Increased localization of 201 Tl-chloride in subacute thyroiditis.

We present two cases of subacute thyroiditis in which increased radionuclide activity in the affected areas was observed on 201 Tl thyroid scintigrams. These were taken to evaluate cold areas on the 99m Tc-pertechnetate thyroid scintigrams. This finding suggests that 201 Tl may be a potentially useful radionuclide in visualizing inflammatory lesions.

Utility of combined 99mTc-phosphate and 67Ga imaging in diagnosis of septic arthritis.

A case of septic arthritis diagnosed by combined 99m Tc-phosphate and 67Ga imaging, which preceded positive cultures of the infecting organism, is presented. A previously healthy 10-year-old girl complained of pain in her left hip with persistent fever. Initial laboratory studies showed a normal white cell count and negative blood cultures. A septic process was not confirmed. Blood flow studies and bone images with 99mTc-phosphate showed markedly increased perfusion in the left hip joint without extension to bone. Subsequent 67Ga images revealed a marked increase in radioactivity in the same region, indicating the presence of a septic process. Serial blood cultures and arthrocentesis showed Staphylococcus aureus. The patient improved on antibiotics.

Clinical application of 201Tl scintigraphy in patients with cold thyroid nodules.

201Tl-chloride scintigraphy was performed in 45 patients with cold thyroid nodules. The 201Tl scintigram was positive in 17 of 18 thyroid patients with cancer (94.4%), 8 of 20 patients with an ademoma (40.0%), 1 of 2 adenomatous goiter patients (50.0%), and all of 5 cases of chronic thyroiditis (100.0%). When the cold nodule was demonstrated to be positive with 201Tl, the statistical chance of the lesion being a cellular one was 100.0% and a risk of its malignancy was 54.8%. On the other hand, the nodule with negative 201Tl concentration had a 14.3% chance of cellularity and a 7.1% risk of malignancy. Thus, 201Tl scintigraphy is of use in the differential diagnosis of the cold thyroid nodule.

Detection of active bleeding from ruptured aortic aneurysm by emergency radionuclide angiography.

Radionuclide angiography of the abdominal aorta provides hemodynamic information of the kidneys, aorta and aneurysm as well as the location and extent of aneurysm. Visualization of early abnormal activity in the pelvic region simultaneously with iliac artery visualization is thought to be a specific finding of active bleeding from a ruptured aneurysm of the abdominal aorta.
