Neurocysticercosis (NCC) is a common cause of morbidity in manydeveloping countries and a common cause of seizure disorder in children and adults. The 4 stages of NCC are vesicular, vesicular colloidal, granular nodular, and nodular calcified.1 The appearance on MR imaging would depend on the stage of the disease. Most commonly, NCC presents as isohypointense lesions on T1-weighted MR imaging. To our … Continue reading >>

Brachial Plexus MRI Protocol
Fall is upon us and so is the lecturing season! Like years before, this Fall I will be giving my brachial plexus lecture several times and the most commonly asked question by the audience is: “where can I get your MRI protocol?” For this reason I am posting it here. Posting of protocols seems to gather considerable attention; Dr. Wiggins post on MRI and CT protocols has been viewed over 1900 times! Caveats regarding this post: our BP protocol was designed to satisfy the needs of our clinicians here at UNC, your referring physicians may be expecting … Continue reading >>

Using DTI-MRI in Geron’s Phase I Clinical Trial
What do you think about the use of DTI-MRI for tracking the progress of therapy in Geron’s upcoming Phase I clinical trial? DTI measures (transverse and longitudinal diffusivity) in some rodent models of spinal cord injury have shown correlations with myelination and axonal integrity. If the intraspinally injected oligodendrocyte progenitor cells are indeed remyelinating damaged axons, then perhaps tracking patients with non-invasive DTI-MRI could allow the investigators to better assess the outcomes of their intervention?… Continue reading >>
