What to expect before, during and after an MRI scan
If you’ve never experienced a magnetic resonance imaging (MRI) scan before, you might be anxious about what to expect.
As your heart pumps blood through your body, blood pushes against your arteries’ walls, creating a force known as blood pressure. Blood pressure measurements include both systolic and diastolic pressures. Systolic pressure measures your blood pressure when your heart is beating and pumping blood. Diastolic pressure measures blood pressure while your heart is at rest, between beats. Systolic pressure is measured or read first, followed by the diastolic reading. For example, in a blood pressure reading of 120/80, the systolic pressure is 120 and the diastolic pressure is 80.
Blood pressure is measured as follows:
High blood pressure is a serious condition affecting one in three adults in the United States. If left untreated, it can ultimately lead to other health conditions, including heart failure, stroke and kidney failure.
Blood pressure numbers fluctuate depending on your level of activity. It is normal for your blood pressure to rise when you wake up from sleeping, or when you’re active, excited or nervous. However, if your blood pressure readings are consistently high, more serious health issues can occur. Work with your doctor to establish healthy lifestyle changes and to discuss medications that can help control blood pressure.
Blood pressure often rises as you age. Certain medical conditions can also increase blood pressure, including chronic kidney disease, thyroid disease and sleep apnea. Some medications, such as corticosteroids, asthma medicines and hormone therapy, can contribute to high blood pressure.
Because there are usually no symptoms of high blood pressure, it can go undetected for years. You may experience headaches, although these are uncommon. In order to prevent long-term damage to your blood vessels, heart and other important organs, work with your doctor to lower your blood pressure or prevent high blood pressure.
Knowing your baseline blood pressure numbers can help your doctor to maintain these levels, or lower your blood pressure as needed.
Long-term effects of high blood pressure can cause:

Blood pressure tests are used to diagnose high blood pressure. Often, doctors perform several tests to confirm the results. This easy and painless test is done in a clinic or physician’s office. To measure blood pressure, a blood pressure cuff is placed on your arm and used in combination with a gauge and stethoscope.
High blood pressure is diagnosed when your numbers are 140/90 mmHg or higher. In a person with chronic kidney disease or diabetes, blood pressure over 130/80 mmHg is considered high.
Certain activities and substances can cause your blood pressure to rise. In order to get an accurate reading, follow these guidelines before going in for your test:
Most people with high blood pressure continue treatments throughout their lives. Usually, a combination of medication and lifestyle changes are used to treat high blood pressure. Blood pressure medicines work by removing extra salt and fluid from your body, slowing your heartbeat or widening blood your vessels.
In addition to medication, high blood pressure can be lowered and controlled through lifestyle changes, including:
