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. Sievart






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






3. Bony wall that divides 2 spaces - radiopaque






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






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






6. Bony prominence posterior to maxillary third molar; radiopaque






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






8. Cortical bone - radiopaque band above maxillary incisors






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






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






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






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






13. Cortical bone; J or U shaped radiopacity






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






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






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






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






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






19. Surrounds root - cortical bone - radiopaque






20. Effects seen years - decades - or generations later






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






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






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






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






25. Mature bone - muscle - nerve






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






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






28. Sharp - thornlike projection that appears radiopaque.






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






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






31. Linear prominence that appears radiopaque.






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






33. Rounded prominence that appears radiopaque






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






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






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






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






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






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






41. Bump or nodule that appears radiopaque






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






43. 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)






44. 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






45. 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.






46. Superior to internal oblique ridge; anterior border of ramus ends in external oblique ridge; radiopaque band






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






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






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






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