Deep-learning reconstruction of the prostate improves image quality and acquisition time in T2-weighted imaging.

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
We compared the qualitative and quantitative quality of prostate conventional T2-weighted imaging and T2-weighted imaging with deep-learning reconstruction. Patients with suspected prostate cancer undergoing magnetic resonance imaging between April 2022 and June 2023 were included. Quantitative analysis was performed to determine the signal-to-noise and contrast ratios of the perirectal fat tissue, internal obturator muscle, and pubic tubercle. Eight periprostatic anatomical structures, overall image quality, and motion artifacts were evaluated by two radiologists using 5- or 4-point scales. Qualitative analysis results were compared to determine the agreement between the two radiologists. In total, 106 patients (mean age: 71 ± 8.3 years; 106 men) were included in this study. The acquisition time for conventional T2-weighted imaging and T2-weighted imaging with deep-learning reconstruction was 4 min and 16 s and 2 min and 12 s, respectively. The signal-to-noise ratio of the perirectal fat tissue and internal obturator muscle and contrast ratio of fat/muscle and bone/muscle determined via T2-weighted imaging with deep-learning reconstruction were significantly superior to those determined via conventional T2-weighted imaging (both
