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






2. Sharp - thornlike projection that appears radiopaque.






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






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






5. U-shaped portion extending from ramus to ramus






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






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






8. Bump or nodule that appears radiopaque






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






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






11. 16-20 square feet (at least 4x4) - Light tight - Safelight must be at least 4 feet from the working area






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






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






14. 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.






15. Effects seen years - decades - or generations later






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






17. Rounded prominence that appears radiopaque






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






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






20. Encases/supports teeth






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






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






23. 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






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






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






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






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






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






29. Posterior to mandibular third molar






30. Marked prominence that appears radiopaque.






31. Mature bone - muscle - nerve






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






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






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






35. Cortical bone; J or U shaped radiopacity






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






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






38. Bony wall that divides 2 spaces - radiopaque






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






40. Bony prominence posterior to maxillary third molar; radiopaque






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






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






43. 'Cheekbone'; cortical bone; radiopaque band extending from zygomatic process.






44. Closed - pointed cone-high production of scatter - not used any longer.






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






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






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






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






49. Surrounds root - cortical bone - radiopaque






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