Screening methods for aneurysm include arterial angiography, enhanced CT, ultrasound, etc., and the choices vary depending on the location of the aneurysm. Aneurysm is a lesion in the wall of arterial blood vessels, resulting in localized bulging of the wall, which can occur in arteries in various parts of the body, and the common ones include cranial cerebral aneurysm, abdominal aortic aneurysm, splenic aneurysm, etc. Screening methods vary according to different parts of the arterial aneurysm. For cranial aneurysm screening, it mainly includes cranial MRA, cranial CTA, and cranial arteriography. Cranial MRA is magnetic resonance cerebral arteriography, which shows the shape and contour of cerebral arterial vessels and can detect localized bulges in the arteries. Cranial CTA is intravenous injection of contrast material and visualization of cranial blood vessels by CT. Cranial arteriography is the injection of contrast material directly into the cranial arteries to visualize the aneurysm. For abdominal aortic aneurysms, confirmation of the diagnosis is usually accomplished by abdominal aortic CTA, which is done by injecting contrast material intravenously to show localized bulging of the artery and its basic outline. For splenic aneurysms, abdominal ultrasound can also be used to detect localized bulging of the artery. Aneurysms occur in many different places, and the examination methods are also different. It is recommended that patients seek medical treatment in time and standardize the examination and treatment under the guidance of professional doctors.
