Abstract
Diffusion weighted imaging (DWI) is a promising magnetic resonanceimaging (MRI) modality with wide applications in diagnosisof different types of diseases such as prostate cancer. DWI providesa large amount of imaging data which often makes it difficultto interpret accurately, mainly due to the fact that much of informationin diffusion imaging cannot be deciphered by human expertsalone. Computational diffusion MRI (CD-MRI) aims to leveragecomputational means to generate imagery from diffusion signalswhich are easier to interpret by human experts. Recently, anew CD-MRI modality called correlated diffusion imaging (CDI) hasbeen proposed which takes advantage of the joint correlation of diffusionsignal attenuation across multiple gradient pulse strengthsand timings to improve the separability of cancerous and healthytissues. In this paper, we propose a new CD-MRI modality calledSparse CDI (sCDI) where an optimally sparse subset of diffusionsignals contributes to the formation of the final diffusion signal leadingto further separation of cancerous and healthy tissue in prostategland compared to CDI and conventional DWI.

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 it
