Heart CT Scan
许多人直到为时已晚才意识到自己有心脏病，因为第一个症状通常是心脏病发作。幸运的是，心脏CT扫描可以提供早期预警。
A heart CT scan is a non-invasive study of coronary arteries, which supply blood to the heart. The scan checks for early stages of heart disease by measuring calcified plaque buildup (made of calcium, fat, cholesterol and other substances) along the artery walls.
This buildup narrows the arteries and affects the flow of blood to the heart. If blood flow becomes completely blocked, a heart attack can occur.
The results of a heart CT scan are given as acalcium score.This information can help predict your risk of having a heart attack before symptoms even appear.
它适合我吗?
A heart CT scan isn’t for everyone, so talk to your doctor about whether it makes sense for you. It's most useful when considered along with other risk factors for a heart attack, such as family history of heart disease, high blood pressure and unhealthy cholesterol.
Preparing for the Scan
There are no special prep instructions for this test.
What to Expect
The scan only takes about 10 minutes and is done using computed tomography (CT), which uses X-rays and computers to create detailed images of the heart.
During the scan:
- You lie on a platform that slides through a tube that looks similar to a doughnut.
- You will need to stay very still.
- You may be asked to hold your breath for short periods.
- 你可能会有小而粘的圆盘，附着在你胸部的电线(电极)上，记录你的心跳。
Once the test is done and your appointment is finished, you can go back to your normal routine.
Cost
Because it’s a screening examination, a heart CT scan is not covered by most insurance companies or Medicare. Payment is due at the time of service.
The exam cost is $99, and you can pay with cash, check or credit card. (We will not bill your insurance.) The price includes both the scan and review of the results.
Test Results
A cardiologist will interpret your exam results, and a written report will be mailed to your home.
