内容紹介
近年、肝組織性状診断におけるCT・MRIの進歩はめざましく、線維化や脂肪化の定量などそれぞれの特性を生かした信頼性の高い診断が可能となりつつある。一方超音波検査に関しては、微細構造の空間分解能と実時間性に優れ、可搬性に冨み、万人が操作可能、経済性等々、いまだ他の追随を許さない利点が沢山あり、これらは臨床の場で大変役に立つものである。今回我々は、びまん性肝疾患の中の脂肪肝のBモード超音波にフォーカスし、その診断の現状と問題点について述べる。
Recently,remarkable technological advances have been made in computed tomography and magnetic resonance imaging for histological diagnosis of liver disease.Utilizing the unique features of each imaging modality makes it possible to establish highly reliable quantitative diagnostic methods for pathologic changes such as fibrosis and fatty liver,also referred to as hepatic steatosis.Despite these advances,ultrasonography(US)still has several unrivaled advantages,such as excellent spatial resolution for microstructures,visualization of pathological changes in real time,portability,easy operability,and low cost.Thus,US is a highly useful imaging modality in clinical settings. In this study,we review the status and challenges of the US diagnosis of hepatic steatosis,by focusing on the B-mode image.
