概括
在健康的眼睛中,瞳孔膨胀或瞳孔膨胀不会显著改变黄斑或周膜视网膜血管密度. 然而,脑膜炎可以降低胸膜厚度,并在某些斑点和周围斑块部门增加视网膜厚度.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 视网膜成像 视网膜成像
背景情况:
- 准确的视网膜成像对于诊断和监测眼睛疾病至关重要.
- 瞳孔扩张 (心水病) 通常用于改善 fundus 检查期间的可视化.
- 肌病对从扫描源光学连贯性断层扫描血管学 (SS-OCTA) 获得的定量指标的影响需要进行彻底的调查.
研究的目的:
- 为了评估肌病对通过SS-OCTA在健康受试者中获得的斑点和周围斑点指标的影响.
- 为了确定瞳孔膨胀是否会影响关键的视网膜和胸膜测量.
主要方法:
- 三十五名健康人接受了SS-OCTA扫描的斑点 (3x3mm和6x6mm模式) 和 peripapillary区域 (4.5x4.5mm模式) 之前和之后mydriasis.
- 测量了斑点和周围斑点指标,包括视网膜血管密度 (VD) 和 fundus 厚度.
- 分析了右眼的数据.
主要成果:
- 信号强度在肌病之前和之后保持相似 (P>0.05).
- 在骨无血管区 (FAZ) 参数和大多数视网膜VD部门 (P>0.05) 中没有发现显著差异.
- 脑膜炎导致大脑胆膜厚度下降,在大多数黄斑部门的外侧/整个视网膜厚度增加 (P<0.05).
- 周 papillary 冠状腺厚度下降,而一些整个视网膜和 GCC 厚度增加 (P<0.05).
结论:
- 在大多数黄斑和外皮皮质区域中,水症不会显著影响FAZ参数或视网膜VD.
- 脑膜炎会导致冠状腺厚度的降低.
- 视网膜层在特定的黄斑和周围毛囊部门的厚度可能会增加后水症.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
