MR spectroscopy was performed in three patients with brain abscesses. In two patients, MR spectroscopy revealed end-products of bacterial breakdown (acetate, succinate, amino acids, lactate) in the abscess cysts. In one of these, the spectrum was reversed to a single lactate peak after treatment. In the third patient, MR spectroscopy was performed only after treatment and showed a single nonspecific lactate peak. MR spectroscopy is a potential tool for noninvasive diagnosis of brain abscess and might be useful for evaluating changes after treatment.
对三名脑脓肿患者进行了磁共振波谱分析。在两名患者中，磁共振波谱分析显示脓肿囊肿中有细菌分解的终产物（乙酸盐、琥珀酸盐、氨基酸、乳酸盐）。其中一名患者在治疗后频谱反转成单一的乳酸盐峰。第三名患者仅在治疗后进行了磁共振波谱分析，显示出单一的非特异性乳酸盐峰。磁共振波谱分析是脑脓肿无创诊断的一种潜在工具，可能有助于评估治疗后的变化。
