Which is more accurate, scanning CT or enhanced CT, is mainly evaluated according to the purpose of the examination. If the purpose of the examination is to determine the benign or malignant nature of the lesion, then the accuracy of enhanced CT is higher than that of plain CT, because enhanced CT will improve the density difference between the lesion and the neighboring tissues to reflect the lesion and improve the display rate of the lesion on the basis of plain CT by intravenous injection of contrast medium, so that the accuracy of enhanced CT is higher. If the purpose of the examination is for physical examination or preliminary examination, there is no need to carry out enhanced CT, ordinary CT can achieve a better detection effect. Scanning CT has a wider scope of application, which is suitable for the examination of many organs in the whole body, and does not need to be injected with any reagent, which is safer. If you need to undergo CT examination, it is recommended to consult a doctor in time, and the doctor will decide which CT examination method to choose according to the patient’s specific situation.
