Photon counting detector CTA for prostate artery embolization pre-procedure planning and intra-procedural guidance.
Article in CVIR endovascular, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundProstate artery embolization (PAE) requires a careful understanding of pelvic arterial anatomy and identifying prostatic artery variants. Pre-procedure CTA and intra-procedural cone beam CT are traditional means of planning and performing PAE, with the latter providing guidance for embolization. Photon counting detector (PCD) CT enables ultra-high spatial resolution (UHR) whole-body imaging. For PAE, we obtain a single UHR PCD CT arterial phase acquisition, which provides both detailed pre-procedure pelvic arterial anatomic information and a dataset for 2D (angiographic) to 3D (CTA) fusion for intra-procedural guidance during PAE using embolization guidance software in the angiography suite. CASE PRESENTATIONS: In six patients who underwent technically successful PAE via a left transradial approach, the pre-procedure diagnostic UHR pelvic PCD prostate CTA delineated bilateral prostatic artery origins and course in all cases, as confirmed with conventional angiograms. Further, registration of the UHR PCD CTA for embolization guidance was successful in all cases, augmenting vessel selection. No complication occurred.
conclusionUHR PCD CTA is a novel imaging technology that can provide detailed prostate arterial anatomic information for pre-procedure PAE planning. Further, this same UHR PCD CTA dataset can be used for intra-procedural embolization guidance using commercially available embolization guidance software.
