Abstract:
Objective:To explore the application value of acoustic radiation force impulse (ARFI) imaging technology in the dif-ferential diagnosis of benign gallbladder wall thickening or gallbladder carcinoma. Methods:Siemens ultrasound ARFI, involving virtu-al touch tissue imaging (VTI) and virtual touch tissue quantification (VTQ), was used to examine the gallbladder wall in 327 cases. To compare transverse shear wave velocity (VTQ) of gallbladder waland VTI image characteristics. Results:Significant differences exist-ed in the gallbladder wall elastic parameters of normal and benign gallbladder wall thickening, as well as thick-walled gallbladder carci-noma. The ROC curve displayed that a velocity of 2.65 m/s can be used to diagnose gallbladder carcinoma, with sensitivity and specific-ity of 94.0%and 93.7%, respectively. Conclusion:The VTQ parameters were significantly different in benign and malignant gallblad-der wall thickening, thereby exhibiting clinical application value.
