Abstract null null Purpose null Total Skin Electron Irradiation (TSEI) is a method for treating malignant cutaneous T-cell lymphomas. This work aims to implement and optimize the total skin technique established at Strahlenklinik Erlangen, Germany on two new linear accelerators and to quantify the risks using failure mode and effects (FMEA) analysis. null null null Material and methods null TSEI is performed at a VersaHD accelerator (Elekta, Stockholm) with 6 MeV in the “high dose rate mode” HDR...

Abstract null null Purpose null To measure multi-quantum coherence (MQC) 23Na signals for noninvasive cell physiological information in the whole-brain, the 2D-CRISTINA method was extended to 3D. This experimental study investigated the use and results of a new sequence, 3D-CRISTINA, on a phantom and healthy volunteers. null null null Methods null The 3D Cartesian single and triple-quantum imaging of 23Na (3D-CRISTINA) was developed and implemented at 7T, favoring a non-selective volume excitati...

Abstract Background and objective Purpose of this investigation was to get deeper insight into the impact of different radiation techniques and doses on cardiac implantable electric devices (CIEDs). We aimed to mimic a worst-case scenario with very high doses and external radiation being applied directly on the devices. Methods Radiation was applied on 21 CIEDs as photon or electron therapy with maximum dose of 150 Gy in fractions of 2 -20 Gy. CIEDS were put directly into the beam. Brachytherapy...

Abstract The various methods of medical imaging are essential for many diagnostic issues in clinical routine, e.g., for the diagnostics and localisation of tumorous diseases, or for the clarification of other lesions in the central nervous system. In addition to these classical roles both positron emission tomography (PET) and magnetic resonance imaging (MRI) allow for the investigation of functional processes in the human brain, when used in a specific way. The last 25 years have seen great pro...

Zusammenfassung Anlasslich des 200. Geburtstags von Hermann von Helmholtz gibt der Artikel einen Ruckblick uber die Entwicklung der Audiologie in den letzten zwei Jahrhunderten. Die moderne Audiologie versteht sich als multidisziplinares Fachgebiet, das sich mit der Erforschung der Ursachen von Horstorungen und aller damit zusammenhangenden Phanomene, insbesondere Pravention/Protektion, Diagnostik und Behandlung von Horstorungen sowie der Rehabilitation schwerhoriger und gehorloser Menschen befa...

Abstract Introduction Despite using the soft-surgery technique, cochlear implantation may increase the damage of the intracochlear structures due to a scalar translocation of the electrode. The aim of this work was to investigate the incidence as well as the audiological and electrophysiological outcome for electrode translocations and complete scala tympani insertions of perimodiolar electrodes within a large group of patients. Material and methods The investigations were performed retrospectiv...

Zusammenfassung Hintergrund In seltenen Fallen kann es bei einer Cochlea-Implantation wahrend der Elektrodentragerinsertion zu einem sogenannten Tip-Foldover kommen. Um eine solche Fehllage zu erkennen oder sicher auszuschliesen, wird intra- oder oftmals erst postoperativ eine radiologische Kontrolle des Cochlea-Implantat(CI)-Elektrodentragers durchgefuhrt (Goldstandard). Der Patient ist dabei einer zusatzlichen Strahlenbelastung ausgesetzt. Alternativ kann die Lagekontrolle auch mit einer Messu...

Introduction: Quantitative Susceptibility Mapping (QSM) is generally acquired with full brain coverage, even though many QSM brain-iron studies focus on the deep grey matter (DGM) region only. Reducing the spatial coverage to the DGM vicinity can substantially shorten the scan time or enhance the spatial resolution without increasing scan time; however, this may lead to significant DGM susceptibility underestimation. Method: A recently proposed deep learning-based QSM method, namely xQSM, is inv...
