionuclide imaging of the neck (Tc-99m pertechnetate and TI-201 thallous chloride) was performed in 22 patients with chemical evidence of hyperparathyroidism (elevated blood calcium and parathormone [PTH] levels). Of these, 19 of 22 had localization of a TI-201 "excess" area on radiothallium-radiotechnetium subtraction images. In 13 patients who have(More)
Hepatobiliary scintigraphy is an established method for the diagnosis of a bile leak from the biliary system. A bile leak should be considered in any patient after cholecystectomy who has unexplained abdominal pain after operation. Three patients with bile leak diagnosed by scintigraphy are described, one of whom had an unusual pattern of hepatic(More)
Bone scintigraphy is a sensitive imaging modality for detecting early lesions and polyostotic involvement in fibrous dysplasia. Common findings include multiple areas of focal uptake that are often unilateral and typically involve the ribs, tibia, femur, and craniofacial bones. A knowledge of various skeletal manifestations of fibrous dysplasia is helpful(More)
Single photon emission computerized tomography (SPECT), was performed on a female with an acutely painful knee. She had been on corticosteroids just before the onset of symptoms. Radiographs and planar scintigraphic views of the knees were unremarkable. SPECT images of the knees were instrumental in the diagnosis of avascular necrosis of the knee. The cases(More)
We studied 20 women who were at risk for osteoporosis (postmenopausal, or on dialysis, or on steroids), who presented with severe back pain. Patients underwent a dual photon (153Gd) densitometry study of the L2-L4 vertebrae, as well as an emission bone scan (99mTc-MDP). The dual photon method revealed abnormal results (20% or more below the mean expected(More)
Radionuclide cisternography is routinely performed for assessment of normal and abnormal pathways and the hydrodynamics of cerebrospinal fluid (CSF). An unusual case of a woman in whom cisternography provided the diagnosis of an iatrosenic spinopleural fistula with a large CSF collection in the pleural cavity, following surgical resection of a vertebra for(More)
Dynamic radionuclide cerebral angiography was performed in 14 patients with suspected brain death. In 10 of 14 patients, no intracranial arterial perfusion was demonstrable, thus confirming brain death. In four patients, faint venous activity was seen in the sagittal sinus only. All these patients also eventually died. Radionuclide cerebral angiography(More)
