Several radiologic methods are used for assessment of these diseases. Conventional films of the parotid and submandibular glands demonstrate opaque stones in the duct system, whereas sialography depicts nonopaque stones, provides additional information on the position of the stones, and differentiates it from other calcific densities near the duct system, as well as providing information concerning ectasia of the ducts. CT has been used for evaluating mass lesions and extraglandular inflammatory disease, including abscesses. CT also depicts stones that may not be visible on conventional films. MR imaging has become an important modality in the diagnosis and definition of benign and malignant tumors and cysts and it will probably replace CT as the primary imaging modality for the assessment of these lesions. Gadolinium may be used in the examination, especially if a malignant tumor is suspected (because of irregularity and intraglandular extension).","PeriodicalId":77090,"journal":{"name":"Current opinion in radiology","volume":"4 1 1","pages":"117-22"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/9781119218739.ch13","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42173766","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}

{"title":"Nonmammographic breast imaging techniques.","authors":"S H Heywang-Köbrunner","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Significant progress in early detection of malignancy has been achieved by the improvement of mammographic technique, the introduction of quality control, the demonstration of benefits from screening, and appropriate application of supplementary methods such as ultrasound, cytology, and stereotaxis. Certain problems in breast imaging, however, are still unsolved. These include early detection and exclusion of malignancy without microcalcifications in mammographically dense tissue (particularly in younger women), the still-limited accuracy of mammographic signs, and the management of diagnostic problems after surgery, radiation therapy, or silicone implants. Therefore, research is needed to further improve diagnostic capabilities. The research can be subdivided into different approaches: 1) further development of the mammographic technique (digital luminescence radiography); 2) evaluation of techniques that image other physical tissue properties (sonography, thermography, trans-illumination, CT, non-contrast-enhanced MR imaging, biomagnetism, biostereometry, and ductoscopy); 3) investigation of techniques that image metabolic changes (MR spectroscopy, positron-emission tomography) or metabolism-induced differences in perfusion or vascularity (Doppler ultrasound, contrast-enhanced MR imaging); and 4) development of techniques that attempt tissue diagnosis using monoclonal antibodies. Among these techniques, digital luminescence radiography and contrast-enhanced MR imaging are the most developed and the most promising. They are at the threshold of becoming clinically important. Doppler ultrasound could be useful for certain indications. Whereas MR spectroscopy, positron-emission tomography, the search for appropriate antibodies, and possibly transillumination, ductoscopy, and biomagnetism offer interesting new aspects for research, the value of CT, thermography, and biostereometry is not yet established.</p>","PeriodicalId":77090,"journal":{"name":"Current opinion in radiology","volume":"4 5","pages":"146-54"},"PeriodicalIF":0.0,"publicationDate":"1992-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12694062","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}
