Abstract:
In 326 patients abdominal contrast radiographs were compared to digital luminescence radiographs (DLR) and conventional screen-film system ones. The digital exposure dose was 50% of the conventional. In DLR, 2 different types of postprocessed images were obtained from each data set. A display with low spatial frequency enhancement filtered to look like a conventional radiograph was compared to a display with high spatial frequency enhancement. Conventional and DLR images were evaluated randomly and separately by 4 radiologists by means of a questionnaire. DLR proved to be diagnostically equivalent to the conventional technique with the exception of a slightly diminished visibility of the mucosal pattern. High spatial frequency enhancement did not provide additional diagnostic information and should be dispensed with in abdominal examinations.

Abstract:
The introduction of picture and archiving communicating systems is currently being evaluated in several institutions. We decided, as an intermediate step, to see if image quality after transferral to a personal computer (PC) is sufficient for the diagnostic needs in an intensive care unit. Seventy-five portable digital chest radiographs were studied both as hard-copies and on a monitor after transferral to a PC. Two chest radiologists and one anesthesiologist reviewed the examinations. Our intention was to evaluate if everything that is routinely checked by the anesthesiologist is demonstrable after electronic transfer to a local workstation. We found practically no difference between the performance of monitor and film for the whole material.

Abstract:
An Yucatan Micropig(R) wurde überprüft, ob die systemische Applikation von Wachstumshormon (GH) in der Lage ist, die Regeneratkonsolidierung bei der Distraktionsosteogenese signifikant zu beschleunigen. Es erfolgte die Entwicklung eines speziellen externen Fixateurs (Halbringf.) mit welchem biomechanische in-vivo Messungen durchgeführte werden konnten. Ebenso wurden serologische, sonographische, röntgenologische, computertomographische, histomorphometrische und post mortem biomechanische Untersuchungen entwickelt und durchgeführt. Die Applikation von rekombinantem spezies-spezifischen Wachstumshormon bei der Distraktionsosteogenese zeigte bei dem von uns gewählten Tiermodell eine signifikante Beschleunigung der Regeneratkonsolidierung. Die biomechanischen Messungen ergaben eine mehr als verdoppelte Steifigkeit und Festigkeit der distrahierten Tibiae nach nur 10 Tagen Konsolidierungszeit im Vergleich zur Kontrollgruppe. Die CT erbrachte für die mit GH behandelten Tiere einen signifikant erhöhten Mineralisierungsgrad im Regenerat, zum gleichen Ergebnis kam die digitale Lumineszenzradiographie und die sonographische Vermessung des Regeneratdurchbaus. Somit zeigten alle Meßmethoden eine deutliche Beschleunigung der Regeneratkonsolidierung durch systemisch appliziertes GH. In den serologischen Untersuchungen fand sich eine signifikante Korrelation zwischen dem Serumspiegel der b-ALP und dem des IGF-I. Dies ist ein Hinweis darauf, dass die Wirkung des Wachstumshormons auf das Regenerat durch seinen Mediator IGF-I bedingt ist.<br>To investigate the effect of systemic growth hormone (GH) application experiments were performed in a micropig animal model. Systemic daily s.c. injection of species-specific recombinant GH was investigated in Yucatan micropigs to evaluate the effect on intramembranous bone formation in distraction osteogenesis. Quantitative computed tomography (qCT), quantitative ultrasound, digital luminescence radiography, biomechanical in-vivo and post mortem testing, serological investigations as well as histomorphometric analyses were performed to investigate differences in regenerate formation. Systemic GH administration significantly increased in the present animal model the torsional stability of the regenerate in-vivo as well as post mortem in comparison to the contralateral side. Also all additional methods showed an accelerated regenerate consolidation in case of GH application. Systemic Insulin-like growth factor -I levels correlated well with the bone specific alkaline phosphatase levels. This may indicate, that the effect of GH on the distraction osteogenesis is IGF-I mediated.

Abstract:
Computed radiography or CR has been used in the Radiography NDT industry for quite a long time. Use of CR in the pressure vessel welds has not been so popular or common industry practice, particularly in this region, may be because of cost and to some extent acceptance by the client. However ASME BPV Code has already approved use of CR and DR techniques in pressure vessel welds in place of film Radiography. The latest edition of ASME BPV Code Sec V has added some new requirements for qualification and certification of NDT personnel in Computed Radiography (ASME Sec V: 2015 Article I; Mandatory Appendix II). Typically, as we all know, CR or computed radiography uses a storage phosphor imaging plates, known as SPIP, which emits photo-stimulable luminescence in place of Silver Bromide coated films, that luminescence or light radiation is amplified by photomultiplier tubes and passes through A/D converter and several filters which produce an image on the suitable computer monitor. Most of the requirements of ASME Sec V for CR are similar to that of film radiography except in some cases as resolution, brightness and contrast in place of density and contrast used for film radiography. Although it requires expertise for processing the images, but the technique is very useful in replacing film radiography particularly in terms of chemical hazards and environmental issues of film processing, exposed film archiving and computer assisted image enhancement. But more than in traditional radiography, the use of digital images is a trade-off between the speed and the required quality. Better image quality is obtained by longer exposure times, slower phosphor screens and higher scan resolutions. Therefore, different kinds of storage phosphor screens are needed in order to cover every application. ASTM E2007 &amp; E2033 provide excellent information and guidance of the process and application of computed radiography. Here in this presentation, we have described our understanding and experience of using computed radiography in lieu of film radiography for a pressure vessel meeting all the requirements of ASME Code.
