Abstract Objective： To compare the clinical value of conventional vision and small field thinsection target reconstruction CT technique in adrenal disorders. Methods： Between April 2018 and December 2021, 97 patients underwent both conventional scan and target reconstruction CT examinations at the People′s Hospital of Suzhou New District were included. Differences in image quality and diagnostic efficacy between conventional method and small field methods were analyzed according to signal noise ratio (SNR), contrast noise ratio (CNR) and image evaluation of image quality by two senior radiologists. Image quality indicators and subjective scores were statistically analyzed using the paired t-test and Wilcoxon tests. Image features and diagnostic coincidence rates were statistically analyzed using the Chi-square test. Results： SNR, CNR and image quality scores of small field method were significantly higher than those in conventional method (P<0.001). The coincidence rates of positioning and qualitative diagnosis of small field method were increased by 25.58% and 23.25% respectively compared with conventional method (P<0.05). There were statistically significant differences in adrenal status between the small field method and conventional method (P<0.05). Conclusion： Small field target reconstruction of CT images are conducive to the display of morphologic change and may be used to improve the diagnostic accuracy of adrenal disorders.
