BACKGROUND AND PURPOSE: Preoperative identification of plaque vulnerability may allow improved risk stratification for patients considered for carotid endarterectomy. The present study aimed to determine which plaque imaging technique, cardiac-gated black-blood fast spin-echo, magnetization-prepared

Transcranial Doppler and diffusion-weighted magnetic resonance evaluation of cerebral embolization occurring during transfemoral carotid stenting with proximal flow blockage.

Palombo G1, Stella N, Fantozzi C, Bozzao A, Taurino M.
The Journal of cardiovascular surgery.J Cardiovasc Surg (Torino).2016 Feb;57(1):52-7.
BACKGROUND: Transfemoral carotid artery stenting (CAS) with endovascular proximal flow blockage is deemed able to reduce the cerebral embolization observed during filter-protected CAS. We evaluated clinical outcome and intraoperative embolization rates, measured by diffusion-weighted magnetic resona

Lupus.Lupus.2016 Feb;25(2):193-8. doi: 10.1177/0961203315608256. Epub 2015 Sep 23.
OBJECTIVES: The objectives of this report are to assess the occurrence of microembolic signals (MES) detected by transcranial Doppler ultrasound (TCD) in systemic lupus erythematosus (SLE) patients with (NPSLE) and without (SLE) neuropsychiatric involvement, and to verify the correlation between MES
