BACKGROUND: Muscle quantity at intensive care unit (ICU) admission has been independently associated with mortality. In addition to quantity, muscle quality may be important for survival. Muscle quality is influenced by fatty infiltration or myosteatosis, which can be assessed on computed tomography …

BACKGROUND: In critically ill patients, muscle loss is associated with adverse outcomes. Raw bioelectrical impedance analysis (BIA) parameters (eg, phase angle [PA] and impedance ratio [IR]) have received attention as potential markers of muscularity, nutrition status, and clinical outcomes. Our objective …

Abstract: Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. …

In this thesis, we present an articulated, empirical view on what human music making is, and on how this fundamentally relates to computation. The experimental evidence which we obtained seems to indicate that this view can be used as a tool, to systematically generate models, hypotheses and new technologies …

In this thesis the research on the automatic constructing of intelligible digitally reconstructed radiographs (DRR’s) of the hips is described. This project was initialized when the Department of Orthopedic surgery, within UMC Utrecht, decided to research the relation between spinopelvic parameters and …

Op verzoek van Jelle Scheurleer: Purpose: To investigate the accuracy of dose calculation on cone beam CT (CBCT) data sets after HU-RED calibration and validation in phantom studies and clinical patients. Material and methods: Calibration of HU-RED curves for kV-CBCT were generated for three clinical …

Incidental findings on low-dose CT images obtained during hybrid imaging are an increasing phenomenon as CT technology advances. Understanding the diagnostic value of incidental findings along with the technical limitations is important when reporting image results and recommending follow-up, which may …

In Nederland is volgens de Nederlandse Kankerregistratie een stijging van het aantal patiënten met een rectumcarcinoom zichtbaar. Preoperatieve radiotherapie wordt toegepast bij intermediair risico rectumcarcinomen. Het doelgebied bestaat uit het Gross Target Volume, het Clinical Target Volume (CTV) …

Achtergrond: Het doel van dit onderzoek is om te bepalen of een RapidArc plan op een diagnostische CT voor patiënten met wervelmetastasen een kwalitatief vergelijkbaar bestralingsplan laat zien in vergelijking met hetzelfde RapidArc plan gekopieerd en niet geoptimaliseerd op de plannings-CT. Het verschil …

Een nadeel van bestraling van de parasternale klieren is het niet zichtbaar worden op de Computed Tomography, waardoor de parasternale klieren worden ingetekend met behulp van de European SocieTy for Radiotherapy & Oncology (ESTRO). Door de Single Photon Emission Tomography - Computed Tomography (SPECT-CT) …
