MRI provides high soft tissue contrast and is able to detect edema, a potential marker of inflammatory stages in FOP.(9–12) MRI is currently used in FOP to evaluate the presence of edema early in flare-ups. (10) Whether the two stages of FOP, active flareups and asymptomatic ...
An MRI scan of the right knee with and without contrast was performed. In order: T1-weighted and short tau inversion-recovery (STIR) images and 'water lava flex' pre- and postcontrast images. 行右膝MRI平扫+增强扫描。分别为:T1WI、T2-STIR、平扫+增强图像。
Dynamic Contrast-Enhanced MRI Dynamic contrast-enhanced MRI(DCE-MRI) is T1-weighted imaging that is acquired dynamically over several minutes with a high temporal resolution during intravenous injection of a volume of gadolinium-diethylene triamine pentaacetic acid (Gd-DTPA). It is capable of measuring...
Results 结果 The segmentation technique was validated with a clinical study of 49 patients by leave-one out experiments and validated with an additional 50 patients by hold-out test. The Dice similarity coefficient, Hausdorff distance, and mean surface distance indices between our segmented and deform...
Top of pageTHEORETICAL BACKGROUND EXPERIMENTAL RESULTS AND DISCUSSION CONCLUSIONS REFERENCES A new MRI method with a contrast that is derived from the macromolecular composition and spin dynamics in the tissue is described and demonstrated on excised mouse brain and rat spinal cord. In the method, ...
动态对比增强磁共振成像(dynamic contrast-enhanced magnetic resonance imaging,DCE-MRI)是乳腺MRI最灵敏的成像序列,该技术的原理是通过连续、快速地扫描获取对比剂注射前后多个时间点的图像。在以往研究中,NAC评估常用的MRI特征有肿瘤直径、体积和病灶增强...
