Anatomia e patologia del labirinto membranoso studio con sequenze RM sensibili al flusso

1994

Nonostante i deludenti esordi nella valutazione delle strutture labirintiche costituenti l'orecchio interno, la risonanza magnetica costituisce oggi, grazie anche al miglioramento dell'hardware e del software disponibili, una modalità diagnostica di grande efficacia non solo nell'analisi della patologia espansiva o infiammatoria coinvolgente il VII ed VIII nervo cranico, ma anche nella valutazione delle alterazioni patologiche del segnale endolabirintico in rapporto a focolai emorragici o, come recentemente dimostrato mediante uso di Gd-DTPA, nell'analisi delle alterazioni a carico della capsula oticanella fase spongiotica dell'otosclerosi. Tuttavia, lo scarso contrasto esistente tra liqui…

MRI findings and evoked potentials in patients with myotonic dystrophy versus facioscapulohumeral dystrophy

1997

Evoked potentials recordings have been applied to many neurological disorders, localizing the lesions in the central nervous system (CNS) pathways. Facioscapulohumeral muscular dystrophy (FSHD) is a slowly progressive degenerative disease involving the muscles of the face and shoulders. On the contrary, myotonic distrophy (MD), the most frequent and severe myotonic disease, is caracterized by myotonia (delay of relaxation after voluntary contraction), muscular atrophy and dystrophic changes in non-muscular tissues. In the present investigation, patients with clinically and electromyographically verified FSHD and MD were examined using somatosensory evoked potentials (SEP) and brainstem aud…

Valutazione comparativa delle sequenze fast Spin-echo e Spin-echo T2-dipendenti nella dimostrazione delle lesioni demielinizzanti encefaliche in cors…

1997

We compared T2-weighted fast spin-echo (FSE) magnetic resonance (MR) imaging and conventional spin-echo (CSE) T2-weighted imaging in the detection of brain lesions of multiple sclerosis (MS). 20 patients with clinically definite MS underwent brain imaging with both FSE and CSE T2-weighted imaging. There was no significant difference in total number of lesions detected on FSE vs CSE (1354 vs 1378). Slightly more periventricular and subcortical lesions were detected using CSE than FSE, whereas more posterior cranial fossa lesions were detected by FSE. There was no statistically significant difference in the signal intensity (SI) ratio of MS lesions to that of surrounding normal white matter …

Orbital varices: a tricky diagnosis in MRI

1995

Orbital varix (OV) is a rare condition causing intermittent positional exophthalmos. Because of low venous pressure, OVs tend to collapse, being frequently undetectable in routine CT or MRI examinations. We describe one case of giant intraorbital varix studied with CT and MRI techniques.
