Antonyms for Magnetic Resonance Spectroscopy could be words that describe the absence or lack of this technique. These words may include non-invasive, non-destructive, non-intrusive, non-contact, or non-ionizing. Alternatively, antonyms could also be words that describe the opposite technique, such as X-ray, computed tomography (CT), or positron emission tomography (PET). These imaging techniques use different principles, including radiation, to generate images of internal structures or functions. While Magnetic Resonance Spectroscopy is especially useful for investigating molecular structures and metabolic processes non-invasively, other techniques may play a more crucial role in different clinical or research settings.
