The technique allows medical staff to identify exactly where the tumour is located, ensuring a more accurate delivery of treatment.
Dr Hanna, a Queen’s research fellow based at the Belfast City Hospital Cancer Centre is examining the new PET CT scanner which helps identify where the tumour is. This research has led to his team being awarded the St Luke’s medal in Dublin for the best radiotherapy research in Ireland.
The PET CT scan combines a CT scan and a PET scan in one scanning procedure allowing a more accurate diagnosis.
Dr Hanna explained: “Doctors need to be certain of the tumours position and size. In a PET scan a patient is injected with radiolabelled glucose which is taken up by the malignant cells. This glucose includes a molecule which emits a radioactive ray. By measuring where this is taken up we can more accurately define where the tumour is and how active that tumour is.
“The CT scan which is taken first can take up to three minutes. Then the PET part of the scan is taken which can take up to 45 minutes. The blacker the images, the greater the activity. High activity is typical of cancer.”
This is the first time a research team from Belfast has won the medal presented at the annual meeting of the Faculty of Radiologists of the Royal College of Surgeons in Ireland. Entries were submitted from across Ireland, the UK, Germany and Canada.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
