Patient Positioning. Positions used most frequently when writing x-ray orders: AP position: This view may be taken while the patient is standing or lying on the back (supine); the machine is placed in front of the patient. PA position: This view may be taken while the patient is standing or lying on the stomach (prone) with the x-ray machine aimed at the patient’s back. Lateral position: This view is taken with the patient standing or lying on the side..

Patient Positioning, cont'd. Most frequent positions, cont'd: Oblique position: This picture is taken with the patient standing or lying halfway on the side in the AP or the PA position. Decubitus position: In this view, the patient is lying on the side with the x-ray beam positioned horizontally..

X-Rays that Do Not Require Preparation. X-rays can penetrate solid material, such as bone. This produces a shadow that is recorded on film. Procedures that require the filming of bone structures or that are ordered to determine the position of other organs in relation to these structures can be performed without the need for preparation for the procedure..

Informed Consent and Other Forms. Diagnostic imaging procedures that are invasive and those that require the injection of contrast medium are not performed until the patient has signed an informed consent. It is the responsibility of the HUC to prepare the consent form for the patient’s signature. Special invasive x-ray and interventional procedures also require a signed consent. Other diagnostic imaging procedures that require a consent form may vary among health care facilities..

X-rays that Require Preparation and Contrast Media.

Guidelines for Scheduling X-ray Studies. X-ray studies of the lower spine and pelvis should be ordered first, before a barium enema or an upper gastrointestinal study is done. The presence of barium in specific parts of the body may obscure the portion of the body that is being studied. Abdominal studies that use ultrasound or CT should precede studies that use barium. Liver and bone scans and nuclear medicine studies may conflict with barium studies and should be done first..

Guidelines for Scheduling X-ray Studies, cont'd. Three x-ray studies requiring contrast media frequently are ordered at the same time. One or maybe two can be done on the same day; thus, the studies may have to be scheduled three or more days in advance. Order of scheduling: Intravenous urogram (IVU) Barium enema (BE) Upper gastrointestinal (UGI) or UGI and small bowel follow-through (SBFT).
