1. 1. Detecting Cardiac Pulsatility and Respiration using Multiband fMRI

   University essay from Umeå universitet/Institutionen för fysik

   Author : Joakim Jonsson; [2018]
   Keywords : fMRI; multiband; cardiac pulsation; respiration; correlation analysis; neuroimaging;

   Abstract : Purpose: Arterial stiffening poses an increased risk of cerebrovascular diseases, cognitive impairments, and even dementia as cardiac pulsations reach further into the brain causing white matter hyperintensities and microbleeds. Therefore it is of interest to obtain methods to estimate and map cardiac related pulsatility in the brain. READ MORE
