摘要
目的：探讨联合成像压缩感知与径向采集（uCSR）在老年恶性肿瘤患者肝脏动态增强检查中的应用价值。方法：将100例65岁及以上的患者随机分为两组：50例患者在自由呼吸时使用uCSR序列进行肝脏动态对比增强扫描，50例患者在屏气时使用三维体积内插屏气检查（3D-VIBE）序列进行扫描。两名放射科医生独立和主观地用五分制评估整体图像质量和图像伪影。同时，两名技术人员测量了两组动脉、门静脉和延迟期图像的信噪比（SNR）和噪声对比比（CNR）。结果：uCSR具有较好的整体图像质量和图像伪影评分(z = 2.342, p = 0.019；Z = 2.105, p = 0.035)。动脉期3D-VIBE图像的信噪比高于uCSR (t = 4.988, p = 0.000)，而CNR差异无统计学意义（z = 0.676, p = 0.499）。门静脉期，3D-VIBE图像的信噪比和CNR优于uCSR (z = 5.674, p = 0.000；T = 3.638, p = 0.000)。在延迟阶段，3D-VIBE的信噪比略好于uCSR (t = 5.471, p = 0.000)，而CNR无显著差异（z = 1.258, p = 0.208）。结论：uCSR可作为老年恶性肿瘤患者肝脏动态增强扫描的一种方法。提高患者舒适度，降低扫描失败率。关键相关性声明：我们的研究结果提示uCSR可用于老年恶性肿瘤患者的肝脏动态对比增强扫描，本初步研究为其提供了依据。重点：uCSR可以抑制呼吸运动伪影对图像的影响。UCSR可以在自由呼吸动力下对肝脏进行动态增强扫描。uCSR适用于老年恶性肿瘤患者肝脏动态增强磁共振成像。
Preliminary study on the feasibility of united compressed sensing with radial acquisition as a routine method for liver dynamic contrast-enhanced examination in elderly patients with malignancy.
Objective: To explore the value of the united imaging compressed sensing with radial acquisition (uCSR) in liver dynamic contrast-enhanced examinations for elderly patients with malignancy.
Methods: Hundred patients aged 65 years or over were randomly divided into two groups: 50 patients underwent liver dynamic contrast-enhanced scanning using the uCSR sequence during free breathing, and 50 patients underwent scanning using the three-dimensional volume interpolated breath-hold examination (3D-VIBE) sequence while holding breath. Two radiologists independently and subjectively evaluated the overall image quality and image artifacts with a five-point scale. Concurrently, two technologists measured the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the arterial, portal venous and delay phase images in both groups.
Results: uCSR has superior overall image-quality and image-artifact scores (z = 2.342, p = 0.019; z = 2.105, p = 0.035). The 3D-VIBE images of the arterial phase have higher SNR than uCSR (t = 4.988, p = 0.000), with no significant difference in the CNR (z = 0.676, p = 0.499). In the portal venous phase, the SNR and CNR of the 3D-VIBE images are superior to those of uCSR (z = 5.674, p = 0.000; t = 3.638, p = 0.000). In the delay phase, the SNR of the 3D-VIBE is slightly better than the uCSR (t = 5.471, p = 0.000), and the CNR shows no significant difference (z = 1.258, p = 0.208).
Conclusion: uCSR can be used as a method for liver dynamic contrast-enhanced scans in elderly patients with malignancy. It can improve patient comfort and reduce the failure rate of scans.
Critical relevance statement: Our findings suggested that uCSR can be used for liver dynamic contrast-enhanced scans in elderly patients with malignancy, this preliminary study provided basis for it.
Key points: The uCSR can suppress the impact of respiratory motion artifacts on images. The UCSR can perform dynamic enhanced scanning of the liver under free breathing dynamics. The uCSR is suitable for dynamic contrast-enhanced MR imaging of the liver in elderly patients with malignancy.
