When it comes to heart health, knowing your coronary calcium score can be incredibly valuable. But plaque within your coronary arteries is only one part of the cardiovascular picture.

What about the heart itself?

At Life Guard Imaging Phoenix, AutoChamber Volumetry (ACV) can be added to a CT Coronary Artery Scan to provide additional information about the chambers of your heart and your cardiovascular risk.

First, What Does a Calcium Score Show?

A CT Coronary Artery Scan looks for calcified plaque within the arteries that supply blood to your heart.

Your coronary calcium score reflects the amount of calcified plaque detected and can help provide insight into coronary artery disease and cardiovascular risk.

But a calcium score is focused primarily on your coronary arteries.

Adding ACV allows us to gather another type of information from your heart imaging.

What Does AutoChamber Volumetry Add?

AutoChamber Volumetry analyzes measurements of the heart's chambers from CT imaging.

Why does that matter?

The size and volume of different chambers can provide additional information about cardiovascular health and may be associated with conditions or risks that a calcium score alone isn't designed to assess.

ACV analysis can provide information relevant to:

  • Heart failure
  • Stroke risk
  • Left ventricular hypertrophy
  • Atrial fibrillation
  • 10-year cardiovascular risk assessment

When paired with your coronary calcium score, you're looking at more than plaque alone.

Two Different Views of Your Heart Health

Think of your calcium score and ACV as answering two different sets of questions.

Your calcium score looks at your coronary arteries.
It helps identify and quantify calcified plaque.

ACV looks at your heart chambers.
It provides measurements that can add context about the heart's structure and potential cardiovascular risk.

Neither piece of information should be viewed in isolation or treated as a diagnosis. But together, they can give you and your healthcare provider additional information to consider when evaluating your overall cardiovascular health.

More Information Can Lead to Better Questions

One of the biggest benefits of preventive imaging is discovering information you may not have known to ask about.

You may feel healthy. You may exercise regularly. You may have no obvious cardiovascular symptoms.

That doesn't necessarily tell you what's happening internally.

By combining a coronary calcium score with AutoChamber Volumetry, you can gain a broader look at your cardiovascular health and have more informed conversations with your healthcare provider about what those findings mean for you.

Add More Insight to Your Heart Scan

A calcium score is an important tool for understanding coronary artery health. AutoChamber Volumetry adds another layer of information by evaluating the heart's chambers and associated cardiovascular risk.

At Life Guard Imaging Phoenix, ask about adding AutoChamber Volumetry (ACV) to your CT Coronary Artery Scan.

Because when it comes to your heart, having more information can help you make more informed decisions about your health.

Early Detection. Life Protection.

You go in with a cough. The doctor orders a chest X-ray. It comes back “clear.” You’re relieved—until the symptoms stick around. Sound familiar? X-rays have been a go-to diagnostic tool for decades.

At Life Guard Imaging in Tampa, we offer low-dose CT chest scans designed specifically for preventative care—to give you answers before a problem becomes a diagnosis.
