For example, when there is pain in the inguinal region or abnormalities such as masses, the inguinal ultrasound can be used to check the presence of lesions, the size and extent of the lesions, and to make a preliminary determination of the nature of the lesions. If the inguinal region is rich in lymph nodes, you can check whether there is enlargement or other abnormalities in the lymph nodes and whether there is local thrombosis. Ultrasound of the inguinal region can also examine hip joints, gynecological and male varicose veins, etc. If ultrasound cannot confirm the diagnosis, further CT or MRI can be performed.
