Mild enhancement of liver ct is a description usually found on enhanced ct reports and is generally more commonly used to describe a space-occupying lesion in the liver. Mild enhancement on ct of the liver means that the lesion is slightly enhanced on good anatomical images. The more pronounced the enhancement, the more malignant the lesion, but this is not absolute. ct enhancement scanning is based on ordinary ct examination, the intravenous injection of contrast agent to increase the enhancement of imaging, can increase the contrast of the lesion and blood vessels and the surrounding tissues, more clearly show the scope and nature of the lesion, to provide a diagnostic basis for the qualitative diagnosis of the lesion. In the process of lesion development, according to the degree of enhancement, it generally manifests as no enhancement, mild enhancement, moderate enhancement, and obvious enhancement. Mild enhancement means that the enhancement value is less than 10 Hu; moderate enhancement means enhancement within the range of 10-30 Hu; obvious enhancement is greater than 30 Hu. The greater the enhancement value, the higher the degree of malignancy. Lesions with a low degree of enhancement have a poor blood supply and a higher likelihood of benign lesions, such as adenomas and tuberculosis balls. Lesions with high degree of enhancement have rich blood supply, which constantly provides nutrition for the lesion, and the possibility of malignancy is high, such as primary cancer, metastatic tumor, etc. Malignant tumors may also show mild enhancement or no enhancement. Therefore, to determine whether a lesion is benign or malignant, it is necessary to make a comprehensive evaluation based on the enhancement mode, the morphology of the lesion, the relationship between the lesion and the surrounding tissues, and other medical examination methods. Patients with mild enhancement of liver ct should go to the hospital in time for examination and treatment under the guidance of doctors.
