[What does the clinician expect from the radiologist regarding cartilage-specific imaging?]
This article highlights the importance of a radiologist's role in different constellations. PRACTICAL RECOMMENDATIONS: In the case of acute injuries, it is crucial to recognize osteochondral flakes, cartilage delamination, subchondral bone bruising and fractures as well as concomitant injuries. These findings must be instantly communicated to the practitioner. In the case of chronic cartilage damage, grading the extent and size of the damage is decisive in choosing the appropriate therapy method. Possible causes and accompanying injuries must also be analyzed and, if necessary, addressed. Direct communication wit...

[Magnetic resonance imaging following cartilage repair of focal chondral lesions].
itz C Abstract BACKGROUND: Focal cartilage lesions are common pathologies of weight-bearing joints. Clinical presentation ranges from asymptomatic patients to severe, pain-related movement deficits. Moreover, focal chondral lesions are risk factors for the development of osteoarthritis. There are various treatment options involving both surgical and nonsurgical treatments. Musculoskeletal radiologists should be aware of the various surgical options as well as the postsurgical imaging characteristics to depict whether the encountered imaging findings reflect the normal postoperative course or are indicative of a&nb...

Abstract PURPOSE OF IMAGING: Imaging plays a major role in the diagnosiss, treatment indication, and prognosis of acute ischemic stroke. RECENT STUDY RESULTS: Recent studies have proved the safety and effectiveness of thrombolysis and endovascular thrombectomy based on the individual combination of imaging and patients clinical information even beyond the classical time-windows. In these cases, magnetic resonance imaging and perfusion-imaging can provide additional and important information. STANDARD DIAGNOSTICS: Nevertheless, computed tomography with and without contrast media still represents the ...

Abstract CLINICAL ISSUE: Acute strokes caused by tandem occlusions include an atherosclerotic or dissective stenosis/occlusion of the extracranial internal carotid artery (eICA) in combination with an intracranial vessel occlusion. STANDARD TREATMENT: Endovascular treatment can be technically challenging but is definitely superior to intravenous thrombolysis alone and achieves good clinical results comparable to those from solitary intracranial occlusions. LATEST STUDY RESULTS: Although there are still no prospectively randomized studies on endovascular treatment for tandem occlusions, currently availabl...

[Ultrasound diagnostics of extracranial cerebral arteries].
Abstract Color-coded duplex sonography (CCDS) remains the primary angiological method for most clinical cerebrovascular problems. The application of ultrasound is a non-invasive, cost-effective and arbitrarily repeatable examination technique. Simultaneous acquisition of morphologic B‑mode images and hemodynamic parameters with high temporal and spatial resolution is unequalled by any other neurovascular imaging modality. The correct and reproducible use of CCDS requires knowledge of technical details and adequate examination techniques. Its multiparametric approach uses main and additional criteria to dete...

The DWI sequences allow insights into different microstructural diffusion properties of water molecules in tissues depending on the sequence modification used and enable visual and quantitative analysis of the acquired imaging data. In DWI, the application of intravenous gadolinium-containing contrast agents is unnecessary and only the mobility of naturally occurring water molecules in tissues is quantified. These characteristics predispose D...

Abstract Endoscopic interventions in the biliary system are defined by the elimination of an outflow obstruction such as in choledocholithiasis or the optimization of bile flow by means of stent drainage. Exclusive use of diagnostic endoscopic retrograde cholangiography (ERC) is now obsolete, but due to its minimally invasive approach, therapeutic ERC is the method of choice for intervention in appropriate indications. If access to the biliary system via the papilla is not possible, approaches as guided by endoscopic ultrasound appear to be a valid option for the experienced endoscopist. PMID: 30789996 [...
