The application of multi-slice CT angiography in the diagnosis and treatment of intracranial aneurysm / 国际脑血管病杂志

ABSTRACT

The development of the imaging technology enables diagnostic methods of detect intracranial aneurysms diversified. In recent years, the diagnosis of aneurysms was confirmed by digital subtraction angiography (DSA) which was regarded as the "gold standards". However, CT angiography (CTA), which appears as a fast, non-invasive, and easily achievable examination, is becoming as a new option in clinic. With the development of the CT facility and upgrade of the workstation software, CTA is more widely used in both diagnosing and treating intracranial aneurysm. This article reviews the sensitivity and specificity of CTA in the detection of intracranial aneurysms, and systematically analyzes its advantages and disadvantages as well as its development, imaging methods.
