Abstract:
Objective: To explore the feasibility of preoperative evaluation of blood supply of bone tumor with enhanced CT. Methods: Totally 455 bone tumors patients who underwent plain and enhanced CT examination 1 month within embolization of corresponding lesion site performed 24 h before surgical operation were retrospectively analyzed. The enhanced CT value, enhancement value (tumor enhanced CT value-tumor plain scan CT value) and the difference between tumor and surrounding muscle after enhancement (tumor enhanced CT value-peripheral muscle enhanced CT value) were obtained. After scoring of angiographic findings, the patients were divided into poor blood supply group (≤1 point) and rich blood supply group (>1 point). The ROC curve was used to analyze CT values to evaluate their efficiency of tumor blood supply. Results: Bone tumors had poor blood supply in 85 patients, while had rich blood supply in 370 patients. The AUC of enhanced CT value, enhancement value and difference with surrounding muscle was 0.967, 0.973 and 0.967, respectively, while of enhanced CT value+enhancement CT value, enhanced CT value+difference with surrounding muscle, enhancement CT value+difference with surrounding muscle was 0.977, 0.969 and 0.979, respectively, of combination of all three CT values was 0.979. Conclusion: It is feasible to evaluate blood supply of bone tumor with enhanced CT before operation, and tumor enhancement CT value is the most effective.
