Magnetic Resonance Spectroscopy (MRS): basic principles and applications in focal brain lesions.
Pak J Neurological Sci Jan ;2(1):42-6.

MR spectroscopy enables imaging at the molecular level, providing information about brain tissue that was previously available on biopsies only. Its availability on routine clinical MRI systems has given MRS studies wider clinical applicability, thus helping in improved patient care. It is becoming a part of the practice of neuroradiology, enabling the radiologist to start differentiating between benign and malignant processes. The technology, however, is not infall ible and should be considered an adjunct to anatomical imaging rather than a replacement for histopathological evaluation. This is a review article.
