Richard Farb

Richard Farb, MD, FRCPC

Site Director, Sinai Health

Dr. Farb is an interventional and diagnostic neuroradiologist specializing in the treatment of patients with brain vascular disorders, especially brain aneurysms, carotid artery disease and acute stroke. His research interests include stroke imaging and neurovascular MR angiographic techniques.

He is an Associate Professor with the Department of Medical Imaging at UofT, and a Clinician Investigator with the Krembil Research Institute, UHN.

Recent Publications

  • The presence of pachymeningeal hyperintensity on non-contrast flair imaging in patients with spontaneous intracranial hypotension

    CONCLUSION: Where present, diffuse pachymeningeal hyperintensity can be accurately identified on a non-contrast FLAIR sequence in patients with […]

  • Minimally invasive surgery for spinal cerebrospinal fluid-venous fistula ligation: patient series

    BACKGROUND: Cerebrospinal fluid-venous fistulas (CVFs) may cause cerebrospinal fluid leaks resulting in spontaneous intracranial hypotension (SIH). […]

  • Spontaneous intracranial hypotension: searching for the CSF leak

    Spontaneous intracranial hypotension is caused by loss of CSF at the level of the spine. The most frequent symptom of this disorder is orthostatic […]

  • Assessment of Discrepancies Between Follow-up Infarct Volume and 90-Day Outcomes Among Patients With Ischemic Stroke Who Received Endovascular Therapy

    CONCLUSIONS AND RELEVANCE: In this study, discrepancies between functional outcome and post-EVT infarct volume were associated with differences in […]

  • Spinal Longitudinal Epidural Collections in Intracranial Hypotension

  • Radial vs. Femoral Artery Access for Procedural Success in Diagnostic Cerebral Angiography : A Randomized Clinical Trial

    CONCLUSION: Radial artery access is non-inferior to femoral artery access for procedural success in cerebral angiography. A large multicenter trial […]

  • Digital Subtraction Myelography is Associated with Less Radiation Dose than CT-based Techniques

    CONCLUSION: The radiation dose with DSM appears to be significantly lower than that of CTM (p = 0.0005), when looking at CTM doses both from our […]

  • Efficacy and safety of nerinetide for the treatment of acute ischaemic stroke (ESCAPE-NA1): a multicentre, double-blind, randomised controlled trial

    BACKGROUND: Nerinetide, an eicosapeptide that interferes with post-synaptic density protein 95, is a neuroprotectant that is effective in preclinical […]

  • Hydrocephalus and CSF Disorders

    Structural and functional neuroimaging techniques play an essential role for understanding the hydrodynamics of cerebrospinal (CSF) flow and on the […]

  • Spontaneous spinal CSF-venous fistulas associated with venous/venolymphatic vascular malformations: report of 3 cases

    Spontaneous CSF-venous fistulas may be present in up to one-fourth of patients with spontaneous intracranial hypotension. This is a recently […]

  • Lateral decubitus digital subtraction myelography to identify spinal CSF-venous fistulas in spontaneous intracranial hypotension

    CONCLUSIONS: Among SIH patients in whom conventional spinal imaging showed no evidence of a CSF leak, DSM in the lateral decubitus position […]

  • Management of multiple meningiomas

    OBJECTIVE Multiple meningiomas account for 1%-10% of meningiomas. This study describes epidemiological aspects of the disease and its management, […]

  • Spontaneous Intracranial Hypotension: A Review and Introduction of an Algorithm For Management

    BACKGROUND: Spontaneous intracranial hypotension (SIH) is a condition of low cerebrospinal fluid volume and pressure caused by a leak of […]

  • Long-Term Results of Stenting versus Endarterectomy for Carotid-Artery Stenosis

    CONCLUSIONS: Over 10 years of follow-up, we did not find a significant difference between patients who underwent stenting and those who underwent […]

  • Mediators of the Age Effect in the Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST)

    CONCLUSIONS: Plaque length seems to be in the pathway between older age and higher risk of S+D among carotid artery stenting-treated patients, but it […]

  • Confusion between bitemporal hemianopia and cecocentral scotoma: reply

    No abstract

  • The accuracy and utility of contrast-enhanced MR angiography for localization of spinal dural arteriovenous fistulas: the Toronto experience

    CONCLUSIONS: CE-MRA is a useful non-invasive examination for the detection and localization of SDAVF. CE-MRA facilitates but does not replace DSA as […]

  • Optic chiasm involvement on MRI with ethambutol-induced bitemporal hemianopia

    While ethambutol optic neuropathy usually causes central or cecocentral scotomas, bitemporal visual field defects also have been reported. The […]

  • Captured Macro-embolus of Fractured Atheromatous Plaque by the Embolic Protection Device during Carotid Stent Assisted Angioplasty

    The authors present a case in which macro-embolus from the ruptured atheromatous plaque developed during carotid artery stenting (CAS). A 63-year-old […]

  • Restenosis after carotid artery stenting and endarterectomy: a secondary analysis of CREST, a randomised controlled trial

    BACKGROUND: In the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), the composite primary endpoint of stroke, myocardial […]

  • Vessel wall MRI to differentiate between reversible cerebral vasoconstriction syndrome and central nervous system vasculitis: preliminary results

    CONCLUSIONS: Preliminary results suggest that high-resolution contrast-enhanced vessel wall MRI may enable differentiation between reversible […]
