Science in Medicine - Positron Emission Tomography (PET) with Case Studies

PET is unique in its ability to non-invasively detect metabolic activity of various organs inside the body.  PET is particularly effective in the detection of cancer, and its remission or otherwise after treatment as it gives the current metabolic activity of the cancerous tissue.
Short-lived radioactive isotopes are used in PET to minimize exposure to nuclear radiation and provide information with acceptable exposure levels.
The slides of my talk on PET are published here.  They attempt to introduce the complex subject of nuclear radiation and its detection in an accessible way.  The efficacy of PET in detection of various ailments is demonstrated by looking at some case studies. (unfortunately some of the information about the websites is lost but I implicitly acknowledge the pictures that I have used)
