Clinical studies on contrast-induced nephropathy (CIN) therefore use a relative or absolute increase in serum creatinine as a surrogate marker. However, there is no generally accepted threshold for increases in creatinine. The lack of consistency in the definition of CIN makes it difficult to compare trials. The serum creatinine level is also only a poor marker of renal function. Increases in serum creatinine after contrast examination are associated with increased mortality, morbidity and longer hospital stays. However, such correlations have been shown only for coronary interventions. Not all cases of renal failure following cardiac angiography are necessarily related to the contrast medium, as in these patients there are several other reasons for loss of renal function. There are no studies showing a correlation between patient outcome and CIN after intravenous administration of contrast media. While the pathophysiology of CIN is not yet completely understood, it most certainly involves the interplay of multiple factors. It is highly likely that direct tubular toxicity of the CM contributes to the aetiology, whereas the role of the physicochemical properties of CM may have been over-interpreted. There is an ongoing controversy as to whether the iso-osmolar CM iodixanol is better tolerated by the kidneys than low-osmolar CM (LOCM). Some randomized trials have demonstrated benefits of this substance. However, to date meta-analyses and registry studies have not shown a consistent picture. In the last few months some randomized trials have been published which have not found an advantage of iodixanol over LOMC, whether administered intra-arterially or intravenously.</p>","PeriodicalId":89151,"journal":{"name":"Imaging decisions (Berlin, Germany)","volume":"11 4","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2008-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1617-0830.2007.00105.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126424032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing emphasis is put on excluding the diagnosis in a safe, efficient and non-invasive manner by determining the pre-test probability of PE. Clinical variables of patients with suspected PE can be combined, either by implicit judgement or by explicit, more standardized clinical decision rules. An ‘unlikely’ probability according to the Wells rule or a ‘low’ clinical probability according to the Geneva rule, in combination with a normal <span>d</span>-dimer test, results in a substantial reduction of the necessity for further diagnostic testing in patients with suspected PE. Interobserver variability is similar for the different clinical decision rules, but is higher for implicit judgement. Comparative studies of the different methods show similar accuracy in the determination of pre-test probability. Using a standardized clinical decision score has advantages over implicit judgement, as even less experienced physicians can adequately assess clinical probability. Modified scores have recently been introduced with clear advantages over the more customary score, but these need further validation.</p>\u0000 </div>","PeriodicalId":89151,"journal":{"name":"Imaging decisions (Berlin, Germany)","volume":"11 3","pages":"8-13"},"PeriodicalIF":0.0,"publicationDate":"2007-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1617-0830.2007.00094.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109167939","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}

Recently the guideline of the Dutch institute for health care improvement (CBO), ‘diagnosis, prevention and treatment of venous thromboembolism (VTE) and secondary prevention of arterial thrombosis’ was published. The diagnostic algorithm in case of suspected VTE starts with a clinical decision rule according to Wells followed by a <span>d</span>-dimer test. These simple, non-invasive and cheap tests, exclude VTE in 25–30% of the patients with a suspected episode of VTE. With a dichotomized clinical decision rule, a ‘likely’ Wells score or an abnormal <span>d</span>-dimer concentration necessitates additional testing, like ultrasonography of the leg veins when deep-vein thrombosis is suspected, or multidetector computerized tomographic scanning in the case of suspected pulmonary embolism.
