Vancouver now home to fastest PET/CT scanner in Canada
A new cancer screening machine that recently began operating at the BC Cancer Centre in Vancouver is the fastest and most advanced in Canada, according to officials.
The Quadra PET/CT scanner is the first of its kind in the country, and it can capture a much larger picture than previous generations and is about 22 times more sensitive.
'It is the equivalent of four PET scanners put together, and essentially the area covers from the head to the pelvis,' said Dr. François Bénard, senior research director at BC Cancer and radiology professor at the University of B.C. 'We can image this entire area of the body in one shot, so you can do things that we could not do before.'
In a nutshell, the new scanners give better quality images in less time and requires less radioactive drugs than previous machines, he told CTV News.
A PET/CT scanner combines two imaging devices, positron emission technology, which looks at biochemistry, and computed tomography, which provides anatomical information. A PET scan requires an injection of a radioactive substance called a tracer, while a conventional CT scan does not. B.C. is home to three PET/CT machines, in Vancouver, Victoria and Kelowna.
Notably, the new Quadra machine is the fastest of its kind, which means more scans can be performed and patients get a more comfortable experience. Bénard says it can take more time to position a patient in the machine than take the picture itself.
'When I started my career, it would take two hours to take a PET scan, now we can get a better PET/CT scan in less than 30 seconds,' he said.
Bénard added that those getting a PET scan on an older machine need not worry—they are also very precise.
'If you're not getting a PET scan on that machine you should be reassured. BC Cancer has very modern instruments at other sites,' he said.
What this new scanner will do right away is add capacity for more diagnostics and provide research opportunities in the radiopharmaceutical field at UBC, according to Bénard.
In May, the BC Cancer Centre in Vancouver also got a state-of-the-art photon-counting CT scanner.

New training for Sask. pharmacists will allow for medication substitutions
Prescription drugs are seen on shelves at a pharmacy in Montreal on March 11, 2021. THE CANADIAN PRESS/Ryan Remiorz New training in Saskatchewan will allow pharmacists in the province to substitute medications under certain conditions. According to the province, pharmacists will be able make faster adjustments in specific cases, such as supply disruptions or shortages of a prescribed drug, allowing them to prescribe an alternative. 'Pharmacists are trusted, highly skilled health professionals, who, in many communities, are the primary access point for health-care services,' Health Minister Jeremy Cockrill said in the news release. 'Giving pharmacists the ability to prescribe alternative medications means Saskatchewan patients can benefit from more timely and accessible health care.' In addition to supply shortages, pharmacists will also have the ability to prescribe an alternative drug in other cases, including when a drug is withdrawn from the market, if the patient's safety is at risk, or if the patient is unable to take the drug and would benefit from a different one or a different way of taking it. Pharmacists will be required to take the training, meet competency requirements, and follow mandatory guidelines under the Saskatchewan College of Pharmacy Professionals. 'Pharmacists are the health system's medication experts. By expanding pharmacists' scope and enabling them to replace a patient's prescribed medication, the government is increasing health system capacity for Saskatchewan residents,' Pharmacy Association of Saskatchewan CEO Michael Fougere said in the release. Nine other provinces and territories have implemented similar policies, according to the news release. Pharmacists in Saskatchewan were first given the authority to prescribe for four minor ailments in 2012, with that list growing to more than 30 conditions.

‘Like a ticking time bomb': Saskatoon seeing more cases of Dutch elm disease
The City of Saskatoon is renewing calls for residents to be vigilant in the fight to prevent the spread of Dutch elm disease, after several cases were identified in multiple neighbourhoods across the city. On Monday the City identified positive cases in three elm trees in the Montgomery neighbourhood, two cases in Riversdale, one in Caswell Hill and an unspecified number of cases in City Park and Sutherland. Some cases are near where previous cases have been identified since Saskatoon's first case of Dutch elm disease in 2015. Others are in areas that have been un-affected until now. 'Kind of all over the city, we're seeing it in various places,' said Cate Francis, a parks superintendent with the city's urban forestry division. 'It's likely due to wood being moved around.' Francis said a combination of complacency with ongoing regulations and a lack of understanding from the general public has caused cases to increase over the last number of years. Following a positive case of the disease, the City immediately removes all positive trees and looks for stored elm wood in the immediate area. Samples are collected from symptomatic trees within one kilometre of an infected tree, and staff sweep a one-kilometre radius for any stored wood once a Dutch elm case is confirmed. Despite continued efforts reminding people not to store elm wood, city crews have already destroyed more than 4,000 kilograms of seized wood this summer. 'One log is almost like a ticking time bomb,' Francis said. 'If that fungus that causes Dutch elm disease [is] on that log and elm bark beetles get into that log, they get the fungus on them, and they will fly to nearby healthy trees to feed and transmit that fungus to all of those trees.' Dutch elm disease is caused by a fungus spread by elm bark beetles that breed under the bark of dead or dying elm wood. According to the province's Forest Resources Management Act, potential fines can reach $250,000 for individuals and $1,000,000 for corporations, or imprisonment of up to five years for transporting or storing elm wood. Residents are also encouraged to avoid pruning elm trees from April 1 to August 31, as freshly-cut wood attracts the beetles — but that hasn't stopped the disease from flourishing in recent years. 'What started off as a big Dutch elm disease scare has turned into a Dutch elm disease reality,' says David Kearns with Kearnsy Consulting and Educational Services. Kearns says Saskatoon's urban canopy has become susceptible to certain diseases after years of drought or dry conditions. He adds another factor is the cost of removing a tree. Some trees can be removed for as little at a few hundred dollars while more mature trees could cost $7,000 to remove. Saskatoon began allowing people to dispose of elm wood for free in 2024, but Kearns says many people have a problem seeing a stressed tree in their backyard affecting an entire community or beyond. He says there are thousands of trees across the city that may have to be cut down if the disease continues to spread. 'It's not just a municipal problem, it's everybody's problem,' he said. 'I think a lot of people aren't seeing the connection between the tree in their backyard and the hundreds of thousands, if not tens of millions of dollars the City of Saskatoon is going to be on the hook for controlling this problem.' The city says American elm trees with Dutch elm disease can start showing symptoms as early as June. Typically the leaves will start to wilt and turn yellow, then curl and turn brown.
