Two new techniques have emerged: arterial spin labeling (ASL) MRI and diffusion MRI. Both have the theoretical advantage of more accurately directly demonstrating neuronal activation compared to BOLD imaging, resulting in improved spatial and temporal resolution. ASL is a perfusion sequence using labeled arterial protons as an endogenous perfusion agent. In spite of methodological difficulties, quantitative CBF measurements are possible. ASL is less susceptible to venous contamination than BOLD and more reproducible. Diffusion MRI evaluates neuronal activation at the cellular level with the prospect of excellent spatial resolution. The main limitations for both techniques are the technical difficulties in the acquisition and the low SNR. AS such, ASL is not widely used clinically and diffusion remains in the field of research. However, the increasing availability of 3T MR systems coupled with multi-channel surface coils and improved postprocessing techniques should improve the detection of the brain activation signal. It is thus possible that these techniques could become clinically available either in complement to or as a replacement for BOLD imaging.</p></div>","PeriodicalId":14813,"journal":{"name":"Journal De Radiologie","volume":"92 10","pages":"Pages 878-888"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jradio.2011.04.016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30210018","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}

All persistent unilateral nipple lesion should be viewed with suspicion and Paget's disease of the nipple should be considered. The diagnosis is established by nipple scrape cytology. It is a rare variant of ductal carcinoma in situ. The breast imaging work-up should include a search for an underlying malignancy, present in over 80% of cases, not infrequently multifocal. Preoperative MRI is useful if breast conservative surgery is contemplated because of the high rate of occult malignancy on mammograms and ultrasound. Erosive adenomatosis of the nipple is a benign process that may simulate Paget's disease isolated to the nipple. Less frequently, pagetoid basal cell carcinoma, Bowen's disease and melanoma may be more difficult to differentiate clinically and share the unilateral and chronic features of Paget's disease. Biopsy is needed for diagnosis. Cutaneous extension of a breast cancer is rare but should be suspected in patients with retraction and/or fixed nipple. Eczema is characterized by the bilateral nature of the process, the absence of nipple deformity, the presence of flare-ups and the favorable response to local steroid therapy.</p></div>","PeriodicalId":14813,"journal":{"name":"Journal De Radiologie","volume":"92 10","pages":"Pages 889-898"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jradio.2011.07.010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30210019","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}
