We estimated the correlation between MRI\u2010 and TVS\u2010derived CL measurements using Spearman's rank correlation coefficient, with stratified analysis by pertinent clinical variables. Bland\u2013Altman analysis was used to evaluate the agreement between the two imaging methods. Finally, for the subset of patients examined in the second trimester, we calculated the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of CL \u2264 25 mm on fetal MRI for predicting a short cervix with CL &lt; 25 mm on TVS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We screened 132 patients, of whom 31 were excluded owing to incomplete data and one was excluded due to having a cervical cerclage in place.
