Manufacturers provided efficient technological tools on CT to achieve a significant radiation dose reduction while maintaining a diagnostic quality of the image. Yet, the implementation of all these improvements allowing the low-dose (LD) and ultra-low-dose (ULD) CT imaging has difficulty to take hold. Radiologists do not easily accept to read images with a degraded image quality although diagnostic. As every cultural change, even in a radiological department the acceptation of the LD/ULD-CT imaging requests time.

We named it “Radiophilia”. It can be defined as “unnecessary radiation exposure due to misunderstanding and underestimation of risk perception, risk conception and risk communication among healthcare employees involved in medical radiation imaging”. Radiophilia is not a term to describe a phenomenon, but it is an inconvenient truth that is not justified any way. We discus more on Radiophilia and address main reasons that may lead to this truth.","PeriodicalId":90030,"journal":{"name":"OMICS journal of radiology","volume":"2016 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70852888","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}

Two experienced radiologists reviewed the size, number, and boundaries of the HCC lesions, portal invasion, and tumor metastasis on MDCT and MRI images in consensus. Then the performance of Gd-EOB-DTPA-enhanced MRI and MDCT on staging HCC lesions was compared through statistical analysis. The classification of the Barcelona Clinic Liver Cancer (BCLC) stage was also evaluated. \u0000Results: HCC lesions in five patients were detected on Gd-EOB-DTPA-enhanced MRI only. Of the other 107 patients, 21 (19.6%) were in BCLC stage 0, 49 (45.8%) in BCLC stage A, 14 (13.1%) in BCLC stage B, and 23 (21.5%) in BCLC stage C on MDCT. On Gd-EOB-DTPA-enhanced MRI, 12 (11.2%), 48 (44.9%), 17 (15.9%), and 30 (28.0%) patients were classified as BCLC stages 0, A, B, and C, respectively. The two methods differed significantly in staging HCC patients (χ2=16.444, P=0.006). \u0000Conclusion: This study suggests that Gd-EOB-DTPA-enhanced MRI provides more accurate information than MDCT for characterizing and staging HCC which will help to choose accurate treatment strategy.","PeriodicalId":90030,"journal":{"name":"OMICS journal of radiology","volume":"2016 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-7964.1000222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70849693","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}
