Division of Nuclear Medicine

Celebrate with the Division of Nuclear Medicine as it dedicates a state-of-the-art reading room in honour of Dr. Laurent Dinh.

Dr. Dinh was a longstanding member of the Division of Nuclear Medicine who passed away in February 2015 after a brief illness. Dr. Dinh was a consummate clinician, nuclear medicine training program director, generous colleague and most-admired friend at The Ottawa Hospital. In addition to his role in Nuclear Medicine, Dr. Dinh faithfully served as Chair of the Radiation Safety Committee at The Ottawa Hospital for many years.

Through generous donations from colleagues, the Nuclear Medicine Reading Room at the General Campus (Room M1499) has been redesigned and updated, incorporating various electronic teaching aids, and has been designated as “Dr. Laurent Dinh Educational Reading Room”. Colleagues and friends are respectfully invited to the dedication of this facility which will take place on Tuesday, March 28th at 4:00 pm.

There will be a brief ceremony followed by refreshments and a celebration of Dr. Dinh’s enduring contribution to education and patient care at The Ottawa Hospital.

The Division of Nuclear Medicine at The Ottawa Hospital is geographically located at all three campuses; General, Civic and Riverside. The Division which is the largest in the region provides a full range of Nuclear Medicine services to Eastern Ontario and Western Quebec with a catchment population of approximately 1.2 million people.

Clinical Programs

Nuclear Medicine at the General Campus includes an oncologic PET imaging program, general nuclear medicine with bone and pulmonary ventilation perfusion scans as well as cardiac imaging services. The Civic program includes general nuclear medicine. Bone mineral densitometry service is provided at the Riverside campus.

The 3 clinical sites are networked internally at each site and to each other using a newly updated Hermes (processing and archiving) network. The Heart Institute is also linked to the 3 Nuclear Medicine sites providing redundancy across the entire NM network. Nuclear Medicine scans are exported to The Ottawa Hospital’s corporate Picture Archive Communications System (PACS). Physician dictation in Nuclear Medicine is supported by voice recognition technology. The Hospital implemented this technology in 2006 using Nuance’s Powerscribe VR system.

Radiochemistry service is provided through an onsite commercial radiopharmacy excepting FDG, which is supplied by CPDC. Novel PET radiopharmaceuticals are available through the University of Ottawa Heart Institute cyclotron program. The Nuclear Medicine clinical program at all 3 campuses is accredited by the Intersocietal Commission for Accreditation of Nuclear Medicine Laboratories (ICANL).


Postgraduate Nuclear Medicine Residency Program is approved by the Royal College of Physicians and Surgeons of Canada. Trainees rotate through the General and the Civic campuses and also through the University of Ottawa Heart Institute Nuclear Cardiology and Cardiac PET programs. Interuniversity agreements are in place with the University of Toronto and the McGill University for training in pediatric nuclear medicine and PET-CT respectively.


Ongoing clinical research at The Ottawa Hospital includes tomographic imaging with bone and ventilation perfusion scans.
