However, it has a slight but discrete complication rate. With the introduction of multidetector computed tomography (MDCT), the coronary system could be evaluated non-invasively. The limited temporal and spatial resolution of the first MDCT scanners made the examination quality of scanning of patients with high, increasing or irregular heart rates or patients with stents, clips or severely calcified arteries less predictable. The introduction of dual-source computed tomography (DSCT) might constitute a promising new concept for cardiac CT. In this study, we present our first experience with DSCT. We investigated seven patients for different indications with DSCT. Image quality was reliable in all patients despite the presence of high heart rates (up to 105 beats per minute), heavy calcifications and surgical clips. DSCT showed stenoses which were not detected on CAG. Regarding the fact that DSCT not only offers morphological information of the coronary vessel wall and lumen but also delivers all standard functional cardiac parameters, it has true potential as a routine diagnostic tool in the cardiac diagnostic workup. In conclusion, first results of DSCT show high-quality, consistent cardiac and coronary imaging independent of heart rate and patient condition.

When arthroscopy finally is undertaken after a lot of discussion and delay caused by the reportedly normal MRI, the clinical suspicion is verified. The opposite situation may of course also occur. A clinician usually refers to MRI when the clinical diagnosis is unclear. However, among professional clubs in the UK the referral to a tertiary specialist is in many cases accompanied with an already undertaken MRI. In this review, we demonstrate several illustrative cases, where MRI has led to unnecessary management delays. The review focuses on meniscus and focal cartilage injuries. We suggest a range of possible solutions, which may improve the situation. There are several controversies to be addressed. First, detailed communication between the clinician and radiologist are often hampered by formal procedures. A referral is sent to the Radiology Department and a radiographer will perform a routine MRI protocol. The referral question may not always point to the correct injury, and is depending on the experience of the clinician. Usually, the radiologist is not present during scanning and instead puts together a protocol and subsequently reports on the images without having seen the injured player. Secondly, the use of different routine protocols for investigation of different structures is often not known in detail by the clinician. Thirdly, there is often a lack of standardized reporting of exact location, size and severity of focal cartilage injury in relation to the patients sporting demands. Furthermore, the quality of healed cartilage in a treated focal defect is of course of vital interest for allowing return to sport. Last but not least, inability to verify dynamic instabilities and structural behaviour during movement of the injured knee decreases the clinical value of MRI when compared with arthroscopy for a number of common sport injuries of the knee.</p>","PeriodicalId":89151,"journal":{"name":"Imaging decisions (Berlin, Germany)","volume":"10 1","pages":"2-7"},"PeriodicalIF":0.0,"publicationDate":"2006-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1617-0830.2006.00062.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109173192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fractures of the proximal tibia, particularly those that extend into the knee joint, are serious injuries that frequently result in functional impairment. Recent advances in cross-sectional imaging, particularly in computed tomography (CT), have given this modality a prominent role in the detection and classification of fractures in and around the knee. With the advent of high-performance multi-detector CT, isotropic data sets can be generated with subsecond gantry rotation times and submillimetre slice thickness.
