From 6 consenting patients requiring a
medical scan, 3 are chosen at random to undergo a positron emission
tomography (PET) scan, the others receiving a magnetic resonance
imaging (MRI) scan. Image quality is ranked in order by a hospital
consultant from 1 (best) to 6 (worst). Describe how you would test
: scan quality is
unrelated to scan method against (i)
:PET scans are
better (ii)
:the scans differ
in quality depending on whether they are from PET or MRI.
Interpret the finding that the consultant rates the three PET scans
as the three highest quality images.

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
