The present invention relates to a method for segmenting a digital image, for example to accurately segment cerebral vasculature on MRI-TOF images of a brain. The method first uses a model that imitates the perception of luminance contrasts by a human observer to accentuate a contrast between structures of interest, such as cerebral vasculature, and the image background. Then, the image is thresholded using an adaptive threshold. This enhanced segmentation method can be used to process digital images before launching further machine-implemented characterizations of the structures of interest, such as detecting and characterizing bifurcations of the cerebral vasculature for intra-cranial aneurysm prediction.

Technics are known to use vessel bifurcations detection to obtain access to the detection of aneurysms. However, such technics suffer from a relatively poor accuracy. Therefore, the Applicants have developed a specific method for locating and characterizing bifurcations of a cerebral vascular tree based on a graph analysis of a three-dimensional skeleton of the tree. This enables to determine more accurately the vessel bifurcations. Such property can be used advantageously for several applications such as predicting the risk of developing an aneurysm, diagnosing an aneurysm, identifying a therapeutic target, identifying a biomarker or screening a compound.

Abrégé
The present invention relates to hydroxy-bisphosphonic acid derivatives corresponding to general formula (I): in which: - n and m denote, independently of one another, an integer ranging from 1 to 4, - X denotes an oxygen atom or an N-R3 group, - R1 and R3 denote, independently of one another, a linear or branched C1 to C6 alkyl group, and - R2 denotes a residue of a molecule of therapeutic or diagnostic interest, or pharmaceutically acceptable salts of said derivatives, and also the method for the preparation thereof and the therapeutic or diagnostic use thereof.

Abrégé
The present invention relates to a method for preparing a hydroxy-bisphosphonic acid derivative or a salt thereof, from the corresponding carboxylic acid, comprising the following steps: - activation of the carboxylic acid function in the form of the boronate derivative thereof through the action of a borane, then - reaction with tris(trimethylsilyl)phosphite, under Arbuzov conditions - treatment with an alcohol, chosen in particular from an aliphatic alcohol or trifluoromethanol, and - separation of the hydroxy-bisphosphonic acid derivative formed, from the reaction medium.
