概括
表面扩散系数 (ADC) 组图分析,特别是斜度和形,可以从 schwannomas 区分 parapharyngeal 形腺瘤. 平均ADC值在这些瘤类型之间没有显著差异.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 副喉空间瘤带来了诊断方面的挑战.
- 在治疗规划中,区分多形腺瘤和形腺瘤至关重要.
研究的目的:
- 调查表面扩散系数 (ADC) 历史图分析在区分副喉多形腺瘤与 schwannomas 的实用性.
- 用扩散权重核磁共振 (MRI) 来比较这两种瘤类型之间的ADC值的组图度量.
主要方法:
- 追溯分析了29个形腺瘤和22个副腔空间的形腺瘤.
- 从手术前的MRI中测量ADC值和组织图度量 (平均值,斜率,曲率).
- 使用Wilcoxon的等级总和测试进行统计比较,包括基于b值和磁场强度的子组分析.
主要成果:
- 平均ADC值显示 pleomorphic腺瘤和 schwannomas 之间没有显著差异.
- 在ADC组图中,与形腺瘤相比,斯万诺瘤的斜度显著更高 (p=0.0001) 和曲化率更低 (p=0.003).
- 在所有子组分析中,在 schwannomas 中,度仍然显著更高.
结论:
- ADC 基因组图的斜率和形是区分副喉多形腺瘤和 schwannomas 的有价值的参数.
- 单独的平均ADC值不足以区分这些副喉瘤.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...
