Positive 131cesium scanning in parathyroid adenoma.

In a case of primary hyperparathyroidism, a palpable nodule, at the base of the right lobe of the thyroid, proved 'cool' during 99mTc scanning, but 'hot' when scanned with radiocesium. The uptake of this tracer was higher than the uptake of 75Seselenomethionine after suppression with T3. The authors discuss the possibility of cases of 'false-positive' radiocesium uptake in extrathyroid nodules, and in particular, the use of this tracer for the detection of parathyroid adenoma by scanning.

Quantitative bone scanning.

The use of a computer coupled on-line with the scintillation camera allows an improvement of the finding of skeletal scintigraphy realized with 99mTc-pyrophosphate, making possible the identification of the smallest bone lesions. It also makes possible the quantification of the uptake degree of the radioindicator demonstrating, in normal subjects, an uptake ratio between the various skeletal segments of 1.07 +/- 0.06. In 44 metastatic lesions the ratio was 1.80 +/- 0.32, whilst in 14 areas of slight hyperfixation of the tracer a value of 1.24 +/- 0.09 was found. Since we were dealing with patients suffering from metastatic bone neoplasms, the authors outline the possibility that the quantification of data will allow the demonstration of the bone metastases even more precociously than with traditional scintigraphix examination.
