A study to compare the low-dose and standard-dose computed tomography for diagnosis of urolithiasis

Abstract

Background: CT scan is very high sensitive in the diagnosis of calculi. However, it also has its own disadvantage and most important is its radiation. One of the most prominent radiations involved in the medical field is through the CT scan. Hence, it is better to use low dose CT as it emits less radiation than standard radiation. Objectives: The current study was undertaken to observe the effectiveness of low dose CT by comparing with standard CT. Methods: The present study involved 40 patients within the age group of 40 to 60 years of age who were suspected cases of urolithiasis and referred to radiology department for CT scan. Both males (n=18) and females (n=22) were included in the study. Results: There was no significant difference between low dose and standard dose scoring. This clearly indicates that low dose CT is as efficient as standard dose and it can be used for multiple purposes. Conclusion: The study observed no significant difference between the sensitivity levels among standard dose and low dose CT. The study recommends further detailed and multi centric studies to recommend use of low dose rather standard dose for benefit of general population.
