Radiology
MRI uses strong magnetic fields to align atomic nuclei (usually hydrogen protons) within body tissues, then uses a radio signal to disturb the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline states. The radio signals are collected by small antennae, called coils, placed near the area of interest. An advantage of MRI is its ability to produce images in axial, coronal, sagittal and multiple oblique planes with equal ease. MRI scans give the best soft tissue contrast of all the imaging modalities. With advances in scanning speed and spatial resolution, and improvements in computer 3D algorithms and hardware, MRI has become an important tool in musculoskeletal radiology and neuroradiology.
Center for Biomedical Imaging
The Center for Biomedical Imaging houses a 3 tesla Philips MRI scanner for functional, structural, and spectroscopic studies of humans and animals. The Center for Biomedical Imaging provides researchers with access to the MRI as well as expertise in all modalities of MRI, not only for the Boston University Community, but also for researchers at other institutions. Currently, researchers at the Center for Biomedical Imaging are working on projects funded by the National Institute of Mental Health, National Institute of Neurological Disorders and Stroke, National Institute on Drug Abuse, Human Frontier Science Program (HFSP) and Nancy Lurie Marks Family Foundation.
