Evaluation of supraspinatus tendon teras with elastosonography in comparison to US and MRI . Our experience

INTRODUCTION: Elastosonography is a new promising ultrasound tool that can evaluate soft-tissue elasticity, in particular of the tendons. The purpose of this study was to value the elasticity of the supraspinatus tendon in shoulders with clinically suspected unilateral rotator cuff tear, and to compare the findings with those of US and MRI. MATHERIALS AND METHODS: 36 shoulders of 18 patients (mean age 46 years; range: 32 – 58 years) were examined by Elastosonography using the EUB – Hitachi 7500 Japan. Electronic array transducer of 13 MHz was used. By Elastosonography, we have evaluated the tendon fibers with a seminquantitative score of different colors representing stiff tissue (blue) to …

Plantar fascia evaluation with a dedicated magnetic resonance scanner in weight-bearing position: our experience in patients with plantar fasciitis and in healthy volunteers.

Purpose. This study assessed the usefulness of upright weight-bearing examination of the ankle/hind foot performed with a dedicated magnetic resonance (MR)imaging scanner in the evaluation of the plantar fascia in healthy volunteers and in patients with clinical evidence of plantar fasciitis. Materials and methods. Between January and March 2009, 20 patients with clinical evidence of plantar fasciitis (group A) and a similar number of healthy volunteers (group B) underwent MR imaging of the ankle/hind foot in the upright weight-bearing and conventional supine position. A 0.25-Tesla MR scanner (G-Scan, Esaote SpA, Genoa, Italy) was used with a dedicated receiving coil for the ankle/hind foot…

Valutazione della fascia plantare con una RM dedicata in posizione ortostatica: esperienza preliminare in pazienti con fascite plantare ed in volontari sani

Obiettivo/Introduzione: Dimostrare l’utilità dell’esame sotto carico della caviglia eseguito con una macchina RM dedicata nella valutazione della fascia plantare in volontari sani ed in pazienti con evidenza clinica di fascite plantare. Materiali e Metodi: Due gruppi di 20 soggetti l’uno sono stati studiati mediante esame RM, eseguito nel periodo compreso tra Gennaio e Marzo 2009. Usando una bobina ricevente dedicata, abbiamo acquisito immagini spin echo T1 (SE-T1), 3D-steady state (3D-SSF) e short tau inversion recovery (STIR) mediante macchina RM da 0,25 Tesla (G-Scan, Esaote SpA, Genova, Italia), sia in posizione ortostatica che supina convenzionale. Risultati: In tutti i volontari sani …

MR imaging of bilateral paramedian thalamic and mesencephalic infarcts: A case report

We describe MR imaging of bilateral infarction of the paramedian portion of the mesencephalus and thalamus due to an occlusion of the Percheron artery. This entity is due to one of the anatomic variants of the perforating arteries supplying the thalamus and mesenchephalus. Clinically this kind of infarction presents with neurologic impairment as a disorder of consciousness, memory dysfunctions, various types of vertical gaze palsy and psychic changes, which need to be differentiated from delirium and coma. At MRI evaluation infarction of the paramedian portion of thalami and midbrain, with a “butterfly wings” pattern, was demonstrated as high signal intensity areas on FLAIR and FSE-T2W ima…
