Sagittal 2D FLASH images obtained during IPDT of a hemangiopericytoma at the base of the tongue.
A, Initial entry angle of the 18-gauge needles, based on palpation of the tumor, had been misjudged, and the needles came to lie close behind the mandible (arrow). Needle artifact is large because of the almost-90° angle with the Z axis.
B, Imaging in the plane of the needle shafts allowed for easy correction of the entry angle and redirection of the needles toward the center of the tumor.
