Bipolar disorder causes intense mood swings that cause the person to move from deep depression into mania. Bipolar disorder causes both structural and functional abnormalities in the brain. Neuro-imaging tools such as Magnetic Resonance Imaging...
Gadolinium (Gd) is one of the most abundant of the rare earth elements, first discovered in the late 1800s by the chemists Jean-Charles Galissard de Marignac and Paul-Emile Lecoq de Boisbaudran. Its physical and chemical properties give it...
Attention-Deficit Hyperactivity Disorder, or ADHD, is a neurobehavioral disorder characterized by significant brain structure and function abnormalities. Due to the significant advances in neuro-imaging methods during the last decade, much more is...
Angiography describes a diagnostic procedure that allows doctors to visualize the inside of blood vessels. Angiography can determine the blood flow in and around organs such as the lungs, brain and kidneys, but doctors commonly perform coronary...
Peptides are chains of amino acids joined by what chemists call amide bonds, although biologists typically call them peptide bonds instead. Large peptides are called proteins and are ubiquitous -- all forms of life on Earth have proteins. The term...
MRI, or magnetic resonance imaging, is a medical imaging technique that provides detailed pictures of the structure of your brain. Unlike methods that use radiation, such as X-rays, MRI applies strong magnets. The reasons for abnormal MRI results...
Eye cancer is a rare cancer that can affect the orbit (bony portion surrounding your eye), globe (eyeball) and its adnexal structures (eye tissues such as the eyelid). According to the American Cancer Society, eye cancers can appear at any age but...
So, you want to wail like Joplin or croon like Crosby. The pros make it look easy--just hop on stage and belt one out, right? Well, not exactly. Non-musicians may not realize the physical stamina and dexterity involved in making music. Like...
Coronary arteries supply oxygen-rich blood to the heart. When they have a buildup of cholesterol in the arterial wall, this is considered coronary heart disease (CHD). It is often referred to as atherosclerosis. CHD can cause significant...
Open MRI offers a clear picture of the soft-tissue structures of the human body. These images are not affected by bones and can be taken from any angle or direction. Some of the common open MRI procedures include scans of blood vessels, the brain,...
Cellulite is a term used to describe skin that appears rippled, lumpy and coarse. Its appearance often is compared to orange peel or cottage cheese. Frequently attributed to poor circulation, poor diet and improper exercise, cellulite is actually...
Magnetic resonance imaging, or MRI, is a relatively safe technique for taking three-dimensional images anywhere in the body, according to the Mayo Clinic. The technique uses a magnetic field and radio waves to create highly detailed images that...
Magnetic resonance imaging, or MRI, is a type of imaging that is done for the diagnosis of a variety of conditions. The technology of MRI is based on the creation of magnetic fields, radio waves, and powerful computer software to create accurate...
Magnetic resonance imaging, or MRI, is a noninvasive device used for evaluation, assessment and diagnosis of conditions, diseases and injuries. An MRI generates images of the brain and spine from multiple angles, and it also can provide pictures...
The field of medical imaging has made great strides with advances in technology. Scans are vital in identifying certain disease processes and abnormalities in a quick and noninvasive manner. The first magnetic resonance imaging, or MRI, scan was...
Passive radiators can generate sound at very low frequencies for your home entertainment system. Unlike woofers, which use a more conventional speaker design to generate low-frequency sound, passive radiators do not contain a magnet or a...
Breast cancer arises from rapidly dividing abnormal cells within the breast tissue and can affect both women and men. According to the Susan G. Komen for the Cure organization, 85 percent of non-invasive breast cancer occurs in the mammary ducts...
Your ophthalmologist or examining doctor may test your hearing, reflexes, visual acuity and other skills to determine whether or not you may have a brain tumor. Visual acuity tests can help determine the size and depth of the tumor by indirect...
Your rotator cuff is a group of muscles and tendons that hold your upper arm bone (humerus) in your shoulder socket. Common causes of rotator cuff injuries include falling, lifting and repetitive arm activities, states the Mayo Clinic. Risk...
Magnetic resonance imaging, or MRI, is a method of scanning the body that provides clear, detailed pictures of organs and soft tissue in the human body. A contrast dye is sometimes used to enhance the quality of the scans, although most scanners...
Colon cancer is a silent killer. This disease claims the lives of more than 50,000 individuals per year and is curable if discovered early. Often, the symptoms bring the individual into the clinic too late, when options and survival rates are...
The National Cancer Institute estimates that approximately 22,020 people will be diagnosed with brain cancer in 2010 and that 13,140 of them will die. Brain cancer can be divided into four stages. Stage I is the beginning of the brain cancer, and...
Breast exam methods depend on a doctor's recommendation and also include age, risk factors and prior involvement with breast cancer. Breast exams detect and evaluate changes in the breasts and the detection of breast cancer in its early stages,...
Magnetic Resonance Imaging, or MRI, can be used to look at brain structure, blood flow, metabolic activity and problems in the brain. MRI can help diagnose brain tumors, infections, hormonal disorders, abnormal brain structure and stroke. It may...
Rheumatoid arthritis (RA) is an autoimmune disease caused by the body's own cells attacking the cells that line the joints, known as the synovial cells. Patients suffering from RA experience inflammation of the joints causing stiffness and pain...
Brain atrophy occurs with the loss of neurons or the connections between them. Some degree of atrophy is a normal part of aging, but pathological conditions, such as Alzheimer's or Parkinson's disease, also feature atrophy as a symptom. Common...
Located behind the thigh, the hamstrings are a group of muscles associated with the movement of the hip and knee joints. Athletes participating in sports such as soccer, basketball and tennis or other activities involving sprinting are more prone...
Amyotrophic lateral sclerosis (ALS), commonly called Lou Gehrig's disease, causes progressive degeneration of the nerve cells in the brain and spinal cord. Patients suffering from ALS lose the ability to control muscle movements, including...
Breast cancer is the presence of abnormal transformed cells that can harm healthy tissues. It is diagnosed in more than 192,000 women and almost 2,000 men each year, according to the National Cancer Institute. Screening for breast cancer involves...
