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.
Sea Level: Water boils at 212 degrees F. and simmers at 190 degrees F. Tepid Water â 85 to 105 degrees F. â The water is comparable to the temperature of the human body. Warm Water â 115 to 120 degrees F. â The water is touchable but not hot. Hot Water â 130 to 135 degrees F. â The water is too hot to touch without injury. Poach â 160 to 180 degrees F. â The water is beginning to move, to shiver. Simmer â 185 to 200 degrees F. â There is movement, and little bubbles appear in the water. Slow Boil â 205 degrees F. â There is more movement and noticeably larger bubbles.
