Compared to other tests, MRI and CT provide high-resolution images. They are capable of multi-faceted tests, making them essential equipment in medical institutions. Many medical institutions have attempted to accurately identify and treat patient diseases by performing CT scansand MRI scans in conjunction. With the increase of aging population, the number of brain  CT examinations is also increasing. However, the baseline of brain CT examinations is different for each medical institution. In addition, CT and MRI examinations are applied differently for identical patients. The purpose of this study was to grasp the perception level of the baseline of brain CT and provide basic data. A structured questionnaire consisting of seven questions on the recognition level of brain CT examination baseline and six general questions was used. Selection criteria for study subjects were radiologists who had experience in brain CT  examinations in medical institutions. In the surveyed questionnaire, frequency analysis was performed to understand general characteristics of survey respondents and the criteria for brain  CT scout. In addition, Chi-square analysis as a crossover analysis was performed to determine the relationship between general characteristics and baseline brain CT. Statistical significance was considered when p value was less than 0.05. Recognition for the presence or absence of image difference according to CT baseline, age, and shift type was statistically significant (p < 0.11). Recognition for the difference in diagnostic range according to CT baseline, gender, age, CT room experience, and shift type was also statistically significant (p < 0.11). Recognition of CT baseline according to hospital size, CT room experience, shift type, and unification of medical institutions was also statistically significant (p < 0.01). In brain CT examination, it was found that examination baseline was significantly different depending on images and diagnostic ranges, unification of baselines of medical institutions, and baselines of MRI (p < 0.11). However, the currently used brain CT baseline is not determined. Thus, baseline is needed for brain MRI.
