Abstract

Positron emission tomography (PET) and the maximum standardized uptake value (SUVmax) is a useful technique for assessing malignant tumors. Measurements of SUVmax in multiple lesions per patient frequently require many time-consuming procedures. To address this issue, we designed a novel interface named SUV Navigator (SUVnavi), and the purpose of this study was to investigate its utility. We measured SUVmax in 661 lesions from 100 patients with malignant tumors. Diagnoses and SUVmax measurements were made with SUVnavi, 2D, and 3D measurements. SUV measurement accuracy in each method were also evaluated. The average reduction in time with SUVnavi versus 2D was 53.8% and 3D was 37.5%; time required with SUVnavi was significantly shorter than with 2D and 3D (P < 0.001 and P < 0.001, respectively). The time reduction and lesion number had a positive correlation (P < 0.001 and P < 0.001, respectively). SUVmax agreed with precise SUVmax in all lesions measured with SUVnavi and 3D but in only 466 of 661 lesions (70.5%) measured with 2D. SUVnavi may be useful for rapid [18F]-fluorodeoxyglucose positron emission tomography/computed tomography ([18F]-FDG PET/CT) image interpretation without reducing the accuracy of SUVmax measurement.
