PDFAbstract
Objective To explore the value of conventional MR combined with ADCmin in diagnosis and differential diagnosis of parotid lymphocystis disease. Methode The MRI characteristics of 21 patients (103 lesion) of parotid lymphadenopathy and 14 patients (multiple, 57 lesion) of non-lymphadenopathy with pathologically confirmed were analyzed retrospectively. In addition , the minimum ADC value of lesions were measured and compared. Results Incidence of homogeneous signal in parotid lymphadenopathy group(100%) were obviously higher than in non-lymphadenopathy group (21%, P ＜0.05). Incidence of cervical and submandibular lymph nodes enlargement in parotid lymphadenopathy group(100%) were obviously higher than in non-lymphadenopathy group(14%,P＜0.05). The minimum ADC Value of lymphadenopathy was lower than non-lymphadenopathy, respectively (0.62±0.12)×10-3mm2 /s, (1.07±0.15)×10-3mm2 / s, the difference was statistically significant(P＜0.05). Conclusion Conventional MR combined with minimum ADC value avail the diagnosis and differential diagnosis of parotid lymphocystis disease.
