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






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






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






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






5. Marked prominence that appears radiopaque.






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






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






8. Encases/supports teeth






9. Posterior to mandibular third molar






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






11. Rounded prominence that appears radiopaque






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






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






14. Continues from ramus; radiopaque band






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






16. Hollow space - cavity that appears radiolucent






17. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.






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






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






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






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






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






24. U-shaped portion extending from ramus to ramus






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






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






27. 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)






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






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






30. 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






31. Linear prominence that appears radiopaque.






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






33. Sharp - thornlike projection that appears radiopaque.






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






35. Sievart






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






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






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






39. Effects seen years - decades - or generations later






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






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






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






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






44. Dental x-ray machines operating 70 kVp or below: minimum 1.5 mm aluminum filtration - Dental x-ray machines operating above 70 kVp: minimum of 2.5 mm. of aluminum filtration.






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






46. Coulombs per kilogram






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






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






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






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