"Modality is the term used in radiology to refer to one form of imaging, such as CT. It is often used in the plural, e.g., "various modalities can be employed to evaluate this liver lesion.""
"At times, modalities are subdivided into structural techniques and functional techniques. The former are modalities that primarily demonstrate the anatomy of body structures (e.g. CT or MRI), and the latter are modalities that emphasise function, such as bone scintigraphy, over anatomy."

"CT: attenuation, described as hyperattenuating, hypoattenuating or isoattenuating, with measured values in Hounsfield units"
"MRI: signal intensity, described as hyperintense, hypointense or isointense, always paired with the sequence, e.g. T2 hyperintense"
"ultrasound: echogenicity, described as hyperechoic, hypoechoic, isoechoic or anechoic"
"nuclear medicine and PET: uptake or avidity, described as avid or photopenic"

"Imaging modalities"
"Describing findings"
"NB As per the Radiopaedia style guide, when two modalities are combined, such as PET and CT, the two modalities are separated by a single dash only, i.e. PET-CT, PET-MRI, etc. We ask contributors not to use any format other than this one."
