在这个人群中,脑内创伤异常 (tICA) 的诊断中,脑内计算机断层扫描 (cCT) 经常被过度使用.
为tICA开发准确的预测工具对于优化老年患者的诊断成像至关重要.

研究的目的:

开发和验证用于预测老年患者 (≥60岁) 的tICA的诺米克图.
提高诊断准确度,并可能减少老年人群中不必要的cCT扫描.

主要方法:

一项回顾性队列研究,涉及2362名接受第三级转诊医院治疗的老年患者.
数据分为开发队列 (2015-2019) 用于创建名ogram 和验证队列 (2020-2022) 用于时间验证.
二元逻辑回归被用来识别预测因素并构建名ogram.

主要成果:

多变量分析确定了阿司匹林/华法林使用,交通事故,格拉斯哥昏迷表得分 (9-12),记忆丧失,恶心/吐,发作,运动疲弱和鼻子/耳朵出血是tICA的重要预测因素.
开发的名图表显示了高预测性能,接收器操作特征曲线下的面积为0.889.
在预测TICA时,该名录实现了0.833的灵敏度和0.788的特异性.

结论:

Traumatic Brain Injury l: Introduction

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.
