Iodine oil contrast is clinically referred to as tubal contrast. The contrast agent used in clinical practice is iodofol, which has long since been eliminated. Because iodine oil may be absorbed slowly in the body, iophorol is used to avoid this phenomenon. The main reason for having a tubal imaging is because clinically there is a suspicion of tubal obstruction. The tubal imaging can find out whether the tubes are obstructed, where the specific obstruction is and whether there is any abnormality in the development of the uterus. It is recommended that the appointment for tubal imaging should be made only after 3-7 days of menstrual cleansing, without intercourse, if the routine leucorrhoea, blood count, clotting time and electrocardiogram are normal after the outpatient examination. After the test, you can stay in the hospital for 1 hour for observation and leave the hospital only if you are not uncomfortable.
