Contrast Study on Pathology and Imageology of Appendical Lesions between Bigh Frequency Ultrasound and Low Frequency Ultrasound

Objective To investigate the features of ultrasound images and evaluate the diagnostic value of ultrasound in appendic lesions. Methods Eighty-seven doubtful appendic lesions were examined and diagnosed with low and high frequency ultrasound respectively. All these cases were verified by pathology after operation. Results The diagnostic accurate rate of high frequency ultrasound in appendic lesions was 94.1% and that of low frequency ultrasound was 42.3%. Conclusions The display rate of high frequency ultrasound is higher than that of low frequency ultrasound in appendic lesions. The high frequency ultrasound can intuitively display appendic lesions which puovide an objective diagnostic basis for colinic.
