Radiology and diagnostic imaging are used synonymously. Imaging modalities frequently used in marine mammal medicine include radiography, ultrasound, CT (computed tomography) and MRI (magnetic resonance imaging). PET-CT, fMRI and nuclear scintigraphy have also been used but are beyond the scope of this site.
