Use of Contrast-Enhanced Ultrasound to Study Relationship between Serum Uric Acid and Renal Microvascular Perfusion in Diabetic Kidney Disease

Figure 1

The parameters derived from the CEUS perfusion model. These include maximum intensity (IMAX, with respect to IMAX of the reference ROI), rise time (RT, independent of the time origin), time to peak (TTP), and mean transit time (mTT, corresponding to the center of gravity of the perfusion model). AUC (area under curve) is divided into two parts including AUC1 (area under ascending curve) and AUC2 (area under descending curve).
