Comparing the NET632 SPECT and the Symbia T16 SPECT/CT images in whole-body bone scintigraphy

Objective: To study the equivalence of the Novel Medical NET632 SPECT and the SIEMENS Symbia T16 SPECT/CT in whole-body bone scintigraphy. Methods: A total of 32 cases (21 males and 11 females; aged 60.87 ± 12.25 years) in the Department of Nuclear Medicine of the Affiliated Hospital of Inner Mongolia Medical University from March 2018 to September 2018 were found positive with bone lesions in the whole-body bone scintigraphy using the SIEMENS Symbia T16 SPECT/CT and the Novel Medical NET632 SPECT. Then, the image quality was compared using the same image scoring criteria. The positive lesion involvement area and the number of areas in each patient were determined using the two devices. Results: The image qualities were scored 5, 4, and 3 (including < 3) for 18, 14, and 0 in the Symbia T16 SPECT/CT, and the image qualities were scored 5, 4, and 3 (including < 3) for 16, 16, and 0. A total of 84 positive lesion sites were found in the chest, spine, pelvis, limbs, and skull by using the Symbia T16 SPECT/CT, and the numbers in each location were 19, 24, 20, 16, and 5, respectively. The same number of positive lesions was observed in the same locations for the NET 632 SPECT. Conclusion: The Novel Medical NET632 SPECT and the SIEMENS Symbia T16 SPECT/CT detect the lesions in whole-body bone scintigraphy equivalently. (authors)
