Attached are two coronal MRI images of a mouse lying on its side, with the left image taken 2mm lower than the right one. Can anyone tell me if the part circled by the red line is the hindlimb of the mouse? If not, what is it (some organ?..)? And is the part indicated by the blue square the abdomen? I am new to in vivo MRI images but this must be very obvious to someone with experience. Thanks!
