abstract = {Background: This study was designed to assess the impact of obesity and acquisition protocol on 123I-metaiodobenzylguanidine (MIBG) indexes of cardiac sympathetic innervation.
Methods: Forty-five patients with heart failure (HF) (38 men, age 58±15 years) underwent 123I-MIBG cardiac imaging. Of these patients, 10 were obese [body mass index (BMI) ≥30 kg/m2]. Ten-minute planar images of the thorax in anterior view were performed 15 minutes (“early” image) and 3 hours and 50 minutes (“late” image) after tracer administration in both supine- and prone-position. Early and late 123I-MIBG heart-to-mediastinum (H/M) ratios and washout rate were computed.
Results: In overall study population, early and late 123I-MIBG H/M ratios and washout rate were comparable between supine- and prone-position acquisitions. Obese patients had a lower early and late 123I-MIBG H/M ratios both in supine (P},
