Transpupillare Thermotherapie (TTT) zur Behandlung von Aderhautmetastasen
2001
Die transpupillare Thermotherapie (TTT) wird erfolgreich zur Behandlung kleiner Aderhautmelanome am hinteren Augenpol eingesetzt [9, 13, 14]. Wir berichten uber die erfolgreiche Behandlung von Aderhautmetastasen mittels TTT unter intravenoser Gabe von Indozyaningrun (ICG). Bei 3 Patienten mit systemisch metastasierenden Karzinomen (Osophagus-, Bronchial- und Mamma-Ca) wurden Aderhautfiliae in 4 Augen mit jeweils einer Sitzung TTT behandelt. Verwendet wurde ein Diodenlaser (810 nm) und Spotgrose 2–3 mm. Die Laserleistung (im Mittel 0,75W) wurde beginnend bei 0,3W in 50 mW Schritten fur jeweils 1 Minute erhoht, bis die Tumoroberflache eine grauweise Odembildung zeigte. Jeweils 1 Minute nach T…
Communicating with the hepatobiliary surgeon through structured report
2019
Communicating radiological findings to hepatobiliary surgeons is not an easy task due to the complexity of liver imaging, coexistence of multiple hepatic lesions and different surgical treatment options. Recently, the adoption and implementation of structured report in everyday clinical practice has been supported to achieve higher quality, more reproducibility in communication and closer adherence to current guidelines. In this review article, we will illustrate the main benefits, strengths and limitations of structured reporting, with particular attention on the advantages and challenges of structured template in the preoperative evaluation of cirrhotic and non-cirrhotic patients with fo…
Hepatocellular carcinoma: Diagnostic imaging criteria
2020
The diagnosis of hepatocellular carcinoma (HCC) can be reached noninvasively on imaging in patients at high risk as discussed in chapter “Hepatocellular carcinoma: Diagnostic Guidelines.” In this chapter, we describe the CT and MR imaging criteria more commonly used in the guidelines for the diagnosis and management of patients with HCC, including arterial phase hyperenhancement, washout, capsule, growth, and hypointensity on hepatobiliary phase MR imaging. The provided definitions are based on the latest version (v2018) of the liver imaging reporting and data system (LI-RADS) document (American College of Radiology 2018, https://www.acr.org/Clinical-Resources/Reporting-and-Data-Systems/LI-…
Posterior ‘Motion Preserving’ Procedures (Frykholm)
2019
Cervical radiculopathy from degenerative disease is a common problem with an incidence of 0.83–1.79 per 1000 person years. It can be caused by a cervical disc herniation, bony foraminal stenosis or spinal canal stenosis. Upon failure of conservative therapy or a significant motor deficit surgical treatment is indicated. A posterior cervical foraminotomy is one surgical option for the treatment of selected patients with lateral cervical disc herniations.
Pulsed radiofrequency energy device (PEAK plasmablade™) and CustomBone® Cranioplasty: an appealing surgical rendez-vous
2019
Background: CustomBone® prosthesis is a widely recognized effective and successful technique for the reconstruction of cranial bone defects. Prior the cranioplasty implant, meticulous dissection wi...
Die Röntgendigitalanlage als Instrument zur kinematischen Untersuchung der Schulter — Eine Untersuchung zur Strahlenbelastung - Digital Radiography a…
1991
The radiation exposure during biomechanical investigation of the shoulder joint done with a digital radiography system (Polytron 1000 VR - Siemens) was measured experimentally. Total radiation dose and surface dose were determined by phantom measurements. The radiation exposure per image is about 1/6 to 1/7 of that of a conventional study. The digital radiography system used is thus suitable for kinesiologic studies of large joints in healthy volunteers.

Radiotherapy for Graves’ ophthalmopathy
2000
The interest in the treatment of benign diseases with radiation therapy has grown particularly in the Western part of the world. In 1996, a questionnaire was sent to 1348 institutes worldwide listed in the directory of the Society for Therapeutic Radiology and Oncology asking whether the respondents considered a list of 28 most common benign disorders as being a good indication for orbital radiotherapy.1 Questions concerned the frequency of such treatments and the treatment schedules used. The prevention of keloid formation was the most widely accepted indication, followed by Graves’ ophthalmopathy. Thus, radiotherapy for this orbital disorder is generally accepted and applied worldwide.
Highlights and essentials from the first "experts-live" course of the EuroCTO club
2010
Chronic total occlusions (CTOs) are frequently encountered during diagnostic coronary catheterisation. However, there is still confusion regarding the indication for percutaneous coronary intervention (PCI) in this lesion subset, mainly because it is cumbersome and the prognostic impact of revascularisation in these patients remains unclear. Many studies have now shown the long term clinical benefits after CTO PCI1-3; still, with procedural complexity, high radiation exposure to both the patient and the operator, high costs and lower procedural success rates, most patients with CTO are managed medically or referred for bypass graft surgery – regardless of the severity of symptoms and extent…
