Malignant hepatic epithelioid hemangioendothelioma (HEH) is a rare malignant tumor of vascular origin with unknown etiology and a variable natural course. The authors present a comprehensive review of the literature on HEH with a focus on clinical outcome after different therapeutic strategies. All published series on patients with HEH (n = 434 patients)(More)
OBJECTIVE To evaluate the accuracy of multidetector computed tomography (CT) and magnetic resonance imaging (MRI) in staging and estimating renal carcinomas with caval thrombus. METHODS Initially, 23 patients with suspected caval thrombi were admitted into this prospective study. Triphasic CT imaging was performed using a multidetector CT with a(More)
PURPOSE We prospectively evaluated long-term survival in patients with renal cell carcinoma extending to the inferior vena cava. MATERIALS AND METHODS From 1993 and thereafter we followed 86 men and 48 women with a median age of 64 years (range 28 to 86) with renal cell carcinoma and tumor thrombus involvement of the inferior vena cava. Cancer specific(More)
The goal of this article is to provide an overview of diagnostic standard operating procedures for both clinical and imaging assessment of cervical and endometrial carcinoma, sarcoma of the uterus, and primary pelvic non-Hodgkin’s lymphoma. The literature was reviewed for methods used to diagnose malignancies in the female pelvis with a special focus on the(More)
OBJECTIVE The purpose of this study was to evaluate retrospectively the diagnostic value of MRI in the care of patients with suspected scrotal disorders. MATERIALS AND METHODS Testicle-containing scrotal compartments were evaluated by examiners blinded to all clinical information in an interdisciplinary consensus reading after MRI was performed with(More)
OBJECTIVES Several histologic studies showed more favorable oncologic outcome for renal cell carcinoma (RCC) with cystic change. However, there is no prognostic tool to judge on cystic RCC preoperatively. We hypothesized, that cystic morphology in cross-sectional imaging predicts lower malignant potential. MATERIALS AND METHODS From our prospectively(More)
OBJECTIVE The objective of this study was to compare clinical chest radiographs of a large-area, flat-panel digital radiography system and a conventional film-screen radiography system. The comparison was based on an observer preference study of image quality and visibility of anatomic structures. MATERIALS AND METHODS Routine follow-up chest radiographs(More)
AIMS To investigate the characteristics of metastasis to the pancreas using computed tomography (CT) and magnetic resonance imaging (MRI). METHODS Twenty-two patients with metastases to the pancreas were examined preoperatively by MRI (7/22) and/or multidetector CT (15/22). Pre- and post-contrast images were acquired and morphology, size, and contrast(More)
Early HAT is the most frequent and severe vascular complication following liver transplantation. It is one of the major causes of graft failure and mortality. Endovascular thrombolytic treatment in patients with thrombotic complications after liver transplantation is an attractive alternative to open surgery as lower morbidity and mortality rates are(More)
OBJECTIVES To assess the pharmacodynamic behavior of cyanoacrylate, streptavidin-coated microbubbles (MBs) and to investigate their suitability for molecular ultrasound imaging. MATERIALS AND METHODS Biodistribution of MBs was analyzed in tumor-bearing mice using gamma-counting, immunohistochemistry, flow cytometry, and ultrasound. Further, vascular(More)
