Acute Abdominal 115
Acute Abdominal
| Question | Answer |
|---|---|
| Its not recommended to use _____________ during abdominopelvic procedures | Gonadal shielding |
| Increase kVp and decrease mAs to- | Minimize patient dose |
| ________ are the most common cause of repeat imaging | Artifacts |
| increasing _____= more penetration (quality), less absorption (dose) | kVp |
| decreasing ___ =less photons (quantity) (less dose) | mAs |
| mA x seconds =mAs | reciprocity |
| Less photons = less dose | 15% rule |
| Procedural Guidelines | Exposure taken on suspended inspiration |
| Anterior, Superior illiac spine | Asis |
| Asis is equidistant to the tabletop, this means there is no ______ | Rotation |
| AP Abdomen, Supine (KUB) Image Evaluation Criteria | Superior aspect of the kidneys to the pubic symphysis and lateral border of anatomy |
| AP Abdomen, Supine (KUB) Image Evaluation Criteria | Centered vertebral column |
| AP Abdomen, Supine (KUB) Image Evaluation Criteria | Ribs, pelvis, and hips equidistant to the edge of the image |
| AP Abdomen, Supine (KUB) Image Evaluation Criteria | No rotation |
| AP Abdomen, Supine (KUB) Image Evaluation Criteria | Spinous processes in the center of the lumbar vertebrae Alae or wings of the ilia symmetric |
| Acute Abdominal Series | PA Chest AP Upright Abdomen to include diaphragm AP Supine Abdomen to include pubic symphysis |
| Flat and Upright | AP Upright Abdomen to include diaphragm AP Supine Abdomen to include pubic symphysis |
| Supine only (KUB)* | most common *kidneys, ureters, bladder |
| you can see rotation in the image by viewing the | Spinous process |
| AP Abdomen, Upright purpose is? | to see air/fluid levels |
| AP Abdomen, Upright position lets us view the | Diaphragm without motion |
| If you see air bubble is flat on bottom, the position the image was taken must be? | Upright |
| PA Abdomen | Rarely done Reduces Patient dose Best if kidneys are not of primary interest |
| If a patient cannot stand, _____________ is usually performed | Left lateral decubitus |
| Left lateral decubitus shows? | Shows free air over the liver |
| PA Abdomen reduces patient dose because | reproductive organs are more anterior |
| Patient lies on left side for at least _______ before the exposure to allow air to rise | 5 minutes |
| Wait _______ for very small amounts of air | 10-20 minutes |
| Patient in lateral recumbent position (usually left) lays with the affected side _____ for fluid | down |
| Patient in lateral recumbent position (usually left) lays with the affected side _____ for air | up |
| Patient in lateral recumbent position ______ if affected area is unknown | Unknown = lie on left side |
| AP/PA Abdomen, Lateral Decubitus Position: patient position | On a radiolucent pad (elevate anatomy of interest), Knees flexed slightly for stability |
| AP/PA Abdomen, Lateral Decubitus Position: Central ray position | Perpendicular to IR Through MSP and 2 inches above iliac crests (to include diaphragm) |
