Value of early diagnosis of sepsis complicated with acute kidney injury by renal contrast-enhanced ultrasound

Figure 1 Grouping diagram of sepsis patients based on acute kidney injury diagnostic criteria. AKI: Acute kidney injury.

Figure 2 Contrast-enhanced ultrasound in patients with septic acute kidney injury and non-acute kidney injury sepsis. A: Contrast-enhanced ultrasound (CEUS) time-intensity curve (TIC) for patients with non-acute kidney injury (AKI) sepsis; B: CEUS TIC for patients with septic AKI.

Figure 3 Receiver operating characteristic analysis of each potential indicator for the diagnosis of septic acute kidney injury. A: Clinical indicators (Systemic inflammatory response score, blood lactic acid, serum creatinine, blood urea nitrogen) for the diagnosis of septic acute kidney injury (AKI); B: Contrast-enhanced ultrasound indicators (Peak intensity, wash in slope, rise time) for the diagnosis of sepsis AKI. SIRS: Systemic inflammatory response score; Lac: Blood lactic acid; Scr: Serum creatinine; BUN: Blood urea nitrogen; WIS: Wash in slope; PI: Peak intensity; RT: Rise time.
