It is a painless, non-invasive, and bloodless diagnostic method that allows the assessment of blood flow without the use of catheters, as required in conventional angiography.<\/p>\n\n\n\n<p>This technique enables the imaging of arteries and veins in virtually any part of the body, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the vessels of the brain<\/li>\n\n\n\n<li>the carotid arteries and neck vessels<\/li>\n\n\n\n<li>the vessels of the upper and lower limbs<\/li>\n\n\n\n<li>the thoracic and abdominal aorta<\/li>\n\n\n\n<li>the renal and iliac arteries<\/li>\n<\/ul>\n\n\n\n<p>Magnetic resonance angiography is widely used for the diagnosis and monitoring of vascular diseases such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>stenosis (narrowing of vessels due to atherosclerosis)<\/li>\n\n\n\n<li>occlusions<\/li>\n\n\n\n<li>aneurysms<\/li>\n\n\n\n<li>vascular malformations<\/li>\n\n\n\n<li>thrombosis<\/li>\n<\/ul>\n\n\n\n<p>Thanks to its high diagnostic accuracy, it plays a crucial role in the early detection of conditions that may lead to serious events, such as stroke.<\/p>\n\n\n\n<p>In many cases, an intravenous contrast agent (usually gadolinium-based) is administered to enhance the visualization of the vessels. This contrast agent is generally considered safe; however, a detailed medical history is taken beforehand to identify any allergies or kidney function issues.<\/p>\n\n\n\n<p>One of the main advantages of this method is the absence of ionizing radiation, making it suitable even for younger individuals or for repeated follow-up examinations when necessary.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Duration and Procedure<\/h3>\n\n\n\n<p>The examination typically lasts between 20 and 45 minutes, depending on the area being studied. The patient lies on a special table that moves into the MRI scanner. During the scan, it is important to remain still to ensure high-quality images. In some cases, the patient may be asked to hold their breath for a few seconds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Preparation<\/h3>\n\n\n\n<p>For magnetic resonance angiography, the following are recommended:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>fasting for 4\u20136 hours prior to the examination<\/li>\n\n\n\n<li>avoidance of heavy meals the day before<\/li>\n\n\n\n<li>a special diet 1\u20132 days prior, if instructed by the physician<\/li>\n\n\n\n<li>informing the physician about any medications, allergies, or chronic conditions<\/li>\n<\/ul>\n\n\n\n<p>Magnetic resonance angiography is a safe and reliable diagnostic tool that combines high image quality with patient comfort, contributing significantly to the prevention and early diagnosis of vascular diseases.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"featured_media":8971,"parent":0,"template":"","meta":{"_acf_changed":false,"_uag_custom_page_level_css":"","_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"normal-width-container","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center
