Table 2 Summary of the MRI neuroimaging portfolio
MRI imaging sequences | Diagnostic target |
|---|---|
T1, T2, proton density signal weighting | Ischemic or hemorrhagic brain lesions. |
Structural brain abnormalities (hydrocephalus, neurodevelopmental disorders, brain tumors). | |
Magnetization-prepared rapid acquisition gradient-echo (three-dimensional) | Structural brain abnormalities. |
Anatomical three-dimensional template for subsequent rs-fMRI coregistration. | |
Fluid attenuated inversion recovery | Ischemic lesion of the brain parenchyma (acute, subacute, and chronic). |
Diffusion-weighted imaging | Discrimination between acute, subacute, and chronic ischemic lesions, based on reduced diffusibility in acute or subacute lesions presenting as high signal on diffusion-weighted imaging sequence and low signal on calculated apparent diffusion coefficient maps. |
rs-fMRI | Functional brain connectivity within neural networks. Comparison of functional connectivity patterns before and after operation. |
