Question

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

Answer 1

Mammograms - It is x-ray of mammary glands . 3 option best describe it ( use X-rays to examine breast tissue for cancer ).

CT scan -  It is best described by last option ( X rays take picture of organs from different angles and computers assemble them into 3 D models ) .

PET - It is best described first option ( uses radioactive traces to look at the uptakes of sugar by cells ) . Here , radioactive sugar is given (either ingested or injected into a vein ) and 3 D computerized pictures are obtained of different areas and uptake of glucose is observed .

MRI - It is best described by 2 option ( uses radiowaves and magnets to generate detailed images of the body ) . Images of organs and tissues are created .
