Yearly, each EMBRACE II centre is expected to enrol 10-20 patients. The inclusion for the imaging protocol in a given centre is expected to be 70% of patients enrolled in EMBRACE II. We expect that at least 8 institutions will enrol 10 patients per year, which will result in minimum 80 patients per year, and thereby at least 320 patients within the 4-year study period. This number is sufficient to meet the required number of patients for the hypotheses in the overall patient population (sample size 196 patients) and in the high-risk patients (sample size 248 patients )
