“…With the increasing availability of multi-detector CT scanners, some have recommended using CT angiography (CTA) to diagnose SAH (124). Of the 116 patients, 6 (5.1%) had aneurysms (with normal CT but positive CSF findings); these patients would have been identified by the standard work-up.…”

“…A strategy of CT/CTA has also been suggested and found to be 100% sensitive in one small study (28). Another study showed that this strategy can exclude SAH with a > 99% post-test probability (29).…”

“…CTA is often used in first-line aneurysm assessment where is has been shown to be of benefit in aneurysm detection [10][11][12][13][14][15][16][17] and presurgical planning [18]. As a technique it has widespread availability and can perform additional tests such as perfusion studies [19], and postoperative assessments [20].…”

The aim of this study was to assess whether the addition of a black blood (BB) sequence to standard three-dimensional time-of-flight (3D-TOF) imaging yields improved quantitative assessment of intracranial aneurysms. Thirty seven patients with 42 proven intracranial aneurysms underwent intra-arterial digital subtraction angiography, 3D-TOF and BB MRI imaging. This multimodality imaging was used to create a composite reference aneurysm description. The 3D-TOF and BB imaging were graded on a subjective seven-point scale to determine what improvement if any the addition of BB imaging yielded. Comparison of measurements from all imaging modalities demonstrated no significant difference (p < 0.01) in aneurysm length/width or parent vessel width. Aneurysm neck measurements were underestimated on 3D-TOF images although there was still a significant correlation (R(2) = 0.72, p < 0.05). Comparison of TOF and BB examinations to the composite reference using the Wilcoxon signed-rank test showed significant improvement in the demonstration of the aneurysm to parent/branch vessels and the morphology/size of the aneurysm neck, particularly in the setting of local haematoma or slow flow (p < 0.001). We propose the addition of the BB sequence as a useful adjunct to 3D-TOF imaging particularly when detailed aneurysm morphology is required or there is thrombus in subarachnoid space.

Computed Tomographic Angiography for the Evaluation of Aneurysmal Subarachnoid Hemorrhage

Abstract: In this pilot study, CTA was found to be useful in the detection of cerebral aneurysms and may be useful in the diagnosis of aneurysmal SAH. A larger multicenter study would be useful to confirm these results.
