Two families are described which appear to contain examples of multiple epiphyseal dysplasia. In both families a striking incidence of severe osteochondritis of the knees was encountered. It is suggested that this was caused by the fragmented and maldeveloped epiphyses characteristic of epiphyseal dysplasia.
AIMS With the increasing use of screening mammography, more and more non-palpable lesions are found. As less invasive techniques like core needle biopsy are introduced, we evaluated our experience with the well-known standard procedure of surgical excision after wire localization. METHODS We retrospectively evaluated the results of 479 wire localizations(More)
Real-time ultrasonography (US) was used as a single non-invasive method in the management of 174 patients (56 inpatients and 118 outpatients) with suspected deep-vein thrombosis (DVT). Therapeutic decisions were based on the results of ultrasonography alone. If the US examination was abnormal anticoagulant treatment was started. If the initial US(More)
Left renal vein compression occurring mainly with the patient in the upright position, and being less severe or absent in the supine position, was considered to be the main cause of varicoceles. We show that left renal vein compression is, indeed, more severe with the patient in the upright than in the supine position and that it produces a left renocaval(More)
We studied the frequency of restenosis and the effects of percutaneous transluminal renal angioplasty (PTRA) on blood pressure (BP) and particularly on renal function in all patients in whom successful dilatation was performed. Restenosis was found in 42% of the patients with an atherosclerotic renal artery stenosis and in 22% of the patients with(More)
INTRODUCTION The objective of this study is to compare different methods for measuring breast density, both visual assessments and automated volumetric density, in a breast cancer screening setting. These measures could potentially be implemented in future screening programmes, in the context of personalised screening or screening evaluation. MATERIALS(More)
To determine whether the varicocele results from collateral circulation partially replacing an obstructed left renal vein, we developed a scintigraphic technique that provides not only information about the velocity of retrograde flow in the testicular veins but also quantitative information about the size of the varicocele. The reliability of this method(More)
OBJECTIVES To determine the influence of local contrast optimisation on diagnostic accuracy and perceived suspiciousness of digital screening mammograms. METHODS Data were collected from a screening region in the Netherlands and consisted of 263 digital screening cases (153 recalled,110 normal). Each case was available twice, once processed with a tissue(More)
OBJECTIVE To estimate the potential of low-dose images in digital mammography by analysing the effect of substantial dose reduction in craniocaudal (CC) views on clinical performance. METHODS At routine mammography, additional CC views were obtained with about 10% of the standard dose. Five radiologists retrospectively read the standard [mediolateral(More)
