BACKGROUND A sensitive method to detect intrathecal IgG production is important in diagnosing inflammatory central nervous system (CNS) diseases, including multiple sclerosis (MS). OBJECTIVE To compare cerebrospinal fluid (CSF) electrophoresis with isoelectric focusing (IEF), immunofixation-peroxidase electrophoresis (IFPE) and high-resolution agarose(More)
In 150 patients with possible deep venous thrombosis in the lower extremities, the diagnostic accuracy of real time ultrasonography (US) with 3.5, 5.0 or 7.5 MHz transducers was assessed using venography as standard. In the area of the common femoral/popliteal vein, US was correct in 147 patients, giving an accuracy of 98 percent. There were no false(More)
It has been assumed that the introduction of ultrasonography in diagnostic imaging has led to dramatic changes in imaging routines by replacing other modalities like angiography, intravenous urography, and computerized tomography in several diagnostic procedures. The present retrospective study from five Norwegian hospitals during the period from 1978 to(More)
In 54 patients with suspected deep vein thrombosis in the lower extremity, B-scan ultrasonography was compared with contrast venography for diagnostic accuracy. In the area of the common femoral/popliteal vein ultrasonography was correct in 53 patients, giving an accuracy of 98% (53/54). There were no false-negative studies, which gives a sensitivity of(More)
The roles of liver scintigraphy in addition to other imaging modalities of the esophagus and the small bowel and the use of abdominal flat films were studied in six Norwegian hospitals between 1975 and 1993. Parallel to the introduction of ultrasonography, the use of liver scintigraphy disappeared almost completely. Barium studies of the esophagus, to some(More)
Procedures for imaging the urinary tract have been recorded in six Norwegian hospitals for the last 24 years. For three of the hospitals, data were collected from 1965 to 1989, and for the other three from 1966, 1971 and 1975, respectively. There was a significant reduction in the number of intravenous pyelograms, voiding cystograms, and renal angiograms,(More)
The pattern of examinations at the x-ray department of Buskerud sentralsykehus has changed over the last 25 years. Heart- lung- and skeleton examinations remain unchanged, and represent 71 to 79% of the total number, but there has been a marked charge in other examinations. Through the years there has been a marked decline in the number of "classical"(More)
In a retrospective study on diagnostic imaging of the stomach and large bowel, we evaluated the examination routines in six Norwegian hospitals for the period between 1975 and 1992. For both organ systems, a shift in routines from radiological examination toward endoscopy was observed. For the stomach there was a significant correlation between an increase(More)
