Development of MR Thermometry Strategies for Hyperthermia of Extremity and Breast Tumors
… tumor. This can be achieved noninvasively with MR thermometry. However, there are many challenges to performing MR thermometry in the breast, where hyperthermia of locally advanced breast cancer can provide a benefit. These include magnetic field system drift, fatty tissue, and breathing …

IMAGING SPECIFIC ABSORPTION RATE WITH MR THERMOMETRY USING PARAMAGNETIC LANTHANIDE COMPLEXES AND IN VIVO GABA MR SPECTROSCOPY IN MOVEMENT DISORDERS
Magnetic Resonance Imaging (MRI) is a popular imaging modality due to its ability to provide excellent soft tissue contrast without exposure to ionizing radiation. It can be used for temperature monitoring (thermometry) as well as for assessing the biochemistry in vivo (MRS). This dissertation …

Magnetic resonance spectroscopy: techniques and applications in thermometry and metabolite mapping
Magnetic Resonance Spectroscopy (MRS) is a useful tool for obtaining information about metabolite concentrations. Information that can be extrapolated from these concentrations may be absolute or relative in nature, depending on the availability of an internal reference. For example, MR Thermometry …

Verification of the <i>Ex Vivo</i> Thiel Embalmed Model for Liver Treatment with Magnetic Resonance-guided Focused Ultrasound (MRgFUS) before Clinical Practice
… Magnetic Resonance-guided Focused Ultrasound (MRgFUS) is a promising treatment option due to its non-invasive nature and due to the ability to perform MR Thermometry. Thermometry can provide real-time temperature feedback and temperature maps indicating the ablated area. Despite considerable …

Shear-wave imaging guidance for high-intensity focused ultrasound therapy
… for real-time HIFU temperature monitoring (MRI thermometry). In contrast, medical ultrasound guidance technique for HIFU still relies mostly on B-image mode and the hyperechoic contrast of the HIFU lesion. Additionally, commercial MR thermometry is relatively expensive, and is not truly 2D …

Temperature Mapping using Mid-Field Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality with excellent soft tissue contrast and sensitivity to tissue temperature. MRI use is growing in Canada with expectation that this is expected to continue in the medium term, with more wide adoption of MRI and in particular a …
