Mamourian A, Lembo J. Top Ten MR Artifacts: Radiology Boards Prep. Oxford; 2015; free on iTunes

Dr. Alex Mamourian has provided interested readers a free application through iTunes, entitled Top Ten MR Artifacts: Radiology Boards Prep, which can be downloaded on your iPad or IPhone. This e-book application describes and illustrates these artifacts: chemical shift, Gibbs effect, ghosting, susceptibility, wraparound, flow artifacts, Venetian blind effect, RF leak, incomplete chemical suppression, and entry slice. What one sees in each instance is an example of a certain MR artifact and then a single multiple-choice question asking what type of artifact it is. The artifact is then explained with other similar examples. A discussion of the artifact and methods to combat these artifacts follows. In addition, some of the images are coded in such a way that you can open up a full stack of images related to the primary image in question. Overall, this is a very nice application to store in your book file on your iPhone and have it ready for a quick consultation. The information is relevant to our daily practice and, moreover, you can’t beat the price.
