A novel PET imaging method shows promise for noninvasively pinpointing sites of inflammation in people with inflammatory bowel disease, which includes ulcerative colitis and Crohn’s disease. The UCLA study is featured in the June issue of The Journal of Nuclear Medicine.
Most arrhythmias are harmless, but some can be serious or even life threatening. During an arrhythmia, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
Ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer.
Many cases of lung disease could be prevented by not smoking, testing for radon, minimizing exposure to particulates such as asbestos, coal, beryllium, silica, molds, grain dust, air pollution, and to chemicals and drugs known to affect the lungs.
There are three common types of nuclear heart scans: the myocardial infarction scan, myocardial perfusion scan, and multigated-acquisition (MUGA) scan (also termed cardiac blood pool imaging). Each of these procedures uses a different radiotracer. The latter two scans are often done while you exercise this is known as stress testing.
Some children are born with heart defects that cause arrhythmias. In other children, arrhythmias can develop later in childhood. Doctors use the same tests to diagnose arrhythmias in children and adults.
Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation (v-fib). Coronary heart disease, heart attack , a weakened heart muscle, and other problems can cause ventricular arrhythmias.
When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed. Occasionally, more images are obtained for clarification or better visualization of certain areas or structures. The need for additional images does not necessarily mean there was a problem with the exam or that something abnormal was found, and should not be a cause of concern for you.
Some of the medicines used to restore a normal heart rhythm are amiodarone, sotalol, flecainide, propafenone, dofetilide, ibutilide, quinidine, procainamide, and disopyramide. These medicines often have side effects. Some side effects can make an arrhythmia worse or even cause a different kind of arrhythmia.
