摘要:

We present two cases of subacute thyroiditis in which increased radionuclide activity in the affected areas was observed on201Tl thyroid scintigrams. These were taken to evaluate cold areas on the99mTc-pertechnetate thyroid scintigrams. This finding suggests that201TI may be a potentially useful radionuclide in visualizing inflammatory lesions.

摘要:

Bone scan findings are presented from five consecutive cases of metastatic osteogenic sarcoma. Every patient had pulmonary metastases which concentrated the bone imaging radiopharmaceutical to some degree. In one patient, the diagnosis of pulmonary metastasis was made prior to our seeing any radiographic abnormalities. The mechanism by which skeletal imaging agents localize in pulmonary lesions is not clear. Unsuspected skeletal metastases were also discovered on scans in two patients, both of whom had normal radiographs. Diagnosis of hypertrophic pulmonary osteoarthropathy was made in one patient with normal radiographs. These findings indicate that bone scans as well as radiographs should be performed routinely in preoperative staging and followup of patients with osteogenic sarcoma.

摘要:

Thirteen patients with neural crest tumors were each studied with a radionuclide skeletal survey, a radiographic skeletal survey, and an iliac crest bone marrow aspiration. The RN skeletal survey proved to be more accurate than the radiographic skeletal survey in: 1) detecting the primary tumor; 2) demonstrating bony metastatic disease; and 3) evaluating response to therapy. The overall accuracy of the RN skeletal survey in detecting metastatic disease correlated with the results of bone marrow aspiration both in the initial detection of metastatic disease and the evaluation of response during therapy.

摘要:

Spleen scan demonstration of space-occupying lesions in patients with histiocytic lymphoma is a sensitive but not a specific finding. However, response to therapy could be evaluated if pretreatment scans show welldefined space-occupying lesions and posttreatment scans showed resolution of those changes.

摘要:

Unusual bone and/or bone marrow images were visualized during a99mTc-Sn-DTPA renal dynamic study in a patient with acute leukemia. The possible mechanism of this phenomenon is discussed.

摘要:

The radionuclide, CAT and angiographic features of a case of herpes simplex encephalitis are present. A dramatic change in the abnormal perfusion and static concentration of tracer activity resulted following chemotherapy with Adenine®arabinoside. The improvement seen on the dynamic and static scintiscans correlates closely with the patient's clinical course and CAT findings. The radionuclide perfusion study is of particular importance in documenting the diminished activity of the inflammatory process following therapy.

摘要:

We present a case in which dramatic anterior midline uptake of99mTc-pertechnetate simulated a suprasellar tumor in a patient with sarcoid. The brain scan abnormalities proved to represent extensive hypothalamic and basal ganglia involvement by sarcoidosis.
