OBJECTIVE To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold (BH), respiratory-triggered (RT), and M...

Different sets of criteria are currently used for the diagnosis of multiple sclerosis (MS). Some are based on clinical features, while others are related to imaging findings. Among the image processing systems, specific criteria include spatial dissemination of lesions in one image or their temporal dissemination in images acquired at different time points. In addition, the evolution of the les...

Diffusion-weighted magnetic resonance imaging (DW-MRI) appears to hold promise as a non-invasive imaging modality in the detection of early microstructural and functional changes of different organs. DW-MRI is an imaging technique with a high sensitivity for the detection of a large variety of diseases in the urogenital tract. In kidneys, DW-MRI has shown promise for the characterization of sol...

In order to achieve its main goal of maximal tumor removal while avoiding postoperative neurologic deficits, neuro-oncological surgery is strongly dependent on image guidance. Among all currently available imaging modalities, MRI provides the best anatomic detail and is highly sensitive for intracranial pathology. However, conventional MRI does not detect the exact location of white matter trac...

Hyperpolarised 3He ventilation-MRI, anatomical lung MRI, lung clearance index (LCI), low-dose CT and spirometry were performed on 19 children (6-16 years) with clinically stable mild cystic fibrosis (CF) (FEV1>-1.96), and 10 controls. All controls had normal spirometry, MRI and LCI. Ventilation-MRI was the most sensitive method of detecting abnormalities, present in 89% of patients with CF, com...

Multiple sclerosis (MS) is a chronic disabling autoimmune disorder of the central nervous system histopathologically characterized by inflammation, multifocal demyelination, axonal damage and neuronal loss. Focal intensive demyelination and white matter infiltration by lymphocytes and mononuclear cells are pathological hallmarks of the disease (Ferguson et al., 1997; Lucchinetti et al., 2000). ...

The majority of previous studies on hereditary neuropathy with liability to pressure palsies (HNPP) were focused on peripheral nerves, whereas cerebral alterations in HNPP have been less attended to. In this work, Diffusion tensor imaging (DTI) was used to detect the changes in WM, especially in the normal-appearing white matter (NAWM) in HNPP patients for its sensitivity in probing the microst...

MRI has provided important insights into the pathophysiology of multiple sclerosis (MS).1 However, conventional MRI scans furnish only gross estimates of the nature and extent of tissue damage associated with MS,2 and the data correlate poorly with measures of concurrent disability in patients. Recent advances in MRI technology have improved the correlation of MRI findings with clinical status ...

Recent years have witnessed impressive advances in the use of magnetic resonance imaging (MRI) with varying success either to contribute to patient clinical work up aimed at establishing a diagnosis of degenerative dementia, as well as to monitor disease progression. Conventional MRI of the brain has an important role in differentiating Alzheimer Disease (AD) from other pathologies, including n...

We describe the prenatal magnetic resonance imaging (MRI) findings in a 25-week-old fetus with proven osteogenesis imperfecta type II. Fetal MRI findings are correlated with prenatal ultrasonography, conventional x-ray fetography and postpartal findings. Fetal MRI proves to be superior to conventional fetography in the evaluation of the skeletal findings. The high soft tissue resolution, the la...
