The absence of enhancement of hypointense foci is usually an imaging description in the CT report, which refers to the presence of foci that are hypointense relative to the surrounding tissue and do not enhance significantly after injection of contrast. The significance of this is that it helps to rule out some diseases, such as stones and blood-rich tumors, etc. The absence of enhancement of hypointense foci does not clarify the nature of the foci alone. Clinically, the lack of enhancement of low-density foci can be caused by a variety of reasons, such as cystic lesions. If you need to know the nature of the lesion, you need to combine the location, size, morphology, border, rate of progression of the low-density foci and other imaging information with clinical manifestations and laboratory tests to make a comprehensive judgment. If there is no enhancement of the hypodense foci as described in the imaging report, it is recommended that the cause of the lesion be clarified under the guidance of a doctor and appropriate treatment be taken.
