“…Remaining concentrated, hypostatic contrast material layers dependently in relation to unopacified whole blood in the intravascular space, creating a characteristic blood-contrast level in the IVC [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] . When visualized on contrast-enhanced CT, this finding is called the “IVC level,” niveau or “dependent pooling sign” [8] , [11] , [12] , [14] . The sign has been observed in shock due to cardiac arrest [8] , [9] , cardiac tamponade [8] , [12] , [14] and myocardial infarction [11] .…”
