The gray-scale (a) and color Doppler sonography (b) show arterial flow (white arrow) within the polypoid mass from the cystic artery. On the T1-weighted fat-saturated spoiled gradient recalled echo (c) and fat-saturated T2 fast spin-echo MRI images (d), the polypoid gallbladder tumor demonstrates intermediate signal intensity on T1-weighted image and slightly high on T2-weighted image to that of liver parenchyma
