Tissue clearing techniques for three‐dimensional optical imaging of intact human prostate and correlations with multi‐parametric MRI
Bibliographic record
Abstract
Abstract Background Tissue clearing technologies have enabled remarkable advancements for in situ characterization of tissues and exploration of the three‐dimensional (3D) relationships between cells, however, these studies have predominantly been performed in non‐human tissues and correlative assessment with clinical imaging has yet to be explored. We sought to evaluate the feasibility of tissue clearing technologies for 3D imaging of intact human prostate and the mapping of structurally and molecularly preserved pathology data with multi‐parametric volumetric MR imaging (mpMRI). Methods Whole‐mount prostates were processed with either hydrogel‐based CLARITY or solvent‐based iDISCO. The samples were stained with a nuclear dye or fluorescently labeled with antibodies against androgen receptor, alpha‐methylacyl coenzyme‐A racemase, or p63, and then imaged with 3D confocal microscopy. The apparent diffusion coefficient and K trans maps were computed from preoperative mpMRI. Results Quantitative analysis of cleared normal and tumor prostate tissue volumes displayed differences in 3D tissue architecture, marker‐specific cell staining, and cell densities that were significantly correlated with mpMRI measurements in this initial, pilot cohort. Conclusions 3D imaging of human prostate volumes following tissue clearing is a feasible technique for quantitative radiology–pathology correlation analysis with mpMRI and provides an opportunity to explore functional relationships between cellular structures and cross‐sectional clinical imaging.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
