Cardiac Magnetic Resonance Imaging in Polyarteritis Nodosa
Bibliographic record
Abstract
Although cases of coronary artery aneurysm formation and myocardial infarction due to dissection in patients with polyarteritis nodosa (PAN) have been reported 1,2 , there are no reports evaluating widespread coronary arteritis accompanied by myocardial damage using cardiac magnetic resonance imaging (cMRI).We performed cMRI on a young man with widespread coronary arteritis resulting from PAN, and evaluated the changes in myocardial involvement after 3 months.This case involved a 35-year-old male who, in July 2009, noted unintentional weight loss (4 kg in 1 month), fever, and joint pain.Toward the end of August, he presented for examination after noticing paresthesia and myalgia in both lower extremities and discomfort in the chest unrelated to physical exertion.There was nothing remarkable in medical histories of the patient or family.There were no irregular vital signs but there was muscular tenderness in both lower extremities.Electrocardiogram revealed slightly elevated ST in II, III, and aVF leads.Laboratory examination showed leukocytosis (11,000/µl), elevated C-reactive protein (11.42 mg/dl), and elevated creatine kinase (CPK 170 U/l, CPK-MB 35.9), but no evidence of renal or hepatic dysfunction.No obvious

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
