“…In clinical practice, dielectric properties can be obtained individually for every patient using electric property tomography, which uses magnetic resonance imaging (MRI) scanner [37,38]. MRI, along with Electric Impedance Tomography and Microwave Imaging, can be employed for non-invasive temperature monitoring during the HT, improving the overall treatment quality [39][40][41][42].…”

During a microwave hyperthermia oncology treatment, the target region temperature is elevated to the temperatures of 40–44 °C, which improves the therapeutic effect of a standard radiotherapy and/or chemotherapy treatments. Amplitudes and phases of antenna input signals in the phased array setup surrounding the 3D patient model are optimised with respect to maximise the energy deposition in the target region. In this study, we successfully integrated an automatic artificial intelligence segmentation routine, used for patient-specific 3D model generation, into the hyperthermia treatment planning process. This allows us to apply more realistic patient 3D model for the online hyperthermia guidance including detailed retrospective analyses of the overall treatment quality, possibly leading to a widespread clinical use of the hyperthermia treatment planning.

“…[10] Furthermore, Feddersen et al tested different multi-echo gradient echo pulse sequences for PRF MR thermometry. [11] To achieve an optimal temperature mapping it is necessary to detect minimal changes in the tissue/organs. Hekmatyar et al proposed that in the future it will be necessary to achieve a temperature sensitivity of around 0.5 K. [4b] External thermometers have an accuracy of around 0.1 K but the disadvantage of such thermometers is their invasive introduction of the thermometers and the limited measuring region.…”

In the past few decades, magnetic resonance spectroscopy (MRS) and MR imaging (MRI) have developed into a powerful non‐invasive tool for medical diagnostic and therapy. Especially 19F MR shows promising potential because of the properties of the fluorine atom and the negligible background signals in the MR spectra. The detection of temperature in a living organism is quite difficult, and usually external thermometers or fibers are used. Temperature determination via MRS needs temperature‐sensitive contrast agents. This article reports first results of solvent and structural influences on the temperature sensitivity of 19F NMR signals of chosen molecules. By using this chemical shift sensitivity, a local temperature can be determined with a high precision. Based on this preliminary study, we synthesized five metal complexes and compared the results of all variable temperature measurements. It is shown that the highest 19F MR signal temperature dependence is detectable for a fluorine nucleus in a Tm3+‐complex.
