目的：记录10年期间（1997-2006）在一个学术机构的妊娠患者的放射成像的利用情况。材料和方法：该研究由医院机构审查委员会批准，符合HIPAA。放弃知情同意。在作者所在的机构，成像期间暴露于辐射的怀孕患者被记录在医学物理部门编制的数据库中。作者回顾性审查了该数据库，以记录1997年至2006年期间的患者数量、每种影像学检查的数量、检查日期和估计的胎儿辐射剂量。作者搜索该机构的医疗记录，以获得每年的分娩总数作为控制的总怀孕patient population.Results：在10年期间，5270检查进行了3285怀孕患者（平均年龄，28岁）。患者和检查人数从1997年的237名患者接受331项研究增加到2006年的449名患者接受732项检查，患者人数增加了89%，检查人数增加了121%。按分娩计算的怀孕患者总数增加了7%，从1997年的8 661人增加到2006年的9 264人。从1997年到2006年，所有放射检查的利用率（每1 000次分娩的检查）增加了107%。传统放射线检查的数量平均每年增加7%，核医学检查每年增加12%，计算机断层扫描（CT）检查每年增加25%。每次检查的平均估计胎儿辐射暴露为0.43 mGy（范围，0.01-22.5 mGy），常规X线摄影，4.3 mGy（范围，0.01-43.9 mGy），CT，0.40 mGy（范围，0.01-7.7 mGy）用于核医学检查。与1997年至2006年相比，1997年至2006年，妊娠患者的放射利用率增加了107%。增加最多的是CT。
Purpose: To document the utilization of radiologic imaging in pregnant patients at one academic institution during a 10-year period (1997-2006).Materials and Methods: The study was approved by the hospital institutional review board and was compliant with HIPAA. Informed consent was waived. At the authors' institution, pregnant patients exposed to radiation during imaging are recorded in a database compiled by the medical physics department. The authors retrospectively reviewed this database to document the number of patients, number of each type of imaging examination, date of the examination, and the estimated radiation dose to the fetus from 1997 to 2006. The authors searched the institution's medical records to obtain the total number of deliveries by year as a control for the total pregnant patient population.Results: During the 10-year period, 5270 examinations were performed in 3285 pregnant patients (mean age, 28 years). The number of patients and examinations increased from 237 patients undergoing 331 studies in 1997 to 449 patients undergoing 732 examinations in 2006, an increase of 89% in patients and 121% in examinations. The total number of pregnant patients measured by deliveries increased 7%-from 8661 in 1997 to 9264 in 2006. Utilization rates (examinations per 1000 deliveries) of all radiologic examinations increased 107% from 1997 to 2006. The number of conventional radiographic examinations increased by an average of 7% per year, nuclear medicine examinations by 12% per year, and computed tomographic (CT) examinations by 25% per year. The average estimated fetal radiation exposure per examination was 0.43 mGy (range, 0.01-22.5 mGy) for conventional radiography, 4.3 mGy (range, 0.01-43.9 mGy) for CT, and 0.40 mGy (range, 0.01-7.7 mGy) for nuclear medicine examinations.Conclusion: For the comparison of 1997 to 2006, the radiologic utilization rate in pregnant patients increased by 107% from 1997 to 2006. The greatest increase was in CT.
