a Of lesion removed during the operation at 60 and 90 minutes post administration.
b Of excised parathyroid adenoma on histopathology report; ‘anatomical’ refers to parathyroid adenomas identified in a typical position (e.g. close to the thyroid gland).
CCA, Common carotid artery; CT, computed tomography; FCH, 18fluorocholine positron emission tomography/CT; LN, lymph nodes; N/A, Not applicable; PTH, parathyroid hormone (1.8–6.8 pmol/l); Postop, postoperative; SUV, standardised uptake values.
