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 evaluate single- and dual-band pulse modules for suppressing extra-cardiac signal in cardiac MRI, and test their applicability for time-efficient imaging with reduced FOV in myocardial

methodsOuter Volume Suppression (OVS) was implemented using two regional saturation slabs, along the phase-encoding direction. Different Amplitude-Modulated (AM) and Amplitude-Frequency-Modulated (AM-FM) pulses were explored. AM sinc and AM-FM Hyperbolic Secant (HS) pulses, as single- (S:1b and HS:1b) and dual-band (S:2b and HS:2b) versions, were chosen for full evaluation. Pulses were individually optimized for minimal residual signal and optimal suppression-band profiles. Pulse performance was assessed through simulations and phantom experiments, and evaluated in seven healthy subjects using residual signal and quantitative myocardial

resultsIn simulations, optimized HS pulses demonstrated superior suppression-band profile homogeneity and

conclusionAM-FM pulses achieved robust suppression of extra-cardiac signals, with dual-band implementations minimizing suppression-band differences. This can enable artifact-free rFOV imaging, for improved image quality in myocardial
