# MRI Viewer vs CT Anatomy

The clearest difference is rating: CT Anatomy at 4.6 against MRI Viewer's 3.4. CT Anatomy also leads on ratings volume (125 vs 7). MRI Viewer's advantage is in-app purchases (none vs 1) and review sentiment (33% vs 0%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. CT Anatomy sells 1 in-app purchase, starting at $9.99 per year. MRI Viewer asks for nothing beyond the download.

CT Anatomy holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: CT Anatomy has 125 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 33% of MRI Viewer's written reviews are positive against 0% of CT Anatomy's, so the app with the better star average is not the one people write more warmly about.

MRI Viewer ships an update every 21 months, CT Anatomy every 22 months. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
