Second, IMAIOS has included different windows for the CT scans and different pulse sequences for the MRIs, which is truly amazing! These different ‘settings’ are very crucial for clinicians and radiologists to make their observations and diagnoses, and being familiar with how each structure or disease state looks under these ‘settings’ is in fact important.

Virtually everything on every image is pinned and labeled in the CT and MR modules, and fortunately you can toggle the pins on or off based on the category of structures, such as vessels, nerves, or bones. However, if you choose to have everything labeled on the screen the amount of data shown can be quite overwhelming. Search functions are also available as well exclusively for each specific module.

As for the diagrams, angiograms, 3D-reconstructions, and other imaging modalities included in the app, their presentations and navigations are pretty straight forward and really require no introduction. The mere inclusion of these modules already blows my mind.

I tend to emphasize on the goals and objectives of apps in my reviews, because I believe it is important for the practicality and the success of an app. After all, smart phones are irreplaceable nowadays because of their unique functionality and convenience, and that should hold true for their apps as well. Apps should generally serve as tools for their users and have specific purposes, like screwdrivers for screws or maps for directions. Users should be able to identify the exact situations where they would benefit from firing up a specific app. If the app strays away from the initial goals or loses its focus, then ultimately its users will become just as confused as the app itself on when to use it.

That being said, e-Anatomy is great in that there is no one instance when it strays away from its goals. This app does no more than identify anatomy structures, and no descriptions and no links are provided whatsoever. E-Anatomy is purely a human atlas and no more, but, it  does do this very well.

There are a couple of downsides that I have noticed with e-Anatomy. First, scrolling may be a little difficult at times. You can zoom in on images, but once zoomed in, you can’t scroll. You would need to zoom out to resume scrolling. Other than that, because scrolling is done with a single finger swipe, the app must take the time to differentiate whether you are trying scroll or tap on pins, and, thus, there is a noticeable lag in response. Sometimes the app will try to overcompensate for this lag and really jump too far than one would intend to scroll.

Moreover, as I mentioned before, sometimes the information, either the number of modules or the abundance of pins on an image, may be overwhelming. There is no guide on differentiating between important structures versus the less important ones. For those who are learning basic anatomy, knowing which structures are more important than others may prove to be a bit difficult with this app alone.

Finally, because of the high-resolution images and the amount of clutter the pins may cause, even my 4.8 inch screen on my Samsung Galaxy SIII seems too small at times (I can’t wait until I get a tablet).

Review Version: 2.0.1
Phone used for review: Samsung Galaxy S III


  • Free (requires subscription service or in app purchase)


  • Clinical approach of its images to simulate common imaging studies in clinical settings
  • The inclusion of multiple different modalities
  • Also the inclusion of an abundance of illustrated diagrams
  • CT images with different windows and MRIs with different sequences
  • Navigation through different images mimic real-life navigation on PAC
  • Complementary services and even more materials on IMAIOS online


  • Mildly clumsy scrolling
  • May be difficult to sort through all the data that is presented at times


  • Overall, this app is great but at a price, which is still well worth it for medical students, clinicians, surgeons, and especially radiologists
  • Rather than being an educational app, e-Anatomy serves more as a reference material and as a human atlas without any fluff that would be distracting
  • What makes e-Anatomy stand out among all the other anatomy apps is the clinical approach of its images which simulate common imaging studies encountered in real-life scenarios
  • I fully endorse IMAIOS and e-Anatomy and will be using their services heavily at least throughout my residency
