Magnetic resonance spectroscopy (MRS) allows the assessment of metabolic contents and biochemical information in vivo. It provides essential compositional information in the diagnosis and monitoring of central nervous system (CNS) diseases, especially brain tumors. Conventional MRS is usually confined to endogenous metabolites that may lack specificity for certain disease such as differentiating glioma from other tumor and non‐tumorous lesions. Therefore, exogenous MRS contrast agents (CAs) that may improve the sensitivity and specificity of MRS are highly desirable for its clinical use. In this work, a novel MRS CA, β‐alanine loaded hollow mesoporous silica nanospheres, with a high biosafety profile and characteristic MRS spectrum was synthesized and investigated. This new CA is further tested to realize the accurate functional MRS diagnosis of brain glioma with high sensitivity. The general approach of synthesizing disease specific CA for MRS may lead to a new era of molecular imaging.
