背景和目的：实时压缩传感影像（CSrt）为两个心室提供了可靠的定量，但可能会改变图像质量。本研究的目的是基于反向分割压缩传感2D电影序列（CSrg）评估图像质量和左（LV）和右心室（RV）体积、射血分数和质量定量的准确性。方法：纳入30例患者。每位患者接受参考逆行分段稳态自由进动影像序列（SSFPref）、实时CSrt影像和分段逆行原型CSrg序列提供相同的切片。对SSFPref和CSrg图像集进行功能参数量化和图像质量评定。对这三个序列的边缘清晰度进行了评估，这是边缘扩展函数的估计。结果：平均扫描时间：SSFPref = 485.4±83.3 (SD) s (95% CI: 454.3 ~ 516.5), CSrg = 58.3±15.1 (SD) s (95% CI: 53.7 ~ 64.2) （p < 0.0001）。CSrg主观图像质量评分（中位数：4，范围：2-4）高于CSrt提供的主观图像质量评分（中位数：3，范围：2-4，p = 0.0008），与SSFPref综合图像质量评分（中位数：4，范围：2-4，p = 0.31）无差异。CSrg提供的左室和右室功能参数与SSFPref相似（p < 0.05）。边缘清晰度显著优于CSrg(0.083±0.013 （SD）像素−1；95% CI: 0.078 ~ 0.087)比CSrt组(0.070±0.011 (SD) pixel−1；95% ci: 0.066-0.074；p = 0.0004)，与参考技术无差异(0.075±0.016 （SD）像素−1；95% ci: 0.069-0.081；P = 0.0516)。结论：CSrg cine在一分钟内提供准确的左室和右室功能参数定量，而不影响主客观图像质量。
Background and objective: Real-time compressed sensing cine (CSrt) provides reliable quantification for both ventricles but may alter image quality. The aim of this study was to assess image quality and the accuracy of left (LV) and right ventricular (RV) volumes, ejection fraction and mass quantifications based on a retrogated segmented compressed sensing 2D cine sequence (CSrg). Methods: Thirty patients were enrolled. Each patient underwent the reference retrogated segmented steady-state free precession cine sequence (SSFPref), the real-time CSrt cine and the segmented retrogated prototype CSrg sequence providing the same slices. Functional parameters quantification and image quality rating were performed on SSFPref and CSrg images sets. The edge sharpness, which is an estimate of the edge spread function, was assessed for the three sequences. Results: The mean scan time was: SSFPref = 485.4 ± 83.3 (SD) s (95% CI: 454.3–516.5) and CSrg = 58.3 ± 15.1 (SD) s (95% CI: 53.7–64.2) (p < 0.0001). CSrg subjective image quality score (median: 4; range: 2–4) was higher than the one provided by CSrt (median: 3; range: 2–4; p = 0.0008) and not different from SSFPref overall quality score (median: 4; range: 2–4; p = 0.31). CSrg provided similar LV and RV functional parameters to those assessed with SSFPref (p > 0.05). Edge sharpness was significantly better with CSrg (0.083 ± 0.013 (SD) pixel−1; 95% CI: 0.078–0.087) than with CSrt (0.070 ± 0.011 (SD) pixel−1; 95% CI: 0.066–0.074; p = 0.0004) and not different from the reference technique (0.075 ± 0.016 (SD) pixel−1; 95% CI: 0.069–0.081; p = 0.0516). Conclusions: CSrg cine provides in one minute an accurate quantification of LV and RV functional parameters without compromising subjective and objective image quality.
