Tidskriftsartikel (refereegranskat)abstract
- The pharyngoesophageal segment (PES) is a striated muscular structure separating the relatively wide pharynx from the narrow cervical esophagus. There is a substantial axial and longitudinal asymmetry within the PES, as well as basal resting pressure that is substantially influenced by a variety of stimuli as well as deglutition.

Strahlendosis bei renaler Vergrosserungsangiographie im Vergleich mit konventioneller Angiographie

- Measurements of skin dose, integrated skin dose area, and integral dose in combined conventional and magnification renal angiography using lanthanoxibromide screens MR 600 and carbon fibre plate in filmchangertop have been made. The mean skin dose in magnification technique was 0.56 rad./film with focus-skin distance of 35 cm, FFD 1 m, 85-90 kV and sagittal diameter of abdomen of 20 cm. The combination of angiographic technique with and without magnification and the use of a high-sensitivity receiving unit makes it possible to keep the total skin dose per investigation (8.5 rad.) within the limits accepted in conventional abdominal angiography.

Simultane Videoradiographie und "solid state" intraluminale pharyngeale Manometrie wahrend des Bariumschluckakts; Videomanometrie
- 1995
-
Ingår i: Radiologe. - 0033-832X. ; 35:10, s. 753-758
-
Tidskriftsartikel (refereegranskat)abstract
- Recent advances in technology, including computerized analysis, have renewed interest in pharyngeal manometry. Simultaneous fluoroscopy and videography have been recommended by many authors. This article reviews the history of pharyngeal manometry and highlights some of the technical difficulties involved. We also report the current status of the simultaneous technique and summarize our own results as well as those reported by other research groups.

Acute, non traumatic patterns in chest radiography of children - recognition and understanding of radiographic appearances
- 2002
-
Ingår i: Radiologe. - : Springer Science and Business Media LLC. - 0033-832X. ; 42:3, s. 153-161

Tidskriftsartikel (refereegranskat)abstract
- The diagnosis of acute, non-traumatic diseases of the lower respiratory tract requires exact knowledge of the specific anatomy, physiology and pathology of the pediatric chest. The absolutely and relatively smaller airways, as compared with those of adults, and the undeveloped collateral ventilation result in radiological appearances that are unique in children. Viral pneumonia is predominant only in small children up to an age of 2 years. With increasing age, there is a higher incidence of bacterial pneumonia. The differentiation of viral and bacteria[ etiology of a pneumonia is not possible on the basis of chest radiographs. In acute pediatric imaging, possible aspiration of foreign bodies has to be considered. Since most foreign bodies cannot be detected radiographically, indirect features such as hyperinflation or mediastinal shifts have to be evaluated. Primary lung tumors are rare in children. More common are metastases with known primary tumors. Neuroblastoma or I ymphomas may mimic intrapulmonary pathologies.
