A selection of heirloom tomatoes. Before the industrialization of agriculture, a much wider variety of plant foods were grown for human consumption. During the 19th and early 20th centuries the diversity was huge. Old nursery catalogues were filled with plums, peaches, pears and apples of numerous varieties.
The Multiple Gated Acquisition scan (MUGA) is. a noninvasive tool that creates a moving image of. the beating heart. It is used for assessing the. health of the cardiac ventricles (the heartâs major. pumping chambers).
Second, the LVEF measured by a MUGA scan ejection fraction is highly reproducible. That is, if the LVEF measurement is repeated several times in succession, nearly the same answer is always obtained. (With other tests, variations in the measured LVEF are much greater.)
