Study Notes
Classification of Imaging Modalities
Anatomical Imaging
- X-rays are used for basic imaging of bones and certain soft tissues.
- CT scans provide detailed cross-sectional anatomical information.
- MRI produces high-contrast images of soft tissues using magnetic fields.
Functional Imaging
- PET scans show metabolic processes occurring in the body.
- SPECT scans are similar to PET scans but use different tracers.
Hybrid Imaging
- PET/CT combines anatomical and functional imaging for comprehensive diagnostics.
- PET/MRI integrates detailed anatomical and metabolic information.
