Assessment of biological properties by MR and PET
| MR | PET |
|---|---|
| Morphology | Flow (H2 15O) |
| Water diffusion capacity (DWI) | Metabolism (18F-FDG) |
| Vascular anatomy (MRA) | Blood volume (C15O) |
| Perfusion (PWI, DCE-MRI) | Oxygen consumption (15O) |
| Tissue metabolites (MRS) | Hypoxia (18F-MISO) |
| Functional activation (fMRI) | Vascular permeability (labeled AA) |
| Cerebral fiber tracts (DTI) | Nuclide acid synthesis (18F-FLT) |
| Oxygen consumption (17O) | Transmitters (e.g., 18F-DOPA) |
| Migration of cells (Fe labeling) | Receptors (e.g., raclopride) |
| Enzymatic activity (e.g., MP4A) | |
| Angiogenesis (e.g., 18F-RGD) | |
| Distribution and kinetics of tracers and drugs (labeled compounds) | |
| Enzymatic activity in transfected cells |
