1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeTo demonstrate further acceleration of spin echo MRI by combining the simultaneous multi-slice approach with the recently introduced patterned multislice excitation (PME) technique and evaluate application for rapid diffusion-weighted MRI. THEORY AND

methodsImplementation at 3T involved the design of RF pulses simultaneously acting on four separate slices within hardware limits on peak amplitude. This was accomplished by time-shifted sub-pulses and a dedicated switching scheme of the slice-select gradient. The new technique was evaluated on two clinical MRI systems with differing maximum gradient strength.

resultsFour-fold acceleration was successfully achieved by combining PME with rate-2 SMS. Within fixed measurement time, the proposed approach allows increased averaging or more elaborate sampling of diffusion tensor space. Depending on implementation, gains in SNR per unit time were modest or small, which is attributed to out-of-slice saturation effects of the RF pulses.

conclusionCombination of PME with SMS-2 for further acceleration of diffusion imaging is feasible at 3T.
