Contrast Enhancement of the Olfactory Recess Using Heavily T2-Weighted 3D Fluid-Attenuated Inversion Recovery Imaging (FLAIR).

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.
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
Purpose This study aimed to assess the contrast enhancement of the olfactory recess using heavily T2-weighted 3D fluid-attenuated inversion recovery (FLAIR) imaging after intravenous gadolinium administration. Methods This retrospective study included 35 patients. The overall contrast enhancement of the bilateral olfactory recess between the precontrast, postcontrast, and 4-h delayed postcontrast T2-weighted 3D FLAIR images were subjectively evaluated. In addition, serial changes in signal intensity in the olfactory recess and other structures (other cerebrospinal fluid spaces and the pons) were objectively assessed. Results Subjective analysis showed that contrast enhancement of the olfactory recess was observed in 61 (right: 28, left: 33) and 67 (right: 32, left: 35) of 70 ears from 35 patients on postcontrast and 4-h delayed postcontrast T2-weighted 3D FLAIR images, respectively. In the objective analysis, the relative enhancement of the olfactory recess was the highest for 4-h delayed postcontrast images, followed by postcontrast images. This enhancement pattern was similar to that of the cerebrospinal fluid spaces surrounding the other cranial nerves. Conclusion The olfactory recess was enhanced using T2-weighted 3D FLAIR imaging. These findings may provide novel insights into cerebrospinal fluid and solute dynamics and may contribute to optimizing imaging protocols for evaluating related neurological disorders.
