Venous excess doppler ultrasound: What radiologists should know in 2026

Figure 6 Serial venous Doppler waveforms demonstrate stepwise improvement, from top to bottom, in a patient with acute kidney injury and hyponatremia, accompanied by parallel improvement in serum sodium and creatinine levels. As shown, recovery of portal venous flow typically precedes normalization of hepatic and intrarenal venous waveforms, while renal venous abnormalities may persist longer due to residual interstitial edema. Na: Serum sodium; AP: Assessment and plan; S wave: Systolic wave; D wave: Diastolic wave. Citation: Koratala A, Ronco C, Kazory A. Multi-Organ Point-Of-Care Ultrasound in Acute Kidney Injury.
