What are the three routine projections for the Hand series | PA Projection Oblique Projection Lateromedial Projection: Extended or Fanned |
PA projection Collimation? patient positioning? IR placement? Central Ray? Shield | 8x10 Seated at the end of the table with forearm resting on table Center IR to the MCP joints and long axis to long axis of forearm and hand Perpendicular to the third MCP joint Shield is required |
PA Oblique projection Collimation? patient positioning? IR placement? Central Ray? Shield | 8x10 Seated at the end of the table with forearm resting on table Center IR to the MCP joints and long axis to long axis of forearm and hand Perpendicular to the third MCP joint Shield is required |
Lateromedial projection Extended and Fanned Collimation? patient positioning? IR placement? Central Ray? Shield | 8x10 Seated at the end of the table with forearm resting on table and hand in the lateral position with ulnar side down Center IR to the MCP joints and long axis to long axis of forearm and hand Perpendicular to the second digit MCP joint Shield |
