The Discovery PET/CT 690™ provides a high image quality. With one of the highest-rated sensitivities in the industry, the scanner is designed to potentially improve cancer detection, enable faster scans and reduce dose requirements. The Discovery PET/ CT 690 aids workflow and patient comfort with unique features like the 70cm wide bore with a full PET and CT field of view, a large patient table and a 2m horizontal scan range for full head-to-toe imaging. Combined, these efficiencies allow patients to finish exams in a timely manner and provide images quickly for physicians to review.
Lower Dose, High Image Quality
In recent years, there has been a growing proportion of people attending Ascot Radiology, who have expressed concern about radiation dose. The dose reduction solutions offered by the Discovery PET/CT 690 have enabled Ascot Radiology to significantly reduce the amount of radiation their patients are exposed to without compromising image quality or their diagnostic confidence. Further, due to the high sensitivity of the PET component, the radiation dose is further reduced to lower radio isotope dose injection 18F-FDG.
With ASiR (Adaptive Statistical Iterative Reconstruction), the CT dose can be reduced up to 40% (1) and improve low contrast detectability (LCD) by 30%.
“We think it is a very useful benefit to be able to offer our patients a PET/CT with the same radiation dose as just a CT scan on a standard scanner. We do all of our imaging on the Discovery PET/CT 690 using ASiR as we have found that the dose levels are much less than what they are when we use a different scanner. When we add in the PET scanner component, the dose is about what we would have normally used in a CT scan before ASiR,” Dr Rogers said.
“The ASiR feature has also enabled us to see exceptional reductions in metal artefacts. For example, we can now even see the joint between the metal prosthesis and the image is not distorted by the metal. This is a very positive feature.”
