Objective To analyze the effect of SPECT combined with MR in patients with early bone metastasis of malignant tumor, and to point out the improvement direction for the improvement of condition intervention and diagnosis quality of suspected patients with early bone metastasis of malignant tumor. Methods the researchers revisited 105 patients with early bone metastasis of malignant tumors treated and diagnosed in our hospital from January 2017 to December 2018, combined with their subsequent changes of condition and the quality of combined diagnosis and differentiation. The follow-up time was 4-5 years, with an average of 4.45 years. Results SPECT showed that there were 86 patients with early bone metastasis of malignant tumor and 19 patients with early bone metastasis of non malignant tumor. The accuracy, specificity and sensitivity of single diagnosis were 80.95%, 40.00% and 83.00% respectively. The accuracy, specificity and sensitivity of MR diagnosis were 65.00%, 36.00% and 75.00% respectively. There were 97 patients with early bone metastasis of malignant tumor and 8 patients with early bone metastasis of non malignant tumor by SPECT combined with Mr. the accuracy, specificity and sensitivity of combined diagnosis were 95.24%, 80.00% and 96.00% respectively. Conclusion SPECT combined with MR examination can realize the significance of accurate diagnosis of early diseases and provide guidance for follow-up treatment.
