Emergency MRI in Clinical Peracute Brain Stem and Hemispheric Stroke
1998
We show the capability and results of MRI examinations of peracute brainstem and hemispheric stroke patients in clinical emergency situations. The hypothesis that CT scan is faster and more accurate under this conditions is to be disproved.
Intestinal Ischemia: US-CT findings correlations.
2013
Background Intestinal ischemia is an abdominal emergency that accounts for approximately 2% of gastrointestinal illnesses. It represents a complex of diseases caused by impaired blood perfusion to the small and/or large bowel including acute arterial mesenteric ischemia (AAMI), acute venous mesenteric ischemia (AVMI), non occlusive mesenteric ischemia (NOMI), ischemia/reperfusion injury (I/R), ischemic colitis (IC). In this study different study methods (US, CT) will be correlated in the detection of mesenteric ischemia imaging findings due to various etiologies. Methods Basing on experience of our institutions, over 200 cases of mesenteric ischemia/infarction investigated with both US and …
Gastrointestinal perforation: ultrasonographic diagnosis.
2013
Abstract Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment. Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum. The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance. It is best detected using linear probes in the right upper q…

Assessment of myometrial infiltration and preoperative staging by transvaginal ultrasound in patients with endometrial carcinoma
1995
In recent years, the incidence of carcinoma of the endometrium has shown an upward trend, such that it is currently the most frequently encountered malignant tumor of the female genital tract. An accurate preoperative diagnosis of the extent and spread of such carcinomas is of crucial importance for the selection of a therapeutic approach appropriate to the stage and infiltration of each particular tumor. In a prospective study of 80 patients with a carcinoma of the endometrium, performed at the Department of Obstetrics and Gynecology of the University of Mainz, we compared the preoperative findings of transvaginal sonography with the postoperative histological results with respect to the f…
