This study compared prostate multiparametric MRI (mpMRI) performed using an 18-French rectal tube in place throughout the examination after initial placement by a technologist ( = 97) with mpMRI performed without rectal tube placement ( = 99). Acquisition parameters were otherwise identical. Two radiologists scored subjective image quality and measured rectal diameter. For both readers, rectal tube placement was associated ( < .001) with improved ADC map quality, decreased DWI distortion, decreased rectal gas, and decreased rectal diameter. Findings support routine rectal tube placement for prostate mpMRI.
本研究比较了在技术员最初放置后，在整个检查过程中使用 18 号直肠管（= 97 例）进行的前列腺多参数 MRI（mpMRI）与不放置直肠管（= 99 例）进行的 mpMRI。采集参数否则完全相同。两位放射科医生对主观图像质量和直肠直径进行评分。对于两位读者，直肠管的放置均与（<0.001）ADC 图质量改善、DWI 失真减少、直肠气体减少和直肠直径减小相关。这些发现支持在前列腺 mpMRI 中常规使用直肠管。
