| 目的 比较国产Insight NM/CT Pro SPECT/CT仪(永新SPECT/CT仪)与Siemens Symbia T16 SPECT/CT仪(Symbia T16 SPECT/CT仪)图像质量及检出骨转移癌能力。方法 前瞻性对40例确诊或疑诊骨转移癌患者分别采用国产永新SPECT/CT仪及Symbia T16 SPECT/CT仪以相同方法及参数进行全身骨显像及局部融合显像,比较2种设备所获图像质量及其检出病灶能力。结果 40例中,以Symbia T16 SPECT/CT仪所获全身骨显像图像质量为5分者35例、4分5例,检出118处阳性病灶,累及胸部36处、脊柱28处、骨盆30处、四肢20处、颅骨4处;局部断层融合显像图像质量均为5分,检出59处阳性病灶,CT表现为骨质破坏14处、骨密度增高11处、骨密度不均匀34处。利用永新SPECT/CT仪所获全身骨显像图像质量为5分者35例、4分4例、3分1例,检出阳性病灶及其累及骨骼区域均与Symbia T16 SPECT/CT仪一致,所获局部融合显像图像质量、检出阳性病灶累及区域,以及CT表现亦均与Symbia T16 SPECT/CT仪相符。结论 国产永新SPECT/CT仪图像质量及检出骨转移癌能力均与Siemens Symbia T16 SPECT/CT仪相当。 |

| 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 T16 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 T16 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 T16 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. |
