OBJECTIVE: The histological features of cortical tubers in patients with tuberous sclerosis (TS) were studied by the proton magnetic resonance spectroscopy (MRS).
MATERIAL AND METHODS: The subjects were 4 children, mean age of 10 years, with clear evidence of tubers on MRI and SPECT. Four age-matched control children served as control subjects. Spectra were acquired over the tuber using short TE.
RESULTS: The myoinositol/creatine ratios in the tubers of TS patients were significantly increased compared with those of the control subjects (P < 0.02). The NAA/creatine ratios in the tubers of patients were significantly decreased (P < 0.02).
CONCLUSIONS: The decrease of NAA/creatine ratios in the tubers of patients was considered to reflect a reduction of cranial neurons. The increase of myoinositol/creatine ratios in the tubers was thought to reflect an increase of glial cells. Proton MRS might play a role in estimation of histological changes in the neurological diseases.
