To evaluate the indications for performing magnetic resonance imaging of the female pelvis at a referral center for cancer.
This was a retrospective, single-center study, conducted by reviewing medical records and imaging reports. We included 1060 female patients who underwent magnetic resonance imaging of the pelvis at a cancer center between January 2013 and June 2014. The indications for performing the examination were classified according to the American College of Radiology (ACR) criteria.
The mean age of the patients was 52.6 ± 14.8 years, and 49.8% were perimenopausal or postmenopausal. The majority (63.9%) had a history of cancer, which was gynecologic in 29.5% and nongynecologic in 34.4%. Of the patients evaluated, 44.0% had clinical complaints, the most common being pelvic pain (in 11.5%) and bleeding (in 9.8%), and 34.7% of patients had previously had abnormal findings on ultrasound. Most (76.7%) of the patients met the criteria for undergoing magnetic resonance imaging, according to the ACR guidelines. The main indications were evaluation of tumor recurrence after surgical resection (in 25.9%); detection and staging of gynecologic neoplasms (in 23.3%); and evaluation of pelvic pain or of a mass (in 17.1%).
In the majority of the cases evaluated, magnetic resonance imaging was clearly indicated according to the ACR criteria. The main indication was local recurrence after surgical treatment of pelvic malignancies, which is consistent with the routine protocols at cancer centers.
评估在一家癌症转诊中心对女性骨盆进行磁共振成像检查的适应证。
这是一项回顾性单中心研究，通过查阅病历和影像报告开展。我们纳入了2013年1月至2014年6月期间在一家癌症中心接受骨盆磁共振成像检查的1060例女性患者。检查适应证根据美国放射学会（ACR）标准进行分类。
患者的平均年龄为52.6±14.8岁，49.8%为围绝经期或绝经后女性。大多数患者（63.9%）有癌症病史，其中29.5%为妇科癌症，34.4%为非妇科癌症。在接受评估的患者中，44.0%有临床症状，最常见的是盆腔疼痛（11.5%）和出血（9.8%），34.7%的患者之前超声检查有异常发现。根据ACR指南，大多数患者（76.7%）符合进行磁共振成像检查的标准。主要适应证为评估手术切除后肿瘤复发（25.9%）；检测和分期妇科肿瘤（23.3%）；评估盆腔疼痛或肿块（17.1%）。
在大多数评估病例中，根据ACR标准，磁共振成像检查有明确适应证。主要适应证是盆腔恶性肿瘤手术治疗后的局部复发，这与癌症中心的常规方案一致。
