Fig. 7

A. 45-year-old male without hematuria. CECT shows normal LRV without compression at AM portion and homogeneously opacified LRV and IVC. B, C. 17-year-old male with NCS. B. Doppler US of LRV at AM portion shows high PV (226 cm/s) of LRV. C. CECT in early cortical phase shows jetting of contrast-opacified venous flow (arrow) into IVC across AM portion of LRV. D. 28-year-old female with NCS. CECT shows severely compressed LRV at AM portion, with beak sign (arrows). Note jetting (open arrow) of contrast-opacified venous flow into IVC across AM portion of LRV.
