概括
腹部对比MRI可以识别自身免疫性肝炎 (AIH) 严重程度的特征,并预测治疗反应. 将MRI与血清模型相结合,可以提高AIH患者的诊断和预后准确性.
科学领域:
- 放射学和医学成像学 医学成像学
- 肝病学 肝病学是一种肝病学.
- 免疫学 免疫学 免疫学
背景情况:
- 自身免疫性肝炎 (AIH) 是一种慢性肝病,需要对严重程度和治疗反应进行准确的评估.
- 目前评估AIH严重程度和治疗反应的方法通常依赖于侵入性肝脏活检和实验室测试.
- 像腹部对比MRI这样的非侵入性成像技术显示出改善AIH评估的潜力.
研究的目的:

01:17Gastritis-II: Pathophysiology
163
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

206
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
