What total volume is injected during an IVC Gram?

During an IVC gram, which is an imaging study designed to evaluate the inferior vena cava (IVC), the typical volume of contrast material injected is within the range of 30 to 40 ml. This volume is sufficient to create a clear image of the IVC and any potential anomalies or blockages without overloading the patient or causing any adverse reactions associated with higher volumes of contrast.

The choice of 30-40 ml balances the need for adequate visualization while minimizing risks such as contrast-induced nephropathy or discomfort from the volume itself. This moderate volume allows for good quality imaging, essential for accurate diagnosis and subsequent treatment planning. Hence, the selected range effectively aligns with standard operating procedures in interventional radiology, ensuring both safety and diagnostic efficacy.
