动脉旋转标记 (ASL) 在区分高度质瘤进展与治疗后六个月内治疗效果的准确性有限. 它的诊断价值随着时间的推移而提高,但可能需要与其他临床数据进行整合以获得更好的准确性.
科学领域:
- 神经瘤学神经瘤学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 在放射治疗后的高度质瘤中,区分治疗诱导的影响与进展性疾病是具有挑战性的.
- 动脉自旋标记 (ASL) perfusion 成像是一种非侵入性技术,用于质瘤的随访.
研究的目的:
- 评估ASL的诊断性能,以区分放射性高度质瘤中进展性疾病与治疗诱导的影响.
- 评估放射治疗后时间对ASL诊断准确性的影响.
主要方法:
- 对141名患有高度质瘤的患者进行了回顾性队列研究.
- 视觉和定量分析了ASL输液成像.
- 根据组织学或>6周的随访,病变被归类为进展性疾病或治疗诱导的影响.
主要成果:
- 在辐射后6个月内,ASL在分化进展方面表现不佳 (AUC 0.456-0.520).
- 6个月后,诊断性能得到改善 (视觉AUC为0.719).
- 视觉ASL分级的inter-和intrarater可靠性是公平的 (κ=0.67和0.62).
结论:
- 在放射治疗后6个月内,ASL在区分进展性疾病与高度质瘤的治疗效果方面具有有限的效用.
- 在6个月以后,ASL的表现会有所改善,但可能需要与其他成像和临床数据相结合,以提高诊断准确度.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
