BACKGROUND/AIM: To determine whether a prototypical compressed-sensing volume-interpolated breath-hold (csVIBE) provides diagnostic value in detecting rectosigmoid infiltration in deep infiltrating endometriosis (DIE).
PATIENTS AND METHODS
csVIBE was employed in 151 women undergoing pelvic magnetic resonance imaging, of whom 43 had undergone surgery for suspected endometriosis. The accuracy of T2-weighted BLADE and BLADE/csVIBE, additional diagnostic value of csVIBE, and diagnostic confidence were rated by two readers. Additionally, the presence of the "mushroom cap sign" was assessed on BLADE and csVIBE.
RESULTS
The diagnostic accuracy, sensitivity, and specificity of BLADE and BLADE/csVIBE were not significantly different between Readers A and B. For both readers, the confidence in the diagnosis increased with csVIBE, but this increase in the odds ratio was not significant for both readers. Both readers preferred csVIBE over BLADE with regard to detection of the "mushroom cap sign."
CONCLUSION
csVIBE may provide a diagnostic benefit for surgical strategy selection through better delineation of the "mushroom cap sign."
背景/目的：旨在确定典型的压缩感知容积内插屏气（csVIBE）在检测深部浸润性子宫内膜异位症（DIE）直肠乙状结肠浸润中是否具有诊断价值。
患者与方法
151 名接受盆腔磁共振成像的女性患者中采用了 csVIBE，其中 43 名女性因疑似子宫内膜异位症而行手术治疗。两位读者对 T2 加权 BLADE 和 BLADE/csVIBE 的准确性、csVIBE 的附加诊断价值以及诊断信心进行了评分。此外，还在 BLADE 和 csVIBE 上评估了“蘑菇帽征”的存在。
结果
读者 A 和 B 之间，BLADE 和 BLADE/csVIBE 的诊断准确性、敏感度和特异性均无显著差异。对于两位读者，csVIBE 增加了诊断信心，但对两位读者而言，这种优势比的增加并不显著。两位读者均认为 csVIBE 比 BLADE 更能检测到“蘑菇帽征”。
结论
csVIBE 可能通过更好地描绘“蘑菇帽征”，为手术策略选择提供诊断获益。
