These MRI images are demos taken on a desktop sized research scanner - the machine is designed to look inside small objects, e.g. rats, mice, hamsters... undergoing early stage drug trials, e.g. to measure the size of tumours and assess the effectiveness of new medicines. The access is through a 3~4" tube and you wouldn't fit your leg inside this thing. It sucks about the wait for your MRI but these images are not taken on a human-sized scanner.
