Comparative Study of Real-time Gray Scale Ultrasound Contrast and Spiral CT for Diagnosis of Liver Tumor Based on Imaging Technology

Objective: to make a comparative study on the method and application value of imaging technique in the diagnosis of liver tumor under the condition of enhanced CT diagnosis and ultrasound contrast. Methods: in this comparative study, 46 patients with liver tumor were examined, recorded and compared by contrast-enhanced ultrasound and enhanced CT, all images were analyzed retrospectively. Result: no significant difference between ultrasound contrast and CT diagnosis. Conclusion: contrast-enhanced ultrasound is a technique for the diagnosis of liver tumor by contrast agent, no radiation, no poison, there is no significant difference between the two in the diagnosis, the blood supply characteristics of liver tumor can be displayed.
