Figure 4. MDCT angiography indicating pulmonary embolism. (A) In the axial reconstruction, an enhancement defect is visible, affecting the right pulmonary artery (arrow). (B) In the coronal reconstruction, some enhancement defects are better highlighted (arrow). (C) In this axial reconstruction, the RCIA (short arrow) and the LCIA (long arrow) are visible, which are compressing the LCIV against the osteophyte (arrow head) and against the body of the fifth lumbar vertebra, respectively. (D) This sagittal reconstruction shows the RCIA (long arrow) compressing the LCIV (short arrow) against an osteophyte (arrow head) of the fifth lumbar vertebra (L5; arrow head). MDCT – multidetector computed tomography; RCIA – right common iliac artery; LCIA – left common iliac artery; LCIV – left common iliac vein.
