Objective. The study aims to evaluate the clinic feasibility of rapid parathyroid hormone (PTH) detection and nano-carbon technology in preoperative diagnosis and localization of parathyroid adenoma. Methods. With the guidance of ultrasound, the operator performed the parathyroid puncture and tested the PTH value by using a PTH test kit, and then injected nano-carbon into parathyroid adenoma as a marker to observe whether the parathyroid adenoma was stained black during the final operation. Meanwhile, a part of excised specimen was made into homogenate and detected rapidly again by using the PTH test kit. The remaining was confirmed by intraoperative frozen pathological examination. Result. The sensitivity (12/12) of preoperative diagnosis was significantly higher than that of ultrasound (6/12), magnetic resonance imaging (7/12), and MIBI (9/12). During the operation, we found that the inner part of the parathyroid adenoma was stained black, and the PTH value of the specimen homogenate confirmed as parathyroid adenoma was more than 3000 pg/mL. Conclusion. This novel technology, as a very positive method for localization of parathyroid adenoma, plays an important role in guaranteeing the surgical reliability of parathyroid adenoma with help of nano-carbon technology.
