Sensorineural Hearing Loss: Pathophysiology, Diagnosis and Treatment [Chapter 5. Neuroradiology of the Hearing System]
2019
Hearing loss is one of the most frequent indications for CT and MR examinations of the auditory system. Such a symptomatology is becoming increasingly common in today’s society and is extremely disturbing for patients. Causes may involve the auditory pathway at any level. In most cases, neuroradiological examinations represents a mandatory step, within a multidisciplinary workup, towards final diagnosis, therapeutic plan and subsequent follow-ups. This chapter will introduce this critical topic starting from an imaging-based exposition of the anatomy and function of the auditory system. The chapter will include some hints on the choice of the best imaging examination to perform on each pati…

Long-term evolution of hepatocellular adenomas at MRI follow-up
2021
Background Hepatocellular adenomas (HCAs) are rare benign liver tumors. Guidelines recommend continued surveillance of patients diagnosed with HCAs, but these guidelines are mainly based on small studies or expert opinion. Purpose To analyze the long-term evolution of HCAs, including solitary and multiple lesions, and to identify predictive features of progression with MRI. Materials and Methods In a retrospective study, patients diagnosed with pathologically proven solitary or multiple HCAs between January 2004 and December 2015 were included; β-catenin-mutated HCAs and HCAs with foci of malignancy were considered to be at risk for progression. MRI examinations were analyzed, and tumor evo…
Un metodo alternativo per l’ortoproiezione di immagini IKONOS-Geo
2005
La disponibilità di immagini satellitari ad alta risoluzione ed i risultati ottenuti nella sperimentazione delle precisioni che esse consentono fanno ipotizzare una loro futura introduzione nella prassi consolidata per la produzione di ortofoto, in alternativa alle immagini ottenute da camera aviotrasportata. E’ quindi auspicabile la messa a punto di procedure semplificate, che riducano i tempi operativi e quindi i costi. In relazione a ciò, il presente lavoro vuole fornire un contributo descrivendo la sperimentazione di un metodo di ortoproiezione innovativo. Il metodo richiede l’impiego di un numero ridotto di punti di appoggio e, nel caso sperimentato, ha permesso di raggiungere accurate…

Incisioni, immagini e architettura: alcune osservazioni
2013
Between the 16th and the 17th century Europe saw the release of an immense amount of architecture prints pursuing a practical purpose : we are dealing with models for a public of professionals and architects. Though the importance of the phenomenon has been underestimated by historiography, it reaches a noticeable size in geographical areas usually considered peripheral such like Sicily. Nowadays the digital filing systems can provide a fundamental instrument for a deeper understanding of both the users’ behaviour and the assimilation/selection mechanisms orienting the professional practice.
Neutron flux and gamma dose measurement in the BNCT irradiation facility at the TRIGA reactor of the University of Pavia
2018
Abstract University of Pavia is equipped with a TRIGA Mark II research nuclear reactor, operating at a maximum steady state power of 250 kW. It has been used for many years to support Boron Neutron Capture Therapy (BNCT) research. An irradiation facility was constructed inside the thermal column of the reactor to produce a sufficient thermal neutron flux with low epithermal and fast neutron components, and low gamma dose. In this irradiation position, the liver of two patients affected by hepatic metastases from colon carcinoma were irradiated after borated drug administration. The facility is currently used for cell cultures and small animal irradiation. Measurements campaigns have been ca…
