This review article aims to provide an overview on the principles of diffusion-weighted magnetic resonance imaging (DW-MRI) and its applications in the imaging of the prostate. DW-MRI with regards to different applications for prostate cancer (PCa) detection and characterization, local staging as well as for active surveillance (AS) and tumor recurrence after radical prostatectomy (RP) will be ...

Magnetic Resonance Imaging (MRI) is a versatile imaging technique that allows probing of the various properties of the soft-tissue within the body of living organisms and has been widely used for diagnostic as well as research purposes. MRI has been very useful for studying the brain as it provides an exceptional ability to study structural, functional and dynamic properties in a non-invasive f...

Brain capillary telangiectasia is an incidental vascular malformation found usually in pons and sometimes in extra- pontine sites. Typical MRI features are enhancement on post contrast T1 weighted images and signal loss on gradient echo images. We evaluated 10 patients with various MR techniques. Susceptibility weighted imaging was superior to GRE T2 in showing decreased signal due to susceptib...

Since the time that Ormerod, du Boulay, and McDonald wrote their chapter on the neuroimaging of multiple sclerosis (MS ) for the first edition of this volume, continuing advances in the field of magnetic resonance (MR) and MR imaging (MRI) have made tremendous impacts in our understanding of this disease. Over the last few years, findings from (i) “conventional” MRI techniques [e.g., T2-weighte...

Optic chiasm lesions in myelin oligodendrocyte glycoprotein (MOG)-experimental autoimmune encephalomyelitis (EAE) mice were characterized using magnetic resonance imaging (MRI) and validated using electron microscopy (EM). MR images were collected from 3 days after induction to remission, approximately 20 days after induction. Hematoxylin and eosin, solochrome cyanin-stained sections, and EM im...

Diffusion-weighted MRI is the forerunner of rapidly developed microstructure (?MRI) aimed at in vivo evaluation cellular tissue architecture. This brief review focuses on spatiotemporal scales that are accessible using different diffusion techniques and need to weight measurability against interpretability results. Diffusion phenomena models first classified two-dimensional space (the q-t-plane...

PURPOSE Diffusion contrast in diffusion-weighted steady-state free precession magnetic resonance imaging (MRI) is generated through the constructive addition of signal from many coherence pathways. Motion-induced phase causes destructive interference which results in loss of signal magnitude and diffusion contrast. In this work, a three-dimensional (3D) navigator-based real-time correction of t...

UNLABELLED BACKGROUND MRI has become the mainstay of diagnostic imaging in paediatric rheumatology for lesion detection, differential diagnosis and therapy surveillance. MR imaging of synovitis, in particular, is indispensable for early diagnosis and follow-up in arthritis patients. We used diffusion-weighted MRI (DWI) as a new imaging modality in comparison to standard MRI sequences to stud...

BACKGROUND AND PURPOSE Diffusion MRI has established value in patients with ischemic stroke but has not been systematically investigated in patients with transient ischemic attack (TIA). METHODS Clinical, conventional MRI, and diffusion MRI data were collected on 42 consecutive patients with symptoms of cerebral TIA. TIA imaging data were compared with those from a contemporaneous group of 23...

Congenital mesoblastic nephroma (CMN) is the most common renal tumor in the first year of life. Here, we present unique findings of cellular variant CMN seen on prenatal and postnatal MRI with diffusion-weighted imaging (DWI).The mass was well-visualized on prenatal MR DWI with diffusion restriction in the solid portions. After excision of the mass, follow-up whole body MRI with DWI helped iden...
