Online DICOM Viewer for CCTA Heart Scans

Upload and view your existing CCTA scan from your browser. Choose a DICOM file, DICOM folder, or ZIP archive after you sign in.

What Is a DICOM Viewer?

If you received a folder or disc full of files after a heart scan, you may have the original DICOM images. A DICOM viewer opens those files and turns them back into a scan you can move through. The Veevo DICOM Viewer lets you upload a CCTA scan and explore its images from your browser. It does not diagnose your scan, but it makes the images easier to access and discuss with your doctor.

DICOM stands for Digital Imaging and Communications in Medicine. It is the international standard used to store and exchange medical images and related information. A regular photo is usually one image. A DICOM scan can contain many image slices, grouped into different series, along with details that help medical software organize the exam.

How to Open DICOM Files Online

You do not need to install a separate DICOM reader for Windows or Mac. To open your scan with Veevo:

  1. Keep the files together. You can select one DICOM file, a folder containing DICOM files, or a ZIP archive.
  2. Sign in to Veevo so the scan can be connected to your account.
  3. Upload the scan. Veevo checks the files and prepares the images for viewing. A large scan may take a few minutes.
  4. Open the scan from your Scans page, then choose the series you want to view.

Some DICOM files end in .dcm, while others may not have a familiar file extension. You do not need to rename or convert the files before uploading them.

What You Can Do in the Viewer

A DICOM image viewer gives you more control than a screenshot or PDF. In the Veevo viewer, you can:

  • Move through the scan one image slice at a time
  • Switch between the series included with the scan
  • Adjust the window level to change brightness and contrast
  • Pan, zoom, and reset the image
  • Open axial, coronal, sagittal, and 3D views when the selected series supports them

The 3D workspace uses the images already in your scan. It does not create a new medical test or add findings. Not every DICOM series contains the image spacing and other details needed for a reliable 3D view, so some series remain available in 2D only.

What Does a CCTA Scan Show?

Coronary computed tomography angiography, usually shortened to CCTA, uses CT imaging and contrast material to create detailed pictures of the arteries that supply your heart. A qualified physician can use the scan to assess plaque buildup and areas where an artery may be narrowed, according to RadiologyInfo.

A CT scanner creates many cross-sectional images, often called slices. The U.S. Food and Drug Administration compares them to slices in a loaf of bread. A DICOM viewer lets you move through those slices and, when the scan supports it, rebuild them into views from other directions.

Why the Images Do Not Replace Your Report

Your DICOM images and radiology report serve different jobs. The viewer displays the original images. The report records the medical interpretation from a trained physician who reviewed the full exam and your clinical context.

CCTA images are complex. Changing the brightness, looking at a 3D reconstruction, or finding an area that looks unusual is not enough to diagnose plaque or a blockage. Use the viewer to understand where the images came from, keep them accessible, and ask better questions. Use your report and care team for medical conclusions.

How to Protect Your DICOM Files

DICOM files can contain identifying health information. Before using any online DICOM viewer, check how it protects your files, who can access them, and what happens after upload. Avoid placing scan files in public folders or sending them through an unsecured link.

Veevo requires authentication and ties each scan to its owner. Our safeguards include encryption in transit and at rest, access controls, and security monitoring. You can read more in the Veevo Privacy Policy. Keep your original scan files and report as well. An online viewer should not be your only copy.

The Bottom Line

A folder of medical files can feel impossible to use until a DICOM viewer puts the images back together. The Veevo DICOM Viewer gives you a simple way to upload a CCTA scan, move through its image slices, and use supported 3D views from your browser. Keep the radiology report nearby, and ask your doctor to explain any finding you do not understand.
