概括

磁共振成像 (MRI) 提供了一种定量方法来分阶段下肢淋巴 (LEL). 不对称体积测量,特别是皮下体积差 (DVS),与临床分期有很强的相关性,可以区分LEL的早期阶段.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
整形外科整形外科整形外科

背景情况:

目前下肢淋巴 (LEL) 的分期依赖于体检,缺乏定量成像评估.
对初级LEL的目标分期对于有效的管理和治疗规划至关重要.

研究的目的:

评估MRI衍生不对称体积测量的实用性,用于初级LEL的临床分期.
为了确定定量MRI指标是否与临床分期比传统方法更好地相关.

主要方法:

92名单边初级LEL患者接受了MRI扫描.
使用MRI测量小牛体积 (总体,肌肉骨,皮下).
计算了受影响和不受影响的四肢之间的不对称体积差异 (例如,DVS).
评估了与临床阶段和诊断准确度 (ROC曲线) 的相关性.

主要成果:

不对称的体积差异显示了LEL阶段的统计学上显著的变化.
基于MRI的不对称体积差异 (DVmri,DVS) 与临床阶段的相关性比其他体积测量更强.
皮下体积差 (DVS) 在区分I阶段和II阶段LEL方面表现出最高的准确性 (AUC=0.951).

结论:

基于MRI的不对称体积差异是LEL临床分期的可复制,辅助工具.
皮下体积差异 (DVS) 是区分初级LEL早期阶段的有希望的指标.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
