The purpose of our study was to optimize the myocardial
T1 mapping technique using a composite RF pulse, which
is widely available in clinical practice. We evaluated
the effect of the composite RF pulse on T1 maps using
Saturation Recovery method with composite RF pulse by
phantom and human studies. We also evaluated T1 value of
cardiac amyloidosis patients. Our experiments showed
that a T1 mapping with SR method using composite RF
pulse provides more accurate quantification of T1
values. It may facilitate the detection of even the
smallest fibrosis with no contrast agent in
cardiomyopathy patients.
