概括

来自CT扫描的放射性特征可以预测癌的结果. 在初始放射治疗后瘤纹理和形状的变化显示出风险分层的潜力.

科学领域:

放射学放射学是指放射学
在瘤学瘤学.
医疗成像医学成像

背景情况:

当地发达的不可切除的癌会带来治疗挑战.
预后生物标志物对于风险分层和个性化治疗至关重要.

研究的目的:

为了研究来自CT模拟扫描的三角放射性特征的预后价值.
评估这些特征在预测癌患者局部控制和整体存活率方面的潜力.

主要方法:

在21名患者的基线和I期后CT扫描中分析了107个放射性特征.
提取代表扫描之间变化的三角洲放射性特征.
应用一个多步特征选择管道 (Cox选,相关性过,Lasso-Cox).

主要成果:

一个单一的纹理三角形特征预测了局部控制 (p=0.039,C指数=0.748).
六个三角形特征预测了整体存活率 (C指数=0.864).
增加的纹理/形状复杂性与更差的生存率相关;增加的均性预测了更好的生存率.

结论:

基于CT的三角放射性特征,特别是纹理和形状指标,对预测无法切除的癌的局部控制和整体存活有希望.
德尔塔放射学可以作为风险分层的非侵入性生物标志物.
建议在更大的队列中进一步验证,并在适应性放射治疗中进行探索.

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...
