The purpose of this study was to evaluate the accuracy of dose information obtained from the digital imaging and communications in medicine (DICOM) using the study description for dose management in nuclear medicine (nuclear medicine SD), and to investigate the feasibility of nuclear medicine SD.
Single-photon emission nuclear medicine examinations and radionuclide therapy from June 1 to June 30 in 2021 (our hospital master period) and 2023 (nuclear medicine SD period) were included. The dose information in the radioisotope administration record was taken as the true value, and the agreement rate of the examination type, radiopharmaceutical, and dose in the dose management system and the error rate of the dose in the nuclear medicine SD period were calculated.
The agreement rate of examination type and radiopharmaceutical was improved from 37.5% to 97.0% by using nuclear medicine SD, and the agreement rate of dose was 54.0%.
The use of nuclear medicine SD has remarkably improved the integrity of dose information. Dose consistency can be improved by unifying the checking system and the input method of dose information. The feasibility of nuclear medicine SD seems to be high in many facilities, and it may contribute to information collaboration among multi-center facilities and enable centralization of dose management systems.
本研究旨在使用核医学剂量管理的研究描述（核医学SD）评估从医学数字成像和通信（DICOM）中获取的剂量信息的准确性，并探讨核医学SD的可行性。
纳入2021年6月1日至6月30日（我院主时期）和2023年（核医学SD时期）的单光子发射核医学检查和放射性核素治疗。将放射性药物给药记录中的剂量信息作为真值，计算剂量管理系统中检查类型、放射性药物和剂量的符合率以及核医学SD时期的剂量误差率。
使用核医学SD后，检查类型和放射性药物的符合率从37.5%提高到97.0%，剂量符合率为54.0%。
核医学SD的使用显著提高了剂量信息的完整性。通过统一剂量信息的核对系统和输入方法，可以提高剂量一致性。核医学SD在许多机构中似乎具有很高的可行性，它可能有助于多中心机构之间的信息协作，并实现剂量管理系统的集中化。
