Abstract
Methods and systems for detecting a dissection of an elongated structure in a three dimensional medical image. One system includes an electronic processor configured to receive the medical image and detect a centerline of the elongated structure. The electronic processor is configured to determine a plurality of two dimensional cross sections of the medical image based on the centerline. For each of the two dimensional cross sections, the electronic processor is configured to determine a radial density profile and determine a density gradient based on the radial density profile. The electronic processor is configured to analyze one or more of a plurality of density gradients determined for each of the two dimensional cross sections, detect a dissection in the elongated structure based on the analysis of the density gradient for each of the two dimensional cross sections, and output a medical report identifying the dissection.
