Table 1 Imaging techniques of interest in nutritional research

From: The challenges for molecular nutrition research 2: quantification of the nutritional phenotype

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
