Value of four-dimensional contrast-enhanced ultrasound imaging in the qualitative diagnosis of liver tumors

Abstract

Objective To investigate the value of the four-dimensional contrast-enhanced ultrasound in the qualitative diagnosis of liver tumors. Methods From March 2012 to July 2014, 104 liver patients underwent liver examination. All patients use conventional ultrasound, and then use four-dimensional contrast-enhanced ultrasound to compare the test results in different ways, and analyze the diagnosis, misdiagnosis, detection rate of benign and malignant lesions and the diagnostic value of four dimensional contrast-enhanced ultrasonography in the diagnosis of liver tumors. Results The number of lesions was 85.6±3.9 examined by conventional ultrasound, 16 cases of missed diagnosis, 9 cases of misdiagnosis, the detection rate was 75.9%; the number of lesions was 97.7±4.3 examined by four-dimensional contrast-enhanced ultrasound, 2 cases of missed diagnosis, 1 case of misdiagnosis, the detection rate was 97.1%, the difference was significant(P<0.05). Among the 104 cases, 70 cases were tumor patients or to be determined, 34 cases were non tumor patients. Thirty-two cases of benign liver tumors, 23 cases of malignant liver tumors and 15 cases were determined by routine ultrasound examination; 35 cases of benign liver tumors, 32 cases of malignant liver tumors and 3 cases were determined by four-dimensional contrast-enhanced ultrasound, the difference was significant between the two groups(P<0.05). Conclusions Compared with conventional ultrasound, the four-dimensional ultrasound imaging has a stronger sense of layered and three-dimensional, dynamic and continuous display of hepatic tumor perfusion and its nutrient vessels has obvious advantages, so it is likely to achieve the initial differential diagnosis of benign and malignant tumors. It can be as a new method for the diagnosis of liver tumors. Key words: Contrast-enhanced ultrasound; Four-dimensional; Liver cancer
