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






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






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






4. Area of body exposed total body produced more adverse effects






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






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






7. Located above maxillary premolar/molar teeth - border is made up of cortical bone; sinus cavity is radiolucent compartment






8. Marked prominence that appears radiopaque.






9. Mature bone - muscle - nerve






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. Do not occur in dentistry






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






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






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






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






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






17. Bony prominence posterior to maxillary third molar; radiopaque






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






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






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






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






22. 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






23. Surrounds root - cortical bone - radiopaque






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






25. Rounded prominence that appears radiopaque






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






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






28. Continues from ramus; radiopaque band






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






30. Posterior to mandibular third molar






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






32. Tube that passes through bone - contains nerve canals/blood vessels/and appears radiolucent






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






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






35. Cortical bone; J or U shaped radiopacity






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






37. Effects seen years - decades - or generations later






38. Coulombs per kilogram






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






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






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






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






43. 68 Degrees F






44. Occurs very little; most photons pass through cell with little or no damage






45. Sievart






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






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






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






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






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