combining these X-rays. It is very useful for showing abnormalities in the structure of the brain such as swelling and enlargement of certain parts. But it does not provide information about brain activity. Another method is Magnetic Resonance Imaging (MRI). It produces a strong magnetic field in which the person’s head is positioned. The radio waves directed at the brain cause the hydrogen atoms to emit signals‚ which are analyzed by a computer. The details of the MRI are superior to CAT scan‚ because

Diagnostic studies: Define/ Purpose of studies Electrocardiogram (EKG) - is a test that checks for problems with the electrical activity of your heart. An EKG translates the heart’s electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves. - Check the heart’s electrical activity. - Find the cause of unexplained

Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. The kidneys are two organs‚ each about the size of a fist‚ located in the upper part of a person’s abdomen‚ toward the back. The kidneys filter wastes and extra fluid from the blood to form urine. They also regulate amounts of certain vital substances in the body. When cysts form in the kidneys‚ they are filled with fluid. PKD cysts can profoundly enlarge the kidneys while replacing

Imaging tests help your doctor visualize your internal organs‚ including your pancreas. Imaging tests used to diagnose pancreatic cancer include ultrasound‚ computerized tomography (CT) scan and magnetic resonance imaging (MRI). Using a scope to inject dye into the pancreatic ducts.

use of imaging to both diagnose and treat disease visualized within the human body. Radiologists use an array of imaging technologies (such as x-ray radiography‚ ultrasound‚ computed tomography (CT)‚ nuclear medicine‚ positron emission tomography (PET) and magnetic resonance imaging (MRI)) to diagnose or treat diseases. Interventional radiology is the performance of‚ usually minimally invasive‚ medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually

In children‚ typical imaging features such as a low lying spinal cord and a thickened filum terminale is confirmed by special imaging techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) scan and ultrasound studies. An MRI uses a magnetic field and radio waves to produce cross-sectional images of particular organs and bodily tissues. In addition‚ demonstration of spina
