Renal T2-weighted turbo-spin-echo imaging with BLADE at 3.0 Tesla: initial experience.
The purpose of this study is to evaluate the feasibility and image quality of multishot T2-weighted (T2w) renal morphologic imaging based on the acquisition of rotating rectangular strips of k-space data after successive radiofrequency excitations (BLADE technique). ⋯ The SNR did not show significant differences. The overall image quality was rated significantly higher for the T2w-BLADE (P < 0.05). Equally, the presence of disturbing artifacts and the sharpness was ranked significantly better for T2w-BLADE than for the T2w-TSE (P < 0.05). The T2w-BLADE was the preferred sequence in 59% of all cases, the T2w-TSE in 9%.T2w-BLADE sequences seem to be superior for the depiction of the kidneys at 3.0T, particularly due to the decreased number of artifacts and sharper delineation of the organs.

Stimulated-echo acquisition mode (STEAM) MRI for black-blood delayed hyperenhanced myocardial imaging.
To develop a breathhold method for black-blood viability imaging of the heart that may facilitate identifying the endocardial border. ⋯ The STEAM black-blood property allows for better delineation of the blood-infarct border, which would enhance the fast and accurate measurement of infarct size.
