Context.Optical long-baseline interferometry is moving a crucial step forward with the advent of general-user scientific instruments that equip large aperture and hectometric baseline facilities, such as Very Large Telescope Interferometer (VLTI).
The purpose of this study is to describe the main chest radiological features (CXR) COVID-19 and correlate them with clinical outcome.This a retrospective involving patients clinical-epidemiological suspect infection, who performed CXRs at emergency department (ED) our University Hospital from March 1 31, 2020. All RT-PCR nasopharyngeal throat swab, CXR ED data. results were considered reference standard. final outcome was expressed as discharged or hospitalized into medicine intensive care...
Aims.In this paper, we present an innovative data reduction method for single-mode interferometry. It has been specifically developed the AMBER instrument, three-beam combiner of Very Large Telescope Interferometer, but it can be derived any interferometer.
Abstract Objectives The aim of this single-centre, observational, retrospective study is to find a correlation using Radiomics between the analysis CT texture features primary lesion neuroendocrine (NET) lung cancer subtypes (typical and atypical carcinoids, large small cell carcinoma), Ki-67 index presence lymph nodal mediastinal metastases. Methods Twenty-seven patients (11 males 16 females, aged 48 81 years old—average age 70,4 years) with histological diagnosis pulmonary NET known status...
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...
Aims. We present the first NIR spectro-interferometry of LBV η Carinae. The observations were performed with AMBER instrument ESO Very Large Telescope Interferometer (VLTI) using baselines from 42 to 89 m. aim this work is study wavelength dependence Car's optically thick wind region a high spatial resolution 5 mas (11 AU) and spectral resolution.
The young stellar object MWC 297 is an embedded B1.5Ve star exhibiting strong hydrogen emission lines and a near-infrared continuum excess. This has been observed with the VLT interferometer equipped AMBER instrument during its first commissioning run. AMBER/VLTI currently only near infrared that can observe spectrally dispersed visibilities. spatially resolved in visibility of as well Brγ line where decreases to . change wavelength be interpreted by presence optically thick disk responsible...
The aims of our study are: (1) to estimate admission chest X-ray (CXR) accuracy during the descending phase pandemic; (2) identify specific CXR findings strictly associated with COVID-19 infection; and (3) correlate lung involvement patients' outcome. We prospectively evaluated 327 patients accessed institute Italian pandemic (April 2020). For each were searched ground glass opacification (GGO), consolidation (CO), reticular-nodular opacities (RNO), nodules, excavations, pneumothorax,...
Context. Interferometry can provide spatially resolved observations of massive star binary systems and their colliding winds, which thus far have been studied mostly with unresolved observations.
Aims.We investigate the origin of emission Herbig Ae star HD 104237 on Astronomical Unit (AU) scales.
Aims.We study the geometry and kinematics of circumstellar environment Be star κ CMa in Brγ emission line its nearby continuum.
Purpose To evaluate the dependence on b‐values adopted of apparent diffusion coefficient (ADC), perfusion fraction (PF), slow and fast (D , D ), corrected (D) kurtosis (K), in healthy peripheral (HP) cancerous (PCa) prostate tissues. Materials Methods Patients who underwent multiparametric MR examination were retrospectively evaluated for possible inclusion. ADC, PF, D, K estimated both HP PCa tissues, using three different ranges b‐values: 0–2300, 0–1800, 0–800 s/mm 2 (group A, B C,...
Background: Rectal cancer represents a major cause of mortality in the United States. Management strategies are highly individualized, depending on patient-specific factors and tumor characteristics. The therapeutic landscape is rapidly evolving, with notable advancements response rates to both radiotherapy chemotherapy. For locally advanced rectal (LARC, defined as up T3–4 N+), standard care involves total mesorectal excision (TME) following neoadjuvant chemoradiotherapy (nCRT). Magnetic...
Rectal cancer is a major mortality cause in the United States (US), and its treatment based on individual risk factors for recurrence each patient. In patients with rectal cancer, accurate assessment of response to chemoradiotherapy has increased importance as variety options grown. this scenario, controversial non-operative approach may be considered some whom complete tumor regression believed have occurred. The recommended locally advanced (LARC, T3-4 ± N+) total mesorectal excision (TME)...
To prospectively verify, in vivo, Le Bihan's model of signal decay magnetic resonance/diffusion-weighted imaging (intravoxel incoherent motion) healthy liver parenchyma.Informed consent and institutional board approval were obtained. measure both underfasting postprandial conditions, apparent, slow, fast diffusion (D*) coefficients perfusion fraction parenchyma, 40 volunteers (19 women 21 men) underwent a 3.0-T resonance examination, including portal venous flow measurements by 2-dimensional...
ABSTRACT BACKGROUND AND PURPOSE The role of apparent diffusion coefficient (ADC) for preoperative grading and treatment planning high‐grade gliomas (HGG) is still debated since the assumption inverse correlation between ADC cellularity not completely coherent with results some studies. It has been recently hypothesized that restricted diffusivity in HGG may be related to hypoxic/ischemic changes inside tumor. We therefore investigated differences values areas magnetic resonance spectroscopy...
Abstract Purpose Cerebrovascular disease (CVD) is considered a major risk factor for fatal outcome in COVID-19. We aimed to evaluate the possible association between computed tomography (CT) signs of chronic CVD and mortality infected patients. Materials methods performed double-blind retrospective evaluation cerebral CT scans 83 COVID-19 patients looking CVD. developed rapid visual score, named CVD-CT, which summarized presence parietal calcifications dolichosis, with or without ectasia,...
