DOI: 10.1002/mrm.27948
Abstract: Local specific absorption rate (SAR) cannot be measured and is usually evaluated by offline numerical simulations using generic body models that of course will differ from the patient's anatomy. An additional safety margin is needed… read more here.

DOI: 10.1002/nbm.4854
Abstract: Expert consensus recommends linear‐combination modeling (LCM) of 1H MR spectra with sequence‐specific simulated metabolite basis function and experimentally derived macromolecular (MM) basis functions. Measured MM basis functions are usually derived from metabolite‐nulled spectra averaged across… read more here.

DOI: 10.1007/s00062-020-00959-2
Abstract: The anatomy of the circle of Willis (CoW), the brain’s main arterial blood supply system, strongly differs between individuals, resulting in highly variable flow fields and intracranial vascularization patterns. To predict subject-specific hemodynamics with high… read more here.

DOI: 10.1007/s11682-017-9702-2
Abstract: The need for algorithms that capture subject-specific abnormalities (SSA) in neuroimaging data is increasingly recognized across many neuropsychiatric disorders. However, the effects of initial distributional properties (e.g., normal versus non-normally distributed data), sample size, and… read more here.
