Dorsal and lateral decubitus patient positioning for abdominal x-ray exams

The dorsal decubitus (right or left) position is a good alternative to obtaining a lateral decubitus or erect abdominal x-ray image when a patient cannot stand or lie on their side. It can provide information regarding pneumoperitoneum and air fluid levels in cases of suspected acute abdominal trauma.

AP abdominal projection x-ray positioning techniques

The anteroposterior (AP) radiograph taken with the patient in a supine position is the basis of the majority of plain-film examinations of the abdomen. The abdominal film obtained with the patient in an erect position is ordered routinely, but rarely adds significant diagnostic information. Dr. Naveed Ahmad offers an alternative with an upright-position film that may be helpful in patients with suspected bowel obstruction.

Tips and techniques for decubitus and oblique chest x-rays

Lateral decubitus chest x-rays are helpful for determining effusions and pneumothorax. Oblique-view films may be requested for a clutch of reasons, such as determining the site of origin of an intrathoracic lesion. Dr. Naveed Ahmad concludes his series on chest x-ray techniques with step-by-step guidelines to positioning these views.
