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)
PURPOSE To evaluate whether the image fusion with contrast enhanced ultrasound (CEUS) and CT affects the diagnosis of endoleaks in unclear cases. METHODS AND MATERIALS 35 patients with follow-up examinations after endovascular aneurysm repair (EVAR) were included in this retrospective study. Mean patient age was 73 years (range 54-83 y). B-scan, colour(More)
OBJECTIVES Pericardial adipose tissue (PAT) is associated with coronary artery plaque accumulation and the incidence of coronary heart disease. We evaluated the possible incremental prognostic value of PAT for future cardiovascular events. METHODS 145 patients (94 males, age 60 ± 10 years) with stable coronary artery disease underwent coronary artery(More)
INTRODUCTION Lipoprotein a (Lp(a)) has been recognized as a risk factor for both coronary heart diseases and for cardiovascular events. Coronary artery calcification (CAC) is a well proven marker for coronary artery disease and risk factor for cardiovascular events. Still there are conflicting data regarding the relationship of Lp(a) and CAC. We therefore(More)
OBJECTIVE The purpose of this study is to correlate the presence of intradiscal vacuum phenomenon on CT to that of intradiscal fluid on MRI. SUBJECTS AND METHODS In a prospective study, 20 patients with lumbar vacuum phenomenon on CT underwent two MRI examinations. One was performed after mobilization, and the other was performed after 6 hours of bed(More)
PURPOSE To evaluate the feasibility of the classification of endoleaks following endovascular aortic aneurysm repair using the time-to-peak of the contrast agent in CEUS examinations. MATERIAL AND METHODS In this retrospective study, a cohort of 171 patients with a total of 489 CEUS follow-up examinations after EVAR were included. In 254 of the 489(More)
CONCLUSION The length of the cochlea can be determined with good precision using a 3D-curved multiplanar reconstruction analysis technique and linear reconstruction of the cochlea. The method is not time-consuming and can be applied during clinical routine. OBJECTIVE A preoperative prediction of the best cochlear implant electrode length can help reduce(More)
OBJECTIVES To assess the benefit of ultrasound (US) image fusion in the identifiability and assessment of the dignity of renal lesions. MATERIALS AND METHODS 25 patients with 29 renal lesions were investigated using standard US and CEUS (contrast enhanced US) with image fusion (CT or MRI). Identifiability and assessment of dignity was evaluated using(More)
OBJECTIVES To evaluate the diagnostic accuracy (DA) of CT-myocardial perfusion imaging (CT-MPI) and a combined approach with CT angiography (CTA) for the detection of haemodynamically relevant coronary stenoses in patients with both suspected and known coronary artery disease. DESIGN Prospective, non-randomised, diagnostic study. SETTING Academic(More)
PURPOSE To compare the value of high-resolution contrast-enhanced ultrasound in the detection and characterisation of endoleaks after EVAR. MATERIAL AND METHODS In this retrospective study, a cohort of 80 patients underwent both standard examination using a curved array 5 MHz transducer and a second examination using a curved array 9 MHz transducer.
