Figure illustrates the three possible enhancement kinetic curves in breast MR Imaging (can also applied to other organs such as prostate), after the administration of Gadolinium-based contrast agent (GBCA). a) Curve type 1: progressive enhancement pattern • Typically shows a continuous increase in signal intensity throughout time. • Usually considered benign with only a small proportion of (5-10%) of malignant lesions having this pattern. b) Curve type 2: plateau pattern • Initial uptake (slow or fast) followed by plateau phase towards the delayed phases of the dynamic study. • Suspected for malignancy. c) Curve type 3: washout pattern • Has a relatively fast uptake (wash-in) and shows reduction in enhancement (wash-out) towards the delayed phases of the dynamic study. • Considered strongly suggestive of malignancy.
