Equally as important as the pulse sequence used to record the data is the software used for data analysis. Ideally, fully automated spectral curve-fitting algorithms should be used to provide a quantitative estimate of each metabolite concentration. However, although such […]
One of the most promising areas of health innovation is the application of artificial intelligence AI in medical imaging, including, but not limited to, image processing and interpretation. Indeed, AI may find multiple applications, from image acquisition and processing to […]
Brain tumors remain a significant health problem in the worldwide. Overall, they comprise some of the most malignant tumors known to affect human beings and are generally refractory to all modalities of treatment. Angiogenesis underlies all tumor growth by providing […]
Perfusion is a fundamental biological function that refers to the delivery of oxygen and nutrients to tissue by means of blood flow .Perfusion MRI is sensitive to microvasculature and has been applied in a wide variety of clinical applications, including the […]
The calculation of perfusion analysis is based on measurements taken while the bolus travels through the blood system. The starting point is the arterial input function (AIF), measured at the artery before the contrast agent bolus travels through the region […]
Diffusion-weighted imaging (DWI) is a form of MR imaging based upon measuring the random Brownian motion of water molecules within a voxel of tissue. In general simplified terms, highly cellular tissues or those with cellular swelling exhibit lower diffusion coefficients. […]
Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine the brain’s functional anatomy, (determine which parts of the brain are handling critical functions), evaluate the effects […]
After designing an fMRI paradigm and running the experiment and the data collection, various analysis steps must be applied on resulting data before the neuroscientists and physicians can achieve answers to the questions about activities corresponding to the experiment. The […]
Diffusion Tensor Imaging (DTI) is an magnetic resonance imaging‑based neuroimaging technique that makes it possible to estimate the location, orientation, and anisotropy of the white matter tracts of the brain. (DTI) is an MRI technique that measures water molecule diffusion […]
DTI Analysis Techniques Many different DTI analysis techniques and approaches have been applied to study a range of pathologies and include region of interest analysis, tractography, histogram analysis, atlas-based segmentation, quantification of graph-based connectivity networks, and voxel-based analysis to name […]
