| Term | Definition |
| Flat plate | ABD 1V |
| Obstruction series | ABD 3V |
| Kidneys, ureters, bladder | KUB |
| Obstruction series | Test performed to demonstrate perforated hollow viscus or obstruction (excessive air will be seen in the small bowel) |
| Obstruction series | Test performed to detect origin of an infection, intra-abdominal mass, post-op pain |
| Obstruction series | a.k.a. 3V abdomen, three-way abdomen, acute abdominal series |
| Expiration | Breathing instruction for abdomen films |
| Inspiration | Breathing instruction for diaphragm shots |
| Voluntary | Any type of movement that is controlled |
| Involuntary | Type of movement that cannot be controll, e.g. peristalsis, heart beat |
| Ileus | An obstruction of the small intestine wherein the proximal jejunum is markedly expanded with air caused by lack of peristalsis |
| Adynamic, Paralytic | Type of bowel obstruction due to the cessation of peristalsis |
| Mechanical | Type of obstruction caused by a physical blockage ie: tumor, adhesions |
| 32 - 40 mas @ 75 kvp | Average technique for abdomen XR's |
| KUB | Same as a flat plate; when kidneys are not included on flat plate, do separate kidney shot; when bladder is not included on flat plate do additional bladder shot |
| AP kidneys | Pt. supine; 11x14 or 14x17 CW in bucky; 40" SID; CR perpendicular to a point midway between xiphoid tip and crest; Take exposure on exhalation |
| Axial bladder | 10x12 IR in bucky crosswise; R/L marker; pt. supine; CR angle 15 – 20 degrees caudally to lowermost portion of ASIS; full exhalation |
| Axial bladder | Demonstrates urinary bladder unsuperimposed by other structures |
| Obstruction series | Consists of an AP Supine Abdomen (same as flat plate), AP Erect Abdomen, and AP Diaphragm (erect); i.e. (3) 14x17 IR'S |
| Flat plate abdomen | A ____ _____ _______ is included as a part of other studies: e.g. IVP scout, AP lumbar spine, UGI scout, BE scout, Post Evac BE, Small Bowel films |
| Ascites | Invasion of fluid (additive disease) |
| Pneumoperitoneum | Presence of air in the peritoneal cavity |
| Abdominal Aortic Aneurysm (AAA) | Localized dilation of the abdominal aorta |
| Bowel Obstruction | Blockage of the bowel lumen |
