[Myocardial 99mTc-pyrophosphate scintigraphy in acute heart infarct].

50 consecutive patients hospitalized because of suspected myocardial infarction were examined by 99mTc-pyrophosphate scintigraphy. The scans were interpreted blind by one of the authors. There were positive results in 17 of 21 patients with myocardial infarction (sensitivity 0.

[Normocalcemic primary hyperparathyroidism. Skeletal scintigraphy findings indicated a metastatic malignant disease].

The article reports a patient with skeletal pain were radionuclide skeletal images (100 MBq 99mTc-methylenediphosphonate) suggested a metastatic neoplastic lesion as the underlying cause. Further examination revealed that the patient suffered from normocalcemic primary hyperparathyroidism, and after removal of an adenoma of the parathyroid gland the images normalised and the skeletal pain disappeared.
