This
study aimed to develop a new method enabling a fast time-resolved cine 2D and
cine 3D (4D) black blood imaging of mouse heart. This sequence has been
applied to Manganese-Enhancement MRI (MEMRI) studies i.e. with Mn2+
infusion to improve contrast. This new method provided time- and
space-resolved 3D images, respectively (200 m) 3 and one image
every 12 ms, for the first time within 30 minutes only. Lastly, associated to
manganese infusion, this sequence appeared to be particularly adequate for
studying cardiac pathologies such as ischemia on animal models.
