(1)背景：分节笛卡尔心血管磁共振（CMR）通常不能提供心律失常患者心功能的可靠评估。我们的目的是评估微小金角螺旋实时CMR序列在1.5 T时用于不规则心律患者左室（LV）容量测定的性能；(2)方法：我们对32例患者进行实时序列与标准屏气分节笛卡尔序列的验证，其中11例患者出现心律失常。评估舒张末期容积（EDV）、收缩末期容积（ESV）、卒中容积（SV）和射血分数（EF）。在心律失常患者中，实时和标准笛卡尔图像采集与参考超声心动图模式进行比较；(3)结果：在有窦性心律的患者中，分段法和实时法之间存在良好的一致性和相关性，实时序列的EDV只有轻微的、不显著的低估（135.95±30 mL vs. 137.15±31,p = 0.164）。在心律失常患者中，螺旋实时CMR比传统的分割成像产生更好的图像质量，允许与参考超声心动图容积法非常一致。相比之下，在该队列中，标准笛卡尔CMR显示LV-ESV显著低估（106.72±63.51 mL vs 125.47±72.41 mL, p = 0.026）和LVEF显著高估（42.96±10.81% vs 39.02±11.72%,p = 0.039）；(4)结论：实时螺旋CMR提高了心律失常患者的图像质量，可以可靠地评估左室容量。
(1) Background: Segmented Cartesian Cardiovascular magnetic resonance (CMR) often fails to deliver robust assessment of cardiac function in patients with arrhythmia. We aimed to assess the performance of a tiny golden-angle spiral real-time CMR sequence at 1.5 T for left-ventricular (LV) volumetry in patients with irregular heart rhythm; (2) Methods: We validated the real-time sequence against the standard breath-hold segmented Cartesian sequence in 32 patients, of whom 11 presented with arrhythmia. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) were assessed. In arrhythmic patients, real-time and standard Cartesian acquisitions were compared against a reference echocardiographic modality; (3) Results: In patients with sinus rhythm, good agreements and correlations were found between the segmented and real-time methods, with only minor, non-significant underestimation of EDV for the real-time sequence (135.95 ± 30 mL vs. 137.15 ± 31, p = 0.164). In patients with arrhythmia, spiral real-time CMR yielded superior image quality to the conventional segmented imaging, allowing for excellent agreement with the reference echocardiographic volumetry. In contrast, in this cohort, standard Cartesian CMR showed significant underestimation of LV-ESV (106.72 ± 63.51 mL vs. 125.47 ± 72.41 mL, p = 0.026) and overestimation of LVEF (42.96 ± 10.81% vs. 39.02 ± 11.72%, p = 0.039); (4) Conclusions: Real-time spiral CMR improves image quality in arrhythmic patients, allowing reliable assessment of LV volumetry.
