What are the similarities between contrast needle examination and examination? How to choose?

Angiographic examination has certain similarities with conventional ultrasound examination and conventional X-ray examination, which can be selected according to the following advantages and disadvantages:

Conventional ultrasound examination: mainly for the abdominal cavity and pelvic parenchymal organs, as well as soft tissues such as thyroid and mammary glands, the advantage is that its examination speed is fast, can get the complete information of the affected part, the disadvantage is restricted by the experience of the examination.

Routine X-ray examination: mainly for the respiratory system, spine and bone and joint examination, as well as abdominal emergency screening, less used in the routine examination of abdominal organs, examination speed is fast, but the accuracy is poor.

Contrast-enhanced examination: Compared with conventional ultrasound examination and X-ray examination, contrast-enhanced examination can accurately determine the location of the lesion and the specific information of the lesion, but the examination requires a longer time and close cooperation of the patient. At the same time, there are more precautions before examination and the examination cost is high.

In conclusion, contrast examination is more accurate than conventional ultrasound examination and conventional X-ray examination, but the examination is time-consuming and there are many precautions before examination. It is necessary to grasp the indications, and the examination should be carried out in strict accordance with the guidance and requirements of doctors.
