Real-time MRI

Caption: This is a real-time MRI of the heart with a measurement time of 33 milliseconds per image and 30 images per second. The spatial resolution is 1.5 millimeters in the image plane (section thickness 8 millimeters). The eight successive images show the movement of the heart muscle of a healthy subject for a period of 0.264 seconds during a single heartbeat. The images range from the systolic phase (arrow, top left: contraction of the heart muscle) to the diastolic phase (arrow, bottom right: relaxation and expansion). The bright signal in the heart chambers is the blood.
