A Dual-tracer subtraction of both 99mTc-pertechnetate and 99mTc-MIBI planar scans of a 37-year-old woman. A focal MIBI uptake is visualized below the lower pole of the left thyroid lobe, suggestive of adenoma of left lower parathyroid gland. B Axial view of the subsequent SPECT/CT images by the same patient, showing a round lesion with a diameter of around 11 mm with focal MIBI uptake localized to a single abnormal left lower parathyroid gland. The patient underwent minimally invasive parathyroidectomy for a single left lower parathyroid adenoma and experienced an appropriate drop in intraoperative parathyroid hormone.
