Realising the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.

Summary of "Realising the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer."

Computerised tomography based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image guided radiotherapy and adaptive radiotherapy models therefore have limited ability to improve clinical outcomes. The advent of magnetic resonance image guided radiotherapy solutions provides the opportunity to overcome these limitations with the potential to deliver online real time magnetic resonance imaging based plan adaptation on a daily basis, a true "plan of the day". This review describes the application of magnetic resonance image guided radiotherapy in two pelvic tumour sites likely to benefit from this approach.

Medical and Biotech [MESH] Definitions

A type of MAGNETIC RESONANCE IMAGING that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional MRI techniques. It is used in a variety of medical and scientific applications.

The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.

Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

Minimally invasive procedures guided with the aid of magnetic resonance imaging to visualize tissue structures.

A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
