MRI is not precise and clear enough for moving structures, such as the lungs, which move up and down with each breath. Therefore, MRI is rarely used for the diagnosis of lung disease. However, for the diagnosis of brain metastases MR accuracy is high and is the preferred means of performing brain metastasis examinations. In addition, but for the diagnosis of bone (spine) metastases MR accuracy is also high, and is necessary to perform the diagnosis of thoracic and lumbar vertebrae.
