A better understanding of the appearance of a biopsy needle as well as its interaction with various sequence parameters in MRI is beneficial for its application in interventional MRI. As an extension of previous researchers' contributions, we investigate the specific characteristics of MR image artifacts associated with the tip of a biopsy needle when it is approximately parallel to the main magnetic field. The origin of the needle tip artifact, which exhibits as a blooming ball, was studied using MRI techniques and numerical simulation using the finite element method (FEM). Satisfactory agreement between theory and experiment has been achieved. Results showed that the image artifacts associated with biopsy needle are present and dependent on imaging parameters, but the artifacts can be reduced if optimal imaging parameters were used. Images of actual human brain tumor biopsies performed using the same needle under MRI guidance and monitoring demonstrated this artifact.
