Fig. 4From: Rapid development of metastatic pulmonary calcifications in primary hyperparathyroidism: a case report and literature reviewRepresentative 99mTc-MDP bone scintillation images showing pulmonary calcification. The patient was intravenously injected with 740–925 MBq 99mTc MDP and emptied the bladder after 3 h. A SPECT instrument was used, which was equipped with a parallel low-energy high-resolution collimator. Anterior and posterior views were imaged at same time with scanning speeds of 15–20 cm/min and matrix 1024 × 256 pixelsBack to article page
