Cine segmented steady-state free-precession MRI of the heart in 14-years-old boy diagnosed with arterial hypertension. Contours of epicardial adipose tissue (EAT) are outlined by hand on end diastolic short-axis image. The EAT volume (EATV) is 14.89 cm3.

The MR imaging of the common right carotid artery. T1-weighted dark blood fast-spin echo pulse sequence demonstrated adequate soft tissue contrast. The intimamedia thickness of the vessel wall is outlined.

Receiver operating characteristic curve (ROC) and area under the curve (AUC) values were used to assess the performance of potential predictors for hypertension.
cIMT = carotid intima-media thickness; EATV = epicardial adipose tissue volume
