Abstract

The aim of this study was to detect of liver metastasis by contrast enhanced Doppler ultrasound with
measuring the contrast transitions times. Material and methods: We estimate 60 patients with colorectal
carcinoma with or without liver metastasis and 60 healthy subjects. Results: The mean value of HATVTT
in control group was 32 ± 1,8sec. The HATVTT results in group with or without liver metastasis were:
25 ± 2,1; 24 ± 1,9; 23 ± 2,0; 21 ± 2,4 and 19 ± 1,8sec versa 32 ± 1,6; 32 ± 1,0; 31 ± 1,4; 29 ± 1,9; and
26 ± 1,5sec respectively. The percents of liver metastasis were: 6,6%, 15%, 20,0%, 28,3% and 36,6%
inside in subgroups. There were no cases with normal HATVTT and liver metastasis. Conclusion: We
can constitute that the contrast transition time has a significant impact on the detection of metastases,
in particular the very small dimensions, which meaning is significantly longer than classical B-mode
ultrasonography.
Keywords: Liver metastases, Doppler, Contrast Enhanced Ultrasonography, Pulse Harmonic Imaging,
