To investigate the knowledge and expectations of abdominopelvic MR elastography (MRE) among radiologists from multiple institutions, and to rate the image quality of MRE maps.
Radiologists from Beijing and Tianjin were invited to participate in an online survey. Full MRE maps of the uterus, prostate, pancreas, liver, and kidney from 93 research papers published between 2017 and 2024 were displayed for image quality rating, blinded to the MRE systems. Before and after the image-review session, the participants' knowledge and expectations about abdominopelvic MRE were investigated.
Eighty-one radiologists finalized the survey, all but one from tertiary hospitals. Their knowledge of MRE mainly came from the literature and conferences, and only 29.6% had hands-on experience. Additional setup and scanning time, as well as patient safety and comfort, were the major concerns that may hinder MRE application. Parametric maps from two MRE systems were reviewed, and the pressurized air (PA) system exhibited consistently higher subjective image quality for all five abdominopelvic organs compared to the acoustic driver (AD) system (all p < 0.05). The participants' knowledge about MRE improved after the image-review session, whereas their expectation declined regarding its utility in abdominopelvic tumor detection, characterization, staging, and treatment monitoring. Technical unfamiliarity with MRE was high, with ignorance rates ranging from 42.0% to 64.2%.
There was limited knowledge and availability of MRE even in tertiary hospitals in China's capital region. Currently available MRE systems offer varying levels of anatomical details, and the PA system might be more advantageous for applications in abdominopelvic oncology.
Question The radiologists' current knowledge and expectations of abdominopelvic MRE remained poorly investigated, and the impact of MRE image quality was unknown. Findings There was limited knowledge and availability of MRE in China's capital region, and MRE systems didn't consistently achieve sufficient image quality for abdominopelvic oncology. Clinical relevance Although MRE holds promise for abdominopelvic oncology, its availability and familiarity among radiologists remain low, and the image quality of MRE maps is sometimes insufficient. System optimization and targeted education are essential for future integration into clinical practice.
调查多家机构的放射科医生对腹盆腔磁共振弹性成像（MRE）的了解程度和期望，并对MRE图谱的图像质量进行评分。
邀请北京和天津的放射科医生参与在线调查。展示了2017年至2024年间发表的93篇研究论文中子宫、前列腺、胰腺、肝脏和肾脏的完整MRE图谱，用于图像质量评分，对MRE系统进行盲法评估。在图像审查环节前后，调查参与者对腹盆腔MRE的了解程度和期望。
81名放射科医生完成了调查，除1人外均来自三级医院。他们对MRE的了解主要来自文献和会议，只有29.6%的人有实际操作经验。额外的设置和扫描时间，以及患者安全和舒适度，是可能阻碍MRE应用的主要担忧。对来自两个MRE系统的参数图谱进行了审查，与声学驱动（AD）系统相比，加压空气（PA）系统在所有五个腹盆腔器官上的主观图像质量始终更高（所有p<0.05）。图像审查环节后，参与者对MRE的了解有所提高，而他们对MRE在腹盆腔肿瘤检测、特征描述、分期和治疗监测中的效用的期望有所下降。对MRE技术不熟悉的情况很普遍，无知率在42.0%至64.2%之间。
即使在中国首都地区的三级医院，对MRE的了解和应用也有限。目前可用的MRE系统提供的解剖细节程度各不相同，PA系统在腹盆腔肿瘤学应用中可能更具优势。
问题 放射科医生目前对腹盆腔MRE的了解和期望仍未得到充分研究，MRE图像质量的影响尚不清楚。发现 在中国首都地区，对MRE的了解和应用有限，MRE系统在腹盆腔肿瘤学中未能始终获得足够的图像质量。临床相关性 尽管MRE在腹盆腔肿瘤学方面有前景，但其在放射科医生中的可用性和熟悉程度仍然较低，MRE图谱的图像质量有时也不足。系统优化和针对性教育对于未来融入临床实践至关重要。
