Intravascular magnetic resonance imaging (MRI) [PDF]

, 2014
This chapter discusses the advantages of using MRI in intravascular operations. Beginning with a brief explanation of some sample intravascular MR operations, the chapter goes on to outline the visualization problem of catheters under MRI. Some of the fundamental catheter coil designs are shown and a range of imaging techniques for catheter tracking ...

An imbalance between functional segregation and integration in patients with pontine stroke: A dynamic functional network connectivity study

NeuroImage: Clinical, 2020
Background: Previous studies on brain functional connectivity have revealed the neural physiopathology in patients with pontine stroke (PS). However, those studies focused only on the static features of intrinsic fluctuations, rather than on the time ...
