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. 68 Degrees F






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






3. Encases/supports teeth






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






5. Gray






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






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






8. Cortical bone - radiopaque band above maxillary incisors






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






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






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






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






13. U-shaped portion extending from ramus to ramus






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






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






16. 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)






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






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






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






20. 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






21. Hollow space - cavity that appears radiolucent






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






23. Bony wall that divides 2 spaces - radiopaque






24. Coulombs per kilogram






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






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






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






28. Continues from ramus; radiopaque band






29. 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






30. Sievart






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






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






33. 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)






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






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






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






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






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






39. Rounded prominence that appears radiopaque






40. Sharp - thornlike projection that appears radiopaque.






41. Bony prominence posterior to maxillary third molar; radiopaque






42. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.






43. Mature bone - muscle - nerve






44. Linear prominence that appears radiopaque.






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






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






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






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






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






50. Effects seen years - decades - or generations later
