Abstract
Magnetic resonance direct thrombus imaging (MRDTI) is a new application of magnetic resonance technology that capitalizes on the fact that thrombus is associated with a substantial reduction in T1 (spin-lattice relaxation time). A T1-weighted magnetization-prepared 3-dimensional gradient-echo sequence is used with a selective water-excitation radiofrequency pulse to abolish fat signal. The effective inversion time is chosen to null the blood signal, so that thrombus shows up as a …
