11C-Choline PET/CT images of a patient with a parathyroid adenoma 20-min p.i. with varying acquisition times. a Transverse PET image of 1-min acquisition, b 2.5-min acquisition, c 5-min acquisition, and d 10-min acquisition. a and b appear “noisier” than c and d. e Corresponding transverse image of low-dose CT, and f PET/CT fusion image with 5-min PET acquisition time. g Maximum Intensity Projection (MIP) PET image of 5-min acquisition at 20-min postinjection images of patient number 1 (Table 1). Note the physiological uptake in the salivary glands, and remaining activity in the vessel used for injection of the tracer. Also, slight uptake is seen in a thyroid nodule in the left thyroid lobe
