ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging; LN = lymphadenopathy.

Margin irreg = irregular/nodular (non - smooth) margin

Margin def = margin definition (ill- or well – defined)

T2 homog = homogeneity or uniformity of signal within the mass on T₂ weighted images

T2 hyper ≥50 = increased signal greater than that of normal myometrium in more than 50% of the total volume of the mass

T1 focal hyper = focal (single or multiple) T1 hyperintensity(ies) within the mass

DWI/ADC = diffusion trace - weighted image and ADC map

CE+=contrast enhancement

CE rim = predominantly or exclusively peripheral contrast enhancement
