Mandibular Rami
PA IR Size: 8x10 LW SID: 40"" Page #'s: 2:344,306	Positioning:   • Pt seated or prone   • Forehead & nose on grid	CR Entrance & Angle:   • CR exits Acanthion   • Collimation:   • Close Respiration:   • Suspend Best to Determine:   • Entire mandible   • Mandibular rami & body	Eval Criteria:   • Primarily used to demonstrate medial/lateral displacement of fragments or fracture in the rami   • NR by symmetric rami & body bilaterally
PA axial IR Size: 8x10 LW SID: 40"" Page #'s: 2:345,308	Positioning:   • Pt seated or prone   • Forehead & nose on grid   • (Like PA but angle + condylar processes)	CR Entrance & Angle:   • CR exits Acanthion   • 20°-25° cephalic Collimation:   • Close Respiration:   • Suspend Best to Determine:   • Mandible & Condylar processes   • Mandibular rami & body	Anatomy to IR:   • MSP centered to IR & OML _|_ to IR, Acanthion to crosshairs Eval Criteria:   • Primarily used to demonstrate medial/lateral displacement of fragments or fracture in the rami   • NR by symmetric rami & body bilaterally
