OBJECTIVES: Assessment of malnutrition-related muscle depletion with computed tomography (CT) using skeletal muscle index (SMI) and muscle radiation attenuation (MRA) at the third lumbar vertebra is well validated. However, SMI and MRA values at other vertebral locations and interchangeability as parameters …

INTRODUCTION: In patients with cancer, low muscle mass has been associated with a higher risk of fatigue, poorer treatment outcomes, and mortality. To determine body composition with computed tomography (CT), measuring the muscle quantity at the level of lumbar 3 (L3) is suggested. However, in patients …

Introduction: There is currently no standardized method for measuring wrist kinematics in a 4D CT scanner. Various methods of wrist motion during a 4D CT scan have been reported in the literature, including asking the patient to move the wrist or using a motion guidance device. No research was done into …

Low muscle mass is associated with adverse outcomes after surgery. This study examined whether facial muscles, such as the masseter muscle, could be used as a proxy for generalized low muscle mass and could be associated with deviant outcomes after carotid endarterectomy (CEA). As a part of the Vascular …

Background: Manual muscle mass assessment based on Computed Tomography (CT) scans is recognized as a good marker for malnutrition, sarcopenia, and adverse outcomes. However, manual muscle mass analysis is cumbersome and time consuming. An accurate fully automated method is needed. In this study, we evaluate …

Soms is het nodig om röntgenonderzoek te laten doen. Met een röntgenonderzoek kunnen eventuele afwijkingen in het lichaam worden gevonden. Bijvoorbeeld met een röntgenfoto van je gebit bij de tandarts. Of een CT-scan van je buik om te kijken of hier een afwijking zit. Maar, is dit ook veilig wanneer …

Rationale: Patients with cancer of the upper gastrointestinal tract or lung are more likely to present with malnutrition at diagnosis than, for instance, patients with melanoma. Low muscle mass is an indicator of malnutrition and can be determined by computed tomography (CT) analysis of the skeletal …

A hospital visit is often an anxious and uncertain event for patients and their relatives. Patients are often concerned about a diagnosis and/or the treatment of their disease in an outpatient or inpatient setting. In these hospital settings, the impact of the environment on patients is still not well …

Cone beam CT scanners use much less radiation than to normal CT scans. However, compared to normal CT scans the images are noisy, showing several artifacts. The UNet Convolutional Neural Network may provide a way to reconstruct the a CT image from cone beam scans.

Background & aims: Optimal nutritional support during the acute phase of critical illness remains controversial. We hypothesized that patients with low skeletal muscle area and -density may specifically benefit from early high protein intake. Aim of the present study was to determine the association …
