In Conversation with: Dr. Christopher Fung
With diagnostic medicine rapidly advancing, the pursuit for more accessible and precise imaging modalities remains a primary objective for clinicians worldwide. Dr. Christopher Fung, a distinguished radiologist at MIC Medical Imaging and a leading clinical researcher, shared insights into a transformative era for prostate cancer diagnosis and the broader field of interventional radiology.
A key highlight of the conversation was the recent global recognition of a landmark study co-authored by Dr. Fung and urologist Dr. Adam Kinnaird. Their research received the prestigious Imaging Vision Award from the European Association of Urology, honoring it as the most impactful advancement in urological imaging worldwide over the past year. This achievement represents a proud moment for Edmonton’s medical community.

Rethinking the Role of MRI in Prostate Cancer Detection
The study, published in the Journal of the American Medical Association (JAMA), involved a collaboration across 19 international institutions and eight countries. The core finding of this randomized controlled trial challenged long-standing clinical assumptions by demonstrating that high-resolution micro-ultrasound is not inferior to Magnetic Resonance Imaging (MRI) in the detection of clinically significant prostate cancer.
MRI remains the gold standard, yet its implementation is often hindered by the realities of Canada’s healthcare model. Resource scarcity and long wait lists, combined with patient-specific limitations like claustrophobia or implanted devices, create significant impediments to timely diagnosis. Micro-ultrasound offers a versatile alternative, utilizing ultra-high-frequency wavelengths to visualize the anatomy of the prostate with a level of resolution previously unavailable in traditional ultrasound.
The implications of this research offer a pragmatic solution to enhance patient care and diagnostic accuracy. By demonstrating that micro-ultrasound can achieve consistency with MRI, the study advocates for a more flexible diagnostic framework, allowing patients to receive high-level care in an office setting, eliminating many of the logistical barriers associated with a large-bore magnet.
Dr. Fung emphasized that this technology is not intended to entirely replace MRI, but rather to complement it. In the future, micro-ultrasound may be utilized for the active surveillance of low-grade disease, allowing clinicians to monitor patients closely without occupying valuable MRI slots that could be used for other urgent diagnostic needs.
Advancing Care Through Interventional Radiology
Beyond his contributions to prostate research, Dr. Fung discussed the vital role of interventional radiology in modern patient care. By leveraging real-time imaging modalities such as CT and ultrasound, radiologists can perform complex biopsies and localized treatments that previously required invasive surgical intervention. This shift toward minimally invasive procedures significantly reduces recovery times, allowing patients to enter treatment pathways more quickly.
Dr. Fung highlighted his leadership role in developing national appropriateness guidelines for the Canadian Association of Radiologists. These guidelines are essential for primary care physicians, providing them with the necessary “clinical vignettes” to determine which imaging tests are the most appropriate for a specific patient case, ensuring that every test performed is both necessary and effective.
Dr. Fung and his team are already pivoting toward the next frontier: Prostate-Specific Membrane Antigen (PSMA) PET imaging. This advanced technology is identifying metastatic disease in the bones and lymph nodes that might be missed by conventional scans.
Curiosity as the Driver for Clinical Innovation
When reflecting on the trajectory of his career and the evolution of the field, Dr. Fung noted that the most critical asset for any medical professional is an unwavering sense of curiosity. It is this commitment to questioning established norms and seeking better evidence that drives clinical innovation and, ultimately, ensures the highest standard of care for patients across the province and the country.
