Myocardial T1 mapping, which is used to detect diffuse
fibrosis and quantify extracellular volumes, often
employs 8-10 mm 2D slice acquisitions. However, this
approach may be unsuited for accurate quantification of
small tissues samples. 3D T1 mapping is desirable, and a
FAN-type view ordering has recently been shown to
improve through-plane resolution over multiple
breath-holds. In this study, we propose a new view order
method called NINJA-STAR (or NJS), which allows
efficiently acquisition of 3D MRI k-space in a reduced
number of breath-holds, and examine this approach in
both phantom experiments and in-vivo.
