Comparison of diagnostic precision for bone metastasis of primary breast cancer between BONENAVI version 1 and BONENAVI version 2

Objective The aim of this study was to compare the diagnostic precision of bone scintigraphy with BONENAVI version 1 and BONENAVI version 2 in bone metastasis of primary breast cancer. Methods The subjects were 56 consecutive patients (all women, mean age 59 ± 12.7 years) who underwent bone scintigraphy with 99mTc-MDP and were diagnosed with bone metastasis of primary breast cancer from January 2012 to November 2014. Bone scintigraphy was performed with BONENAVI version 1 and BONENAVI version 2 to calculate artificial neural network (ANN), bone scan index (BSI), and hot-spot values, with ANN ≥ 0.5 considered to reflect bone metastasis for the calculation of sensitivity. Mean ANN, BSI, hot-spot values, and sensitivity were compared between BONENAVI version 1 and BONENAVI version 2, with P
