心筋疾患は肥大型心筋症、拡張型心筋症などの原発性心筋症、アミロイドーシス、サルコイドーシスなどの二次性心筋症など多岐にわたり、マクロ的形態異常のみでは確診に至らない例が多い。しかし治療法の決定、予後推定には早期に診断することが求められている。非侵襲的診断のためには心エコー、CT、MRI、核医学検査等種々の画像診断モダリティが駆使されるが、最近、技術の進歩と病態理解の深化があいまって、どんどんと新しい解析手法や指標が生み出されつつある。しかし、どの疾患にどのタイミングでどのモダリティを使用して診断するのが効率的か、また予後推定にはどのモダリティが最適か、など臨床現場では迷うことも多いのではないだろうか。知識が不完全であれば、せっかくのモダリティが宝の持ち腐れともなりかねない。本セッションでは画像診断モダリティの最新の話題を取り上げ、その各種心筋疾患への応用を通じて、早期診断に資する種々モダリティの使い分け、将来展望についてディスカッションしたい。
Myocardial diseases are diverse, including primary cardiomyopathy such as hypertrophic cardiomyopathy and dilated cardiomyopathy, and secondary cardiomyopathy such as amyloidosis and sarcoidosis. Morphological abnormalities detected are not always helpful to diagnose cardiomyopathies. However, early diagnosis is required for determining treatments and predicting its prognosis. Various imaging modalities such as echocardiography, CT, MRI and nuclear imaging are used for noninvasive diagnosis, but recently, thanks to technological progresses and deeper understanding of pathological conditions, new analysis methods and parameters are being produced. However, in clinical practice, it may be difficult to determine which modality should be used at which timing for which disease to diagnose, and which modality should be optimal for prognostic prediction. Without true understandings, the modality can be useless. In this session, we would like to discuss the latest topics of diagnostic imaging modalities and discuss the future use of various modalities that contribute to early diagnosis through their application to various myocardial diseases.
