Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

NMR Spectrometers: Resolution and Error Correction

NMR Spectrometers: Resolution and Error Correction

When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Temperature Measurement Sites

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Background:

Proton Resonance Frequency Shift (PRFS) MR thermometry is crucial for clinical thermal treatments due to its speed and temperature sensitivity.
Motion artifacts, including image misregistration and susceptibility changes, introduce phase errors, compromising PRFS accuracy in moving organs.
Existing motion correction techniques for MR thermometry involve trade-offs in volume coverage, processing speed, and temperature precision.

Purpose of the Study:

To comprehensively review current advanced MRI techniques for motion-robust MR thermometry.
To recommend specific motion-robust MR thermometry strategies tailored to different thermal treatment applications.
To guide the selection of appropriate techniques and inspire future developments in clinical MR thermometry.

Main Methods:

Review of cutting-edge MRI techniques for motion-robust MR thermometry.
Analysis of trade-offs among volume coverage, processing time, and temperature accuracy for various methods.
Categorization of techniques based on application requirements (e.g., hyperthermia vs. ablation).

Main Results:

Identified inherent limitations and trade-offs in current motion correction technologies for MR thermometry.
Highlighted the differential needs for temporal resolution versus temperature accuracy in hyperthermia and ablation procedures.
Established a framework for selecting motion-robust MR thermometry based on clinical application.

Conclusions:

The choice of motion-robust MR thermometry strategy must align with the specific demands of the thermal treatment application.
Precise temperature measurement is paramount in hyperthermia, while rapid temperature rise monitoring in ablation requires high temporal resolution.
This review facilitates informed selection of MR thermometry techniques and promotes advancements in motion-robust volumetric MR thermometry for clinical practice.
