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

objectiveTo explore the value of the united imaging compressed sensing with radial acquisition (uCSR) in liver dynamic contrast-enhanced examinations for elderly patients with malignancy.

methodsHundred patients aged 65 years or over were randomly divided into two groups: 50 patients underwent liver dynamic contrast-enhanced scanning using the uCSR sequence during free breathing, and 50 patients underwent scanning using the three-dimensional volume interpolated breath-hold examination (3D-VIBE) sequence while holding breath. Two radiologists independently and subjectively evaluated the overall image quality and image artifacts with a five-point scale. Concurrently, two technologists measured the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the arterial, portal venous and delay phase images in both groups.

resultsuCSR has superior overall image-quality and image-artifact scores (z = 2.342, p = 0.019; z = 2.105, p = 0.035). The 3D-VIBE images of the arterial phase have higher SNR than uCSR (t = 4.988, p = 0.000), with no significant difference in the CNR (z = 0.676, p = 0.499). In the portal venous phase, the SNR and CNR of the 3D-VIBE images are superior to those of uCSR (z = 5.674, p = 0.000; t = 3.638, p = 0.000). In the delay phase, the SNR of the 3D-VIBE is slightly better than the uCSR (t = 5.471, p = 0.000), and the CNR shows no significant difference (z = 1.258, p = 0.208).

conclusionuCSR can be used as a method for liver dynamic contrast-enhanced scans in elderly patients with malignancy. It can improve patient comfort and reduce the failure rate of scans. CRITICAL RELEVANCE STATEMENT: Our findings suggested that uCSR can be used for liver dynamic contrast-enhanced scans in elderly patients with malignancy, this preliminary study provided basis for it. KEY POINTS: The uCSR can suppress the impact of respiratory motion artifacts on images. The UCSR can perform dynamic enhanced scanning of the liver under free breathing dynamics. The uCSR is suitable for dynamic contrast-enhanced MR imaging of the liver in elderly patients with malignancy.
