Magnetic Resonance Imaging findings in Primary Extracutaneous Melanoma from a Tertiary Cancer Care Centre: A Retrospective Cohort Study [PDF]

Journal of Clinical and Diagnostic Research, 2022
Introduction: Extracutaneous melanomas are rare, aggressive type of tumour, clinically and biologically distinct from their cutaneous counterpart. The two large broad categories of the extracutaneous melanomas are ocular and mucosal subtypes.

Radiomics Assessment of Bladder Cancer Grade Using Texture Features from Diffusion-Weighted Imaging

Journal of Magnetic Resonance Imaging, 2017
To 1) describe textural features from diffusion‐weighted images (DWI) and apparent diffusion coefficient (ADC) maps that can distinguish low‐grade bladder cancer from high‐grade, and 2) propose a radiomics‐based strategy for cancer grading using texture ...

Diffusion-weighted imaging in acute demyelinating myelopathy [PDF]

, 2011
Diffusion-weighted imaging (DWI) has become a reference MRI technique for the evaluation of neurological disorders. Few publications have investigated the application of DWI for inflammatory demyelinating lesions. The purpose of the study was to describe

The clinical utility of diffusion-weighted imaging in spinal infection

Clinical Neuroradiology, 2018
PurposeBoth laboratory markers and radiographic findings in the setting of spinal infections can be nonspecific in determining the presence or absence of active infection, and can lag behind both clinical symptoms and antibiotic response.

Super-Resolution in Diffusion-Weighted Imaging [PDF]

, 2011
Diffusion-weighted imaging (DWI) enables non-invasive investigation and characterization of the white-matter but suffers from a relatively poor resolution. In this work we propose a super-resolution reconstruction (SRR) technique based on the acquisition of multiple anisotropic orthogonal DWI scans. We address the problem of patient motions by aligning

Two cases of oligometastatic castration‐resistant prostate cancer detected by diffusion‐weighted whole‐body imaging with background body signal suppression

IJU Case Reports, 2020
Introduction Treatment for oligometastasis in prostate cancer has changed from systemic therapy to metastatic lesion‐targeted therapy. Early detection of metastatic lesions and assessment of the treatment response have become very important.

Imaging of Hepatocellular Carcinoma by Computed Tomography and Magnetic Resonance Imaging: State of the Art [PDF]

, 2009
Hepatocellular carcinoma (HCC) is a very frequent tumor worldwide. Its incidence is linked to the distribution of liver cirrhosis and viral hepatitis, which are the main risk factors for the development of HCC.

Diffusion weighted imaging in the liver

World Journal of Gastroenterology, 2010
Diffusion weighted magnetic resonance imaging (DWI) is an imaging technique which provides tissue contrast by the measurement of diffusion properties of water molecules within tissues. Diffusion is expressed in an apparent diffusion coefficient (ADC), which reflects the diffusion properties unique to each type of tissue. DWI has been originally used in

Outlier Rejection for Diffusion Weighted Imaging [PDF]

, 2007
This paper introduces an outlier rejection and signal reconstruction method for high angular resolution diffusion weighted imaging. The approach is based on the thresholding of Laplacian measurements over the sphere of the apparent diffusion coefficient profiles defined for a given set of gradient directions. Exemplary results are presented.

Fiber tracking in q-ball fields using regularized particle trajectories [PDF]

, 2005
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel.
