概括

这项研究表明,计算机断层扫描 (CT) 的定量参数可以区分上腺脂质贫乏腺瘤和结节性增生. 与放射科医生相比,CT模型整合了门静脉相衰减,体积比率和病变数量,显示出更高的诊断性能.

科学领域:

放射学放射学是一门学科.
在瘤学瘤学.
内分泌学在内分泌学.

背景情况:

上腺病变需要准确的分化,以进行适当的管理.
缺乏脂质的腺瘤 (LPA) 和结节性增生可以呈现类似的成像特征.
区分这些实体至关重要,以避免不必要的干预.

研究的目的:

评估CT定量参数的诊断性能,以区分上腺LPA与结节性增生.
开发和评估基于CT的模型,以提高诊断准确度.

主要方法:

对128名患有LPA或结节性增生症的患者进行了回顾性分析.
测量了包括未增强衰减,门静脉相衰减 (CTp) 和体积比率在内的定量CT参数.
使用后勤回归和ROC曲线分析来开发诊断模型.
模型的性能与放射科医生的主观评估进行了比较.

主要成果:

门静脉相衰减,体积比和病变数量是LPA的独立预测因素.
开发的CT模型实现了0.835的AUC,敏感度为73.5%,特异性为80.0%.
与放射科医生相比,CT模型显示出优越的诊断性能和可重现性.

结论:

门静脉阶段CT定量参数在区分上腺LPA和结节性增生症方面表现有前途.
结合CTp,体积比和病变数量的CT模型提供了比主观放射科医生的解释更好的诊断准确性和可重复性.

Brain Abscess l: Introduction

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
