Position of patient Place patient in lateral recumbent, dorsal decubitus, or upright position. Have patient suspend respiration for exposure. Purpose and Structures Shown Clear image of lateral pelvis. Lumbosacral junction, sacrum, coccyx, superimposed hip bones, and upper femur. Video Credit : TheXra圜hic Pelvis Lateral Left or Right If pelvis is deep, palpate for iliac crest and adjust position of IR so that its upper border will project 1 to 1.2 inches (2.5to3.8cm) above crest.Ĭentral ray Perpendicular at midline of patient about 2 inches (5cm) inferior to ASIS and 2 inches (5cm) superior to pubic symphysis in average-sized patients. Heels should be placed about 8- 10 inches (20 to24cm) apart. Immobilize legs with sandbag across ankles, if needed. Check distance from ASIS to table top on each side to be sure that pelvis is not rotated. Center IR midway between ASIS and pubic symphysis. Unless contraindicated due to trauma or pathologic factors, medially rotate feet and lower limbs about 15 -20 degrees to place femoral necks parallel with plane of the IR. Medial rotation is easier for patient to maintain if knees are supported. Position of patient Supine position. Have patient suspend respiration for exposure. Purpose and Structures Shown Clear image of entire pelvis. Also demonstrates head, neck, trochanters, and proximal one third or one fourth of shaft of femur. This article discusses radiographic positioning to show the hip and pelvis for the Radiologic Technologist (X-Ray Tech).
