AIM To evaluate in a multicenter study whether the sonographic characterization of focal liver lesions can be improved using SonoVue-enhancement; and to compare this method with computed tomography (CT) and magnetic resonance imaging (MRI). METHODS One hundred and thirty four patients with one focal liver lesion detected in baseline ultrasound (US) were(More)
Of the noncollagenous proteins in bone, about 20% consists of osteocalcin. This vitamin K-dependent protein can be found in adult bone, but its presence in embryonic bone could not be demonstrated unequivocally by biochemical methods. Therefore, we used light and electron microscopic immunohistochemical methods to investigate whether osteocalcin(More)
Purpose: To report our experience and results with the endovascular treatment of central vein stenoses and occlusions in hemodialysis patients. Methods: Between October 1999 and August 2001 (22 months) we performed 22 interventional procedures in 14 hemodialysis patients (8 women, 6 men) ranging in age from 38 to 87 years (mean 76 years). The indication for(More)
Background. Several mathematical models have been developed for predicting individual breast cancer risk. Such models can help clinicians to choose appropriate preventive and therapeutic interventions for each patient. Unfortunately, the validity of these models has not been tested outside the USA.   Methods. The authors describe a case–control study in the(More)
Regular expansion of heterogeneous populations of epithelial cells, including the luminal phenotype, was achieved from small biopsies of human breast tumours and cutaneous metastases by optimized feeder layer technique based on irradiated NIH 3T3 cells. Forty-one out of 47 primary tumour specimens and all three cutaneous metastases grew successfully for two(More)
We aimed to evaluate the differential diagnostic value of a method of computer-assisted texture analysis in comparison to established ultrasonographic B-mode characteristics in the examination of solid breast masses. At two centers, 77 patients presenting with a solid mass on B-mode scan were studied at 7.5 MHz. Description of B-mode appearance included(More)
This paper demonstrates the statistical processing of data from a multicentric study. Seventy-seven patients with a suspicious, solid breast mass were included in a two-center study, using clinical breast examination, mammography, and ultrasound. The assessment was formalized using a uniform evaluation sheet. The prospective results of the examinations were(More)
EUSOBI and 30 national breast radiology bodies support mammography for population-based screening, demonstrated to reduce breast cancer (BC) mortality and treatment impact. According to the International Agency for Research on Cancer, the reduction in mortality is 40 % for women aged 50–69 years taking up the invitation while the probability of(More)
The presence of myocardial fibrosis is associated with adverse outcome in dilated cardiomyopathy (DCM). Delayed contrast-enhanced cardiac magnetic resonance (DE-CMR) currently represents the gold standard in noninvasive evaluation of myocardial scarring. However, a significant number of patients are unable to undergo DE-CMR study for various reasons. We(More)
BACKGROUND Computed tomography (CT) colonography is a well established modality for the examination of symptomatic patients as well as in screening. Recent technical advances in improving image quality by iterative reconstruction contribute to the reduction of the radiation dose which is a major concern in CT imaging. PURPOSE To evaluate image quality of(More)
