During an MRI scan, the radiofrequency field from the scanner's transmit coil, but also the
switched gradient fields, induce currents in any conductive object in the bore. This makes …

Magnetic resonance imaging and spectroscopy (MRI/MRS) at 7T represents an exciting
advance in MR technology, with intriguing possibilities to enhance image spatial, spectral …

Purpose To investigate how the simultaneous exposure to gradient and RF fields affects the
temperature rise in patients with a metallic hip prosthesis during an MRI session. Methods In …

This work focuses on the in silico evaluation of the energy deposed by MRI switched
gradient fields in bulk metallic implants and the consequent temperature increase in the …

Purpose To theoretically investigate the feasibility of a novel procedure for testing the MRI
gradient‐induced heating of medical devices and translating the results into clinical practice …

To protect implant carriers in MRI from excessive radiofrequency (RF) heating it has
previously been suggested to assess that hazard via sensors on the implant. Other work …

Magnetic resonance imaging (MRI) systems must undergo quantitative evaluation through
daily and periodic performance assessments. In general, the reference or standard …

Purpose To evaluate radiofrequency (RF) induced tissue heating around aneurysm clips
during a 7T head MR examination and to determine the decoupling distance between …

Purpose To investigate inter‐subject variability of B1+, SAR and temperature rise in a
database of human models using a local transmit array for 7 T cardiac imaging. Methods …

The possible heating of metallic devices implanted in the patient's body is a source of
concern in MRI, discussed in many papers and standards. 1-15 Two fields may produce …
