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. Rate which exposure to radiation occurs and absorption occurs (more damage occurs with high dose due to rapid delivery and does not allow for repair)






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






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






5. Effects seen years - decades - or generations later






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






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






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






9. 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.






10. Used to increase incoming voltage to 65 -000 to 100 -000 volts used by the high-voltage circuit.






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






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






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






14. Mature bone - muscle - nerve






15. Posterior to mandibular third molar






16. Bump or nodule that appears radiopaque






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






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






19. Hollow space - cavity that appears radiolucent






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






21. Sharp - thornlike projection that appears radiopaque.






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






23. Cortical bone; J or U shaped radiopacity






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






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






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






27. 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)






28. Bony prominence posterior to maxillary third molar; radiopaque






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






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






31. Coulombs per kilogram






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






33. Marked prominence that appears radiopaque.






34. 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






35. Depression of bone; submandibular salivary gland found here; radiolucent; below mylohyoid ridge






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






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






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






39. Scooped out of depressed area of bone that appears radiolucent






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






41. Cortical bone - radiopaque band above maxillary incisors






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






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






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






45. Sievart






46. 'hooklike' - posterior to maxillary tuberosity; extension of medial pterygoid plate of sphenoid bone; radiopaque






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






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






49. Gray






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