其次，利用 3.0 - T MRI 扫描仪获取 T2 加权图像（T2WI），由放射科医生手动分割感兴趣区域（VOI），并使用 PyRadiomics 软件包提取 1781 个影像组学特征。 然后，运用树状管道优化工具（TPOT）算法，通过 5 折交叉验证构建诊断模型，并使用 Shapley Additive exPlanations（SHAP）值评估特征对模型的影响 。

为探索横纹肌肉瘤诊断新途径，研究人员利用 T2 加权 MRI 影像组学及模型，发现其预测价值，意义重大。 横纹肌肉瘤（Rhabdomyosarcomas）是儿童中最常见的软组织肉瘤。尽管治疗效果有所改善，但基于风险的治疗分类仍依赖于分期 ...

MRI performed 120 min after his fall showed spinal canal stenosis due to disk protrusion at the C3/4 level without spinal cord signal changes on T1- and T2-weighted images. He underwent ...

MRI IMAGING SEQUENCES. The most common MRI sequences are T1-weighted and T2-weighted scans. T1-weighted images are produced by using short TE and TR times. The contrast and brightness of the image are ...

T2-weighted MRI. T2-weighted MRI is useful in the local staging of cancer and treatment planning in intermediate- and high-risk patients. It has good sensitivity rate for prostate cancer detection.

Can index lesion tumor volume on T2 weighted MRI predict biochemical recurrence following radical prostatectomy?. JCO 35 , 32-32 (2017). DOI: 10.1200/JCO.2017.35.6_suppl.32 ...

This study was carried out to assess the role of statistical and fractal heterogeneity parameters from pre-treatment and early post-CRT T2- and diffusion-weighted MR in predicting disease outcome.

Areas of abnormal white matter in the brains of multiple sclerosis (MS) patients appear much larger on diffusion tensor MRI than on T2-weighted MRI, a finding which could impact therapy options ...

Pre-treatment T2-weighted MRI texture features can predict NAC response with reasonable accuracy. Locally advanced breast cancer (LABC) is defined as breast cancer with tumors greater than 5 cm, ...

The team used a clinical MRI scanner, of the type all neuroscience centers have, to carry out a special type of scan called a T2*-weighted MRI which is able to reveal lesions in the brain's white ...
