RADT 142 Unit 1 Questions and Answers
Graded A+
What is the difference between diagnostic imaging and therapeutic radiology?
✔✔Diagnostic imaging focuses on creating images for diagnosis, while therapeutic radiology
(radiation therapy) is used to treat medical conditions, primarily cancer, by delivering targeted
radiation to tumors.
How does the ALARA principle apply to radiology?
✔✔The ALARA (As Low As Reasonably Achievable) principle aims to minimize radiation
exposure by using the lowest possible dose necessary for obtaining diagnostic images while
ensuring safety.
What are the main types of radiographic imaging techniques?
✔✔The main types of radiographic imaging techniques include X-rays, computed tomography
(CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine, each with specific
uses for different conditions.
What role does the radiologic technologist play in quality assurance?
1
,✔✔Radiologic technologists are responsible for ensuring imaging equipment is properly
maintained, functioning correctly, and producing high-quality images by adhering to established
quality assurance standards.
How is contrast media used in radiologic imaging?
✔✔Contrast media are substances used to enhance the visibility of specific areas in the body
during imaging, helping to highlight blood vessels, organs, or abnormal tissues in procedures like
CT scans or MRIs.
What are common challenges in radiographic imaging?
✔✔Common challenges include patient cooperation, ensuring proper positioning, managing
radiation exposure, handling complex imaging equipment, and ensuring clear communication
with patients and medical staff.
What factors influence the quality of a radiographic image?
✔✔Factors influencing image quality include proper patient positioning, exposure settings,
equipment calibration, the use of contrast media, and the experience of the radiologic
technologist.
How does radiation interact with the body in medical imaging?
2
, ✔✔Radiation interacts with the body by passing through tissues, with different tissues absorbing
varying amounts of radiation, allowing the creation of images that show the internal structures of
the body.
What is the significance of understanding radiation safety in radiology?
✔✔Understanding radiation safety is essential to minimize exposure to both patients and
healthcare providers while ensuring the diagnostic quality of the imaging procedure.
Why is patient positioning critical in radiography?
✔✔Patient positioning is crucial to obtain clear, accurate images, as proper alignment ensures
the correct area is imaged while reducing the need for retakes and minimizing unnecessary
radiation exposure.
What safety measures are implemented during radiographic imaging procedures?
✔✔Safety measures include using lead aprons for patients, limiting radiation exposure, ensuring
proper shielding, following safety guidelines for equipment use, and maintaining a sterile
environment when necessary.
