This invention discloses a method and
system for assessing postoperative abdominal organ
ischemia risk based on
image analysis, belonging to the field of
image analysis technology. The method includes acquiring enhanced
abdominal CT images of the target patient and outputting them after
standardization processing; employing an improved 3D U-Net++ architecture with multi-task collaborative learning to jointly segment the target patient's organs and target regions, integrating geometric priors and topological
inference mechanisms; its key technical points are: using multi-
task segmentation to focus RPPR calculation on the real ischemic area, avoiding average
dilution of the
signal across all organs, and topological correction to ensure that vascular features reflect the real
anatomy; furthermore, through the
joint analysis of low-
perfusion area prediction masks and vascular VTIF, it reveals two ischemic subtypes: structural
occlusion and functional hypoperfusion, promoting the individualization of clinical intervention strategies and defining the necessary vascular intervention or
conservative treatment, making the overall solution both innovative and clinically applicable.
