A computer-implemented method for classifying and presenting a contrast phase (CP) of a contrast enhanced computerized tomography (CECT) scan is provided. The method includes training an artificial intelligence (AI) algorithm utilizing a set of CPs labeled CECT data to associate a set of characteristics of the data with a probability associated with the CP. The method includes receiving a new set of unlabeled CECT data, and applying the AI algorithm to the new unlabeled CECT data to associate a first probability of a first CP and a second probability of a second CP. The method also includes providing a graphical representation including the first probability of the first CP and the second probability of the second CP.

Method of determining contrast phase of a computerized tomography image

Systems and methods are provided for recognizing pathological images captured by alternate image capturing devices. In embodiments, a computer-implemented method includes: obtaining, by a computing device, a classifier generated based on a plurality of standardized training pathology images associated with a known classification and generated by a first type of device; receiving, by the computing device, an alternate pathology image captured by a second type of device; standardizing, by the computing device, the alternate pathology image; determining, by the computing device, a classification of the alternate pathology image based on applying the generated classifier; and outputting, by the computing device, information regarding the determined classification to aid in diagnosis of a medical condition represented by the alternate pathology image.

Recognizing pathological images captured by alternate image capturing devices

Mechanisms are provided for determining a measure of radiodensity of anatomical structures of interest and classifying medical imaging study data structures (studies) with regard to contrast phase. In some embodiments, this classification may be used to select/exclude slices for processing by other downstream computing systems. A subset of slices are selected from the study and, for each slice in the subset, a corresponding body part regression (BPR) score is determined. A linear regression on the BPR scores is performed and a representative slice is selected based on results of the linear regression. The representative slice is segmented and a statistical measure of a radiodensity metric for each segment in the representative slice is determined.
