The evaluation of non-contrast MRA using a modified balanced steady state free precession technique in the follow-up of renal artery aneurysm after embolotherapy.

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
purposeTo evaluate the feasibility and clinical utility of non-contrast magnetic resonance angiography (NC-MRA) using a modified balanced steady-state free precession (b-SSFP) technique combined with arterial spin labeling (ASL) for post-embolotherapy follow-up of renal artery aneurysms (RAAs), with digital subtraction angiography (DSA) as the reference standard.
methodA total of 57 patients with RAAs underwent embolotherapy between June 2013 and July 2024. Among them, 15 RAAs from 14 patients underwent post-embolization surveillance with the NC-MRA and DSA. NC-MRA was performed at 12 months after coil embolization, followed by DSA. On NC-MRA images, complete occlusion is indicated by the absence of high signal within the aneurysm, whereas on DSA images, complete occlusion is defined as the absence of contrast enhancement within the aneurysm. We compare the NC-MRA and DSA results for each aneurysm during follow-up.
resultsOf the 15 aneurysms, 12 achieved complete occlusion and 3 exhibited incomplete occlusion. There was no aneurysmal growth, and no adverse events such as rupture or renal infarction occurred. We acquired 15 groups of follow-up MRA and DSA images, and the results were in perfect concordance.
conclusionThe NC-MRA using the modified b-SSFP combined with ASL shows good agreement with DSA in assessing recanalization of RAAs after embolotherapy and may serve as a reliable, non-invasive follow-up modality.
