UNLABELLED Accurate γ-photon attenuation correction (AC) is essential for quantitative PET/MRI as there is no simple relation between MR image intensity and attenuation coefficients. Attenuation maps (μ-maps) can be derived by segmenting MR images and assigning attenuation coefficients to the compartments. Ultrashort-echo-time (UTE) sequences have been used(More)
Most patients with a history of common solid tumors will in the end develop liver metastases. Next to that, primary liver cancer, is a frequent cancer with fatal liver failure in the majority of patients. Selective internal radiation therapy (SIRT), has gradually been introduced over the recent years and is a promising, innovative albeit palliative(More)
Transthoracic echocardiography is usually the initial diagnostic test in patients with a suspected cardiac mass. However, this technique is restricted by its small field of views and insufficient acoustic window in some patients. Magnetic resonance imaging (MRI) and, since its introduction, multislice spiral computed tomography allow for detailed(More)
To evaluate the influence of intravenous contrast medium and different contrast medium phases on attenuation correction, PET image quality and clinical staging in combined PET/CT in patients with a suspicion of lung cancer. Sixty patients with a suspicion of lung cancer were prospectively enrolled for combined 18F-FDG-PET/CT examination. PET images were(More)
Ein 56-jähriger Patient stellte sich mit rezidivierenden Palpitationen bei seinem Hausarzt vor. Ursächlich für die Palpitationen war paroxysmales Vorhofflimmern. In einer kardialen Computertomografie zeigte sich kein Hinweis auf koronare Verkalkungen, jedoch nebenbefundlich ein Rundherd im linken Lungenunterlappen. Zur weiteren Abklärung des(More)
Die eosinophile Ösophagitis (EÖ), ein primär internistisches Krankheitsbild, sollte dem Chirurgen und Endoskopiker als Differenzialdiagnose der Dysphagie geläufig sein. Wir präsentieren einen chronischen Fall einer EÖ. Wie so häufig, zeigen sich makroskopische Hinweise auf die ursächliche Erkrankung. Die Diagnose wird letztendlich durch den histologischen(More)
