[Radiomics and artificial intelligence: new frontiers in medicine.]
2020
Radiomics is a new frontier of medicine based on the extraction of quantitative data from radiological images which can not be seen by radiologist's naked eye and on the use of these data for the creation of clinical decision support systems. The long-term goal of radiomics is to improve the non-invasive diagnosis of focal and diffuse diseases of different organs by understanding links between extracted quantitative imaging data and the underlying molecular and pathological characteristics of lesions. In the last decade, several studies have highlighted the enormous potential of radiomics in both tumoral and non-tumoral diseases of many organs and systems including brain, lung, breast, gast…
MRgFUS Uterine Fibroids treatments in Sicily: Preliminary Results and comparison of a Semi-Automatic and manual contouring
2013
Background: Traditional surgery for uterine fibroids treatments (e.g. myomectomy, hysterectomy) offers very invasive therapeutic approaches, which not always preserve reproductive potential of the woman. MRgFUS (MR guided Focused UltraSound) is a new and non-invasive technique for uterine fibroids treatment, not requiring hospitalization and recovery time [1]. On June 2011 and July 2012 the first treatments were started at HSR-Giglio Hospital in Cefalù and at University Hospital (DIBIMEF) in Palermo. An initial assessment of MRgFUS treatment was made by computing the thermally-ablated volume of uterine fibroid. This volume was evaluated considering the NPV (Non Perfused Volume) on a post-t…
Automatic Volumetric Liver Segmentation Using Texture Based Region Growing
2010
In this paper an automatic texture based volumetric region growing method for liver segmentation is proposed. 3D seeded region growing is based on texture features with the automatic selection of the seed voxel inside the liver organ and the automatic threshold value computation for the region growing stop condition. Co-occurrence 3D texture features are extracted from CT abdominal volumes and the seeded region growing algorithm is based on statistics in the features space. Each CT volume is composed by 230 slices, having 512 x 512 pixels as spatial resolution, and 12-bit gray level resolution. In this initial feasible study, 5 healthy volunteer acquisitions has been used. Tests have been p…
IL PURGATORIO: la cantica della nostalgia
2023
Starting from the aesthetic and critical judgments that the twentieth century expressed on the second canticle of Dante’s poem, the essay traces the most famous metaphors and images through the lens of stylistic, linguistic and thematic analysis
Teatro e narrativa di Umberto Barbaro
1992
La monografia ripercorre l'itinerario intellettuale e letterario di Barbaro. Nella prima parte sono presi in esame i suoi scritti critici e la sua produzione teatrale e narrativa degli anni Venti, legati alla stagione dell'immaginismo, quando lo scrittore condivide gli orientamenti di quel movimento verso un'arte irrealistica che, nello scarto ironico tra piano della realtà e mondo ricreato da un visionarismo fantastico e paradossale, esprime una volontà di ribaltamento dei canoni del mondo borghese (sono evidenziati anche i rapporti con altre avanguardie, e nello stesso tempo la specificità). L'aspirazione a un'arte volta ad incidere profondamente nella realtà permane in Barbaro anche quan…
Io scrivo ciò che vedo. Einmal di Wim Wenders tra immagini autocelebrative e priorità del racconto
2018
Like many of Wenders’ films, the book Una volta (Einmal. Bilder und Geschichten, 1994; Once: Pictures and Stories) is the result of a fruitful encounter between different arts. Wenders now takes on the role of photographer and narrator, while never completely abandoning the more usual role of director. The beginning of every short composition in Einmal, associated with one or more images, is the usual one of fairy tales. However, the word “once” that precedes as a title most of the compositions is not just an intertextual reference to the genre of children’s literature. It is more a sort of declaration of poetics, the choice of a specific stylistic register, as well as an attempt to adhere …

Comunicazione animalista, corporeità dell’animale e isotopia del martirio
2019
È possibile parlare di martirio al di fuori del tradizionale ambito della religione e della politica intesa in senso stretto? Può essere utile farlo, al fine di comprendere meglio i meccanismi semiotici che regolano il martirio stesso? Uno dei campi in cui si possono ritrovare i principali tratti del martirio è quello della comunicazione messa in atto da parte dei movimenti animalisti. In apparenza un’area molto lontana da quella del martirio religioso o di quello a scopi politici, ma l’animalismo è in effetti un fenomeno in cui ragioni etiche, politiche, religiose, dietetiche e filosofiche sono strettamente interconnesse. Tra l’altro, il rinnovato interesse per la semiotica dell’animalità …
