As of March 12th Italy has the largest number SARS-CoV-2 cases in Europe as well outside China. The infections, first limited Northern Italy, have eventually spread to all other regions. When controlling an emerging outbreak infectious disease it is essential know key epidemiological parameters, such basic reproduction R0, i.e. average secondary infections caused by one infected individual during his/her entire period at start outbreak. Previous work been assessment R0 analyzing data from...
The ITER project requires additional heating by two neutral beam injectors, each accelerating to 1 MV a 40 A of negative deuterium ions, deliver the plasma power about 17 MW for one hour. As these requirements have never been experimentally met, it was recognized as necessary setup test facility, PRIMA (Padova Research on Megavolt Accelerator), in Italy, including full-size ion source, SPIDER, and prototype whole injector, MITICA, aiming develop injectors be installed ITER. This realization...
Objectives The decay of 90Y has a minor branch to the O+ first excited state 89Zr, de-excitation which fundamental is followed by β+–β− emission that been used recently for biodistribution assessment after selective internal radiotherapy (SIRT) treatments. purpose present study demonstrate feasibility PET imaging dose radioembolization with microspheres. Methods Activity quantification was validated through preliminary phantom studies using cylindrical body composed six inserts different...
Purpose To propose a magnetic resonance imaging (MRI) quality assurance procedure that can be used for multicenter comparison of different MR scanners quantitative diffusion-weighted (DWI). Materials and Methods Twenty-six centers (35 with field strengths: 1T, 1.5T, 3T) were enrolled in the study. Two DWI acquisition series (b-value ranges 0–1000 0–3000 s/mm2, respectively) performed each scanner. All acquisitions by using cylindrical doped water phantom. Mean apparent diffusion coefficient...
Abstract In this article, a three‐dimensional inversion recovery sequence was optimized with the aim of generating in vivo volume T 1 maps heart using 1.5‐T MR system. Acquisitions were performed before and after gadolinium diethylenetriamine penta‐acetic acid (Gd‐DTPA) administration one patient hypertrophic cardiomyopathy two healthy volunteers. Data acquired multishot fast field echo readout both ECG respiratory triggers. A dedicated phantom, composed four solutions different values,...
Odontoid fracture is a very common cervical injury, especially in elderly patients. Despite the high frequency, appropriate management still debated. The aim of this study to evaluate clinical and radiological outcomes after anterior screw fixation or halo vest (HV) type II odontoid patients.Between January 2013 December 2015, 135 consecutive patients affected by process were found. According inclusion exclusion criteria, 57 included study. Patients evaluated with visual analog scale (VAS),...
The potential for a radiological or nuclear attack has been widely acknowledged in the last two decades. use of dirty bomb by terrorist organizations is considered to be credible threat which policymakers and relevant security agencies must prepare. Radioactive materials are stored thousands facilities around world may not adequately protected against theft. This article analyzes hypothetical large metropolitan area, evaluating radiation dose involved population. dispersion radioactive...
Over time, exposure to cerebrovascular risk factors and carotid artery disease may cause multiple asymptomatic brain cortical subcortical microinfarcts, which are commonly found at autopsy. So far, lack of convenient neuroimaging tools limited the investigation grey matter ischemic damage in vivo. We applied Double Inversion Recovery (DIR) sequence explore impact on intracortical lesion load vivo, taking into account demographic characteristics vascular factors.DIR was acquired 62 patients...
Implants' stability, especially in osteoporosis patients, is a challenging matter. Nowadays, the adoption of cannulated fenestrated screws augmented with polymethylmethacrylate cement (PMMA CSF) described by some authors. This single-center, retrospective observational study aims to evaluate long-term effectiveness, reliability, and mechanical performances this type osteoporotic fractures.All patients surgically treated from January 2009 December 2019 PMMA CSF were evaluated submitted...
Abstract Objective: To assess the impact of nonuniform dose distribution within lesions and tumor-involved organs patients receiving Zevalin(®), to discuss possible implications equivalent uniform biological effective doses (EU-BED) on treatment efficacy toxicity. MATLAB™ -based software for voxel-based dosimetry was adopted this purpose.Eleven from seven with either indolent or aggressive non-Hodgkin lymphoma were analyzed, along four disease. Absorbed estimated by a direct integration...
We study the radiation environment in MITICA, prototype of ITER neutral beam injector, during deuterium operation. is a scientific challenge: one several critical issues to solve compatibility ionizing diagnostics components placed near plasma vessel. In fact, non negligible fluxes neutrons and photons are expected from deuterium-deuterium reactions, also major peripheral component such as Neutral Beam Injector. After evaluating results Monte Carlo simulations on environment, we determine...
Nonosteoporotic burst vertebral fracture could commonly be treated with conservative or surgical approach. Currently, decision-making process is based on thoracolumbar (TL) AO spine severity injury score. However, some factors affect posttraumatic kyphosis (PTK) and taken into account. The aim of the present study to identify if axial sagittal shape initial are risk for PTK.All consecutive patients between 2016 2017 TL treatment were retrospectively evaluated in study. Only type A3 A4...
Aim of the present article was to perform three-dimensional (3D) single photon emission tomography-based dosimetry in radioimmunotherapy (RIT) with (90)Y-ibritumomab-tiuxetan. A custom MATLAB-based code used elaborate 3D images and compare average doses lesions organs at risk (OARs) those obtained planar (2D) dosimetry. Our procedure validated through preliminary phantom studies using a body consisting lung insert six spheres various sizes. In study, accuracy dose determination our imaging...
This large multicenter study of 37 magnetic resonance imaging scanners aimed at characterizing, for the first time, spatial profiles inaccuracy (namely, Δ-profiles) in apparent diffusion coefficient (ADC) values with varying acquisition plan orientation and weighting gradient direction, using a statistical approach exploiting unsupervised clustering analysis. A diffusion-weighted (DWI) protocol (b-value: 0-200-400-600-800-1000 s mm
