denotes |
OBJECTIVES: CEUS can provide accurate quantitative estimates of intestinal wall microvascularization in Crohn's disease. |
| T3 |
272-513 |
Sentence |
denotes |
We hypothesized that inflammation of the intestinal wall is correlated not with the amount of wall vascularization (study of vascularization patterns, SVP) but with the degree of wall flow during a period of time (time-intensity study, TIS). |

514-778 |
Sentence |
denotes |
Our objective was to discover whether CEUS SPV and/or CEUS-TIS reflect(s) vascular inflammation of the intestinal wall and display(s) correlation with clinical activity of the disease at the time of the examination (T0) or at the 3- and 6-month follow-up (T3, T6). |
