概括

与5.0 T MRI的人工智能 (AI) 辅助压缩传感 (ACS) 与平行成像 (PI) 相比,显著改善肝损伤图像质量. 这种先进的技术在不增加扫描时间的情况下提供了可比的病变检测率,从而提高了诊断能力.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
人工智能的人工智能

背景情况:

肝脏瘤病变通常使用1.5T或3.0TMRI进行评估.
超高场5.0 T MRI显示肝损伤评估报告有限.
这项研究研究了人工智能辅助的压缩传感 (ACS) 在5.0 T的肝损伤成像.

研究的目的:

通过使用AI-ACS在5.0TMRI的5.0TMRI,对肝损伤显示和图像质量进行定量和质量分析.
将AI-ACS与传统并行成像 (PI) 技术进行比较.
为了比较肝胆相 (HBP) 图像的病变检测率和图像质量,使用PI和ACS在5.0 T.

主要方法:

133名疑似肝脏瘤的患者接受了5.0 T Gd-EOB-DTPA增强型MRI.
扫描包括在HBP期间使用PI和ACS的轴向和冠状3D快速破坏的梯度回声序.
使用客观 (SNR,CNR,对比率,清晰度) 和主观 (工件,边缘清晰度,整体质量) 评分来评估图像质量.

主要成果:

PI和ACS的扫描时间相似 (17对18秒).
与PI-quick-3D相比,ACS-quick-3D显示出更高的客观和主观图像质量得分 (P<0.001),除了图像文物.
损伤检测率在ACS和PI之间是可比的 (98.71%与99.14%>10毫米;95.03%与98.34%≤10毫米),ACS在检测肝囊下亚厘米损伤方面表现出色.

结论:

使用ACS-quick-3D在5.0 T的Gd-EOB-DTPA增强型MRI显著提高了图像质量.
在ACS和PI之间,损伤检测率仍然相当.
ACS-quick-3D可在5.0T时进行增强的肝病变成像,而不会增加检查时间.

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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...
