    Pulmonary sling: Morphological findings. Pre- and postoperative course (1995)

    Notes: Abstract Pulmonary sling (PS) is a congenital condition in which the left pulmonary artery (LPA) arises from the right pulmonary artery (RPA), forming a sling around the trachea causing tracheal compression. The incidence is not so rare as initially thought. Symptoms of severe airway obstruction often begin in the newborn or young infant. Echo-colour-Doppler may reveal the PS but emphysema can mask the typical findings. Deviation of fluid-filled lungs may be detected prenatally. Chest radiographs show unusual air distribution, deviation of heart and mediastinum and altered tracheobronchial angles. Bronchography and bronchoscopy demonstrate the high incidence of associated tracheal anomalies such as cartilagenous rings and long tracheal stenosis. Anterior oesophageal indentation is not always seen in the oesophogram. Magnetic resonance imaging (MRI) and computed tomography (CT) reveal the PS, but cautious interpretation is necessary because of different levels of the anomalous LPA. PS and associated cardiovascular malformations can be clearly detected by angiography. Associated extrathoracic anomalies are common. Early diagnosis and therapy of PS is mandatory and consists of reimplantation of the LPA into the pulmonary trunk and division of the ligamentum arteriosum. The postoperative course may be cumbersome necessitating bronchological interventions. Tracheal resection may be necessary but restenosis is frequent. A one-stage repair has been proposed in such cases and was successfully done in a few reported cases. Relief of respiratory obstruction is often complete when there are no associated tracheobronchial anomalies. Late postoperative course is favourable but respiratory obstructive attacks may occur with decreasing incidence over time and tracheal growth.

    Die Rolle der Radiologie in der Diagnostik und Therapie des zentralen Gallengangskarzinoms (1999)

    Notes: Untersuchungsverfahren der diagnostischen und interventionellen Radiologie beruhen auf dem Einsatz der farbkodierten und kontrastverstärkten Dopplersonographie, der Spiral-Computertomographie, der Magnetresonanzverfahren (MR), wie der MR-Tomographie (MRT) und MR-Cholangio-Pankreatikographie (MRCP), sowie der perkutanen Cholangiographie (PTC). Interventionelle Verfahren mit therapeutischer Option beinhalten den Einsatz der PTCD (Drainage), sowie angiographischer Verfahren mit Embolisationstechniken zur Induktion einer Leberregeneration. Die moderne bildgebende Diagnostik erlaubt die exakte Bestimmung der Höhe der Obstruktion und der Ausdehnung des Tumors entlang der intrahepatischen Gallenwege. Mit der MRCP gelingt der Nachweis einer malignen Gallenwegsstenose mit einer Sensitivität von 86% und einer Spezifität von 98%, wobei die korrekte Klassifikation der Läsion als maligne in 50–80% der Fälle gelingt. Die moderne MR-Technologie der MRT mit MRCP stellt die optimale bildgebende diagnostische Strategie zur Abklärung zentraler Gallengangskarzinome dar, ergänzt durch die invasive ERC und in Einzelfällen durch die PTC. Interventionelle Embolisationstechniken zur Leberregeneration erhöhen den Anteil primär kurativ reserzierbarer Patienten.

    Notes: Abstract Portal vein thrombosis (PVT) is an infrequent complication following hepatic transplantation. However, deterioration of liver function and accompanying complications may be life threatening. Several attempts of surgical or percutaneous transhepatic procedures have been described. In some cases high dose fibrinolytic regimens have been successful. We describe the case of a male liver recipient with recurrent liver fibrosis due to hepatitis B reinfection and late portal vein thrombosis 45 months after transplantation. Complete recanalization was achieved using systemic low dose recombinant tissue plasminogen activator (rt-PA).

    Description / Table of Contents: Abstract The employment and benefit of conventional chest X-ray examination in traumatic patients have been reported on by several publications. Up to now only a few studies have been published which compare the diagnostic impact of conventional chest X-ray and CT in patients with thoracic trauma. In a retrospective study in 70 patients with multiple trauma sensitivity and specificity of chest X-ray and CT of the thorax are evaluated. Evaluation was performed by 2 independent and experienced radiologists. The readers were blinded to the results and each examination was evaluated separately. The results showed a higher sensitivity of the thoracic CT examination than conventional chest X-ray. The CT of the thorax in patients with multiple trauma is an important adjunct to conventional chest X-ray and is more sensitive in the depiction of lung parenchyma as well as vascular injuries.
    Notes: Zusammenfassung Der Einsatz der konventionellen Röntgenthoraxuntersuchung bei polytraumatisierten Patienten ist in der Literatur bereits vielfach beschrieben worden. Es sind bisher jedoch nur wenige Studien zum Vergleich der diagnostischen Aussagekraft von konventionellen Thoraxaufnahmen und Thorax-CT bei Thoraxtraumen publiziert worden. In einer retrospektiven Auswertung konventioneller Röntgenaufnahmen des Thorax und der Thorax-CT bei 70 polytraumatisierten Patienten wurden die Sensitivität und Spezifität hinsichtlich pathologischer Thoraxbefunde ermittelt. Die Auswertung erfolgte durch zwei erfahrene Radiologen, wobei beide bildgebenden Verfahren getrennt voneinander und in Unkenntnis des Vorbefundes bewertet wurden. Die Auswertung des Kollektivs ergab eine höhere Sensitivität der CT-Untersuchung gegenüber der konventionellen Röntgenthoraxaufnahme bei polytraumatisierten Patienten; sie stellt somit eine wichtige Ergänzung zur konventionellen Röntgenthoraxaufnahme dar und ist sensitiver in der Erfassung von thorakalen Verletzungen, insbesondere im Bereich des Lungenparenchyms und des Mediastinums mit Gefäßen.

    Description / Table of Contents: Abstract Traumatic injuries of the cervical spine are of significant medical and socioeconomic importance. The potential of different imaging modalities have to be known to select the optimal imaging tool. The differentiation between functional handicaps without detectable lesions and traumatic lesions is sometimes difficult. The diagnostic work-up of traumatic cervical spine lesions is based on conventional X-ray in 2 planes. The value of the different imaging modalities for the diagnostic work-up of traumatic cervical spine lesions will be discussed.
    Notes: Zusammenfassung Traumatische Verletzungen der Halswirbelsäule sind von erheblicher medizinischer und sozioökonomischer Bedeutung. Um die heute zur Verfügung stehenden bildgebenden Verfahren optimal einsetzen zu können, ist die Kenntnis der Wertigkeit der einzelnen Verfahren von entscheidender Bedeutung. Eine besondere Schwierigkeit der Diagnose liegt in der Abgrenzung möglicher struktureller Läsionen von rein funktionellen Beeinträchtigungen. Basierend auf konventionellen Röntgenaufnahmen in zwei Ebenen, wird cin Stufenschema zur Diagnostik traumatischer Veränderungen im Halswirbelsäulenbereich vorgestellt und die Wertigkeit der einzelnen bildgebenden Verfahren diskutiert.

    Applications of specialized coils for high-resolution MRI on a whole-body scanner (1996)

    Notes: Abstract To investigate the application of a mini-coil surface system for high-resolution MRI, 60 volunteers were examined in a 1.5-T whole-body scanner. Two replaceable probe heads were available: a circular 2.5-cm coil and a quadratic 5-cm coil, both of which were placed directly on the skin. The skin layers, Achilles tendon and finger joints were examined with the 2.5-cm coil and a FOV of 25 × 25 mm2. A matrix of 256 × 256 pixels resulted in a pixel size of 0.098 × 0.098 mm2. For imaging of the carpal tunnel, the 5-cm coil was used in transverse orientation. The FOV was 50 × 50 mm2 so that a matrix of 256 × 256 pixels led to a pixel size of 0.195 × 0.195 mm2. The resulting spatial resolution permitted visualization of the epidermis, dermis and subcutis, resulting in clear definition of anatomical detail of the musculoskeletal system. MRI measurement of skin-layer thickness did not correlate with histometric data (p〈0.05). This discrepancy was due in part to shrinkage of the tumor specimen on histologic preparation. Other causes include the motion artifacts and the limited accuracy of determining thickness on the MRI display unit.
