The differentiation between benign and malignant Focal Liver Lesions (FLL) plays an important role in diagnosis and therapeutic planning of liver diseases. This differentiation, based on characterization, relies on the observation of the Dynamic Vascular Patterns (DVP) of FLL with respect to surrounding healthy parenchyma, and may be observed during(More)
Turf battles have always existed in radiology although recently, we have observed an increase in their numbers and sometimes in their virulence. The main reasons for this increase include the relative plethora of physicians especially in industrialized areas, and the rapid progress and development of medical technology and minimally invasive techniques.(More)
Ultrasonography is widely accepted as the initial screening modality for patients admitted for acute abdominal pain or trauma. However, only few reports deal with the impact of sonography in the assessment of pneumoperitoneum. We report a sery of 12 patients admitted with an acute abdomen between 1990 and 1991, in whom pneumoperitoneum was first detected by(More)
The differential diagnosis of focal liver lesions (FLL) frequently presents a dilemma, as FLL cannot be reliably characterized with conventional ultrasound. Recently, ultrasound contrast agents (UCA) and contrast-specific imaging methods have substantially improved the characterization of FLL. This was made possible by the known differences in dynamic(More)
The purpose of this retrospective study was to report 11 cases of severe vascular complications after central venous catheter misplacement. For each patient, data collection included body mass index, the diagnosis at admission, the site of the procedure, the type of catheter, coagulation parameters, the imaging modalities performed and the applied(More)
The diagnostic performance of magnetic resonance imaging (MRI) for detection of intestinal fistulas, other than perianal, in patients with known complicated inflammatory bowel conditions (CIBC) was investigated. Our study group consisted of 20 patients (12 women, mean age 43 years) with CIBC, including Crohn’s disease (n=13), colonic diverticulitis (n=3),(More)
