I was surfing web, and found 2 blogs on MRCP preparation, both were good. I learned a new sign (Clinical Sign) from these blogs, i.e., Franks Sign.
See the Ear Lobule in the Picture
Frank's sign is a diagonal crease in the lobule of the auricle : 
Grade 3 - a deep cleft across the whole earlobe
Grade 2a - crease more than halfway across the lobe
Grade 2b - crease across the lobe, but superficial
Grade 1 - lesser degree of wrinkling
Ear lobe creases are associated statistically with coronary artery disease in most of the population groups.
