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






2. Marked prominence that appears radiopaque.






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






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






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






6. Effects seen years - decades - or generations later






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






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






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






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






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






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






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






14. Bony prominence posterior to maxillary third molar; radiopaque






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






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






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






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






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






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






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






22. Sharp - thornlike projection that appears radiopaque.






23. 68 Degrees F






24. Sievart






25. Encases/supports teeth






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






27. Mature bone - muscle - nerve






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






29. 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)






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






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






32. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.






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






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






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






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






37. U-shaped portion extending from ramus to ramus






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






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






40. 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






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






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






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






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






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






46. 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.






47. Bump or nodule that appears radiopaque






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






49. Hollow space - cavity that appears radiolucent






50. Continues from ramus; radiopaque band
