Radiology 3

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Thin - curved areas of bone - radiopacities within nasal cavity and septum






2. Small lymphocyte - bone marrow - reproductive cells - immature bone






3. Reduces exposed silver halide crystals into black metallic silver a makes dark/black areas on film; unexposed silver halide crystals are unaffected by developer






4. Linear prominence that appears radiopaque.






5. The measurement of the number of electrons moving through a conductor. Measured in amperes (A) or milliamperes (mA)






6. Somatic effects that have a threshold; effects increase in severity with increasing absorbed dose. (Examples: Erythema - loss of hair - cataracts - and decreased fertility)






7. Bony prominence posterior to maxillary third molar; radiopaque






8. All cells except reproductive; effects are seen in person irradiated






9. Occurs frequently due to the high concentration of water in cells.






10. The measurement of electrical force that causes electrons to move from a negative pole to a positive one. Measured in volts (V) or kilovolts (kV)






11. Hollow space - cavity that appears radiolucent






12. Used to decrease voltage from the incoming 110- or 220-line voltage to the 3 to 5 volts used by the filament circuit.






13. Bump or nodule that appears radiopaque






14. 'Cortex'-> dense - outer layer; also called compact bone-appears radiopaque on film






15. V-shaped radiopacity at intersection of floor of nasal cavity and septum






16. Within maxillary sinus; acts as a division - radiopaque lines sometimes not visible






17. Hole in bone below mandibular premolars - blood supply to lower lip exits here; radiolucent; often misdiagnosed for periapical pathology






18. Continues from ramus; radiopaque band






19. Cell damage occurs through formation of 'free radicals'. Free radicals are formed when an x-ray photon ionizes water.






20. Opening/hole in bone that allows the passage of blood vessels/nerves and appears radiolucent






21. Aluminum disks between collimator and tubehead seal. Aluminum disks filter long wavelength - low energy x-rays from x-ray beam. 0.5 mm increments






22. Mature bone - muscle - nerve






23. Can control the current passing from the cathode to the anode.






24. X-radiation created when the primary beam interacts with a matter






25. Time between exposure to ionizing radiation and the appearance of observable clinical signs.






26. Located at the midline of anterior portion of hard palate behind maxillary central incisors; round radiolucency between roots of centrals






27. Sharp - thornlike projection that appears radiopaque.






28. Bump of bone - muscle attachment; lingual aspect of mandible - 'ring shaped' radiopacitiy below mandibular incisors.






29. Mostly seen in mandibular nerve/blood supply vertical radiolucent lines






30. An x-ray photon that has its path altered by matter.






31. Can increase or decrease the number of electrons passing through the cathode filament






32. Encases/supports teeth






33. Marked prominence that appears radiopaque.






34. Surrounds root - cortical bone - radiopaque






35. Produced when a high-speed electron dislodges an inner-shell electron from a tungsten atom and causes ionization of that atom. Occurs only at 70 kVp and above.






36. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.






37. Bony wall that divides 2 spaces - radiopaque






38. A direct function of the dose. No dose threshold; effects do not depend on the magnitude of the absorbed dose (Examples: cancer and genetic mutations)






39. Coronal part of alveolar bone - between teeth - cortical bone - radiopaque






40. 68 Degrees F






41. Surrounded by genial tubercle - hole in bone near mandibular midline - radiolucent






42. Pear shaped compartment - appears above maxillary incisors. Appears as a large radiolucent area above the maxilla.






43. Primary beam passes through glass window - insulating oil - tubehead seal. 0.5 to 1.0 mm of aluminum






44. Produced when an electron hits the nucleus of a tungsten atom or passes very close to the nucleus of a tungsten atom.






45. Extends from alveolar bone between maxillary centrals to posterior hard palate; seen as a radiolucent line






46. The penetrating x-ray beam that is produced at the target of the anode






47. A line of union between adjoining bones - found only in skull; appears as radiolucent line






48. Restricts size and shape of beam to lower patient exposure - Round: cone shaped beam-2.75 inches in diameter - Rectangular: Rectangular beam slightly larger than size 2 film- lowers patient exposure






49. Intersection of maxillary sinus and nasal cavity - radiopaque - cortical bone; above maxillary canine.






50. Cortical bone; J or U shaped radiopacity
