Abstract
BACKGROUND: Ferumoxytol is a safe and effective parenteral therapy used for the treatment of iron deficiency anaemia that has recently been approved for use in North America and in Europe. METHODS: Ferumoxytol consists of a superparamagnetic iron oxide (SPIO) core, which causes T1, T2 and T2* shortening effects, and a carbohydrate shell, which results in a prolonged intravascular half life. RESULTS: These properties are under-reported and not well recognised. They can interfere with MRI interpretation, potentially masking enhancement and rendering examinations non-diagnostic or simulating pathologic disease states. Both radiologists and non-radiologist physicians must consider the potential interaction of ferumoxytol with MRI when interpreting and prescribing MRI examinations in their patients. MAIN MESSAGES: • Ferumoxytol has recently been approved for the treatment of iron deficiency anaemia. • Ferumoxytol is a small iron oxide particle with prolonged intravascular half life and T1, T2 and T2* shortening effects. • Administration of ferumoxytol can mask enhancement, rendering MRI studies potentially non-diagnostic. • Ferumoxytol can mimic diseases such as haemosiderosis, haemochromatosis and superficial siderosis. • Ferumoxytol interactions with MRI must be recognised by radiologists and non-radiologist physicians.

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
