Medical Imaging and Radiation Safety Quiz

Ultrasound imaging uses sound waves to create images of internal body structures.

MRI stands for Magnetic Resonance Imaging, which uses strong magnetic fields and radio waves to generate images.

CT stands for Computed Tomography, a diagnostic imaging procedure that uses X-rays to create detailed cross-sectional images of the body.

X-rays are commonly used to visualize bones and diagnose fractures or abnormalities in bone structure.

MRI (Magnetic Resonance Imaging) is commonly used to visualize soft tissues like the brain and spinal cord due to its high contrast resolution.

Gamma radiation is commonly used in nuclear medicine imaging to visualize internal organs and functions.

Lead aprons are worn by personnel to shield against harmful radiation during medical imaging procedures.

PET scans use radioactive tracers to detect cellular function and metabolism within the body.

The primary concern with radiation exposure in medical imaging is the potential for DNA mutation and cellular damage.

Pregnant patients should inform healthcare providers about their pregnancy before undergoing medical imaging to assess risks and take appropriate precautions.

The sievert (Sv) is the unit used to measure the biological effects of ionizing radiation on the human body.

Gamma rays have the shortest wavelength among electromagnetic radiation, making them highly penetrating and ionizing.

The maximum permissible dose limit for radiation workers in the United States is 50 millisieverts (mSv) per year, as recommended by regulatory agencies.

Enhanced cognitive function is not a potential biological effect of radiation exposure; instead, radiation exposure can lead to various harmful effects such as DNA damage, cellular mutations, and cancer.
