Magnetic resonance imaging (MRI), with and without contrast, has become the standard metric of finding and following lesions and axonal loss. The traditional methods of treatment include medications, diet, exercises, and neurological supportive care. The medications are limitedly effective, and often ...

A standardized pre-processing pipeline is proposed for the use of radiomics in MRI of brain tumours. For models based on first- and second-order features, we recommend normalizing images with the Z-Score method and adopting an absolute discretization approach. For second-order feature-based ...
relatively little is known about maturation of brain function during these critical times. Brain imaging provides a wealth of information on both structure and function, but limitations in technologies, such as magnetic resonance imaging (MRI) or magnetoencephalography (MEG), are exposed when attemptin...
Objective Volume isotropic simultaneous interleaved bright- and black-blood examination (VISIBLE) is a recently developed 3D MR sequence that provides simultaneous acquisitions of images with blood vessel suppression (Black) and images without it (Bright). Our purpose was to evaluate the usefulness of ...
Implement a deep learning model that provides state-of-the-art accuracy in detecting brain tumors from MRI images. 2. Integrate Grad-CAM with the deep learning model to offer visual explanations for the model’s predictions, enhancing the interpretability and trustworthiness of the AI system. ...
The SE T 1WI MT images showed significantly more lesions (60 lesions) than the routine SE T 1WI (χ 2=7 79, P 0 01) Conclusion MR imaging performed with MT appears to be more sensitive than routine SE T 1WI in the detection of small lung metastatic lesions in the brain and may ...
Multimodal machine learning studies show promise in brain aging23; however, most rely on structural magnetic resonance imaging (MRI), overlooking brain network dynamics. Complex spatiotemporal dimensions can be tracked with spatial accuracy through functional magnetic resonance imaging (fMRI) and with mill...
For validation, we applied the proposed algorithm and conventional methods to T2 infant images (0–24 months of age) acquired with 2D and 3D sequences at 3T MRI. The Dice coefficients and Precision scores, which were calculated as quantitative measures, showed the highest values for the ...
Figure 1 - Anatomy of the encephalon in MRI (axial, coronal and sagittal slices) Cerebral images used for this module on human anatomy An MRI was performed in thin slices (0.6 mm) on a healthy individual, with volumetric 3D imaging using T1 weighting without injection of gadolinium in the...
