Comparing the supine and erect pelvis radiographic examinations: an evaluation of anatomy, image quality and radiation dose.

Objectives: Pelvis radiographs are usually acquired supine despite standing imaging reflecting functional anatomy. We compared supine and erect radiographic examinations for anatomical features, radiation dose and image quality.

Methods: 60 patients underwent pelvis radiography in both supine and erect positions at the same examination appointment.

Optimum Positioning for Anteroposterior Pelvis Radiography: A Literature Review.

Aim: Pelvic radiography is used for the identification of hip joint changes, including pathologies such as osteoarthritis. Several studies have recommended that the position for this radiological procedure should be standing, not supine, to reflect the functional appearances of the hip joint. The aim of this review was to evaluate pelvis radiography positioning with respect to the image appearances and information provided for clinical decision-making.
