To most people, pearls are considered precious gems, and are among the most popular jewels in the world. It should not be surprising that physicians consider a priceless bit of knowledge about their specialty a "pearl". For the diagnostic radiologist, a pearl may be the formerly elusive insight or fact that paves the way for a correct diagnosis or deeper understanding of a radiologic image. A traditional component of radiology education, pearls are considered on a par with elements such as the teaching file or lecture series. Pearls have also been a mainstay of www.CTISUS.com, where we post approximately 150 to 300 new pearls each month. In this app, we present pearls across 29 of the most popular categories derived from the literature or our imaging experiences. The app also provides a search feature to enhance user interactivity. We look forward to sharing these new insights with you on the latest version where we present literally thousands of pearls.

Verdict
The clearest difference is review sentiment: CTisus iPearls at 100% against Radiology Toolbox Pro's 43%. CTisus iPearls also leads on in-app purchases (none vs 2) and ratings volume (42 vs 7). Radiology Toolbox Pro's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Radiology Toolbox Pro sells 2 in-app purchases, starting at $1.99 per month. CTisus iPearls asks for nothing beyond the download.
Radiology Toolbox Pro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CTisus iPearls has 42 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 43% of Radiology Toolbox Pro's written reviews are positive against 100% of CTisus iPearls's, so the app with the better star average is not the one people write more warmly about.
Radiology Toolbox Pro ships an update every 4 months, CTisus iPearls every 6 months. Both last shipped on November 1, 2026.
