概括

扩散张力成像 (DTI) 和扩散权重成像 (DWI) 并没有显著改善检测活跃肌肉炎炎炎症. 肌肉和MRI上的脂肪透得分更好地预测了他的病理学发现.

科学领域:

医疗成像医学成像
神经学神经学
类风湿病学类风湿病学

背景情况:

肌肉炎涉及肌肉炎症,可能会改变通过扩散张量成像 (DTI) 检测到的水扩散.
组织病理学检查是诊断肌肉炎和评估肌肉损伤的黄金标准.

研究的目的:

为了将广侧面肌 (VL) 的DTI发现与肌肉炎患者的组织病理学结果相关联.
评估MRI变量的诊断性能,以预测肌肉炎的组织病理结果.

主要方法:

43名肌炎患者接受了DWI/DTI协议的大腿MRI.
33名患者进行了VL肌肉活检以进行组织病理学分析.
磁力共振成像分析包括分级肌肉和脂肪透,并获取DWI/DTI参数.

主要成果:

平均DWIADC为1.77±0.35和DTIADC为2.06±0.35. 平均DWIADC为1.77±0.35和DTIADC为2.06±0.35. 平均DWIADC为1.77±0.35和DTIADC为2.06±0.35. 平均DWIADC为1.77±0.35和DTIADC为2.06±0.35.
平均FA为0.39±0.17;固有值为2.96±0.63,2.05±0.32和1.20±0.39. 这两项均为1.20±0.39.
最好的预测炎症的VL胀SI得分; 最好的预测缩的VL脂肪透得分.

结论:

DWI和DTI并没有显著增强肌肉炎中活性炎症的检测.
传统的MRI序列用于和脂肪透是有价值的预测他的病理学变化.

Myocarditis II: Clinical features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
