Can CT scan detect brain aneurysms?

Brain aneurysms can be detected through CT examination, especially CT angiography (CTA), which can clearly show the location, size and shape of the aneurysm. CT examination is a non-invasive and rapid imaging method suitable for preliminary screening and diagnosis of brain aneurysms. If a brain aneurysm is suspected, CT examination is one of the preferred imaging methods.

1. Principles and advantages of CT examination

CT uses X-rays and computer technology to generate cross-sectional images that can clearly show the anatomical structure of brain blood vessels. CT angiography can enhance the visualization of blood vessels by injecting contrast agents, helping doctors find aneurysms. CT examinations are fast and have high resolution, making them particularly suitable for emergency situations and for rapid assessment of the condition.

2. Other auxiliary examination methods

In addition to CT, magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) are also commonly used examination methods. MRA does not require injection of contrast agents and is suitable for patients who are allergic to iodine; DSA is the gold standard for diagnosing cerebral aneurysms and can provide more detailed vascular information, but it is an invasive examination and is usually used for diagnosis and preoperative evaluation.

3. Treatment of cerebral aneurysm

The treatment of cerebral aneurysms mainly includes surgical clipping and endovascular interventional therapy. Surgical clipping directly clips the neck of the aneurysm through craniotomy to prevent rupture; endovascular interventional therapy uses a catheter to place a coil or stent into the aneurysm to promote thrombosis and achieve the purpose of sealing the aneurysm. For unruptured aneurysms, doctors will decide whether treatment is needed based on the size and location of the aneurysm and the patient's health status.

4. Prevention and daily management

The key to preventing cerebral aneurysms is to control high blood pressure, quit smoking, and limit alcohol consumption. Regular physical examinations and imaging examinations can help detect aneurysms early. If a cerebral aneurysm is diagnosed, the patient should avoid factors that may induce aneurysm rupture, such as strenuous exercise and emotional fluctuations, and follow the doctor's advice for follow-up and treatment.

Brain aneurysm is a potentially serious disease, and early detection and timely treatment are crucial. CT scans, as a preliminary screening method, can effectively help doctors diagnose brain aneurysms. If a brain aneurysm is suspected, it is recommended to seek medical attention as soon as possible, and determine the treatment plan through imaging examinations and professional evaluations to reduce the risk of rupture and ensure life safety.
