Sensitivity of different imaging methods in localizing parathyroid lesion in PHPT.

	Pathology (no.)	Imaging (no.)	Sensitivity (95% CI)
USG	234	210	89.7% (85.0%–93.2%)
MIBI	180	164	91.1% (86.0%–94.8%)
USG or MIBI	238	229	96.2% (92.7%–98.1%)
CT	134	110	82.1% (74.3%–88.0%)
PET-CT	7	7	100.0% (56.1%–100.0%)

USG: cervical ultrasonography; MIBI: ^99mTc-MIBI SPECT/CT; CT: cervical contrast-enhanced CT scan; PET-CT: 18F-FDG PET/CT; USG or MIBI: applied either the cervical ultrasonography or ^99mTc-MIBI SPECT/CT.
