Abstract:Objective To explore the application of CT multi-phase enhanced volume scanning fusion and reconstruction
technology in urinary diseases. Methods Image processing and imaging diagnosis of 76 patients with multi-temporal CTU
3D volume scanning were performed by fusion and reconstruction technology. The additional diagnosis value of the fused image
was evaluated by two physicians. Analysis of Kappa test was used to validate the consistency of evaluation results. Results
The quality of images after fusion was able to meet the clinical diagnosis requirements. Of the 76 patients, 13 had no abnormalities
in the urinary system, 5 had urinary tumors, 48 had urinary tract obstruction, and 10 had other abnormalities. Fusion image had more
additional diagnostic value (Kappa=0.749). The multi-phase 3D fusion images stained with pseudo-color could display the
three-dimensional location of the lesion and its relationship with the surrounding tissues in one image. Conclusion Multi-phase
3D image fusion technology can provide high quality image data for the diagnosis and treatment of urinary diseases,
facilitate clinicians to observe and diagnose the lesions in an all-round way, and provide help for clinical treatment.
