1. A computing system for processing medical imaging exams, the computing system comprising: a non-transitory computer readable medium storing one or more software modules including computer executable instructions; and one or more hardware processors in communication with the non-transitory computer readable medium and configured to execute the one or more software modules in order to cause the computing system to: receive a first medical exam including at least a 3D data set obtained by a medical imaging scanner, the first medical exam further including a first image series having a plurality of images, wherein the first image series is rendered from the 3D data set; access a rules database including a plurality of rules indicating criteria for identifying related medical exams; identify a first rule in the rules database associated with one or more characteristics of the first medical exam, the first rule including one or more first criteria for identifying a second medical exam for comparison with the first medical exam; identify the second medical exam based on the one or more first criteria of the first rule; access the second medical exam, the second medical exam including a second image series having a second plurality of images obtained by a medical imaging scanner; compare the first and second image series; determine, based on the comparison, that the first and second image series differ from one another with respect to at least scan planes associated with the respective first and second image series; in response to determining that the first and second image series differ from one another with respect to at least their respective scan planes, determine an adjustment to be made to the scan plane of the first image series such that, after the adjustment, the scan plane of the first image series matches the scan plane of the second image series; re-render, based on the adjustment, the first image series from the 3D data set of the first medical exam such that the scan plane of the re-rendered first image series matches the scan plane of the second image series; receive a selection of an image of the re-rendered first image series by a user; automatically determine an image of the second medical exam corresponding to the image of the first medical exam; automatically determine a type and location of an annotation in the image of the second medical exam; automatically add an indication of the annotation to the image of the re-rendered first image series in a location in the image of the re-rendered first image series corresponding to the location of the annotation in the image of the second medical exam, wherein the indication of the annotation is selected based on the type of the annotation; and provide the image of the re-rendered first image series, including the indication of the annotation, to a display device for display to the user.
