ABSTRACT
Objective To evaluate the value of technetium-99m methoxy isobutyl isonitrile(99Tcm-MIBI) tomography and integrated CT scan in preoperative localization diagnosis of primary hyperparathyroidism (PHPT). Methods 31 patients with PHPT were selected .15 minutes and 90 minutes ( delayed images ) after intravenous administration of 99 Tcm-MIBI 370 MBq, static anterior planar images of the neck and chest were obtained .99 Tcm-MIBI tomography and integrated CT scan were acquired after the delayed images .All patients received neck ultra-sound scan before surgery .The imaging findings were compared to the pathological results .Results The detec-tion rate of hyperparathyroidism lesions of 99 Tcm-MIBI dual-phase imaging and 99 Tcm-MIBI tomography and regis-tration with integrated CT scan was 87.1%and 93.5%respectively, without statistical significance (P>0.05). However , they were both higher than ultrasound scan which had a detection rate of 64.5%.The differences had statistical significance (χ2 =4.039 and 7.884 respectively , P<0.05 ) .The detection rate of parathyroid hyper-plasia of 99 Tcm-MIBI tomography and registration with integrated CT was both 80.0%, higher than that of the ul-trasound test(40.0%)and 99Tcm-MIBI dual-phase imaging(40.0%).The fusion imaging with integrated CT scan provided detailed anatomy data and more information for surgical doctors .Conclusions 99 Tcm-MIBI tomography and registration with integrated CT scan can improve the detection rate of PHPT compared with 99 Tcm-MIBI dual-phase imaging , provide detailed anatomy data , and has high clinical value in preoperative localization diagnosis of PHPT.
