概括

内静脉圆束计算机断层扫描 (CBCT A/V) 大脑是安全有效的成像工具,用于立体电脑图 (SEEG) 规划. CBCT A/V发现的电极血管冲突 (EVC) 比MRI更多,包括与内出血 (ICH) 相关的.

科学领域:

神经外科神经外科
医疗成像医学成像
发病学 (Epileptology) 是一个专业的学科.

背景情况:

立体电脑图 (SEEG) 需要精确的电极放置,以定位耐性的发性区域.
术前成像 (MRI,DSA,CT) 旨在通过识别电极-血管冲突 (EVC) 来预防内出血 (ICH).
数字减去血管学 (DSA) 提供了高分辨率,但也带来了风险,促使人们探索诸如静脉圆束计算机断层扫描 (CBCT A/V) 等替代方法.

研究的目的:

为了验证CBCT A/V Brain用于SEEG规划的安全性和有效性.
将CBCT A/V检测EVC的能力与传统成像方式进行比较.
调查冲突船口径与SEEG期间ICH发生率之间的关系.

主要方法:

一项对20名接受SEEG,手术前CBCT A/V和MRI脑部MRI治疗的患者的回顾性研究.
对273个电极植入的分析,记录症状和无症状ICH的发生率和程度.
通过CBCT A/V和MRI发现的EVC和冲突血管直径的量化.

主要成果:

在273个电极上发生了4个ICH事件 (2有症状,2无症状).
在CBCT A/V检测中,发现的EVC (20) 比MRI (6) 显著多 (P < 0.0001).
两个有症状的ICH与EVC (平均直径1.5毫米) 相关,通过CBCT A/V检测到,但不是MRI.

结论:

CBCT A/V 大脑证明了SEEG规划的可接受的安全概况.
在检测EVC方面,CBCT A/V显著优于MRI,包括与ICH相关的EVC.
在CBCT A/V上的冲突容器<1.2毫米口径在这个SEEG系列中与ICH没有相关.

关键词:

Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
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 VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
