Static and SPECT images were acquired at 15 min and 3 hours. Delayed CT- SPECT was performed.
Initial images show mild focal uptake in the region of the thyroid left upper and right lower poles. No other abnormal extra-thyroid uptake is detected in the rest of the neck or mediastinum. Delayed images show locally retained uptake corresponding to a soft tissue nodule posterior to the left upper pole and another little nodule posterior to the right lower pole. Mild uptake in sub centimetre left supraclavicular lymph nodes is non-specific. Mild uptake in the left anterior mediastinum is probably within physiological limits.
