Figure 3 Graphical presentation of the ultrasound examinations and analyses of renal cortical perfusion in the 2 patients with different free thyroxine concentrations. Graphics present the perfusion relief (white arrow) and the perfusion intensity (white curve) assessment in the renal cortex. A diagram Pixels/Intensity is a quantitative evaluation of RCP showing how many pixels within the investigated region of interest are related to the intensity of the respective value. A box-plot diagram (#) expresses the distribution of pixel perfusion intensity, in percentiles (whisker: 2.5% and 97.5%; box 25% and 75%; vertical line in the box 50% – median). A – examination of a patient with FT4 25.93 pmol/L and RCP 1.427 cm/s; B – examination of a patient with FT4 14.77 pmol/L and RCP 0.159 cm/s; * – renal cortex; m – renal medulla.
