Answer

Thoracic CT angiography is more sensitive than ventilation-perfusion scanning when pulmonary emboli are suspected in spite of negative findings on venous ultrasonography of the extremities. Arteriography demonstrates small and large aneurysms and focal constrictions between dilated segments in polyarteritis nodosa.
