CCD Diagnostic Imaging Exam Questions
With Correct Answers
what are the categories of diagnostic imaging? - CORRECT ANSWER✔✔--x-ray:
| | | | | | | | | |
plain, CT, tomograms, 3D reconstruction, fluoroscopy
| | | | |
-ultrasound/echocardiography
-magnetic imaging |
-nuclear medicine |
-angiography
radiation exposure - CORRECT ANSWER✔✔-clinician: eliminate when possible
| | | | | | |
-protective lead aprons, skirts, neck shields
| | | | |
-distance
-lead lined glasses, gloves
| | |
patient: limit when possible
| | |
-least exposure necessary (ALARA)
| | |
-cumulative
-"first do no harm"
| | |
-cancer (thyroid)
|
-cataract
-pregnancy
, what does ALARA mean? - CORRECT ANSWER✔✔--"as low as reasonably
| | | | | | | | | |
achievable"
-use the minimum level of radiation needed in imaging to achieve the necessary
| | | | | | | | | | | | |
results
-American College of Radiology adopted statement in 2011
| | | | | | |
-based on FDA released statement in 2010
| | | | | |
-image gently: dose reduction effort in pediatric imaging
| | | | | | |
-image wisely: dose reduction campaign in adults
| | | | | |
-use non-radiation studies when reasonable
| | | |
-limit re-exposure for tracking (stones, cancer progression, bone healing) when
| | | | | | | | | |
other alternatives are available

describe millisievert (mSv) - CORRECT ANSWER✔✔--International System of Units
| | | | | | | |
(SI) measure to determine ionizing radiation exposure in patient
| | | | | | | | |
-1 mSv is the dose produced by exposure to 1 milligray (mG) of radiation
| | | | | | | | | | | | |
-equivalent to "the average exposure of background radiation over a period of 1
| | | | | | | | | | | | |
year when living in the United States, excluding radon exposure"
| | | | | | | | |
-1 mSv = 100 mrem
| | | |
-1 mSv = 0.1 rad
| | | |
-healthcare/radiation workers are allowed 50 mSv exposure per year | | | | | | | |
-whole body radiation exposure LD50/30 is 5,000 mSv (acutely)
| | | | | | | |
describe rad (gray) - CORRECT ANSWER✔✔--measure of energy absorbed in
| | | | | | | | | |
tissue or bone | |
-1 gray = 100 rad
