Unlocking boundless potential

For patients, clinicians and researchers alike, St. Joseph’s Health Care London’s new PET/CT is quickly 
living up to high expectations and helping to pave the way in making the impossible possible.

London Ontario – Ashmeet Gill had her first PET/CT scan shortly after being diagnosed with Hodgkin’s lymphoma, a
cancer of the body’s germ-fighting immune system. She was nervous. Claustrophobia is an issue for the young Stratford 
resident and the scan, necessary to determine if the cancer had spread beyond the lymph nodes in her neck, would take 
34 to 45 minutes, she was told. 

Wrapped in a sheet and tucked inside the tube of the PET/CT at St. Joseph’s Health Care London (St. Joseph’s), Ashmeet, 
then 24, steeled herself to remain calm. But near the end of the scan, a sense of panic set in.

“It was not pleasant but I endured it. I made it through.”

Ashmeet’s next PET/CT scan would be six months later, after six cycles of chemotherapy, to determine if the treatment 
had worked. She was terrified of another panic episode. By then, however, St. Joseph’s had a brand-new PET/CT –
Canada’s first, next generation, state-of-the-art Omni Legend PET/CT from GE HealthCare.

This time, Ashmeet’s scan took “barely 15 minutes or so,” she recalled. 

“I thought, seriously? I couldn’t believe I was done. I was so happy.”

With the very first patients scanned with St. Joseph’s new PET/CT machine, it was obvious the breakthrough technology 
was living up to high expectations. 

The machine is fast – decreasing the time it took for a scan from about 45 minutes on the older system to less than 14 –
head to toe. Patients are exposed to less radiation, and the ability to precisely detect disease and tiny abnormalities is 
outstanding.

“This is what we have been waiting for,” says Ting-Yim Lee, a pioneer in the use of machines like PET/CT to gather new, 
vital information about diseases. “St. Joseph’s new Omni Legend by GE HealthCare is answering the call for patients, 
clinicians and researchers alike.”

PET/CT is the medical ace in imaging for the assessment and treatment monitoring of cancer, neurodegenerative 
disorders, and metabolic and cardiovascular diseases. At St. Joseph’s, the possibilities of this technology took a giant 
leap forward in August 2023, thanks in part to the generosity of donors and a $1 million contribution from St. Joseph’s 
Health Care Foundation. With the arrival of the new system, St. Joseph’s is set to become Canada’s first national GE 
HealthCare centre of excellence in molecular imaging and theranostics. This two-pronged approach to diagnosing and 
treating cancers and other diseases merges molecular imaging with the use of radiopharmaceuticals to identify the 
location and extent of diseased tissues and selectively destroy the abnormal cells.

“The speed at which we can now do exams means significantly improved comfort for patients while the exceptional 
image quality changes the game in the hunt for cancerous lesions,” explains Ting, Director of PET/CT Research at Lawson 
Health Research Institute (Lawson) and medical physicist at St. Joseph’s Hospital. 

“For young adults undergoing repeat PET/CT exams due to their medical conditions, managing the radiation dose is 
critical,” explains Dr. Narinder Paul, Lawson scientist and Chief, Medical Imaging, at St. Joseph’s. “These individuals 
already face an elevated life-time risk of developing cancer from radiation, and this risk further increases with additional 
exposures.”

For older adults, the time it takes for the examination is also of great concern. Lying still for long periods can be a 
hardship due to pain from bone metastases or other conditions, and is a challenge for those who have dementia, are 
claustrophobic or experiencing other issues, adds Dr. Paul. 

“Reducing the exam time is a huge improvement in the patient experience for these individuals.” 

While patients hail the new PET/CT experience, clinicians and scientists are raving about the machine’s imaging prowess. 

The advanced AI-driven image formation technology now empowers the precise detection of cancer within lymph nodes 
and other anatomical structures, “achieving remarkable accuracy even for very small lesions,” says Dr. Paul. 

“The advantages we have seen so far are already impressive but what’s on the horizon in research and care – what we 
will be able to study and do – is even more exciting,” says Ting. 

In particular, the new PET/CT is expected to be the catalyst for ground-breaking clinical research for patients facing 
breast cancer, Alzheimer’s disease, prostate cancer, epilepsy and obesity. Scientific exploration in these areas is
currently being planned at St. Joseph’s that will pave the way for novel treatments, new, non-invasive ways to identify a 
patient’s risk of disease, the potential to clearly and painlessly view how treatment is working, and the ability to uncover 
the tiniest abnormalities at play when it comes to diseases and conditions.
