Non-contrast T1-mapping detects acute myocardial edema with high diagnostic accuracy: a comparison to T2-weighted cardiovascular magnetic resonance.
Dr. Ferreira and cols investigated 21 controls (55 +/- 13 years) and 21 patients (61 +/- 10
years) with Takotsubo cardiomyopathy or acute regional myocardial edema
without infarction. They hypothesized that
T1-mapping would have a higher diagnostic performance in detecting acute
edema than dark-blood and bright-blood T2w-CMR. Their conclusion was that non-contrast T1-mapping using ShMOLLI is a
novel method for objectively detecting myocardial edema with a high
diagnostic performance. T1-mapping may serve as a complementary
technique to T2-weighted imaging for assessing myocardial edema in
ischemic and non-ischemic heart disease, such as quantifying
area-at-risk and diagnosing myocarditis.
