CNS applications of advanced MR imaging techniques
| Technique | Application |
|---|---|
| DTI and fiber tractography12,13 | Biopsy guidance |
| Determination of functionally eloquent tracts and surgical plan | |
| PWI14–24 | |
| DSC | Differential diagnosis: tumor vs nontumoral lesions, primary vs metastatic lesions, tumor grading, tumor complications, treatment response, pseudoprogression |
| DCE | Differential diagnosis: tumor vs nontumoral tissue, tumor grading, treatment response, pseudoprogression |
| DWI25,26 | Differential diagnosis: tumor vs nontumoral lesions, tumor grading, treatment response |
| ADC27,28 | Glioma grading, differentiation of high cellularity lymphoma |
| MRS29–33 | Differential diagnosis: tumor vs nontumoral lesions, primary vs metastatic lesions, treatment response |
| Blood oxygen level–dependent imaging34 | Neuronal activity, surgical guidance |
| Nuclear medicine, PET35 | Biopsy guidance, treatment response, differential diagnosis: tumor recurrence vs radionecrosis |
| Volumetric imaging36 | Not widely available and implementable |
