Online DICOM viewer with AI-powered reports

Most DICOM viewers just show you the images. DICOM Reader shows you what they mean — with an AI-generated, plain-English radiology-style summary and frame-by-frame citations so you can see exactly what the AI found.

What is a DICOM file?

DICOM (Digital Imaging and Communications in Medicine) is the universal standard format for medical imaging. When a hospital or clinic gives you images on a CD, USB drive, or patient portal download, they are almost always DICOM files — typically a folder of files ending in .dcm, or files with no extension at all that open with specialized software.

DICOM files contain not just the image pixels, but also embedded metadata: patient details, imaging parameters, the modality (CT, MRI, X-ray, etc.), acquisition date, and more. DICOM Reader uses all of this context when generating your report.

Supported imaging modalities

DICOM Reader accepts any standard DICOM study. Commonly uploaded modality types include:

CT (Computed Tomography)

Including chest, abdomen, pelvis, brain, and full-body scans

MRI (Magnetic Resonance Imaging)

Brain, spine, joints, abdomen, cardiac, and more

X-ray / Radiography

Chest, bone, dental, and other plain-film studies

Ultrasound

Abdominal, obstetric, cardiac echo, musculoskeletal

Mammography

Standard and digital mammogram studies

Angiography & Fluoroscopy

Vascular imaging and fluoroscopic series

If your study is a standards-compliant DICOM study, DICOM Reader can read it.

What makes DICOM Reader different from other DICOM viewers?

Standard DICOM viewers let you scroll through images. DICOM Reader does that and generates an AI report — so instead of squinting at grayscale images and trying to figure out what you're looking at, you get:

Plain-English findings — what the AI observed, organized by region, in language you can follow
Overall impressions — a concise summary of the most notable observations from the study
Frame-level citations — every finding links back to the exact DICOM frame where it was seen
Follow-up chat — ask any question about your results and get answers grounded in your actual images
No software to install — everything runs in your browser; your account saves reports for later

How to open your DICOM files

Getting DICOM files is easier than most people expect:

From a CD or DVD: Insert the disc, open it in Finder (Mac) or File Explorer (Windows), and look for a folder of image files or a folder named "DICOM" or "IMAGES". Upload that entire folder to DICOM Reader.

From a patient portal: Many hospital portals let you download your imaging studies as a ZIP file. Unzip it, then drag the DICOM folder into DICOM Reader.

From a USB drive: Copy the DICOM folder to your computer or upload it directly from the drive.

Once uploaded, the AI processes every frame automatically. You do not need to configure anything.
