Include distal radius and ulna MC area
Criteria :
Structure shown : distal radius and ulna , carpals and at least to mid metacarpal area are visible.trapezium and scaphoid should be well visualized,with only slight superimpostion of other carpals on their medial aspect
Position: long axis of hand and wrist ,forearm should be aligned with IR
True—> evident by ulnar head being partially superimposed by distal radius
2- the proximal third , fourth , fifth metacarpals should appear mostly superimposed
