The two parallel imaging methods were compared in terms of signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and image artefacts. Image acquisition was started during the administration of a Gd-contrast bolus (0.1 mmoL/kg) followed by a 20-mL saline flush (3 mL/s), and the next perfusion was started at least 15 min thereafter using an identical bolus. The order of perfusion sequences was inverted in every other patient. Both acquisitions had an acceleration rate of 2, and were performed during breath-holding. The SNR, CNR and image quality of the GRAPPA images were significantly better than were those of the TSENSE images. An exception was the lower CNR of GRAPPA when applied after the second bolus. Differences between subjects were larger with GRAPPA perfusion imaging than with TSENSE. The SNR and CNR also varied relatively much between the GRAPPA images, indicating that the diagnostic value of TSENSE may be superior after all.</p>\u0000 </div>","PeriodicalId":89151,"journal":{"name":"Imaging decisions (Berlin, Germany)","volume":"13 2","pages":"43-48"},"PeriodicalIF":0.0,"publicationDate":"2009-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1617-0830.2009.01122.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109162944","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}

None of these tests give adequate information about regional lung function or are sensitive enough to demonstrate subtle changes that may aid in assessing early lung disease status, planning therapy or evaluating response to treatment. There is increasing evidence from recent studies with CT and MRI that current routine measures of lung physiology, (spirometry) and structure (CXR), may not accurately reflect disease progression nor identify early stages of lung disease, often remaining within a normal range even when significant and irreversible pulmonary damage has already occurred. Thus accurate, non-invasive, regional methods of diagnosis and follow up of CF patients based upon imaging endpoints are highly desirable. In this paper, state of the art methods of imaging signs of lung disease in the CF lung are reviewed with discussions on the technical advances in CT, proton and hyperpolarised gas MRI with example images from groups active in the area of CF lung imaging.</p>\u0000 </div>","PeriodicalId":89151,"journal":{"name":"Imaging decisions (Berlin, Germany)","volume":"13 1","pages":"28-37"},"PeriodicalIF":0.0,"publicationDate":"2009-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1617-0830.2009.01125.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109174823","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}
