Republican presidential candidate Carly Fiorina says that âso littleâ of the charitable donations to the Clinton Foundation âactually go to charitable worksâ â a figure CARLY for America later put at about 6 percent of its annual revenues â but Fiorina is simply wrong.
An ultrasound test (sonogram) is a painless exam that uses sound waves to check a pregnancy or to get images of body organs. An ultrasound can give your doctor almost the same information as an x-ray, but it doesnât expose you to harmful radiation.
An echocardiogram uses an ultrasound machine to take a scan of your heart. It is carried out by a specially qualified technician and is sometimes just called an âechoâ, âecho heartâ or âechogramâ. Ultrasound machines detect sounds with such high frequencies that they cannot be heard by humans. The test is called an echocardiogram because the sound âbouncesâ or echoes back from the heart tissue to give an accurate picture of the heart. For example, ultrasound passes easily through fluid so there is little echo from the blood in the heart, which would otherwise affect the result.
