What did MRI do?
Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord.
What is the difference between an MRI and an angiogram?
Overview. Both an MRI and MRA are noninvasive and painless diagnostic tools used to view tissues, bones, or organs inside the body. An MRI (magnetic resonance imaging) creates detailed images of organs and tissues. An MRA (magnetic resonance angiography) focuses more on the blood vessels than the tissue surrounding it.
How do Mras work?
MRA uses a magnetic field, radio waves and a computer to create images of soft tissues, bones, and internal body structures. An MRA of the brain is used to produce two three-dimensional images of the blood vessels. MRA is primarily used to detect narrowing of the arteries and to rule out aneurysms.
What can an MRI of the leg detect?
Unlike an X-ray, which takes pictures of your bones, a knee MRI lets your doctor see your bones, cartilage, tendons, ligaments, muscles, and even some blood vessels. The test can show a range of problems, including: Damaged cartilage. Torn tendons or ligaments.
What are MRAs in heart failure?
Aldosterone receptor antagonists, also called MRAs, block the effects of a hormone produced naturally by your adrenal glands which can cause your heart failure to get worse. Aldosterone receptor antagonists affect the balance of water and salts going into your urine and are weak diuretics.
Is MRAs a diuretic?
MRAs, such as spironolactone and eplerenone, are relatively weak diuretics at commonly used doses, but are generally used in HF patients as neurohormonal antagonists rather than for their diuretic properties (as described in detail later).
