摘要：MSCT is one of the modalities to diagnose kidney function. Urinary tract examination or by using tracking reconstruction without using positive contrast media is able to produce urinary tract images and use tracking able to identify urinary tract images with urolithiasis. The need for an appropriate ASIR setting value in the MSCT plane parameters, To prove differences in image quality and identify which ASIR is best for MSCT too knowing the optimal image between using tracking and CT Urography examination using contrast. This experimental study with the PostTest Only Group Design study design, the number of samples used was 5 groups. The results of MSCT image showed that there was a significant difference in the value of < 0,001 (p <0.05) with the mean value for each ASIR as follows 20 mean value 3.40, ASIR 40 mean value 7.90, ASIR 60 mean value 12.70, ASIR 80 mean value 18.00, ASIR 100 mean value 23.00. The results of the MSCT urinary tract analysis after the ASIR test showed that there were significant differences between ASIR. Conclusion optimal image results using tracking by The mean value is ASIR 100 the rank of 23.00 and CT Urography using positive contrast media of 8.00.
