Abstract
Aim & Objective: To evaluate the normal testicular Apparent Diffusion Coefficient values in middle aged Indian population.
Methods and Materials: Fifty healthy volunteers were included in this study. Healthy volunteers among the patients with negative urine culture and no genitourinary disease as detected by urine analysis who were admitted to the urology department with various complaintswere taken into the study and finally confirmed by colour Doppler ultrasound. Diffusion Weighted Magnetic Resonance Imaging (DWI) was done for all participants and the data was used to generate ADC maps which were expressed as arithmetic means and SDs. A one-way analysis of variance with a post hoc Bonferroni test was used to analyze normally distributed continuous data. Mean ADC values were calculated for different age group under study.
Results: The mean ADC values of various age group were 1.062s/mm2, 1.055s/mm2,1.073s/mm2 and 1.075s/mm2 for age group of 20-24 years, 25-29 years, 30-34 years and 35-40 years respectively with no statistically significant difference between groups.
Conclusion: Based on the results of our study, it may serve as a standard reference value when studying the testicular anatomy and pathology on diffusion weighted imaging for various scrotal abnormalities
Key Words: Testicular ADC values, Apparent diffusion coefficient, Diffusion weighted imaging.
