fig. 1. Representative SS-EPI images of a 67-year-old female with primary hyperparathyroidism. A: STIR: A high-intensity mass on STIR was detected behind the right lobe of the thyroid gland.B: DWI with SS-EPI: A faint high-intensity lesion on DWI was detected in the corresponding location on STIR. The image was scored to be impossible to evaluate by two readers. C: ADC map: A high value was detected on the ADC map. The lesion was diagnosed as a PTA of the right superior gland. A 21 × 16 × 17 mm PTA was confirmed at surgery
Fig. 2. Representative RS-EPI images of a 72-year-old female with primary hyperparathyroidism. A: STIR: A high-intensity mass on STIR was detected behind the left lobe of the thyroid gland.B: DWI with RS-EPI: A high-intensity lesion on DWI was detected in the corresponding location on STIR. The lesion was evaluated as showing almost no or faint distortion. C: ADC map: A high value was detected on the ADC map. The lesion was diagnosed as a PTA of the left inferior gland. A 28 × 22 × 5 mm PTA was confirmed at surgery
