RESUMEN
Objective To investigate the effects of different concentrations of iopromide injection on liver tissue imaging and adverse reactions. Methods Selected 150 patients of liver without substantial disease patients, were randomly divided into A group (n=50) and B group (n=50) and C group (n=50), after the abdominal plain, Iopromide Injection injection enhanced scan of the abdominal aorta, portal vein, 5 hepatic tissue, strengthen the evaluation value and the adverse reactions were observed, compared with different concentrations of Iopromide Injection imaging effect and adverse reaction of liver tissue. Results A group was injected with 370 mg/mL Iopromide Injection after abdominal aorta was 249.21, the enhancement of portal vein was 132, B group were injected with 350 mg/mL value of 229.32 Iopromide Injection portal vein enhancement, portal vein enhancement value was 121.32, C group were injected with 300 mg/mL Iopromide Injection hepatic enhancement value was 239.21, the enhancement of portal vein was 98.32, the A group and B group, there was significant difference with C group (P<0.05). There was no significant difference in adverse reactions between the three groups when injected with different concentrations of iopromide injection. Conclusion The results show that the imaging effect is better with the increase of concentration, and there is no significant difference between the patients with high concentration contrast agent and low concentration contrast agent.

RESUMEN
Objective To prepare for extraction of liver focal lesion in view of its characteristics of images. Methods A region of interest in the liver region comprising the focal lesion to create a local image was selected firstly, then the threshold to pre-segment the local image was got automatically by using local OTSU in clusters algorithm, at last mark sifting methods to get red of inner holes and outer dissociate areas to get the final contour was used. Results The algorithm can efficiently extract the focal liver lesion. Conclusion The way of extraction of liver focal lesions with local OTSU and zone market screening is rapid and effective.
