Abstract
This review gives a survey on the use and applications of technetium-94m (94mTc) as a non-conventional positron emission tomography (PET) radionuclide for molecular imaging. The first part of this review describes the production and processing of 94mTc. The second part covers basic concepts of technetium coordination chemistry with a special focus on the synthesis of 94mTc-labeled compounds for molecular imaging purposes. The review concludes with a summary and an outlook on the prospects of using 94mTc in the field of PET chemistry and molecular imaging. Keywords: Technetium-94m, positron emission tomography, radiopharmaceuticals, molecular imaging, 94mTc Production, Thermochromatographic Separation, Solvent Extraction, PET Imaging, COORDINATION CHEMISTRY

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
