Crossword Puzzle Challenge
The crossword puzzle offers a very efficient tool for gaining CPD
points. It does not take long to create. The puzzles below were team
efforts from the respective departments and the authors (and their
departments) issue a challenge to other nuclear medicine
departments to form a team and create a better crossword puzzle for
the next newsletter. There should, however, be some ground rules.
Firstly, the crossword needs to be on a specific theme (eg. PET,
GIT imaging, SPECT/CT etc) not just general nuclear medicine.
Secondly, the puzzle needs to contain between 30-40 clues. Submit
your department crossword for the next edition of the newsletter.

The Doctor of Health Science
Introduction
The Doctor of Health Science (DHlthSc) at CSU is a
professional doctorate that allows candidates to pursue
a research higher degree of the same standard as the
PhD but within a structure that is aimed at improving
professional practice. Specifically, it offers a research
based approach for provision of solutions relevant to
the professions and industry.
Professional doctorates aim to provide a tool for
