Abstract

Objective The aim of the present paper was to comparatively evaluate liver contrast effects and regularity with intermittent second harmonic imaging(ISHI) and conventional consecutive second harmonic imaging (CSHI).Methods Six normal dogs were imaged with CSHI and ISHI after intravenous injection of FX530 (perfluorocarbon ultrasound contrast medium).The subjective scores and video intensities were used to estimate contrast effects.Results ISHI scored significantly higher in subjective evaluation than CSHI.The video intensities obtained from CSHI and ISHI were 129.6±17.36 and 161.24±12.80 respectively( P 0.01).Conclusion There was significant visual liver parenchyma enhancement of ISHI, and it is better than CSHI.
