Delineation of ROIs in T1-weighted imaging (T1WI) (a1–2, d1–2, g1–2), T2-fluid-attenuated inversion recovery (T2-FLAIR) (b = 800) (b1–2, e1–2, h1–2), and diffusion-weighted imaging (DWI) (c1–2, f1–2, i1–2). a1–2, b1–2, c1–2: man, 66 years old, with BMs in SCLC. a1, b1, and c1 represent the original lesions, and a2, b2, and c2 show the lesions after ROI delineation. d1–2, e1–2, f1–2: man, 45 years old, with BMs in AD. d1, e1, and f1 represent the original lesions, and d2, e2, and f2 depict the lesions after ROI delineation. g1–2, h1–2, i1–2: man, 49 years old, with BMs in NAD. g1, h1, and i1 represent the original lesions, and g2, h2, and i2 display the lesions after ROI delineation.
