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. Two small openings (radiolucent) found on floor of nasal cavity->common exit is incisive foramen






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






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






4. Space between root and the lamina dura - thin - radiolucent line - healthy PDL is uniform thickness






5. U-shaped portion extending from ramus to ramus






6. Between canine and lateral incisor - depression is not always visible - radiolucent






7. Suggest that no matter how small the amount of radiation received - some biologic damage occurs.






8. Sharp - thornlike projection that appears radiopaque.






9. 'Arranged like a lattice'->soft - spongy bone located between 2 layers of cortical bone; spaces are trabeculae that are filled with bone marrow.






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






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






12. Bony wall that divides 2 spaces - radiopaque






13. Quantity of radiation received or total amount absorbed (more damage with tissue absorbing large quantities of radiation)






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






15. 68 Degrees F






16. Thin - curved areas of bone - radiopacities within nasal cavity and septum






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






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






19. Reproductive (ova - sperm). Effects are passed on to generations. Genetic damage cannot be repaired






20. Sharper of dark and light areas and how they are separated on film. Low kVp results in high contrast (many white and black areas - very little gray). Useful when diagnosing decay. High kVp results in low contrast (many shades of grade) Useful for per






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






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






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






24. Encases/supports teeth






25. Surrounds root - cortical bone - radiopaque






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






27. Cortical bone - radiopaque band above maxillary incisors






28. Anterior ramus of mandible; attachment for muscle of mastication; superimposed around maxillary tuberosity.






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






30. 16-20 square feet (at least 4x4) - Light tight - Safelight must be at least 4 feet from the working area






31. Effects seen years - decades - or generations later






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






33. Bump or nodule that appears radiopaque






34. Linear prominence that appears radiopaque.






35. Internal ridge of mandible muscle attachment - continuous with internal oblique ridge; radiopaque line






36. Tube that travels length of mandible - radiolucent; has cortical walls - houses inferior alveolar nerve






37. Gray






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






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






40. A form of secondary radiation - the result of x-rays that has been deflected from its path by an interaction with matter.






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






42. More damage can occur in younger or rapidly dividing cells






43. 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






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






45. Removes unexposed silver halide crystals and creates white/clear areas on film; black metallic silver remains on film.






46. The x-ray photon is deflected from its path during its passage through matter






47. Tubes within maxillary sinus that carry nerves - blood supply - radiolucent band with boundary of two radiopaque cortical bony lines






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






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






50. Darkness or blackness on film. If kVp is increased film will be darker. If decreased - film will be lighter
