Magnetic Resonance Spectroscopy (MRS): is a relatively new technology, used on a limited basis for the biochemical evaluation of brain tumors, neurological diseases, certain inflammatory and ischemic diseases, disorders of metabolism and epilepsy.  MRS can also be used to assess chemical

composition of the vertebral body.  Through the use of a strong magnetic field, the chemical composition and metabolic activity of tissue is analyzed and

recorded.  Spinal spectroscopy will have greater clinical application as the

technology and protocol technology improves.  MRS is like an MR biopsy.  MRS can be used for the evaluation of primary brain tumors, infections such as AIDS, demyelinating disorders, sclerosis, epilepsy, and stroke.

Magnetic Resonance Angiography (MRA): MR angiography (MRA) is an MRI study of the blood vessels.  It utilizes MR technology to detect, diagnose and aid the treatment of heart disorders, stroke and blood vessel diseases.  MRA provides detailed images of blood vessels without using contrast, although there are special forms of contrast usually given to make the MR images even clearer. The procedure is painless, and the magnetic field is not known to cause tissue damage of any kind.  It is a method that produces extremely detailed pictures of blood flow without the need for X-rays.  The electromagnetic energy that is released when exposing a patient to radio waves in a strong magnetic field is measured and analyzed by a computer, which forms two- or three-dimensional images that may be viewed on a TV monitor. 

DynaWell^® Lumbar-Spine MRI Compression Device: Lumbar spine scanning requires more planning than conventional scans of the rest of the body.  The positioning of the patient and selection of an appropriate technique to fit the clinical indications is essential.  The DynaWell^® L-Spine is a helpful diagnostic tool for CT or MRI scanning.  The DynaWell^® L-Spine system offers a comfortable, easy-to-use diagnostic technique that enhances the data acquired by the scanner.  Some problems that would ordinarily remain undetected when the patient's spine is relaxed may become visible because of the axial compression generated by the DynaWell device. 

During an ordinary CT or MRI scan, the patient is asked to lie down on a flat table in a “psoas relaxedâ€? position which places the spine in an unloaded position, thus potentially rendering images that are not truly function or mimic the typical gravity position of the patient (a potentially painful position).  However, with DynaWell L-Spine vest in place and the patient's feet placed against the footplate of the compression device a desired and measured load (up to 50% of body weight) can be applied to the patient’s spine, thus compressing the spinal column in a way that is similar to that of upright posture.  The subsequent scan provides enhanced cross-sectional and longitudinal images of the patient's back that often reveal problems not otherwise visible during a traditional CT or MRI exam.  The DynaWell L-Spine may allow for earlier and more valid diagnosis in the Axial Compression in Extension ("ACE") position.
