To assess prospectively the agreement of magnetic resonance (MR) pulmonary perfusion with single-photon emission computed tomography (SPECT) perfusion for perfusion defects down to the subsegmental level in patients with suspected pulmonary embolism (PE).
In 41 patients with suspected PE, contrast-enhanced MR pulmonary perfusion (3D-FLASH, TR/TE 1.6/0.6 ms) was compared to SPECT perfusion on a per-examination basis as well as at the lobar, segmental, and subsegmental level.
The MRI protocol was completed in all patients, and mean examination time was 3 min 56 s. MR perfusion showed a very high agreement with SPECT (kappa value per examination 0.98, and 0.98, 0.83, and 0.69 for lobar, segmental, and subsegmental perfusion defects, respectively). Of 15 patients with PE, MR perfusion detected 14 cases.
The very high agreement of MR perfusion with SPECT perfusion enables the detection of subtle findings in suspected PE.
前瞻性评估磁共振（MR）肺灌注与单光子发射计算机断层扫描（SPECT）灌注在疑似肺栓塞（PE）患者中对低至亚段水平灌注缺损的一致性。
对41例疑似PE患者，将对比增强MR肺灌注（3D-FLASH，TR/TE 1.6/0.6 ms）与SPECT灌注在每次检查时以及叶、段和亚段水平上进行比较。
所有患者均完成了MRI检查，平均检查时间为3分56秒。MR灌注与SPECT显示出非常高的一致性（每次检查的kappa值为0.98，叶、段和亚段灌注缺损的kappa值分别为0.98、0.83和0.69）。在15例PE患者中，MR灌注检测出14例。
MR灌注与SPECT灌注的高度一致性使得在疑似PE中能够检测到细微发现。
