RESUMEN
Cardiac involvement in amyloidosis has a relatively poor prognosis, and early diagnosis and treatment is very important to the prognosis of such involved patients. "One stop type" cardiac examination can be carried out by the cardiac magnetic resonance imaging (CMRI) and the evaluation of cardiac morphology and function can be complete. "One stop type" CMRI may show the thickness of myocardium in left ventricle, cardiac diastolic dysfunction, sub-endocardial enhancement (patch, diffuse and transmural types), rising of T1 value, too fast clarifying rate of contrast agent in blood pool, pericardial and/or pleural cavity effusion, that may help to elevate the efficiency of diagnosis. The CMRI presents myocardial tissue characteristics quite well, that may help for early diagnosis of myocardial amyloidosis, and clearly demonstrate the situation of heart involvement; to follow-up patients with repeat CMRI examinations can monitor drug therapeutic effect, direct and regulate treatment, judge prognosis, etc. so that CMRI possesses very high clinical application value.
