This is truly remarkable news to see the recent publication made by the Canadian Association of Nuclear Medicine (please see below for article and published guidelines).  As noted, these technical guidelines are the first published by any expert society globally in a decade.  I am very proud to work with some of the medical specialists and CEO’s who were responsible for conducting this research dealing with BRAIN SPECT.

BRAIN SPECT – Medically Recognizable to Diagnose TBI

NEWS, July 16, 2021:  We are proud to announce a landmark decision recently published by The Canadian Association of Nuclear Medicine (CANM) ratifying and endorsing guidelines for Brain Perfusion Single Photon Emission Computed Tomography (SPECT).

Read Published Guidelines:  CANM GUIDELINES

Several of our experts are responsible for and authored this extensive research.

Congratulations to all the authors:

Phill F Cohen md FRCP(c) ABNM, Robert Tarzwell, MD, FRCPC, Leonard Numerow MD FRCP(C), Yin-Hui Siow, MD, FRCPC, John M Uszler, MD, MS, Dan G.

Of interest to personal injury litigants, the CANM, Canada’s premier expert body in nuclear medicine, has listed under indications, section A.3 Evaluation of traumatic brain injury. The Guideline states, “SPECT has shown perfusion abnormalities in traumatic brain injury despite normal morphology, and results are considered to have a prognostic value for persistence of neuropsychological sequelae.”

In plain language, the CANM accepts that brain perfusion SPECT is able to demonstrate the presence of TBI even in the setting of normal CT or MRI scans. Furthermore, results are considered predictive of whether psychological and cognitive problems will persist over time.

The CANM has not previously published guidelines for this technique, and this publication also represents the first update to these technical guidelines published by any expert society globally in a decade. Therefore, the Canadian Guidelines can now be considered the most scientifically up to date in the world.  The CANM now joins the European Association of Nuclear Medicine (EANM) in accepting the validity of brain perfusion SPECT in the diagnosis and prognosis of traumatic brain injury, even in the setting of normal CT or MRI.
