[Usefulness of short inversion time inversion recovery-low B diffusion weighted imaging after pouring in gadolinium- ethoxybenzyl-diethylene-triaminepentaacetic acid].

Diffusion weighted imaging (DWI) using a low b value for examination of the body is not common, so we examined its usefulness. Phantom experiments were performed in which I changed the length of the echo time (TE), with and without short inversion time inversion recovery (STIR). The signal intensity of each phantom was reduced by using a longer TE or by combination with STIR, but contrast was improved.

[Imaging characteristics of two-dimensional spin echo T₁-weighted image in carotid artery plaque].

Recently, T₁ weighted image (T₁WI) has proven to be useful for diagnosing carotid plaque. This time, the image parameter of two-dimensional spin echo (2D SE) T₁WI was examined. Phantoms that imitated muscle and carotid plaque were made.
