Photon-Counting Computed Tomography for In-Stent Occlusion: Lumen Visualization and Myocardial Viability.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundConventional computed tomography evaluation of coronary stents is frequently limited by metal blooming artifacts. Ultra-high-resolution photon-counting detector computed tomography (PCCT) improves visualization of the internal vessel lumen and allows myocardial tissue characterization within a single noninvasive acquisition. CASE SUMMARY: A 58-year-old man with prior right coronary artery stenting presented with crescendo chest pain despite optimal therapy. Ultra-high-resolution PCCT demonstrated chronic total in-stent occlusion and robust left anterior descending artery-to-right coronary artery collaterals. Spectral iodine mapping identified a nonviable transmural scar, supporting conservative management and avoiding unnecessary high-risk revascularization. DISCUSSION: Recent studies report high concordance between PCCT and magnetic resonance imaging for late enhancement. This case interests readers by demonstrating PCCT's "one-stop-shop" capability to surpass traditional imaging barriers, providing the detailed evidence necessary to optimize high-stakes clinical decisions. TAKE-HOME MESSAGE: PCCT may improve diagnostic workflows and enhance precision for the management of complex coronary artery disease.
