概括

轮回转回声扩散加权成像 (TSE-DWI) 比回声平面成像 (EPI-DWI) 显示的扭曲和工件较少. 放射科医生更喜欢TSE-DWI用于脑瘤手术中的手术内MRI (IoMRI).

科学领域:

神经辐射学神经辐射学
医疗成像医学成像
神经外科神经外科

背景情况:

术内核磁共振 (IoMRI) 使用扩散加权成像 (DWI) 进行脑瘤手术.
传统的回声平面成像DWI (EPI-DWI) 患有扭曲和工件影响图像质量.
轮旋转回声DWI (TSE-DWI) 提供了减少的空间扭曲,可能成为首选的序列.

研究的目的:

为了比较EPI-DWI和TSE-DWI,使用IoMRI设置中的单次和多次序评估.
为了确定放射科医生在EPI-DWI和TSE-DWI之间进行内瘤手术的偏好.

主要方法:

对34名接受内瘤IoMRI治疗的患者进行了回顾性研究.
由失明的神经放射学家进行的单次和多次序评估,比较EPI-DWI和TSE-DWI.
扭曲,文物,解剖学和异常的评分,记录了总体偏好.

主要成果:

在单个序列评估中,TSE-DWI在扭曲和工件方面始终获得与EPI-DWI相等或高于EPI-DWI的分数.
在多序评估中,所有放射科医生都更喜欢TSE-DWI而不是EPI-DWI来评估大脑解剖学,异常和人工物.

结论:

与IoMRI用于脑瘤病例的EPI-DWI相比,TSE-DWI序列显示出更高的性能.
在用于内瘤的手术内MRI的背景下,TSE-DWI可能比EPI-DWI更受青.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
