TERAPIA TRANS-CRANICA AD ULTRASUONI FOCALIZZATI GUIDATI DA RISONANZA MAGNETICA UTILIZZANDO UN SISTEMA INTEGRATO CON UNO SCANNER RM DA 1.5T
2019
Scopo Negli ultimi anni la terapia transcranica ad ultrasuoni focalizzati guidati da risonanza magnetica (tcMRgFUS) per il trattamento di disordini neurologici quali il tremore essenziale (ET) e il Parkinson tremorigeno (PD) è stata effettuata utilizzando esclusivamente scanner RM da 3T. Presentiamo i risultati ottenuti con il primo sistema tcMRgFUS mai integrato con uno scanner RM da 1.5T. Materiali e metodi 50 pazienti (39 ET; 11 PD) sono stati selezionati per essere sottoposti a tcMRgFUS (talamotomia monolaterale; target: nucleo ventrale intermedio, VIM). I pazienti arruolati sono stati valutati prima del trattamento e 2 giorni dopo. L'efficacia del trattamento è stata valutata utilizzan…
Vantaggi degli ultrasuoni nel posizionamento di un agocannula nella vena giugulare interna (nuove note di tecnica)
2004
The authors analized the result of 175 central venous ca he- terization CVC. of internal jugular vein performed with the ultrasound guide (US) from January 1998 to October 2002. The average performing time was 45 minutes. 98.2% of success and 4% of complications (one pagal hypotension, one artery puncture, four catheter dislocation, one haeiuatoinai). The US guide CVC is a safe procedure with short performing time, low rate of failures and complications and high rate of success: it is helpful in all patients with vascular anatomical variations, with not visualized or Land marks and with coagulation disorders.

Impact of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in multislice computed tomography coronary angiography.
2005
PURPOSE: To assess the effect of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in the detection of significant coronary artery stenosis using 16-row multislice computed tomography (MSCT). MATERIALS AND METHODS: One hundred patients (88 males; 59+/-11 years) with suspected coronary artery disease who had undergone conventional coronary angiography (CA) and MSCT-CA were retrospectively enrolled for the study. Patients underwent a MSCT-CA, with the following protocol: collimation 16x0.75 mm, gantry rotation time 420 ms, feed/rotation 2.8 mm, kV 120, mAs 400-500. The protocol for contrast material administration was 100 ml of Iodixanol 320 mgI/ml at 4 ml/s and …
