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.
Very hot water temperature can cause burns with great rapidity, and as such, care in setting your hot water heater is required. Setting the hot water temperature lower also means a savings in energy bills for heating the home's water in many cases.However, a lower temperature does mean you will run out of hot water more quickly. Most experts recommend that hot water temperature should not exceed 125Â° F (51.66Â° C).ome pediatricians instead suggest setting the hot water temperature at 120Â° F (48.88Â° C). With this water temperature, a child would have to run water over the same place for ten minutes prior to receiving a severe burn.
