Abstract:
Objective To compare imaging quality and detection capability of bone metastases between Insight NM/CT Pro SPECT/CT(Insight SPECT/CT)and Siemens Symbia T16 SPECT/CT(Symbia T16 SPECT/CT)scanners.Methods Totally 40 patients with diagnosed or suspected bone metastases were prospectively enrolled.Whole-body bone imaging and local tomographic fusion imaging were performed using Symbia T16 and Insight SPECT/CT scanners with same method and parameters,and imaging quality and detection capability were compared between 2 devices.Results Among whole-body bone imaging acquired with Symbia T 16 SPECT/CT,the imaging quality score was 5 in 35 cases and 4 in 5 cases,and detected 118 positive bone lesions,including 36 lesions involved chest,28 involved spinal cord,30 involved pelvic bones,20 involved limbs and 4 involved cranial bones.The imaging quality score of local tomographic fusion imaging obtained with Symbia T16 SPECT/CT was 5 in all 40 cases,and 59 positive lesions involved bone regions were detected,including 14 lesions presented as bone destruction,11 presented as increased bone density and 34 showed uneven bone density on CT.Meanwhile,the whole-body bone imaging quality score acquired with Insight SPECT/CT was 5 in 35 cases,4 in 4 cases and 3 in 1 case,and both the detected positive lesions and the involved bone regions were consistent with those of Symbia T 16 SPECT/CT.Furthermore,the imaging quality,detected positive lesions and their involved regions,as well as CT manifestations on local tomographic fusion imaging obtained with Insight SPECT/CT scanner were all consistent with those of Symbia T 16 scanner.Conclusion The imaging quality of whole-body bone imaging and local tomographic fusion imaging of bone metastases of domestic Insight SPECT/CT were comparable to those of Siemens Symbia T16 SPECT/CT.
