Evaluation eines hepatischen Perfusionsindex zur Früherkennung von Tumorrezidiven nach RFA und Erkennung von Leber-Malignomen bei Leberzirrhose
… multislice computed tomography (MSCT) images. Follow-up examinations served as standard of reference. The diagnostic performance of the AEF color maps to predict subsequent tumor occurrence before it was visible on routine multiphase CT images was evaluated with receiver-operating …

Funktionsdiagnostik des Herzens mittels Dual-Source-Computertomographie im Vergleich zur Magnetresonanztomographie : eine tierexperimentelle Studie an Schweinen
… multi-slice spiral computed tomography (MSCT) and MRI while determining the cardiac volumetry. Good to excellent analogies were discovered. The distinctiveness of dual-source computed tomography (DSCT) is to be found in its two tube detector systems, thus contrasting conventional MSCT. …

Exploring model parallelism in distributed scheduling of neural network frameworks
… Networks. We propose, analyze and evaluate mSCT, a polynomial time algorithmic solution to this end. Additionally, we formulate an exponential time optimal ILP solution that models the placement problem. We summarize our contributions as: 1. We propose a theoretical solution to the memory …

Diagnostik der Lungenembolie mit der Mehrzeilenspiralcomputertomographie
… Einschränkungen für die Aussagekraft der MSCT in der Lungenemboliediagnostik auf der Subsegmentarterienebene zu widerlegen. Die Patienten wurden mit 1 mm dicken Schichten untersucht, die Bilddaten wurden mit 1 mm-, 2 mm- und 3 mm-Schichtdicke rekonstruiert und die resultierenden Bilder von …

Hyperpolarized 3He-diffusion MRI in evaluation of lung structure in emphysema. Validation and development of the method
… hyperpolarized 3He-diffusion MRI technique with MSCT and different PFT:s. The mean ADC correlated well with emphysema index and 15th percentile from CT. DL,CO is the PFT best correlating with emphysema grade and the correlation was higher between 3He -MRI and DL,CO than between CT and DL,CO. …

Development of a patient-specific finite element model of the transcatheter aortic valve implantation (TAVI) procedure
… the provided Multi-Slice Computer Tomography (MSCT) images of the patients. An anisotropic hyperelastic material model was implemented for the roots and leaflets, using two and one families of collagen fibres for their tissues respectively. The stent is made of a cobalt-chromium alloy and its …

Bedeutung des Volume Rendering in der Diagnostik der Koronargefäße mittels Mehrschichtspiral-CT
… patients (42m, 11f), retrospectively ECG-gated MSCT of the heart was performed as well as quantitative X-ray coronary angiography. The standardized examination protocol included a collimation of 4x1mm,a tube voltage of 120kV with an effective tube current of 400 mAs and a tube rotation time of …

Experimentelle Untersuchung zum Einfluss der Dosisreduktion auf die CT-Bildqualität : Rundherddiagnostik bei Schweinelungen
Bei der Diagnostik pulmonaler Erkrankungen spielt die Computertomographie, insbe-sondere seit Einführung der Mehrschicht-CT, eine herausragende Rolle. Dabei er-weist sich jedoch nach wie vor die Strahlenexposition als limitierender Faktor. Dies ist vor allem bei Kindern und Jugendlichen zu …
