First Cardiac CT in Guyana- How and Why it was Done
Abstract:
Introduction:
A 64 detector CT was purchased by the
Georgetown Public Hospital Corporation (GPHC) and came into use there in May of
2018. First Cardiac CT was completed by technologist at GPHC on the 5th
of July 2019 directed by a resident radiologist.
Methods: The sequence of events was confirmed by references in electronic
media and official hospital logs and records. Images from GPHCs picture archiving
and communication system PACS were also used to critique the quality of the test
performed.
Results: The total radiation dose delivered was 33.9 mSv over two scans.
The calcium scoring accounted for only 1.1mSv of the total dose. The final image
quality was very good and without motion artefact and most importantly was good
enough to rule out the diagnosis in question with certainty.
Conclusion: The test was completed by
a team with minimal experience accomplishing excellent final image quality, though
with increased radiation dose. This was achieved by having motivated staff, and
experienced volunteers willing to advise remotely, and a very cooperative patient.
