IMAIOS is most commonly known for its comprehensive, interactive anatomy atlas – e-Anatomy – available on the web, iPhone, iPad, and Android devices, and an app we have reviewed before. e-Anatomy provides thousands of images in the form of diagrams, plain film, CT and MRI and has become one of the most popular reference tools for radiology among medical students, residents, and clinicians alike. So when iMedicalApps learned that IMAIOS had developed a ninja-themed, anatomy gaming app for iPhone, iPad, and Android devices we had to check it for ourselves. Anatomy Ninja Lower Limb was designed with the intention of helping beginners, like medical students, test their lower limb anatomy through point-and-click identification of anatomical sites on cartoon, plain film, CT, and MRI images.

User Interface

From the home screen you have several options: changing difficulty level, choosing a language, and most importantly volume control. If you decide to give the game a try I highly recommend playing it on mute, as the stereotypical “oriental riff” (with gongs included) can become quite mind-numbing and generally awkward in a public setting.

Once you have selected the difficulty level you are then taken through a course of levels that test your ability to identify the following: general anatomical terms (superior/inferior/plantar/dorsal/etc.), bones, joints, and muscles. Each level will provide you with a set of cartoon, plain film, CT, or MRI images with the corresponding terms that need identifying in a specific time frame in order to move on to the next level. When the allotted time runs out, you are given a detailed description of the structure that could not be identified.

Who would benefit from the app?

  • High school/college students taking anatomy
  • 1st year medical students that are looking for a quick break/distraction from Netter’s Anatomy book or gross anatomy lab
  • Price
    • Free
    • Interactive and well-made graphic design
    • Easy to navigate and use
    • Design and content allows for quick review
    • Can finish the game start-to-finish in a few hours
    • Provides different imaging modalities for testing: cartoon, plain film, CT, MRI
  • Dislikes
    • Only provides structure identification testing – not very practical. Does not provide derivative testing – for example. muscle innervation, range of motion, insertion points, vascular supply.
    • Lots of repetition of structure identification
    • The review has to be done with the progression and order of the game (cannot skip around)
  • Overall

    Given IMAIOS’ reputation, I was excited at first to see what sort of game IMAIOS would develop. However, after playing the game I was quite disappointed with the limited functionality and testing capabilities of the game. All of IMAIOS’ products have catered to users ranging from medical students to radiologists, so it’s accordingly difficult to figure out who IMAIOS made this game for. According to their website, “ Anatomy Ninja is an anatomy game that will help beginners as well as advanced players perfecting their lower limb anatomy knowledge.” It is definitely not an app medical students should pay for, but it’s a free download and could provide some amusement and passive learning.

  • Real World Applicability

    Not a very practical testing tool (at higher levels like medical school) since it only tests pure structural identification. May find more use at the high school or college level.
