Abstract AIM: Clinical and statistical study analysing factors with influence on success rates, procedure-related complications, and long-term results for patients who underwent angioplasty of the crural arteries. MATERIAL AND METHODS: Retrospectively we evaluated all patients who underwent angioplasty of the crural arteries due to critical chronic limb ischemia or severe claudication in the time period from 1/2002 to 12/2005. These patients were contacted in the time period from 1/2009 to 12/2010, and a follow-up examination including angiography was performed or telephone interviews were conducted with pati...

[Radiation protection in interventional radiology].
Abstract The application of ionizing radiation in medicine seems to be a safe procedure for patients as well as for occupational exposition to personnel. The developments in interventional radiology with fluoroscopy and dose-intensive interventions require intensified radiation protection. It is recommended that all available tools should be used for this purpose. Besides the options for instruments, x‑ray protection at the intervention table must be intensively practiced with lead aprons and mounted lead glass. A special focus on eye protection to prevent cataracts is also recommended. The development of catara...

[Subintimal recanalization : Indications, technique and results].
This article gives an overview of the current importance of so-called subintimal recanalization in the lower extremities. STANDARD RADIOLOGICAL METHODS: The primary technical goal of endovascular interventions in the lower extremities is the endoluminal restoration of blood circulation from the iliac arteries into the feet. METHODICAL INNOVATIONS: If endoluminal recanalization of e.g. high-grade flow-relevant stenoses or chronic total occlusion (CTO) is technically not possible, subintimal recanalization is a promising option and the only remaining minimally invasive alternative. During subintimal recanalization ...

[Drug-coated balloons in the treatment of peripheral artery disease (PAD) : History and current level of evidence].
CONCLUSIONS: Major advantages of the DCBs lie in leaving no stent scaffold behind, the immediate release of high drug concentrations with a single dosage, their efficacy in areas, where stents have been contra-indicated until now and its use for secondary interventions. As their effect seems to be limited in severely calcified lesions, prior plaque preconditioning or removal could be advantageous. First positive results data supporting this hypothesis do exist.

[Principles and applications of susceptibility weighted imaging].
Abstract BACKGROUND: Susceptibility-weighted imaging (SWI), initially developed to provide an improved method for cerebral magnetic resonance (MR) venography, is now an integral part of neuroradiological diagnostics and is steadily gaining importance in non-cerebral imaging. PRINCIPLES: Tissue-inherent susceptibility differences generate a local magnetic field in which the dephasing of signal-producing protons occurs. This leads to a characteristic phase shift that can be used as a means to enhance contrast in the well-known T2*-weighted imaging. APPLICATION IN CLINICAL ROUTINE: Many medically relevant p...

[Stent-assisted recanalization of femoropopliteal arterial occlusive disease : Influence of stent design on patency rates].
CONCLUSION: The published data are heterogeneous and comparative studies for different stent designs are completely missing. Over the past decade the patency rates after femoropopliteal stenting could be improved. According to available data stenting of short lesions  6.4 cm. Due to the heterogeneity of published data a clear benefit for a specific stent design is not obvious; however, data for interwoven stents are promising and show a tendency towards improved patency, at least for certain lesions. Randomized controlled comparative trials are needed to confirm this result. PMID: 26842999 [PubMed - as sup...

[Imaging of the head and neck region].
Abstract Tumors of the head and neck are predominantly squamous cell carcinomas and those of the salivary glands are predominantly adenocarcinomas, adenoid cystic carcinomas and mucoepidermoid carcinomas. In 2011 the incidence of tumors of the oral cavity and pharynx in Germany was 6839 (5026 male and 1813 female) and of the larynx 1878 (1642 male and 236 female). The incidence of tumors of the nose and paranasal sinuses (467) and salivary glands (470) were much lower ( www.krebsdaten.de/abfrage ). The primary aim of imaging in head and neck cancer is staging of the disease and a precise assessment of tumor invasi...

Abstract BACKGROUND: Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) technique that was established in the clinical routine primarily for the detection of brain ischemia. In the past 15 years its clinical use has been extended to oncological radiology, as tumor and metastases can be depicted in DWI due to their hypercellular nature. PRINCIPLES: The basis of DWI is the Stejskal-Tanner experiment. The diffusion properties of tissue can be visualized after acquisition of at least two diffusion-weighted series using echo planar imaging and a specific sequence of gradient pulses. CLINIC...

Abstract METHOD: Functional magnetic resonance imaging (fMRI) is a non-invasive method that has become one of the major tools for understanding human brain function and in recent years has also been developed for clinical applications.

Using high-field MR systems and increasingly dedicated statistics and postprocessing, activated brain areas can be detected and superimposed on anatomical images. Currently, fMRI data are often combined in multimodal imaging, e. g. wit...

l S Abstract Cerebral vasculitis can have a variety of origins. Furthermore, there are no vasculitis-specific symptoms or imaging signs and vasculitis of the CNS can mimic many other neurological diseases, which require different treatment approaches. Thus, the clinical and radiological diagnosis of cerebral vasculitis is challenging. Magnetic resonance imaging (MRI) and MR angiography (MRA) should be the radiological imaging methods of choice to assess the degree of parenchymal damage and to detect vessel wall changes. If the results are unclear digital subtraction angiography (DSA) should be pursued in order to ...

Most patients are asymptomatic and the diagnosis is an incidental finding on chest X-ray or during clarification of unspecific symptoms, such as fatigue or cough. In approximate...

Abstract Acute extracranial internal carotid artery (ICA) occlusions resulting in ischemic stroke are different from other forms of acute occlusions of cerebral vessels. The pathophysiological process involved in occlusion of the extracranial ICA is similar to processes observed in acute occlusion of the coronary arteries. The occluded segment of the ICA predominantly consists of an atherosclerotic plaque and a superimposed thrombus. Although the value of endovascular therapy has been established for intracranial occlusions, the acute treatment of extracranial ICA occlusions has not yet been proven in randomized s...

Although prospective studies are lacking retrospective studies have shown that the risk of iatrogeneous vessel injuries without global anesthesia is not increased but outcomes in case of conscious sedations are better compared with intubation and general anesthesia.
