概括
功能性排泄肝体积 (fDLV) 的客观评估准确地预测皮肤透肝胆道排水 (PTBD) 后的临床成功,优于主观评估. 这种客观测量有助于预测患有恶性胆道阻塞的PTBD后患者的结果.
科学领域:
- 干预性放射学 干预性放射学
- 肝胆道成像 肝胆道成像
- 在瘤学瘤学.
背景情况:
- 皮肤通过肝胆道排水 (PTBD) 是对恶性胆道阻塞的关键干预措施.
- 准确预测PTBD后的临床成功对于患者管理至关重要.
- 功能性排出肝体积 (fDLV) 是结果的潜在预测指标,但其评估方法各不相同.
研究的目的:
- 为了比较主观与客观评估的预测准确度,对PTBD后临床成功的三维功能性排出肝体积 (fDLV) 的预测准确度.
- 在患有恶性胆道阻塞和高胆血的患者中评估客观fDLV测量的可靠性.
主要方法:
- 对35名因恶性胆道阻塞而接受新的PTBD患者的回顾性研究.
- 主观fDLV由放射科医生分类;客观fDLV使用成像软件计算.
- 临床成功定义为30天内总 bilirubin < 1.8 mg/dL.
- 使用ICC评估观察者间协议;使用后勤回归和ROC曲线分析预测准确性.
主要成果:
- 目标fDLV (体积,百分比,类别) 与临床成功有显著的相关性 (P < .005).
- 主观的fDLV评估显示观察者之间的一致性很低 (ICC = 0.29),并且与成功没有显著的关联 (P = .081).
- 与主观估计 (AUC范围=0.560.74) 相比,目标fDLV百分比显示出更高的预测准确性 (AUC=0.84).
结论:
- 对fDLV的客观评估比主观评估更准确地预测PTBD后的短期临床成功.
- 客观的fDLV测量,特别是百分比,为患有恶性胆道阻塞的患者提供可靠的预后信息.
- 这些发现支持客观fDLV计算在治疗PTBD患者的日常使用.

Imaging 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...
