In MRI of the kidneys, fast imaging techniques are essential because of respiratory motion of the kidneys [6]. When possible the scan should be performed within one breath-hold. The patient should get clear instructions on breath-hold technique. If the patient has difficulty with breath-holding, a short period of hyperventilation before breath-holding may be helpful. The scan should be performed during expiration because the kidney position is more constant in expiration than in inspiration. If the sequence is too long to perform in one breath-hold, respiratory triggering can be used [6]. Another technique of respiratory motion control is respiratory gating by use of a navigator pulse. In this technique the movement of the diaphragm is monitored by a very fast 1D MRI sequence. If breath-holding is not possible, signal averaging can be used, but the quality of the images will be limited. The use of a phased array body coil is preferable because of the improved signal-to-noise ratio. To prevent aliasing in coronal imaging, the patient’s arms should be raised above the head, or the arms may be supported by cushions, anterior to the coronal plane through the kidneys.
