Abstract
Conventional two-dimensional and three-dimensional single photon emission computed tomography and positron emission tomography imaging tools and specific inhaled radiotracers allow accurate and reliable measurements of drug delivery to the lung. Pharmacokinetics and patterns of drug distribution can be monitored over time. In addition, physiologic measurements of ventilation, perfusion, mucociliary clearance, inflammation, and respiratory absorption can be determined using imaging; the results correlate with "black-box" outcomes (for example, spirometry, airway responsiveness, and inflammatory markers in sputum, and bronchoalveolar lavage fluid), providing an indication of the disease state in situ and the effectiveness of therapeutic and other interventions on these critical lung functions. Imaging is widely used in drug discovery. Screening of new drugs using animal models and specifically molecular imaging before human studies is an approach used extensively by the pharmaceutical industry. Topical drug delivery to the lung remains the route of choice for administering respiratory therapies; recently, inhaled therapies have been formulated to gain access to the systemic circulation via the distal lung. Imaging provides a means of validating drug delivery to the site of action in the lung and of measuring the resulting pharmacokinetics of these therapies. No other tool or test provides this type of visual detail supported by numerical information related to a specific drug molecule.

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
