Magnetic Resonance Angiogram (MRA). Guide. A magnetic resonance angiogram (MRA) is a type of magnetic resonance imaging (MRI) scan that uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body.ith MRA, both the blood flow and the condition of the blood vessel walls can be seen. The test is often used to look at the blood vessels that go to the brain, kidneys, and legs. Information from an MRA can be saved and stored on a computer for further study. Photographs of selected views can also be made.

Setting a hot water thermostat at a maximum of 107 F will help to decrease the risk of hot water burns to elderly or disabled people who may have impaired temperature perception. Bathing in water that is too cold could cause a loss of body heat, resulting in hypothermia.
Ideal Temperatures. The ideal temperature for household hot water is 120 degrees Fahrenheit, while the tank itself should be around 130 degrees F.These temperatures are hot enough to kill any bacteria that may be lurking in the system while releasing water cool enough to not scald the skin.ousehold water varies greatly in temperature due to variable settings. Most people do not think too much about the temperature of their water supply, However, certain guidelines should be followed to achieve adequate temperatures.
