This prospective study was conducted between 03/2016 and 02/2018. One hundred seventy-three patients underwent multiparametric liver MRI at 3 T.

The T1 relaxation time was measured in the liver and the spleen, in the aorta, the portal vein, and the inferior vena cava (IVC). If you dont already have Prism, go to to learn about Prism and download a free demonstration version. T1 relaxation times with and without normalization to the blood pool were compared between patients with ( n = 26) and without ( n = 141) significant liver fibrosis, based on a cutoff value of 3.5 kPa in MRE as the noninvasive reference standard. On the right-hand window, select the datasets which you want to analyze. Those with a tick will be included in the analysis.

For statistics, Student’s t test, receiver operating characteristic (ROC) curve analysis, and Pearson’s correlation were used. NORMALIZATION IN GRAPHPAD PRISM 8 HOW TO However, a reliable prognostic. The T1 relaxation time of the liver was significantly longer in patients with liver fibrosis, both with and without blood pool normalization ( p < 0.001). T1 relaxation time of the liver allowed prediction of significant liver fibrosis (AUC = 0.88), while normalization to the IVC resulted in a slightly lower performance (AUC = 0.82). The lowest performance was achieved when the T1 relaxation times of the liver were normalized to the aorta (AUC = 0.66) and to the portal vein (AUC = 0.62). The T1 relaxation time of the spleen detected significant liver fibrosis with an AUC of 0.68, and 0.51–0.64 with normalization to the blood pool. The T1 relaxation time of the liver is a good predictor of significant liver fibrosis. However, normalization of the blood pool did not improve the predictive value. The T1 relaxation time of the liver is a good predictor of significant liver fibrosis.Normalization to the blood pool did not improve the predictive value of T1 mapping.
