Mater takes delivery of latest Toshiba CT scanner
Friday, 24 March 2017
Mater Hospital Brisbane is Australia’s first hospital to take delivery of the latest Toshiba volume imaging CT scanner that can scan an entire head or heart in a single rotation in approximately a third of a second.
The next generation machine has significant benefits for all patients being scanned but is of particular benefit to cancer, cardiac, and orthopaedic patients.
Mater Hospital Brisbane’s Deputy Director Medical Imaging Dr Rino Olivotto explains the benefits of the Toshiba Aquilion One Genesis machine.
“The clarity of images we’re seeing means we’re getting the results we need the first time.
“Traditionally, if a patient has hip replacements and we wanted to view their bladder for example, the interference from the replacements would give us no view of the bladder – however this new technology eliminates the artefact providing a clear picture of what’s going on immediately,” Dr Olivotto said.
The scanner has a 16 cm detector which not only allows whole head or heart scans in a single rotation, but it also means patients feel less ‘stuck inside a machine’–the sides angled out to allow the light in.
The speed with which the machine scans means results are provided much faster. The new scanner takes 0.75 seconds to perform a brain scan compared to 2-3 minutes with previous machines. This makes a significant difference for patients suffering anxiety or dementia for whom lying perfectly still and repositioning for multiple images is almost impossible.
“Anxious or distressed patients would often need to be sedated to ensure a clear image was taken, however the new technology means if a patient has a moment of stillness, a picture can be taken,” Dr Olivotto said.
“Patients presenting to the emergency department suffering chest pain are sent to have a chest scan to check the condition of their heart or lungs. With such excellent imaging, any problem present can be identified clearly.
“Cancer patients often require tracking scans during treatment and with this new machine we are able to reduce the amount of radiation the patient is exposed to by 28–56 per cent depending on what part of the body is scanned.
“Any technology which gives treating doctors the best information and lowers the risk of harm is a welcome addition to the tool kit,” Dr Olivotto said.
“When patients have the scan, many of them ask ‘Is that it?’ and are genuinely surprised when we say it is!” he said.
The scanner is part of Mater Medical Imaging at Mater Hospital Brisbane.
