Optimization and Individualization of Diagnostic Scintigraphy Protocol and Minimally Invasive Radio-guided Parathyroid Surgery

Despite the relatively accurate preoperative topographic information, minimally invasive parathyroid surgery can still be very challenging, especially in the case of small adenoma in ectopic localization. Radioguided technique offers both help with in-vivo identification and ex-vivo confirmation of adenoma. Excellent ex-vivo radio guidance results are referred. But, in-vivo accuracy is most important but its results are not satisfactory. The aim of this study was to evaluate if there is a beneficial effect of individualized timing of surgery using preoperative multi-phase 99mTc-MIBI single-photon emission computed tomography (SPECT)/CT on in-vivo characteristics of minimally invasive radio-guided parathyroidectomy.
