About RadRef for iOS

RadRef is the offline, iOS version of the portal which inventories normal values and ranges assessed by various medical imaging modalities including radiography, CT scanning, MRI, ultrasonography and even more. Use this exhaustive and up-to-date list for a quick refresher in the reading room or as a reference for less-frequently used measurements.

More than 1000 unique values

With more than 1000 unique values, ranges and formulas, RadRef is the most comprehensive reference on iOS for diagnostic imaging measurements. With both frequently and less-frequently-used items included, chances are the value your are looking for will be there.

Covers all subspecialties

Relevant measurements can be accessed for every subspecialty, including:

  • Abdomen
  • Cardiothoracic
  • Genitourinary
  • Gynecology & Obstetrics
  • Head & Neck
  • Musculoskeletal
  • Neuroradiology
  • Pediatrics
  • Vascular

Tens of formulas

For some measurements, the normal expected value must be calculated. Access the standard formulas right within the app. Most useful for pediatrics and obstetrics cases.

Complete pediatric tables

Access comprehensive age-based tables of normal pediatrics measurements. All the important data is displayed in a single easy-to-read screen. Ideal as a quick reference when the normal range cannot be determined through a formula.

Direct link to original reference

Because accuracy and reliability is just as important comprehensiveness, all provided values include direct link to the original reference, be it a textbook, a scientific article or, when possible, the original study.

Sorted by anatomic location

Easily find the required value by browsing through anatomic locations within each subspecialty. Normal values are all displayed on the menu screen for quick access. Clicking on a value leads to a detailed screen where more information can be found, including applicable imaging modalities and original reference, as well as the formula, measurement procedure or complete tables depending on the case.

Offline access

RadRef for iOS is a local copy of every single entry of the database, giving you access to any value you need even in the most remote part of the hospital where Wi-Fi might not be available. And by weighting less than 6MB, offline access does not come at the price of filling up your iOs device!

Continuously updated

Enjoy free continuous updates as the RadRef database is improved and features are added.

RadRef requires iOS 6.0 or later running on an iPhone, iPod Touch or iPad.
