概括

准确的胆道瘤边界映射对于管理至关重要. 包括OCT在内的多模式评估提高了准确性,特别是对于颜色较少的瘤,与标准色底摄影或单独的SLO相比.

科学领域:

眼科医生眼科眼科
医疗成像医学成像
在瘤学瘤学.

背景情况:

精确地绘制胸腔瘤边界对于有效的临床管理至关重要.
目前的方法通常依赖于单模评估,如彩色底部摄影 (CFP) 或扫描激光眼镜镜检查 (SLO).

研究的目的:

为了比较单模 (CFP或SLO) 和多模 (CFP,SLO和OCT) 评估之间的胆道瘤边界映射的准确性.
为了确定影响不同成像模式的性能的特定瘤特征.

主要方法:

一项横截面诊断准确性研究,涉及63名患者的64个胆道病变.
两位独立的眼科瘤学家在CFP和SLO上划出了病变边缘.
多模式评估是通过协议建立的,单模式和多模式评估之间的协议是使用第95百分位 Hausdorff 距离 (HD95) 量化.

主要成果:

总体而言,单模CFP和SLO与多模评估达成良好一致 (中位数HD95<1毫米).
然而,在5-9%的CFP和2-3%的SLO评估中出现了差异 (HD95>2mm).
无色素和混合色素瘤显示HD95显著更高,这表明在单模评估时边界确定不那么准确 (P <0.05).

结论:

使用CFP和SLO进行胆道瘤边缘评估通常与多式评估 (包括增强深度成像OCT (EDI-OCT)) 相比更准确.
减少色素的瘤的边界不准确地确定,仅使用 fundus 摄影.
将EDI-OCT纳入胸腔瘤边界映射可能会减少差异,特别是在具有挑战性的病例中.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
