Multifunctional Magnetic Resonance Imaging in Predicting Breast Lesions in Women Undergoing Mastectomy for Breast Cancer
Summary
RATIONALE: Diagnostic procedures, such as multifunctional magnetic resonance imaging, may help doctors learn the extent of disease and plan the best treatment.
PURPOSE: This clinical trial is studying how well multifunctional magnetic resonance imaging works in predicting breast lesions in women undergoing mastectomy for breast cancer.
Description
OBJECTIVES:
- To determine the accuracy of multifunctional magnetic resonance (MR) in detecting, localizing, and characterizing satellite lesions in relation to an index breast tumor in order to improve definition of clinical target volume after local excision.
OUTLINE: Patients receive an injection of gadolinium chelate and undergo multifunctional magnetic resonance (MR) imaging, including dynamic contrast-enhanced MR, hydrogen-MR spectroscopy, and diffusion-weighted MRI, of the ipsilateral breast within 4 weeks before surgery. Patients undergo a mastectomy as planned. The resected specimen is photographed, and a histopathological analysis is performed consisting of the size and grade (if pre-invasive or invasive disease) of each satellite lesion, classification of benign satellite lesions, dimensions of each lesion, distance from the edge of the index tumor to the center of each satellite lesion, and the distance from the center of the surface of the nipple to the center of each lesion.

Medical and Biotech [MESH] Definitions
Molecular Imaging
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Magnetic Resonance Spectroscopy
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).
Echo-planar Imaging
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.
Whole Body Imaging
The creation of a visual display of the inside of the entire body of a human or animal for the purposes of diagnostic evaluation. This is most commonly achieved by using MAGNETIC RESONANCE IMAGING; or POSITRON EMISSION TOMOGRAPHY.
Electron Spin Resonance Spectroscopy
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.
