“…[11,12] This is already often the case for angiomyolipomas, which due to their fat content, are often readily identified and assigned a radiologic diagnosis. Nonetheless, a small percentage of angiomyolipomas are fat poor, and thus elude diagnosis by this means.…”

“…Though oncocytomas are considered histopathologically similar to chromophobe renal cell carcinoma, again, their enhance patterns seem to differ (see figure 2). Enhancement patterns of renal tumors on computerized tomography have evolved to be a valuable non-invasive technique to help distinguish the different subtypes of renal cell carcinoma [150,151]. Clear cell renal cell carcinomas are often quite vascularized, and often have high Hounsfield unit values in the early phases of the study immediately following contrast administration.…”

“…Although reports have varied in the dose or infusion rate of the contrast agent, scanning timing, and number of scans, clear cell RCC shows heterogeneous marked enhancement in the corticomedullary phase (about 30 s after the beginning of the contrast agent administration) and show fading in the nephrographic (after about 80-100 s) and early excretory (after about 180-300 s) phases [128][129][130][131][132][133][134][135]. In chromophobe RCC, homogeneous moderate contrast enhancement is observed in the corticomedullary phase, but it diminishes thereafter [128,129,132,135].…”

Diagnostic imaging is undoubtedly important in modern medicine, and final clinical decisions are often made based on it. Fortunately, Japan has the highest numbers of diagnostic imaging instruments, such as CT and MRI devices, and boasts easy access to them as well as a high level of diagnostic accuracy. In consequence, a very large number of imaging examinations are performed, but diagnostic instruments are installed in so many medical facilities that expert management of these examinations tends to be insufficient. Particularly, in order to avoid risks, clinicians have recently become indifferent to indications of imaging modalities and tend to rely on CT or MRI resulting in increasing the number of imaging examinations in Japan. This is a serious problem from the viewpoints of avoidance of unnecessary exposure and medical economy. Under these circumstances, the Japan Radiological Society and Japanese College of Radiology jointly initiated the preparation of new guidelines for diagnostic imaging. However, the field of diagnostic imaging is extremely wide, and it is impossible to cover all diseases. Therefore, in drafting the guidelines, we selected important diseases and focused on ''showing evidence and suggestions in the form of clinical questions (CQs)'' concerning clinically encountered questions and ''describing routine imagingThe Japan Radiological Society/Japanese College of Radiology Imaging Guideline was published in 2013.The homepage of the Japan Radiological Society contains information about all CQs of the Japanese Imaging Guideline 2013 as an English version http://www.radiology.jp/english/guideline.html. Radiol (2016) 34:43-79 DOI 10.1007 techniques presently considered to be standards to guarantee the quality of imaging examinations''. In so doing, we adhered to the basic principles of assuming the readers to be ''radiologists specializing in diagnostic imaging'', ''simultaneously respecting the global standards and attending to the situation in Japan'', and ''making the guidelines consistent with those of other scientific societies related to imaging''. As a result, the guidelines became the largest ever, consisting of 152 CQs, nine areas of imaging techniques, and seven reviews, but no other guidelines in the world summarize problems concerning diagnostic imaging in the form of CQs. In this sense, the guidelines are considered to reflect the abilities of diagnostic radiologists in Japan. The contents of the guidelines are essential knowledge for radiologists, but we believe that they are also of use to general clinicians and clinical radiological technicians. While the number and contents of CQs are still insufficient, and while chapters such as those on imaging in children and emergency imaging need to be supplemented, the guidelines will be serially improved through future revisions. Lastly, we would like to extend our sincere thanks to the 153 members of the drafting committee who authored the guidelines, 12 committee chairpersons who coordinated their efforts, six members of the...

“…The cutoff value for highest accuracy for diagnosis of clear cell carcinoma was 83.5 HU for CMP and 64.5 HU for EP. Other factors such as presence or absence of cystic degeneration, tumour vascularity and pattern of enhancement also supplemented this differentiation [Sheir et al 2005]. …”

Differentiation of Renal Cell Carcinoma Subtypes by Multislice Computerized Tomography

Abstract: To differentiate the subtypes of renal cell carcinoma the degree of enhancement is the most valuable parameter. The presence or absence of cystic degeneration, vascularity and enhancement patterns can serve supplemental role in differentiating renal cell carcinoma subtypes.
