Compositions and methods for enhancing vascular integrity in animals are disclosed. The compositions and methods, which utilize long chain polyunsaturated fatty acids and nitric oxide releasing compounds are also effective for reducing ischemia-induced brain injury in an animal.

A medical imaging probe (102) for contact with an imaging subject includes an indicium placement apparatus for, while the probe is in contact, selectively performing an instance of marking the subject so as to record a position of the probe. The device may further include a feedback module for determining whether an orientation, with respect to a the mark, that currently exists for a medical imaging probe of the device meets a criterion of proximity to a predetermined orientation. Responsive to the determination that the criterion is met, a quantitative evaluation may be made automatically and without need for user intervention, via live imaging via the probe, of a lesion that was, prior to the determination, specifically identified for the evaluation. Change, such as growth (116), in the lesion, like a brain lesion, may thereby be tracked over consistent sequential imaging acquisitions, such as through ultrasound.

The invention discloses a DTI image analytical method based on multiple variables. The DTI image analytical method based on the multiple variables is used for determining and extracting diseased areas of the brain white matter in the disease brain mechanism research, thereby providing an imaging basis for clinical treatment. The method includes the specific steps that data are preprocessed, wherein the preprocessing procedures include eddy current removal, head motion correction, cranium removal, dispersing and fitting and white matter skeleton building; characteristic extraction is conducted on the preprocessed data, the significant difference areas of a patient group and a healthy people group are obtained through replacement inspection and with the ages serving as the concomitant variables, the average value of the certain variables in the significant difference areas is worked out respectively, and the characteristic value is obtained; cross validation is conducted through a leave-one-out method, whether the stop criterion is met or not is judged, and if not, the average weight value of each characteristic is worked out, and the characteristic with the minimum average weight value is removed until the stop criterion is met; the finally obtained brain area is the brain lesion area. According to the method, the DTI imaging mode is adopted, the imaging basis is provided for finding the lesion area in the clinical treatment through the multivariable research method.
