A method and system for linking position location information between two-dimensional (2D) and three-dimensional (3D) software applications for viewing diagnostic medical images. The position location information is integrated between 2D and 3D viewing paradigms. This integration provides bidirectional communication between the 2D and 3D viewing paradigm systems. The 3D cursor allows for immediate synchronized navigation through different image sets such as 3D magnetic resonance (MR) images and 2D computed tomography (CT) images while they are being simultaneously viewed on the two different viewing applications.
