Brain tumor MRI Brain tumor imaging Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns water molecules in your body. Radio waves cause these aligned atoms to produce faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of bread. Why it's done MRI is a noninvasive way for your doctor to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of problems. MRI of the brain and spinal cord MRI is the most frequently used imaging test of the brain and spinal cord. It's often performed to help diagnose: • Aneurysms of cerebral vessels • Disorders of the eye and inner ear • Multiple sclerosis • Spinal cord disorders • Stroke • Tumors • Brain injury from trauma A special type of MRI is the functional MRI of the brain ( fMRI). It produces images of blood flow to certain areas of the brain. It can be used to examine the brain's anatomy and determine which parts of the brain are handling critical functions. This helps identify important language and movement control areas in the brains of people being considered for brain surgery. Functional MRI can also be used to assess damage from a head injury or f...

Normal chest x ray Radiological anatomy is where your X-ray), computed tomography ( CT) and magnetic resonance imaging ( MRI). X-ray and CT require the use of ionizing radiation while MRI uses a magnetic field to detect body protons. MRI is the safest among the three, although each technique has its benefits. The preferred method depends on the structures we wish to examine.  Scan interpretation will be a lot easier for you if you have analyzed Key facts X-ray radiography An imaging technique which uses beams of electromagnetic waves (x-rays) to produce radiographs that depict the tissues in two dimensions based on their density. Commonly used for assessment of chest, abdominal and skeletal anatomy. Computed tomography (CT) An imaging technique which uses X-ray beams to produce images that depict the tissues in two and three dimensions based on their density. Commonly used for assessment of musculoskeletal system, parenchyma of solid organs, distribution of body fluids. Magnetic resonance imaging (MRI) An imaging technique which uses radio-waves and magnetic fields to produce images based on the tissue’s proton (hydrogen) levels. Commonly used for examination of soft and nervous tissues. Ultrasonography (U/S) An imaging method which uses high frequency sound waves to depict tissues based on their density. Wide array of indications (e.g. Doppler U/S, breast U/S, obstetric U/S) Nuclear medicine Spectrum of imaging methods used for examining the function of specific body p...

There's always questions about radiation exposure from medical imaging. Patients want to know if radiation from Over 80 million CT scans are performed in the United States each year, compared with just three million in 1980. There are good reasons for this trend. CT scanning and nuclear imaging have revolutionized diagnosis and treatment, almost eliminating the need for once-common exploratory surgeries and many other invasive and potentially risky procedures. The benefits of these tests, when they're appropriate, far outweigh any radiation-associated cancer risks, and the risk from a single CT scan or nuclear imaging test is quite small. But are we courting future public health problems? Exposure to ionizing radiation on the rise The radiation you get from x-ray, CT, and nuclear imaging is ionizing radiation — high-energy wavelengths or particles that penetrate tissue to reveal the body's internal organs and structures. Ionizing radiation can damage DNA, and although your cells repair most of the damage, they sometimes do the job imperfectly, leaving small areas of "misrepair." The result is DNA mutations that may contribute to cancer years down the road. We're exposed to small doses of ionizing radiation from natural sources all the time — in particular, cosmic radiation, mainly from the sun, and radon, a radioactive gas that comes from the natural breakdown of uranium in soil, rock, water, and building materials. How much of this so-called background radiation you are e...

What Are X-Rays? X-rays are images that use a small doses of ionized radiation to take pictures of the inside of your body called radiographs. Why Are X-Rays Done? X-rays can help doctors diagnose things like: • Broken bones • Dislocated joints • Arthritis • Causes of a bdominal pain, in some instances • Cancer • Tooth decay Doctors can also use X-rays to find an object that a child or adult swallowed. An X-ray can be used to check your Other ways doctors use specific X-ray procedures include: • Mammography: This is an exam that puts your breast between a support plate and a second plate called a paddle, then a series of X-rays are taken. Doctors look closely at the images for signs of cancer or other issues. • Computed tomography (CT) scan: A computer puts together a series of X-rays, taken from different angles, to make a 3D image and give your doctor a more detailed picture. • Fluoroscopy: Sometimes called an ”X-ray movie,” this procedure shoots a continuous X-ray through a part of your body so doctors can see that part and how it moves. It’s most commonly done to look at bones, muscles, joints, and organs like your heart, kidneys, and lungs. What Happens During an X-Ray? Most X-rays don’t require any special preparation. The doctor may ask you to take off jewelry, Doctors can take images while you stand up or lie down. It depends on the area of your body being examined. The X-ray tube hangs over the table. The film is in a drawer under the table. The machine sends a be...
