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






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






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






4. Gray






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






6. Surrounds root - cortical bone - radiopaque






7. 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.






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






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






10. Mature bone - muscle - nerve






11. Marked prominence that appears radiopaque.






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






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






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






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






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






17. 68 Degrees F






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






19. 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)






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






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






22. Cortical bone - radiopaque band above maxillary incisors






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






24. Linear prominence that appears radiopaque.






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






26. 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






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






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






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






30. Effects seen years - decades - or generations later






31. 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)






32. Hollow space - cavity that appears radiolucent






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






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






35. Continues from ramus; radiopaque band






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






37. 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)






38. Bony prominence posterior to maxillary third molar; radiopaque






39. Bony wall that divides 2 spaces - radiopaque






40. Mostly seen in mandibular nerve/blood supply vertical radiolucent lines






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






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






43. Cortical bone; J or U shaped radiopacity






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






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






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






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






48. Rounded prominence that appears radiopaque






49. U-shaped portion extending from ramus to ramus






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