Abstract

Purpose

The purpose of this study was to compare a new free-breathing compressed sensing cine (FB-CS) cardiac magnetic resonance imaging (CMR) to the standard reference multi-breath-hold segmented cine (BH-SEG) CMR in an unselected population.

Materials and methods

From January to April 2021, 52 consecutive adult patients who underwent both conventional BH-SEG CMR and new FB-CS CMR with fully automated respiratory motion correction were retrospectively enrolled. There were 29 men and 23 women with a mean age of 57.7 ± 18.9 (standard deviation [SD]) years (age range: 19.0–90.0 years) and a mean cardiac rate of 74.6 ± 17.9 (SD) bpm. For each patient, short-axis stacks were acquired with similar parameters providing a spatial resolution of 1.8 × 1.8 × 8.0 mm³ and 25 cardiac frames. Acquisition and reconstruction times, image quality (Likert scale from 1 to 4), left and right ventricular volumes and ejection fractions, left ventricular mass, and global circumferential strain were assessed for each sequence.

Results

FB-CS CMR acquisition time was significantly shorter (123.8 ± 28.4 [SD] s vs. 267.2 ± 39.3 [SD] s for BH-SEG CMR; P < 0.0001) at the penalty of a longer reconstruction time (271.4 ± 68.7 [SD] s vs. 9.9 ± 2.1 [SD] s for BH-SEG CMR; P < 0.0001). In patients without arrhythmia or dyspnea, FB-CS CMR provided subjective image quality that was not different from that of BH-SEG CMR (P = 0.13). FB-CS CMR improved image quality in patients with arrhythmia (n = 18; P = 0.002) or dyspnea (n = 7; P = 0.02), and the edge sharpness was improved at end-systole and end-diastole (P = 0.0001). No differences were observed between the two techniques in ventricular volumes and ejection fractions, left ventricular mass or global circumferential strain in patients in sinus rhythm or with cardiac arrhythmia.

Conclusion

This new FB-CS CMR addresses respiratory motion and arrhythmia-related artifacts without compromising the reliability of ventricular functional assessment.

一种新的压缩传感电影心脏MRI序列，具有自由呼吸实时采集和全自动运动校正:综合评估

目的本研究的目的是比较一种新的自由呼吸压缩传感电影(FB-CS)心脏磁共振成像(CMR)与标准参考的多屏气分段电影(BH-SEG) CMR在非选择人群中的应用。材料和方法从2021年1月至4月，回顾性纳入了52例连续接受传统BH-SEG CMR和新型FB-CS CMR并进行全自动呼吸运动校正的成人患者。男性29例，女性23例，平均年龄57.7±18.9(标准差[SD])岁(年龄范围:19.0 ~ 90.0岁)，平均心率74.6±17.9 (SD) bpm。对于每个患者，获得具有相似参数的短轴堆栈，提供1.8 × 1.8 × 8.0 mm3和25个心脏帧的空间分辨率。对每个序列的采集和重建时间、图像质量(李克特评分从1到4)、左右心室体积和射血分数、左心室质量和整体周向应变进行评估。结果fb - cs CMR采集时间明显短于BH-SEG CMR(123.8±28.4 [SD] s)， hb - seg CMR为267.2±39.3 [SD] s;P & lt;0.0001)，以较长的重建时间为代价(271.4±68.7 [SD] s vs. BH-SEG CMR为9.9±2.1 [SD] s;P & lt;0.0001)。在没有心律失常或呼吸困难的患者中，FB-CS CMR提供的主观图像质量与BH-SEG CMR没有差异(P = 0.13)。FB-CS CMR改善心律失常患者图像质量(n = 18;P = 0.002)或呼吸困难(n = 7;P = 0.02)，收缩期末和舒张期末边缘锐度均有提高(P = 0.0001)。两种方法在窦性心律或心律失常患者的心室容积和射血分数、左心室质量或总周应变方面没有差异。结论:这种新的FB-CS CMR在不影响心室功能评估可靠性的情况下解决了呼吸运动和心律失常相关的伪影。
