36790-4MRA Inferior vena cava + tributariesActive

Term Description

This study is used to image the inferior vena cava (IVC) and its tributaries. The IVC is formed from the two common iliac veins at the L5 vertebral level. Other tributaries draining into the IVC include the lumbar veins, right gonadal vein, renal veins, right suprarenal vein, hepatic veins and inferior phrenic veins. The left gonadal and suprarenal veins drain into the left renal vein and are not directly connected to the IVC.

Change Reason
The scale has been changed from "Nar" to "Doc" to fit with the CDA model.; Method of "MRI.angio" was changed to "MR.angio". The LOINC/RadLex Committee agreed to use a subset of the two-letter DICOM modality codes as the primary modality identifier. "MR.angio" is an allowed modality + modifier code.; Changed System from "Vena cava.inferior+Lower extremity veins" to "Abdomen>Vena cava.inferior & Pelvis+Lower extremity.bilateral>Tributaries" to conform with LOINC/RadLex unified model
