Automatic segmentation of the liver and its lesion is an important step towards deriving quantitative biomarkers for accurate clinical diagnosis and computer-aided decision support systems. This paper presents a method to automatically segment liver and lesions in CT abdomen images using cascaded fully convolutional neural networks (CFCNs) and dense 3D(More)
BACKGROUND AND PURPOSE Vertebral artery hypoplasia (VAH) is supposed to be a risk factor for posterior circulation ischemia (PCI), particularly in the territory of the posterior inferior cerebellar artery (PICA). The aim of our study was to determine whether VAH impedes perfusion in the dependent PICA territory even in the absence of manifest PCI. METHODS(More)
OBJECTIVES To define predictive parameters of long progression-free survival (PFS) in patients undergoing radioembolisation of neuroendocrine liver metastases. METHODS The following clinical and magnetic resonance imaging (MRI) parameters of 45 radioembolised patients (median age, 62 years; range, 43-75) were reviewed: age, gender, levels of chromogranin(More)
PURPOSE The aims of this study were to determine the diagnostic accuracy of whole-brain computed tomographic perfusion (WB-CTP) in small ischemic brain infarctions and to identify factors influencing the detection rate. MATERIALS AND METHODS Out of a retrospective cohort of 1380 subjects who underwent initial WB-CTP because of suspected stroke, we(More)
Restoration of sinus rhythm may result in an improvement of left heart function in patients with atrial fibrillation (AF). Cardiovascular magnetic resonance (CMR) feature tracking (FT) technique may help detect subtle wall-motion abnormalities. Consequently this study aimed to analyse existence and reversibility of subclinical cardiac dysfunction following(More)
PURPOSE To evaluate changes in aortoiliac volume after endovascular repair (EVAR) for abdominal aortic aneurysm (AAA) in patients with and without endoleaks. MATERIALS AND METHODS We retrospectively analyzed 137 patients who underwent EVAR for AAA. We manually measured the aortoiliac volume on pre-procedural baseline CT angiograms (CTAs) and(More)
To evaluate the effect of structured reports (SRs) in comparison to non-structured narrative free text (NRs) shoulder MRI reports and potential effects of both types of reporting on completeness, readability, linguistic quality and referring surgeons’ satisfaction. Thirty patients after trauma or with suspected degenerative changes of the shoulder were(More)
PURPOSE To evaluate the diagnostic accuracy of dynamic-contrast-enhanced (DCE) MRI in comparison to both (18)F-FDG- and (68)Ga-DOTATATE-PET/CT in patients with liver metastases of neuroendocrine neoplasms (NEN). MATERIALS AND METHODS Thirty-two patients with hepatic metastases from NEN were examined both in DCE-MRI and positron emission(More)
Endovascular aortic repair (EVAR) has become established in the treatment of abdominal aortic aneurysms and shows potential benefits such as a low perioperative morbidity and a short hospitalization duration. The follow-up after EVAR primarily consists of lifelong postinterventional imaging of the aneurysm size in order to detect complications such as(More)
