双能CT (DECT) 精确地绘制隔膜静脉的地图,用于微创心脏手术. 70%的阶段是 mitra loop cerclage (MLC) 的最佳选择,而60%的阶段是 transcatheter 心脏内射频移除 (TIRA) 的最佳选择.
科学领域:
- 心血管成像 - 心血管成像
- 干预心脏病学 干预心脏病学
- 医学诊断 医学诊断 医学诊断
背景情况:
- 最少侵入性心脏手术需要精确的手术前评估.
- 创新的疗法,如 mitra loop cerclage (MLC) 和跨导管心脏内射频移除 (TIRA) 正在出现.
- 心脏CT扫描对于这些新的治疗方法的解剖指导至关重要.
研究的目的:
- 通过检查近道隔膜静脉 (ps) 来评估心脏周期,以检查MLC.
- 为了评估TIRA的距离隔膜静脉 (ds).
- 为了确定确定这些静脉的最佳心脏阶段.
主要方法:
- 40名患者接受了双源计算机断层扫描 (DSCT) 与双能CT (DECT).
- 扫描使用了iopamidol和盐水,覆盖了心脏的基础.
- 噪音优化的图像在整个心脏周期内以10%的间隔重建,以进行静脉评估.
主要成果:
- 接近隔膜静脉 (ps) 在62.5%的患者中被确定;远隔膜静脉 (ds) 在72.5%中.
- 这两种静脉在45%的病例中都存在.
- 确定了心脏相间ps和ds的最佳可视化序列.
结论:
- 双能量CT (DECT) 是有效的评估隔膜静脉频率在心脏成像.
- 70%的心脏阶段是确定MLC近端隔膜静脉 (ps) 的最佳状态.
- 60%的心脏阶段是首选的,用于识别TIRA的远隔膜静脉 (ds).

Imaging Studies for Cardiovascular System II:Types of Echocardiography
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
Imaging Studies for Cardiovascular System III: X-Ray
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...
Imaging Studies for Cardiovascular System I:Echocardiography
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
