Radionuclide bone imaging as a means of differentiating loosening and infection in patients with a painful total hip prosthesis.
Twenty patients with 23 painful total hip prostheses were examined by radionuclide imaging (20 cases), arthrography (11 cases), needle aspiration (9 cases), and surgery (19 cases) for the purpose of assessing loosening and/or infection. Bone imaging was most accurate, showing three main distributions of activity: (a) ectopic calcification, (b) focal increased activity at the upper and lower ends of the femoral prosthesis, and (c) diffuse activity. These findings suggest that infection and loosening can be differentiated in many instances. None of the patients with focal activity had infection, compared to 2 of the 3 patients with diffuse uptake.

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.

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.
