MR imaging of neuronal migrational disorders.
Neuronal migrational disorders of the brain represent abnormalities in the formation of the neocortex caused by faulty migration of the subependymal neuroblasts. These migrational anomalies include lissencephaly (agyria/pachygyria), pachygyria, schizencephaly, heterotopias, hemimegalencephaly, and polymicrogyria. We used MR imaging (performed on a 0.5-T or 1.5-T scanner) to evaluate 21 patients...
متن کاملDisorders of cortical formation: MR imaging features.
The purpose of this article was to review the embryologic stages of the cerebral cortex, illustrate the classification of disorders of cortical formation, and finally describe the main MR imaging features of these disorders. Disorders of cortical formation are classified according to the embryologic stage of the cerebral cortex at which the abnormality occurred. MR imaging shows diminished cort...
متن کاملMR imaging illuminates elbow joint disorders
MRI has become the secondary procedure of choice, after plain-film x-ray, for evaluating elbow abnormalities. The modality can visualize ligament and tendon injuries, compressive or entrapment neuropathy, bone injuries, inflammatory and synovial conditions, and soft-tissue masses. Congenital abnormalities in the elbow are rare. The most common is radial head dislocation, which may affect one or...
متن کاملMR neurography and muscle MR imaging for image diagnosis of disorders affecting the peripheral nerves and musculature.
Recent advances in the technology of MR imaging are beginning to transform the fundamental methodology of diagnostic evaluations in neuromuscular disorders. When properly implemented, MR neurography is capable of providing high-quality information about nerve compression, nerve inflammation, nerve trauma, systemic neuropathies, nerve tumors, and recovery of nerve from pathologic states. Muscle ...
متن کاملMuscle MR Imaging in Tubular Aggregate Myopathy
PURPOSE To evaluate with Magnetic Resonance (MR) the degree of fatty replacement and edematous involvement in skeletal muscles in patients with Tubular Aggregate Myopathy (TAM). To asses the inter-observer agreement in evaluating muscle involvement and the symmetry index of fatty replacement. MATERIALS AND METHODS 13 patients were evaluated by MR to ascertain the degree of fatty replacement (...
