Combining rheology and MRI: Imaging healthy and tumorous brains based on mechanical properties.

Purpose: It is well known that pathological changes in tissue alter its mechanical properties. This holds also true for brain tissue. In case of the brain, however, obtaining information about these properties is hard due to the surrounding cranial bone.

Acoustic radiation force contrast in MRI: detection of calcifications in tissue-mimicking phantoms.

Purpose: Mammography is a widely used tool for the screening of breast cancer, and calcifications are a common finding in most mammograms. The location, size, number, morphology, and distribution of calcifications are an important information to differentiate a benign lesion from probably malignant pathologies. Calcifications are not detectable with a standard dynamic contrast enhanced breast MRI.
