Task: Answer Verification
Input (English): Question: Does the biochemical severity of primary hyperparathyroidism correlate with the localization accuracy of sestamibi and surgeon-performed ultrasound?
Answer: Surgeon-performed ultrasound and sestamibi have higher localization rates and PPV, with increasing preoperative serum calcium and PTH levels. Surgeon-performed ultrasound may be a better initial test for patients with lower calcium (<10.5 mg/dL) and PTH (<90 pg/mL) values due to significantly higher localization rates; however, a localizing sestamibi has higher PPV.
Output (English): yes
