概括

扩散张力成像 (DTI) 揭示了中枢神经系统 (CNS) 结核病中的微观结构性白质变化. 在中枢神经系统结核病患者中减少的微分异型性 (FA) 与疾病严重程度相关,有助于预后.

科学领域:

神经学神经学
放射学放射学是指放射学
传染性疾病传染性疾病

背景情况:

中枢神经系统 (CNS) 结核病是一个重大挑战,特别是在像印度这样的高负担地区.
它与高发病率和死亡率有关.
了解微观结构白质变化对于有效管理至关重要.

研究的目的:

研究扩散张力成像 (DTI) 在评估中枢神经系统结核病中白质微观结构变化的作用.
为了将成像发现与疾病严重程度和潜在的临床结果相关联.

主要方法:

在两年内进行了一项横截面的观察性研究.
患有确定的或极有可能患有结核性脑膜炎的患者与健康对照人群进行了比较.

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
