Independent-Samples T test.

<p>Independent-Samples T test.</p

One-way ANOVA.

<p>One-way ANOVA.</p

Time—density curves (TDCs) from the single input maximum slope.

<p>TDC indicates the enhancement characteristics of the aorta and renal cortex during the first pass. BF can be determined from the maximum gradient of renal cortex.</p

Examples of regions of interest (ROIs) measurements.

<p>(A) ROIs of renal cortex at axial view. (B) ROIs of renal cortex at coronal view. (C) ROIs of whole kidney were defined manually on the axial plane. (D) ROIs of whole kidney on the coronal plane.</p

Example of size measurement and numbers of the entry tears.

<p>(A) Primary entry tear located in the aortic arch. (B) MPR image displaying five small re-entry tears in descending and abdominal aorta, with the primary entry tear locate in the ascending aorta.</p

Bland-Altman analysis on differences between the average blood flow (BF) value of the axial plane and that of the coronal plane.

<p>(A) BF value differences between the two planes for right kidney.(B) BF value differences between the two planes for left kidney. Mean difference (blue line), mean difference ± 1.96 SD (red line).</p

Result of simple regression analysis.

<p>The result indicates the positive correlative relationship between the perfusion values and the size of intimal entries.</p

Residual diagram of model fitting of multi factor regression analysis of BF value.

<p>The result displays all the points of distribution on both sides of central line, the residual plots obey normal distribution.</p

Transverse contrast-enhanced CT scan showed the effect of motion correction.

<p>(A) Motion artifacts were seen as blurring of the kidney and aorta contours (white arrowheads). (B) Most motion artifacts were not seen after correction.</p

Time—density curves (TDCs) of renal cortex from the single input maximum slope.

<p>(A) The ROIs were placed in the abdominal aorta and renal cortex. (B) TDC indicates the enhancement characteristics of the aorta and renal cortex during the first pass. Blood flow (BF) can be determined from the maximum gradient of renal cortical TDC by the peak enhancement of the aorta.</p
