The advantages of the cephalad and caudad angled views of the pelvis in lymphography are discussed and illustrative case reports are presented.
The cephalad or inlet view of the pelvis shows excellent separation of the iliac lymph nodes with good visualization of the nodal outlines in the axial projection. The hila of the iliac lymph nodes can be readily differentiated from pathologic filling defects.
The caudad angled or outlet view of the pelvis provides satisfactory visualization of the inguinal lymph nodes in the axial projection.
The angled views are useful adjunct to the routine views, especially when the lymphographic findings are subtle.
