Radiology in forensic medicine : 

Radiology in forensic medicine Radiology is defined as that special branch of medicine employing ionizing radiant energy in the diagnosis and treatment of disease. Forensic radiology comprises of the performance, interpretation, and reportage of those radiological examinations and procedures that have to do with court and law

Ossification centers : 

Ossification centers Bones are 1st formed as mesodermal condensations. The process of formation of bone from these mesodermal models is called ossification . There are 2centers of ossification for a bone. Primary center which forms the diaphysis of a bone. Secondary center forms epiphysis of bone. In embryonic life there are 806 primary ossification centers. At birth there are 450 centers. In an adult, there are 206 centers which is the number of d bones in a human body.

Rules for reading x-rays : 

Rules for reading x-rays Usually standard right sided x-rays are taken in A-P view. Exceptions are: jaw-oblique view elbow-AP and lateral view On x-ray, fusion is seen 6-12 months earlier than the actual bone, as the thin gap of non- union are noticed. Long bones ossify 1-2yrs early in females. The appearance and fusion of center vary in different individuals depending on environment, nutrition, endocranial disorders, vit-c deficiency.
