front 1 radiopaque | back 1 not easily penetrated, white |
front 2 radioluscent | back 2 easily penetrated, black |
front 3 radiograph | back 3 actual image |
front 4 x ray | back 4 photon beam/electromagnetic radiation |
front 5 attenuation | back 5 reduction in the number of x-ray photons in the beam as they interact with matter and lose energy due to scattering/absorption |
front 6 radioluscent to radiodense | back 6 air, fat, water, bone, metal |
front 7 one view is no view | back 7 single radiograph only shows length and width, you need a second radiograph to show depth |

front 12 what four factors indicate image quality on a radiograph? | back 12 density, contrast, detail, distortion |
front 13 what are the five potential types of results on a routine radiograph? | back 13 positive for suspected diagnosis, negative for suspected diagnosis, negative for suspected diagnosis but raises suspicion for another diagnosis, inconclusive, wrong |
front 14 radiologist | back 14 medical doctor |
front 15 radiographer | back 15 tech |
front 16 quadruple aim | back 16 improved patient experience, better outcomes, reduced costs, improved clinician experience |
front 17 free radicals | back 17 major contributor to damage from radiation is through radiation changing a water molecule into a new form called a free radical chemically highly active and can have reactions with genetic molecules of the cell (such as DNA) |
front 18 standard imaging | back 18 film/screen |
front 19 flouroscopy | back 19 dynamic/continuous real-time imaging |
front 20 computed radiography | back 20 use of phosphor screen (instead of film) to produce a digital image |

front 22 air | back 22 black on xray |
front 23 fat | back 23 gray-black on xray |
front 24 water | back 24 gray on x-ray |
front 25 bone | back 25 white on x-ray |
front 26 contrast media | back 26 appears bright white outlined on x-ray |
front 27 what are the 2 contrast enhanced studies? | back 27 arthography (joint and soft tissue) myelography (spinal cord, nerve root, dura mater) |
front 28 what two criteria are used for imaging? | back 28 ottawa rules and american college of radiology appropriateness criteria (ACR) |
front 29 ottawa ankle rules | back 29 x ray required if there is pain in the malleolar zone and bone tenderness at posterior edge or tip of lateral or medial malleolus |
front 30 ottawa foot rules | back 30 x ray required if there is pain in midfoot zone bone tenderness at fifth metatarsal or navicular |
