dc.description.abstractIt is well known that the relaxation rates (1/T-1 and 1/T-2) in H2O/D2O mixtures are smaller than those in H2O alone. The results of this have not been examined in the presence of a low rate of cysts or abscess contents in D2O. One purpose of this study was to determine the shortening of the relaxation rate distribution interval (SRDI) for D2O containing cysts or abscess contents. Another goal is to investigate the differentiation of cysts from abscesses with T-1 and T-2 measurements. The ultimate objective is the possibility of a new MRI contrast mechanism for dental lesions. Nineteen odontogenic jaw cysts and 12 jaw abscesses were collected from patients. A mixture was prepared by adding 0.06 mL cyst or abscess content to 0.94 mL D2O. The experiments were carried out with a nuclear magnetic resonance spectrometer operating at 400 MHz. The mean 1/T-2 of the abscesses was significantly different from that of the cysts (P < 0.005), but the mean 1/T-1 of the non-haemorrhagic cysts was not different from that of the abscesses (P = 0.626). The interval shortening ratios (SRDIs) of 1/T-1 and 1/T-2 for the cystic mixture were 16.36 and 4.22, respectively. The ratios were 8.39 and 2.68, respectively, for the mixture containing abscess contents. In conclusion, the relaxation rate reduction of the mixture results in a shortening of the distribution intervals, which leads to the separation of cysts from abscesses. In addition, the high interval shortening ratios indicate that the results of this study can provide a basis for studies on a new MR contrast mechanism for jaw lesions.en_US
