There are various types of contrast imaging examinations, each with distinct methodologies. Common examples include:
1. **Gastrointestinal contrast study**: The patient fasts beforehand and then orally ingests barium sulfate contrast medium, followed by X-ray imaging.
2. **Coronary angiography**: Contrast medium is injected into the coronary arteries, followed by CT imaging.
3. **Hysterosalpingography (HSG)**: Contrast medium is introduced via the vagina to visualize the uterus and both fallopian tubes.
4. **Urography (intravenous pyelography, IVP)**: Contrast medium is administered intravenously, followed by contrast-enhanced imaging.
