Figure 5. A 36-year-old female with hypothyroidism presented with recurrent pericardial effusion. (a–c) Axial spin echo images show a moderate sized pericardial effusion (*). Note the resulting dilatation of the hepatic vein (a). The true extent of the pericardial reflections are well shown, extending further cephalad on the left than the right. Short axis gradient echo images in diastole (d) and in systole (e) showed no impairment of ventricular filling.
