心脏计算机断层扫描 (CT) 显示出与心脏磁共振 (CMR) 相比,对量化细胞外体积 (ECV) 有很好的相关性. 双能CT (DECT) 在ECV评估中提供了比单能CT (SECT) 更高的相关性.
科学领域:
- 心血管成像 - 心血管成像
- 放射学 放射学是一门学科.
- 医学物理 医学物理
背景情况:
- 细胞外体积 (ECV) 量化了细胞外空间的扩张,增加的ECV表明心肌纤维化.
- 心脏磁共振 (CMR) 是ECV量化的黄金标准,但心脏计算机断层扫描 (CT) 也被使用.
- 这一元分析比较了CT和CMR之间的ECV量化准确性.
结论:
- CT衍生的ECV与CMR衍生的ECV有很好的相关性,平均差异小于1%.
- 与SECT相比,DECT在ECV量化方面显示出更高的相关性.
- 需要进一步进行高质量的前性研究,以验证CT衍生的ECV的诊断和预后效用.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
