[Virtual histopathology of the pancreas: 3D insights using synchrotron-based imaging].
Article in Pathologie (Heidelberg, Germany), 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 histopathology faces methodological limitations when assessing complex three-dimensional tissue architectures. In particular, for heterogeneous tissues such as the pancreas or in complex tissue pathologies, restriction to two-dimensional sections hampers comprehensive recognition of morphological features.
objectiveThis study aims to demonstrate the potential of synchrotron-based phase-contrast imaging (SRµCT) as a tool for high-resolution visualization of pancreatic tissue. Three representative case examples were analyzed to capture morphological parameters volumetrically and correlate them with immunohistochemical marker profiles. MATERIALS AND
methodsTissue cores from formalin-fixed, paraffin-embedded human pancreatic samples were volumetrically assessed using SRµCT. The investigated material was further processed as microarrays. Serial sections and immunohistochemical stains were correlated with the 3D datasets.
resultsSRµCT enabled detailed spatial visualization of functional compartments and neoplastic infiltration patterns. Non-neoplastic tissue revealed distinct morphological compartments. A well-differentiated neuroendocrine tumor exhibited trabecular architecture, whereas ductal adenocarcinoma displayed infiltrative growth with diffuse, heterogeneous architecture, irregular duct formations and stromal desmoplasia. Virtual slicing permitted orientation-independent analyses. Correlation with immunohistochemical profiles validated the morphofunctional findings.
conclusionSRµCT is a sensitive, non-invasive technique providing label-free 3D insights into pancreatic architecture. It opens new perspectives for research, teaching, and potentially advanced diagnostic applications.
