概括
扩散曲解成像 (DKI) 和扩散张力成像 (DTI) 能够有效地检测结质瘤患者的皮质脊髓管 (CST) 异常. 结合DKI和DTI显示出高的诊断性能来评估CST损伤和运动功能缺陷.
科学领域:
- 神经成像是一种神经成像.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 质瘤可能会影响皮质脊髓管 (CST),导致运动缺陷.
- 准确评估CST完整性对于预测患者结果至关重要.
研究的目的:
- 评估扩散曲解成像 (DKI) 和扩散张力成像 (DTI) 在识别CST异常的诊断性能.
- 为了在质瘤患者中将CST异常与运动功能相关联.
主要方法:
- 分析了21名患有世卫组织II级或IV级质瘤的患者.
- 创建了DKI和DTI指标,并将其投射到CST.
- 用直方图和ROC曲线来评估诊断疗效.
主要成果:

01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
