WebApr 11, 2024 · The superiority of breast MRI's screening performance compared to x-ray and US-based techniques stems from its ability to provide concurrent anatomical and functional information on breast lesions via various MRI sequences (T1-weighted [T1W], T2-weighted [T2W], diffusion-weighted imaging (DWI), and, most importantly, contrast-enhanced T1W ... WebDec 30, 2024 · T2 signal intensity. TNBC: 108/172 (62.8%) lesions elicited high T2 signal intensity, 60/172 (34.9%) lesions elicited low T2 signal intensity, and 4/172 (2.3%) lesion was indistinct in T2-weighted images. The increased T2 signal is due to the presence of necrotic areas which elicits high signal on T2 WI.
