b800 of lFOV (A, C, E), b800 of rFOV (B, D, F). According to the image, rFOV images have a greater resolution and more clear contours than lFOV images. In A, B, on the b800 DWI image of lFOV, as depicted by the white solid circle, the head of the pancreas is obscured by the adjacent gallbladder and surrounding intestines, and the partial display is not clear. In C, D, the position shown by the white pointed head, the pancreas appears pseudo-diffusion-restricted in lFOV due to the convolution effect of the surrounding intestine, this effect disappears in rFOV DWI. In E, F, demonstrate that the diffuse look of the body and tail of the pancreas on DWI images is distinct, because of that the head, body, and tail of the pancreas have distinct cellular compositions.
