It was found that AML detection in plain scan tomography requires a fat fraction of more than 50%. Angiomyolipomas with a fat fraction of less than 50% need computerised serial densitometry to enable differentiation from other unidentified tumours. The criteria to be used in these cases are 1) the low curve level and 2) the presence and slim shape of the initial circulatory peak. The principle of using standard densitometric curves of single tissue components and cells in in vivo tissue analysis might gain significance in the noninvasive, computerised qualitative and quantitative analysis of the composition of tumours and organs thus creating new possibilities for the diagnosis, follow-up and prognosis of diseases.</p>","PeriodicalId":76504,"journal":{"name":"Rontgen-Blatter; Zeitschrift fur Rontgen-Technik und medizinisch-wissenschaftliche Photographie","volume":"43 12","pages":"516-8"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13438198","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}

It is concluded that in pubertal gynaecomastia it is necessary to determine whether the disease is merely a temporary fibrosis that will heal by itself, or whether it is a sign of some other, graver disease. On the other hand, the state of the testicles and the scrotum should be considered in every case.
