旨在阐明放射学研究（包括核医学和活检）在临床实践中对前列腺癌（PCA）诊断和分期的应用，并通过一项国际调查了解亚洲国家 PCA 的现状。亚洲前列腺影像工作组设计了包含四个领域的调查问卷，重点关注前列腺磁共振成像 (MRI)、其他前列腺成像、前列腺活检和 PCA 背景。该调查问卷被发送给韩国、日本、新加坡和台湾的111名专业会员，他们是其工作医院的代表，并对他们的答复进行了分析。本次调查的答复率为97.3%（108/111）。前列腺MRI使用3T扫描仪、解痉药、泻药、前列腺影像报告及数据系统报告的比例分别为21.6%-78.9%、22.2%-84.2%、2.3%-26.3%、59.5%-100% ， 分别。受访者报告使用 800-2000 秒/mm² 的最高 b 值和 9-30 厘米的视野。每月的前列腺 MRI 检查范围为 1 至 600 次，最常用于在日本和新加坡未经活检疑似 PCA 的患者，以及在韩国和台湾对已确诊 PCA 进行分期的患者。前列腺正电子发射断层扫描最常用的放射性示踪剂是新加坡的前列腺特异性膜抗原和其他三个国家的氟脱氧葡萄糖。前列腺 MRI 最常见的时机是活检前 (29.9%)。 63.8% 的医院进行了前列腺靶向活检，通常采用 MRI-超声融合方法。在这四个国家中，最常见的表现是局部 PCA，通常采用根治性前列腺切除术进行治疗。这项调查显示了评估 PCA 时的不同技术细节以及影像学和活检的可用性。这表明需要为亚洲放射科医生制定教育计划，以推广用于 PCA 诊断和分期的标准化循证成像方法。版权所有 © 2023 韩国放射学会。

To elucidate the use of radiological studies, including nuclear medicine, and biopsy for the diagnosis and staging of prostate cancer (PCA) in clinical practice and understand the current status of PCA in Asian countries via an international survey.The Asian Prostate Imaging Working Group designed a survey questionnaire with four domains focused on prostate magnetic resonance imaging (MRI), other prostate imaging, prostate biopsy, and PCA backgrounds. The questionnaire was sent to 111 members of professional affiliations in Korea, Japan, Singapore, and Taiwan who were representatives of their working hospitals, and their responses were analyzed.This survey had a response rate of 97.3% (108/111). The rates of using 3T scanners, antispasmodic agents, laxative drugs, and prostate imaging-reporting and data system reporting for prostate MRI were 21.6%-78.9%, 22.2%-84.2%, 2.3%-26.3%, and 59.5%-100%, respectively. Respondents reported using the highest b-values of 800-2000 sec/mm² and fields of view of 9-30 cm. The prostate MRI examinations per month ranged from 1 to 600, and they were most commonly indicated for biopsy-naïve patients suspected of PCA in Japan and Singapore and staging of proven PCA in Korea and Taiwan. The most commonly used radiotracers for prostate positron emission tomography are prostate-specific membrane antigen in Singapore and fluorodeoxyglucose in three other countries. The most common timing for prostate MRI was before biopsy (29.9%). Prostate-targeted biopsies were performed in 63.8% of hospitals, usually by MRI-ultrasound fusion approach. The most common presentation was localized PCA in all four countries, and it was usually treated with radical prostatectomy.This survey showed the diverse technical details and the availability of imaging and biopsy in the evaluation of PCA. This suggests the need for an educational program for Asian radiologists to promote standardized evidence-based imaging approaches for the diagnosis and staging of PCA.Copyright © 2023 The Korean Society of Radiology.
