High-resolution diffusion-weighted brain MRI under motion [PDF]

open access: yes, 2014
Magnetic resonance imaging is one of the fastest developing medical imaging techniques. It provides excellent soft tissue contrast and has been a leading tool for neuroradiology and neuroscience research over the last decades.

Diffusion-Weighted Magnetic Resonance Imaging

open access: yes, 2018
Magnetic resonance imaging (MRI) is a technique based on the contents and relaxation features of water in tissues. In basic MRI sequences, diffusion phenomenon of water molecules is not taken into account although it has a notable influence in the relaxation times, and therefore in the signal intensity of images.

Advances in Diffusion-Weighted Imaging [PDF]

open access: yesRadiologic Clinics of North America, 2015
Diffusion-weighted imaging (DWI) has become a routine component of clinical MR imaging. Its unique soft tissue contrast mechanism exploits differences in the motion of water molecules in vivo at a biologically meaningful scale. The clinical potential of DWI in lesion detection, characterization, and response assessment has been explored.

Potential use of oxygen as a metabolic biosensor in combination with T2*-weighted MRI to define the ischemic penumbra [PDF]

open access: yes, 2008
We describe a novel magnetic resonance imaging technique for detecting metabolism indirectly through changes in oxyhemoglobin:deoxyhemoglobin ratios and T2* signal change during ‘oxygen challenge’ (OC, 5 mins 100% O2). During OC, T2* increase reflects O2

MRI of Breast Lymphoma: A Report of Two Cases with Emphasis on Diffusion Weighted Imaging and Apparent Diffusion Coefficient Value [PDF]

open access: yesMiddle East Journal of Cancer, 2019
Breast lymphoma is a rare neoplasm that accounts for approximately 0.04-0.5% of breast malignancies. Most breast lymphomas are B-cell type non-Hodgkin lymphomas. The imaging features of breast lymphoma on mammography and ultrasound are nonspecific. There

Diagnosis of pericardial cysts using diffusion weighted magnetic resonance imaging: A case series

open access: yesJournal of Medical Case Reports, 2011
Introduction Congenital pericardial cysts are benign lesions that arise from the pericardium during embryonic development. The diagnosis is based on typical imaging features, but atypical locations and signal magnetic resonance imaging sequences make it ...

Therapeutic response of immunoglobulin 4-related aortitis and pancreatitis demonstrated by diffusion-weighted MRI

open access: yesRadiology Case Reports, 2019
Immunoglobulin (IgG) 4-related disease is a systemic inflammatory disease, and it affects vascular system as aortitis, periaortitis, or aneurysm. However, due to a lack of serum biomarker on aortic damage and the multiorgan involvement, it is difficult ...

Comparison of apparent diffusion coefficient in diffusion-weighted magnetic resonance imaging and morphological assessment of breast tumors

open access: yesPolish Journal of Pathology, 2017
The aim of the study was to assess the relationship between the apparent diffusion coefficient in diffusion-weighted magnetic (DWM) resonance imaging (MRI) and selected morphological parameters of the breast lesions.
