Automated wall motion quantification in aortic dissections

A computer program for processing MRI images to determine one or more characteristics of an anatomical feature, comprising instructions for:

• obtaining one or more first MRI images of the anatomical feature;
• identifying a boundary of an anatomical feature in the MRI images;
• and
• using the identified boundary to mask one or more corresponding second MRI images of the anatomical feature to isolate the anatomical feature within the second MRI images.

A computer implemented method for processing MRI images, comprising:

• displaying an MRI image including an anatomical feature;
• calculating a boundary of the anatomical feature using the MRI image;
• and
• displaying the calculated boundary of the anatomical feature overlayed onto the MRI image.

A computer implemented method for processing MRI images to diagnose an acute aortic dissection in a patient, comprising:

• obtaining an MRI image of the aorta of the patient;
• calculating a boundary of the lumen of the aorta MRI image;
• and
• determining a degree of displacement of the lumen boundary of the MRI image of the aorta during a cardiac cycle;
• and
• if the degree of displacement is greater than a threshold value, then diagnosing that the patient has an acute aortic dissection.

A computer implemented method for processing MRI images to diagnose a cerebral aneurysm in a patient, comprising:

• obtaining an MRI image of the cerebral aneurysm of the patient;
• calculating a boundary of the lumen of the cerebral aneurysm MRI image;
• and
• determining a degree of displacement of the lumen boundary of the MRI image of the cerebral aneurysm during a cardiac cycle;
• and
• if the degree of displacement is greater than a threshold value, then diagnosing that the patient has an cerebral aneurysm.
