Preface
My main reason for writing this book is to introduce Bayesian approaches to
analysis of randomnes s and uncertainty in nuclear imaging. Bayesian meth-
ods use d in imaging res earch and pr esented in many imaging texts do not

ena, which is quite unfortunate. Most users who utilize statistical tools in
their research consider the probability as the frequency of occurrence of some
random phenomena. The word “random” indicates that if an identical experi-
ment is performed repetitively the results may be different and unpredictable.
We all have gone through examples of
