Normalwerterstellung von Blutströmungsgeschwindigkeiten an der Arteria mesenterica superior bei Früh- und Reifgeborenen mit der Duplexsonographie

1994

In a prospective study blood flow velocity measurements were performed in 110 "healthy" newborn with duplex Doppler sonography in the superior mesenteric artery to obtain standard values. In 49 of these neonates 15, 30, and 45 minutes following feeding examinations were performed. Peak systolic flow velocity, end systolic flow velocity, time average flow velocity and time average maximum flow velocity were determined, the resistance and Pourcelot index as well as the volume blood flow were calculated. The children's gestational age was 27-42 weeks, the postnatal age was 2-68 days and the body weight was 920-4190 g. All measured blood flow velocities showed a synchronous relation to feeding …

Rechte und Pflichten des Radiologen bei der Indikationsstellung und Anwendung radiologischer Verfahren

2008

A radiological examination or an interventional procedure is a medical invasion of the patient's freedom and does not constitute an offense of causing bodily harm there is a medical indication, when the patient has given consent after being adequately informed, and the intervention is carried out in accord with the valid rules of medical conduct. During the assessment of possible contraindications, the radiologist must also evaluate the indicationy, i.e., he or she must decide if the medical question can be answered by the requested radiological examination. The indication must be viewed the more critically the greater the risk for a complication is. A radiological diagnosis with the use of…

MR-Tomographie bei Innenbandverletzungen des Kniegelenkes

1992

Frequency and characteristics of lesions of the medial collateral ligaments (MCL) were studied by MRI in 155 patients with trauma to the knee. There were abnormalities of the MCL in 38% of cases with ligamentous injuries and in 27% these were combined with meniscal tears. 11% of these patients showed isolated rupture of MCL and as a result of the MRI findings were treated conservatively. By means of T2*-weighted images the individual lesions could be accurately localised. Characteristic findings have been defined.

Messung der Pfannenwanderung bei zementfreien Hüftimplantaten

1998

PURPOSE Migration measurements of acetabular components using a special computer aided method (EBRA = abbreviation for the German term "Ein-Bild-Rontgenanalyse") were performed to evaluate early results of the implants and predict aseptic loosening. METHODS Standard ap-radiographs of the pelvis were marked, specific points were digitised. Simulating the spatial situation the programme computes longitudinal and vertical migration of the cup. 74 acetabular components in 71 patients could be studied by migration measurements. RESULTS 14 patients showed migration of more than 1 mm, which is the confidence limit of this method. Each of these patients showed diverse reasons for the migration, i.e…

Skelettveränderungen bei Frühgeborenen mit Kupfermangel

1991

We describe 5 preterm infants (25th to 30th week of gestation) suffering from alimentary copper deficiency. The diagnosis was confirmed by low serum copper and caeruloplasmin concentrations. Characteristic clinical findings were repeated apnoeic attacks, hypopigmentation of skin and hair, anaemia, neutropenia and leucopenia refractory to other therapy, as well as increasing serum alkaline phosphatase activity in the first month of life. Starting in the 3rd to 12th week of life the radiographic findings were general skeletal osteoporosis and retardation, metaphyseal radiodense lines, irregular metaphyses, cupping and spurring of the metaphyses, followed by multiple fractures and subperiostea…

Bildgebende Diagnostik der Peritonealkarzinose

1990

Two hundred and eighty-seven radiological and sonographic examinations in 142 patients with confirmed peritoneal carcinosis were evaluated retrospectively. The examinations included abdominal films (19), infusion urograms (20), contrast examinations of the intestine (26), small bowel enemas (2), double-contrast examinations of the colon (40), demonstrations with water-soluble contrast (6), sonographies (80) and CTs (96). CT and colonic double-contrast studies were complementary and valuable methods for diagnosing peritoneal carcinosis and should both be used.

Der Sicherheitsgurt: Auswirkungen auf das Verletzungsmuster von Autoinsassen

1993

Since 1984 the law concerning safety belts has been implemented; this paper deals with the findings in 386 victims of motor accidents who were x-rayed between 1981 and 1989. Minor injuries have been ignored. The number of passengers wearing belts increased by 30% after 1984. The number of passenger injuries did not decrease. Injuries directly caused by the belts included a small number of fractures of clavicles, the sternum and ribs and one pelvic fracture, one serious abdominal injury with tearing of the mesenteric artery and one ruptured spleen. An indirect result of wearing seat belts was a marked increase in cervical whiplash injuries and some increase in thoracic vertebral fractures. N…
