Editor’s Choice February 2015 (2 of 3) FLAIR images from over 140 patients with acute MCA infarctions were analyzed and compared with images used to estimate the ischemic penumbra. A FLAIR-DWI mismatch was seen in 72% of patients and the
Fellows’ Journal Club January 2015 (2 of 3) Using CT or DWI, the authors categorized percentages of insular ribbon infarctions as less or more than 50% and correlated these with clinical outcomes. Only insular ribbon involvement greater than 50% and
Fellows’ Journal Club November 2014 (1 of 3) The benefit of thrombolytic therapy was assessed in 54 patients with a mismatch between infarct core as seen on DWI and penumbra as seen on SWI. Favorable outcomes were significantly higher in
Fellows’ Journal Club September 2014 (3 of 3) HASTE DWI was used to examine 16 patients before cholesteatoma surgery and the findings were compared with those seen intraoperatively. HASTE DWI showed 90% sensitivity, 100% specificity, 100% positive predictive value, and
Fellows’ Journal Club April 2014 (1 of 3) The implications of the reversal of DWI abnormalities in patients with TIA and minor strokes were assessed. Patients were imaged within 24 hours of symptoms and followed for 3 months and baseline
abscesses dwi We are back from RSNA and it is time to post a new educational activity in our blog. This presentation, by one of our previous neuroradiology fellows, addresses the typical and atypical findings and utility of DWI in
A young man presented with ataxia. Brain contrast enhanced MRI was done including DWI and perfusion. T2WI showed a mixed intensity lesion in the inferior right cerebellar hemisphere which contained some “dark stripes”. DWI ADC map show restricted diffusion centrally.
I will like to know if someone can help me with some doubts I have regarding ADCs. 1. I have a sample with some ADC values obtained in 1,5 T and others obtained in 3T ( same b value). Can I
Here’s another case for the value of DWI for head and neck lesions. This patient had left central retinal artery occlusion and acute ischemic optic neuropathy. There is restricted diffusion in the anterior left optic nerve which is much more
