Common auxiliary examinations for intracranial aneurysms

Common auxiliary examinations for intracranial aneurysms include magnetic resonance imaging (MRI), computed tomography (CT), and angiography, which help to accurately assess the location, size, and morphology of the aneurysm.

When diagnosing an intracranial aneurysm, medical imaging is essential to determine the specific features of the lesion. Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to produce detailed images of the brain's internal structures and is particularly suitable for evaluating soft tissues without the risk of radiation. Computed tomography (CT) uses X-rays to obtain cross-sectional images of the head and can quickly detect acute bleeding, making it an important tool in the acute phase of the evaluation. Positron emission tomography (CTAngiography) uses intravenous injection of contrast agents to make blood vessels clearly visible, thereby helping to identify aneurysms and surrounding vascular structures. If a more detailed and precise vascular assessment is required, digital subtraction angiography (DSA) has become the standard, which delivers contrast agents directly to major blood vessels via a catheter, providing high-resolution imaging, although it is an invasive test.

When conducting these examinations, be sure to do so under the guidance of a professional doctor and choose the most appropriate method based on individual circumstances. The combination of routine examinations and personalized assessments is the key to ensuring effective screening and treatment. Before preparing for the examination, patients need to inform their doctors of important information such as possible allergies, body implants, and to fast or quit smoking before surgery to improve image quality. At the same time, regular follow-up and monitoring are also important steps in the management of intracranial aneurysms, especially regular imaging examinations for individuals known to be at risk, which can help detect and address changes early, thereby reducing the risk of rupture. Timely and accurate auxiliary examinations can improve the diagnostic efficiency of aneurysms and provide a basis for further treatment.
