Computerized tomography (CT) scans Mammograms Uses radio waves and magnets to generate detailed images of the body Use X-rays to examine breast tissue for cancer X-rays take pictures of organs from different angles and computers assemble them into 3-D models. Positron Emission Tomography (PET) scans Magnetic Resonance Imaging (MRI) Uses radioactive tracers to look at the uptake of sugar by cells

Similar to ultrasound scans that can be used to make an image of a person's internal body structures. positron emission tomography (PET) is an imiging technique that is used to visualize changes in human/animal body. Fluorine-18, tagged to glucose, is the standard radiotracer used for PET has an effective radiation dose of 14 mSv. Based on your understanding of radiation, explain why you would want to have an ultrasound scan over an PET scan if you needed an imaging scan?
