The value of the bone scan in idiopathic regional migratory osteoporosis.

Idiopathic regional migratory osteoporosis is a self-limited entity of unknown origin, which has received little attention in the nuclear medicine literature. It is characterized by severe joint pain, typically in a hip, with normal laboratory and normal early radiographic findings. Spontaneous recovery occurs, but recurrence is frequent in another joint, often the opposite hip. Recurrence in the same joint has never been reported. The bone scan is shown to be positive with first symptoms and is important in the diagnosis and management of this entity. Three cases are presented.

False placenta previa: a clinical observation.

A misleading appearance of placenta previa was observed in three sonographic examinations of pregnant women. In these women the fetuses were in a transverse lie and the placentas were implanted on the anterior uterine wall. In these circumstances it appears possible for the lower anterior portion of the uterine wall and the attached portion of the placenta to falsely simulate placenta previa.

"Lunch syndrome," a bone-scanning artifact: case report.

After a photon-deficient area in the region of the stomach under the ribs on the left side was noted in some bone-scanning patients, a successful attempt was made to produce the artifact by having a cooperative patient eat a large lunch. The comparison of the scans before and after lunch showed the presence of a postprandial artifact in the area in question. It is important not to confuse this artifact with a space-occupying avascular mass in that part of the abdomen.

Radionuclide brain scan findings in superior sagittal sinus thrombosis.

Superior sagittal sinus thrombosis is a serious condition requiring early diagnosis. This paper presents our experience with two cases and describes the findings. In one case radionuclide brain imaging was the first study performed. In the other, the diagnosis was made at arteriography with scanning used for follow-up.

Patency evaluation of a LeVeen shunt using 99mTc-sulfur colloid.

The LeVeen shunt has proved valuable in relieving intractable ascites. It is however subject to failure in about 5--8% of cases. To our knowledge there are only three reports in the literature describing the use of nuclides to assess patency; two using 99mTc-sulfur colloid and one using 99mTc-albumin. The purpose of this paper is to add our experience to the data currently published and stress that late liver visualization may occur with an obstructed shunt.

Poorly differentiated lymphocytic lymphoma with ectopic parathormone production: visulization of metastatic calcification by bone scan.

Metastatic soft tissue calcification is known to occur in hypercalcemia and is usually present in the kidneys, stomach and lungs. 1--3 This case presents two unusual features: 1) ectopic parathormone production in association with poorly differentiated lymphocytic lymphoma; and and 2) uptake of 99mTc-pyrophosphate in the liver in the absence of demonstrable abnormality at autopsy. The more usual sites of metastatic calcification also showed uptake of the radionuclide. We will discuss metastatic soft tissue calcification, ectopic parathyroid hormone production, hypercalcemia in malignancy and bone scan agent localization in soft tissues.

Tumor detection with 67Ga-citrate: a literature survey (1970--1978).

Gallium scan detection of various neoplasms is tabulated by anatomic and histologic categories. The experience with many neoplasms is sufficient to accurately predict the likelihood of detection with gallium. This tabulation helps to point out other areas where the cumulative experience is insufficient to accurately predict sensitivity rates.

Bone scans in condensing osteitis of the clavicle.

Two additional cases of condensing osteitis of the clavicle are reported. Technetium Tc 99m phosphate bone scans were positive in both cases. Clinical and roentgenographic manifestations may allow nonoperative diagnoses of this entity which mimics metastatic disease on bone scans.

Value of routine flow studies in nuclide brain scanning.

Nuclide brain scanning offers a noninvasive means of obtaining dynamic information about intracranial disease. Lesions which could be missed without the flow study are described, and other instances in which the differential diagnosis is greatly improved by the use of the vascular sequence are demonstrated. We recommend the routine use of the flow study when performing brain scans.

A prospective study of plasma DNA in the diagnosis of pulmonary embolism.

To assess the usefulness of plasma deoxyribonucleic acid (DNA) detection in the diagnosis of pulmonary embolism (PE), we prospectively studied the frequency and duration of the occurrence of free plasma DNA in 23 patients with PE and in 49 patients with pneumonia, myocardial infarction, thrombophlebitis, or normal lung scans. Plasma DNA was detected in 19 of the 23 patients (83 per cent) with PE and in none of the 49 patients with other diagnoses. Eighteen of the 19 PE patients with free DNA had persistence of DNA on all subsequent sampling for up to 5 days. In this series, plasma DNA had a sensitivity of 83 per cent in the diagnosis of PE and was extremely specific for PE. Thus, detection of free plasma DNA may be useful as a rapid, noninvasive test to aid in the diagnois of PE.

Clinical evaluation of the Cleon imager.

We have compared bone images from a number of patients using three instruments. In 38 patients, Cleon body images were compared with whole-body rectilinear scans. Cleon images were also compared with scintillation camera images of the trunk or extremities of 31 patients and of the skull of 70 patients. The Cleon was superior to the rectilinear scanner in resolution, lesion detectability, and speed of scanning. The Cleon and gamma camera were comparable in lesion detection, but the Cleon was consdierably faster. Clinical studies and comparative evaluation are presented.

Acute viral hepatitis in adults. Comparison of the radioimmunoassay and counterimmunoelectrophoresis methods of detecting HbsAg.

We compared the radioimmunoassay (RIA) and counterimmunoelectrophoretic (CIE) methods in detecting hepatitis B antigen (HBsAG) in 407 acute and 336 convalescent sera of adults with viral hepatitis. The CIE method demonstrated that 41% of acute and 28% of 14-to 17-day serum specimens were HBsAg-positive. The RIA method demonstrated seropositivity in 60% of acute and 56% of convalescent specimens (P less than .001). Eighty-four percent of coded specimens initially positive for HBsAg by RIA were found to have subtype antigenic determinants d or y; 92% of the HBsAg-negative controls were negative for subtype antigens, confirming the specificity of the RIA test. RIA subtyping data corroborated earlier work with immunodiffusion techniques.

Distribution of gold Au 198 after intraperitoneal injection in animals.

The distribution of gold Au 198 after intraperitoneal administration in dogs and rats was determined by scans and tissue radioassays obtained 24 hours after injection. Relative activity and percent of injected radioisotope contained in different organs were calculated. The radioisotope was found to be heavily concentrated in mediastinal lymph nodes and liver, with liver uptake averaging 36.5% of the injected isotope 24 hours after injection. The use of therapeutic intracavitary radiocolloids should be reevaluated in light of possible excessive irradiation of the liver.
