概括

这项研究使用两种血管造影系统比较前列腺动脉栓塞 (PAE) 期间的辐射暴露. 与AS1相比,AS2系统显著降低了辐射剂量,并增加了形束计算断层扫描 (CBCT) 的利用率.

科学领域:

干预性放射学干预性放射学
医疗成像医学成像
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

前列腺动脉栓塞 (PAE) 是一种治疗良性前列腺增生的方法.
在PAE程序中,暴露于辐射是令人担忧的.
圆束计算断层扫描 (CBCT) 可以帮助PAE,但可能会增加辐射剂量.

研究的目的:

为了比较形束计算断层扫描 (CBCT) 的利用率和在两个不同的血管学系统上进行的PAE手术期间的辐射暴露.
评估血管造影系统选择对辐射指标和PAE中CBCT使用的影响.

主要方法:

在两种血管学系统 (AS1和AS2) 上,由单个干预专家进行的PAE手术的回顾性分析.
评估CBCT获取率,光镜时间,DSA系列,CBCT每例,以及辐射指标 (空气克尔玛,克尔玛面积产物).
两种系统之间的数据的统计比较,对体重指数进行调整.

主要成果:

与AS1 (31%) 相比,AS2 (85%) 的CBCT利用率显著更高.
每个CBCT的平均总克尔马面积产物和空气克尔马在AS2中明显低于AS1.
光镜时间和平均前列腺体积在两个系统之间是相似的.

结论:

血管造影系统显著影响PAE期间的CBCT利用率和辐射暴露.
与AS1相比,AS2系统显示患者和工作人员的辐射暴露较低.
优化血管造影系统选择可以提高PAE程序的安全性和效率.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (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

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...
