Abstract: Objective To assess the diagnostic values of 99 mTc-MIBI SPECT/CT planar imaging and tomographic imaging in preoperative primary hyperparathyroidism (PHPT). Methods A total of 78 patients in Beijing Chaoyang Hospital from 2019 to 2021 with suspected PHPT who underwent pre-operative99mTc-MIBI SPECT/CT from January 2019 to January 2021 were retrospectively reviewed.The diagnostic efficacy of early planar imaging, late planar imaging, and tomographic imaging were calculated respectively.The results were compared by χ2 test. Results Of all the 78 patients, 20 males (25.64%) and 58 females (74.36%) were included, aged 14-78 (49.36±14.21) years old.Postoperative pathology confirmed 75 patients with PHPT.At patient level, the sensitivity, specificity, and accuracy of early planar imaging were 60.00%, 66.67%, and 60.26%, respectively.The sensitivity, specificity, and accuracy of late planar imaging were 81.33%, 0%, and 78.21%, respectively.The sensitivity, specificity, and accuracy of tomographic imaging were 89.33%, 66.67%, and 88.46%, respectively.The sensitivity and accuracy were significantly higher in late planar imaging and tomographic imaging than that in early planar imaging (χ 2=8.233,P=0.004 and χ 2=17.058,P < 0.001, χ2 =5.898,P=0.015 and χ2=16.272,P<0.001, respectively).At lesion level, the sensitivity, specificity, and accuracy of early planar imaging were 55.42%, 83.33%, and 57.30%, respectively.The sensitivity, specificity, and accuracy of late planar imaging were 73.49%, 16.67%, and 69.66%, respectively.The sensitivity, specificity, and accuracy of tomographic imaging were 90.36%, 66.67%, and 88.76%, respectively.The sensitivity was significantly higher in late planar imaging than that in early planar imaging (χ2=5.916, P=0.015).The sensitivity and accuracy were significantly higher in tomographic imaging than that in early planar imaging and late planar imaging (χ2=25.639, P < 0.001;χ2=22.364, P < 0.001 and χ2=7.975,P=0.005 and χ 2 =9.860,P=0.002, respectively). Conclusion The diagnostic values of 99 mTc-MIBI late imaging in preoperative primary hyperparathyroidism is more significant than that of early imaging.The late tomographic imaging can improve the sensitivity and accuracy.
