“…These studies reported variable sensitivity and specificity values ranging from 67% to 100% and 86% to 100%, respectively 8 18–21. One study19 compared CTA with DSA in detecting aneurysms in SAH patients and reported a sensitivity of 91% and specificity of 95% after 1 year's experience of using CTA. In this report, 13 out of 144 aneurysms were missed by CTA.…”

“…Both of these cases occurred early in the study (the case with the 4 mm aneurysm located at RMCA was our first patient) when our experience was sub par. Lack of experience has been reported as a cause of misdiagnosis by other studies as well (2,8,18,24,32). Pedersen et al (32) reported an increase in the sensitivity of CTA from 88% to 94% after 1 year's experience.…”

Pedersen et al (32) reported an increase in the sensitivity of CTA from 88% to 94% after 1 year's experience. Westerlaan et al (1) recommends that if a cranial CTA study is reported as normal despite a strong clinical suspicion of a ruptured aneurysm, a second radiologist should review the study before scheduling a repeat angiography.…”

“…The learning curve of experience has been described for CT angiography. 33 There is no trend toward higher diagnostic performance in smaller studies, so the funnel plot gives no indication for publication bias. 34 The implications of the results of this meta-analysis for the position of MRA in clinical practice need to be discussed.…”

Background and Purpose-The aim of this study was to evaluate the sensitivity and specificity of MR angiography (MRA) in the diagnosis of ruptured and unruptured intracranial aneurysms. Methods-A systematic search was performed on 4 electronic databases on relevant articles that were published from January 1998 to October 2013. Inclusion criteria were met by 12 studies that compared MRA with digital subtraction angiography as reference standard. Two independent reviewers evaluated the methodological quality of the studies. Data from eligible studies were extracted and used to construct 2×2 contingency tables on a per-aneurysm level. Pooled estimates of sensitivity and specificity were calculated for all studies and subgroups of studies. Heterogeneity was tested, and risk for publication bias was assessed. Results-Included studies were of high methodological quality. Studies with larger sample size tended to have higher diagnostic performance. Most studies used time-of-flight MRA technique. Among the 960 patients assessed, 772 aneurysms were present. Heterogeneity with reference to sensitivity and specificity was moderate to high. Pooled sensitivity of MRA was 95% (95% confidence interval, 89%-98%), and pooled specificity was 89% (95% confidence interval, 80%-95%). False-negative and false-positive aneurysms detected on MRA were mainly located at the skull base and middle cerebral artery. Freehand 3-dimensional reconstructions performed by the radiologist significantly increased diagnostic performance. Studies performed on 3 Tesla showed a trend toward higher performance (P=0.054).

CTA in patients with acute subarachnoid haemorrhage: A comparative study with selective, digital angiography and blinded, independent review

Abstract: CTA in SAH is of great value in demonstrating vascular anatomy and the exact size of an aneurysm. However, IA-DSA is still needed for diagnostic evaluation in aneurysms smaller than 5 mm in diameter, especially in those located near bony structures.
