Gösta Forssell wrote in his first editorial in 1921 that ‘‘by joint work and joint economic responsibility the journal has the support of all the radiologists of the North’’. This has been true for the last seven decades and during this time Acta Radiologica has been one of the world’s leading radiologic journals. Gösta Forssell died in 1950 and his place as editor was taken for a short period by Elis Berven. He was followed by Erik Lindgren, under whose eminent guidance (1951 to 1983) Acta Radiologica maintained its leading position. For the last decade, Erik Boijsen (1983 1992) has been chief editor of Acta Radiologica and throughout this period he has succeeded in preserving the strengths and traditions of the journal. When Erik Boijsen became chief editor of Acta Radiologica in 1983, he had been well prepared for the role by his leadership of the Lund School of Radiology. In Lund, he had been involved in research in, e.g., angiography and cardiology. Later, as chairman of the radiologic institutions in Malmö and Lund, he had helped to make both centers pre-eminent in Nordic radiology, as evidenced by the numerous foreign scientists who trained there during this time. His interest in the analysis of modern radiologic techniques, both for the county health authorities and for the central government, has since been reflected in the content of Acta Radiologica. One of the greatest achievements of Erik Boijsen, as chief editor of Acta Radiologica, was the separation of the Foundation of Acta Radiologica and Acta Oncologica in 1987. Since its inception in 1921, Acta Radiologica had covered the whole field of diagnostic radiology, radiation therapy and radiophysics, but in 1963 Acta Radiologica Diagnosis and Acta Radiologica Oncology were separated into two parallel journals. Rapid developments in both radiology and oncology necessitated similar changes and division of the Foundation of Acta Radiologica became inevitable. A happy divorce was accomplished in 1986 under the pragmatic leadership of Erik Boijsen and Lars-Gunnar Larsson and this has been of benefit to both Acta Radiologica and Acta Oncologica. At that time the subtitle ‘‘Diagnosis’’ was dropped from the journal’s title as, in the words of Erik Boijsen, it ‘‘will be reporting on research in diagnosis and interventional radiology based on all forms of imaging techniques’’. This is in accordance with the statement by Erik Lindgren in 1980 that ‘‘new methods introduced, such as ultrasound, scintigraphy, computed tomography and possibly still others such as magnetic resonance will appear (in Acta Radiologica) in the future. Acta Radiologica holds most emphatically that all imaging techniques should be concentrated in the radiology departments where the basic skills are centered’’.

Die praktische Arbeit konnte erst im November begonnen werden. Die Experimente beabsichtigten, zunächst die Koronargefässe, besonders die Arterien, röntgenologisch darzustellen.

Ich habe darum die Möglichkeiten mit Versuchen an Tieren in vivo in Betracht gezogen: einerseits direkte Punktion des Bulbus aortae, andererseits Sondierung desselben von einer peripheren Arterie aus, nach Inzision derselben sowie durch Punktion mit Spezialtroikart. Wir haben den Bulbus aortae im allgemeinen von der Arteria carotis communis dextra aus mit einem Ureterkatheter sondiert, so dass sich die Spitze unmittelbar oberhalb der Aortenklappen befindet. Beim Kaninchen z. B. ist die Sondierung leicht auszuführen. Nimmt man eine stumpfe zylindrische Sonde von geeignetem Kaliber, so passiert sie durch das Aortenostium in die linke Herzkammer hinein, ohne die Aortenklappen zu beschädigen. Da bei den Experimenten die physiologischen Verhältnisse möglichst gewahrt bleiben sollten, war nämlich das Arretieren der Sondenspitze in einer Klappentasche zu vermeiden. Die richtige Lage der Sondenspitze unmittelbar oberhalb der Aortenklappen wird mittelst Messung vom Jugulum aus, Beobachtung von Pulsation und Fremissement der Sonde, eventuell Durchleuchtung und Probeexponierung erzielt.

His figure as a leader, his innate living strength and his indefatigable energy were, no doubt, inheritances from the generations of Dalecarlian and Helsingland farmers, warriors and clergy authoritative and resolute forefathers from which he could trace his descent right back from the sixteenth century. FORSSELL’S richly facetted personality, his burning bent on research and marked scientific powers, his constructive imagination as well as his organizing capabilities were probably those qualities which caused him, whilst still in his years of study, to throw himself into an entirely new branch of medicine radiology which the discoveries of roentgen and radium rays had created. His powers of bold intuition enabled him to realize the enormous developmental possibilities of this science and its future importance for medicine. As a young medical student he served his apprenticeship under the first roentgen pioneer in Sweden, THOR STENBECK. About this time (1899) he took part in the first curative treatment in the world of a case of cancer of the skin. One hundred and fifty treatments extending over some nine months were required in all for the cure. The patient was demonstrated nearly 30 years later free from symptoms at the second International Congress of Radiology in Stockholm. One may perhaps best appreciate the progress of development when I state that a similar case in these days would be cleared up by a single treatment lasting but a minute. The outlines of FORSSELL’S radiological activities are as follows.Assistant in theRoentgenDepartment of the University Hospital of Upsala, 1902 Head of the Roentgen Institute of the Serafimerlasarettet 1906 1941.

For this purpose, we investigated different types of sequences, including gadolinium contrast medium-enhanced T1-WI images (CME T1-WI), and developed a precise method to measure tendon volume and mean intratendinous signal of the Achilles tendon. Study I aimed at evaluating 15 patients with chronic, painful Achilles tendinosis, before and 2 years after surgical treatment. There was marked regression of the intratendinous signal postoperatively. The most sensitive sequence for depicting an intratendinous lesion in this study was CME T1-WI images. They showed a regression of the intratendinous signal abnormality from 13/15 patients preoperatively to 4/15 postoperatively. The clinical outcome was excellent in eight, good in five, fair in one and poor in one patient. In study II, the early contrast agent enhancement in the dynamically enhanced MRI signal (DEMRI) was correlated with the histopathologic findings in 15 patients with chronic Achilles tendinopathy. Early contrast enhancement (within the first 72s) was seen in DEMRI in the symptomatic Achilles tendons, with a significant difference compared to the asymptomatic contralateral tendons. Increased severity of tendon changes, including fiber structure abnormality, increased vascularity, rounding of nuclei, and increased amount of glycosaminoglycans, correlated to CME. In study III, we developed a computerized 3-D seed-growing MRI technique to measure tendon volume and mean intratendinous signal. This technique showed an excellent inter- and intra-observer reliability. The technique was also used to follow up prospectively the tendon adaptation and healing described in studies IV-VI. In study IV, using serial MRI during a period of 1 year, we evaluated the biological effect of tendon repair following iatrogenic tendon injury by five transversal ultrasound-guided core biopsies employing a needle technique in chronic Achilles tendinopathy. Alterations found during healing, such as tendon volume and intratendinous reactive changes, could be monitored by MR imaging, and subsided as noted in the 7- and 12-month follow-ups. In study V, we evaluated the effect of treatment with a 3-month, daily performed, heavy-loaded calf-muscle strength training program in 25 patients who had been suffering from chronic, painful Achilles tendinopathy. Tendon volume decreased by 14%, and the mean intratendinous signal by 23%. The clinical outcome was improved. In study VI, we revealed tendon adaptation immediately following calf-muscle strength training. An MRI examination within 30min of the performed exercises resulted in increased total tendon volume (12%) and mean intratendinous signal (31%).</p><p><strong>Conclusion: </strong>MRI techniques can be used as an adjunct to clinical eva","PeriodicalId":87169,"journal":{"name":"Acta radiologica.

{"title":"Slipped capital femoral epiphysis. The mechanical function of the periosteum: new aspects and theory including bilaterality.","authors":"L Billing, H G Bogren, B Henrikson, J Wallin","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>This particular ailment has many designations in the literature but none is quite adequate. Here we use the terminology slipped capital femoral epiphysis (SCFE). The anatomy of the proximal femur in all mammals reflects their growth and function. The main forces acting on the head are perpendicular to the growth plate. The thick tear-proof perichondrium-periosteum on the femoral neck is like a stocking attached to the epiphysis and the trochanter region. Growth in length causes a strong tensile stress in the periosteum, pressing the epiphysis against the metaphysis and thus stabilizing the vulnerable growth plate-the periosteum theory. Several factors may diminish the stability of the growth plate. SCFE begins with fissures, which coalesce to a fracture in the growth plate, invisible on a radiograph. As the slip progresses, an increasing angulation between the epiphysis and the remainder of the femur occurs. Weight and muscular forces displace the epiphysis posteriorly in a flexed hip. A rift in the ventral half of the periosteal stocking occurs at the border to the perichondrium and, after that, a longitudinal rift in the periosteum at the anterior midline of the femoral neck. This rift becomes broader as the epiphysis slips posteriorly, withdrawing the ruptured periosteum. Displacement of the epiphysis is due to a rotational slip and tilt, made possible by a compression fracture in the posterior part of the metaphysis. Parts of the periosteum function as reins steering the slip direction and counteracting the displacement. SCFE may be regarded as a pseudoarthrosis in the growing cartilage of the plate. The periosteum theory extended to a pseudoarthrosis theory has been supported by findings at surgery and on true lateral radiographs of usual and unusual cases of SCFE presented in this opus. On a true lateral view, the displacement can be measured as the slipping angle (SA) based on anatomical and geometrical considerations. SA values from 95 normal hips and from 22 contralateral asymptomatic hips from SCFE patients are presented in a histogram and bar graph. Statistically, SCFE is always bilateral, but in about 1/3 of the asymptomatic, contralateral hips, the physis ossifies and closes with SA below 13 degrees, and surgery is not necessary. It is most important that the position of the femur on the X-ray table is exactly defined in two dimensions: 1) the angle between the femoral shaft and the tabletop (angle of elevation), 2) the degree of rotation of the femur around its axis. A precisely defined positioning of the femur is a prerequisite for an exact reproducible measurement of the SA on a true lateral view and is also valuable for the evaluation of radiographic \"signs\". An aid, the Youth Hip Triangle (YHT), has been designed to facilitate positioning of the femur and measurement of SA. YHT is recommended for routine use in every X-ray facility. The method is quick, cost effective and makes it possible to diagnose SCFE in the contralat","PeriodicalId":87169,"journal":{"name":"Acta radiologica.
