Type | Abbreviation | Principle | Application |
---|---|---|---|
Röntgen array | X-ray | Different absorption of ionizing radiation based on tissue density | Skeletal and dense inner organs |
Computed tomography | CT or CAT scan | Focused X-ray pictures in several “slices” computerized to 3D images | Accurate imaging of organs and tissues |
Positron emission tomography | PET | Injected radio-tracers are detected as gamma emitters | Detect blood flow, metabolic changes |
Magnetic resonance | MR | Charged molecules are realigned in a strong and oscillating magnetic field with different rates | Soft tissues like adipose, muscle, heart, joints can be accurately quantified |
Magnetic ressonance spectroscopy | MRS | MR combined with spectroscopy of protons, phosphorus, sodium, etc. | Linked to expression and regulation of transgenes |
Bioluminscence | – | Luciferase promotes light emission upon activation | Detection of inflammatory response caused by supply of nutrients |
