医疗成像医学成像
在瘤学瘤学.

背景情况:

肺部瘤需要准确的诊断方法.
目前的诊断方法可能具有侵入性.
量化组织硬度估计是肺部成像的一个新兴领域.

研究的目的:

评估基于Intravoxel不连贯运动 (IVIM) 的虚拟磁共振弹性图形 (vMRE) 的可行性,以量化肺瘤硬度.
为了评估转移的明显扩散系数 (sADC) 和虚拟刚性的诊断性能,以区分瘤性质.

主要方法:

59名肺部瘤患者在活检前接受了IVIM MRI.
重建了转移的表面扩散系数 (sADC) 和虚拟剪切刚度图.

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
