A selection of heirloom tomatoes. Before the industrialization of agriculture, a much wider variety of plant foods were grown for human consumption.

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).
As the gamma camera images are acquired, the patient's heart beat is used to 'gate' the acquisition. The final result is a series of images of the heart (usually sixteen), one at each stage of the cardiac cycle. Depending on the objectives of the test, the doctor may decide to perform either a resting or a stress MUGA.
