Improved Upper Limit on the Neutrino Mass from a Direct Kinematic Method by KATRIN.

We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are energy analyzed by a high-resolution MAC-E filter. A fit of the integrated electron spectrum over a narrow interval around the kinematic end point at 18.

Software-assisted quantitative analysis of small bowel motility compared to manual measurements.

Aim: To validate a newly developed software prototype that automatically analyses small bowel motility by comparing it directly with manual measurement.

Material And Methods: Forty-five patients with clinical indication for small bowel magnetic resonance imaging (MRI) were retrospectively included in this institutional review board-approved study. MRI was performed using a 1.

Software-supported evaluation of gastric motility in MRI: a feasibility study.

Introduction: The aim of this study was to evaluate the feasibility of dedicated motility assessment software for quantitative evaluation of basic gastric motility and to validate it using manual measurements.

Methods: Ten patients (5 males/5 females, mean 41 years) out of a previous series of small bowel MR-enterography examinations with well visible stomachs were included in this Institutional Reviews Board approved, retrospective study. MRI (1.

Differentiation between active and chronic Crohn's disease using MRI small-bowel motility examinations - initial experience.

Aim: To evaluate the influence of locally active Crohn's disease on systemic small-bowel motility in patients with chronic Crohn's disease compared to healthy individuals.

Material And Methods: Fifteen healthy individuals (11 men, four women; mean age 37 years) and 20 patients with histopathologically proven active (n = 15; 10 women, 5 men; mean age 45 years) or chronic (n = 5; four women, one man; mean age 48 years) Crohn's disease were included in this institutional review board-approved, retrospective study. Magnetic resonance imaging (MRI; 1.

Software-assisted small bowel motility analysis using free-breathing MRI: feasibility study.

Purpose: To validate a software prototype allowing for small bowel motility analysis in free breathing by comparing it to manual measurements.

Materials And Methods: In all, 25 patients (15 male, 10 female; mean age 39 years) were included in this Institutional Review Board-approved, retrospective study. Magnetic resonance imaging (MRI) was performed on a 1.

Crohn's disease: small bowel motility impairment correlates with inflammatory-related markers C-reactive protein and calprotectin.

Background: To evaluate the correlation between the levels of C-reactive protein (CRP), calprotectin, and small bowel motility in patients with Crohn's disease assessed with MRI.

Methods: This prospective institutional review board approved study included magnetic resonance imaging enterography (MRE) and analyses of inflammatory markers in blood (C-reactive protein) and feces (calprotectin). For cine MRE, a coronal 2D-T2w sequence was used on a 1.

Automatic detection of small bowel contraction frequencies in motility plots using lomb-scargle periodogram and sinus-fitting method--initial experience.

Purpose: Contraction frequencies are an important parameter for the analysis of bowel motility in MRI. The contraction curve can be rather noisy and the frequency-evaluation might be difficult. The aim was to evaluate manual calculations of small bowel contraction frequency in comparison with automatic calculations using two mathematically established methods.
