- Abstract:
- BACKGROUND AND PURPOSE: This study was carried out to determine whether high-resolution 3-dimensional prospective-volume-rendered computed tomographic (CT) angiography can replace conventional intra-arterial digital subtractional angiography in the diagnostic evaluation of patients with an acute subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysm. METHODS: Both techniques were performed in 30 consecutive patients within 2 to 12 hours after their admission to the hospital. RESULTS: In this group of 30 patients, CT angiography with 3-dimensional volume-rendered reconstruction detected 31 aneurysms in 25 patients. Two aneurysms were missed on CT angiography. Conventional angiography detected 33 aneurysms in 27 patients. The authors considered angiograms in 3 patients presenting with SAH as normal. In all cases where an aneurysm was detected on CT angiography, the finding was confirmed by conventional angiography. CONCLUSIONS: CT angiography with 3-dimensional post-processing is a sensitive, noninvasive method that provides a 3-dimensional view of intracranial vessels and the aneurysm. It is also very useful in planning either surgical or endovascular treatment.
