The intervals between CT and enhanced MRI examinations are mainly the intervals between injections of contrast material, and there are no intervals stipulated for other times, which can be decided according to the condition.
CT is the use of X-rays to scan the patient’s body structure, which can be applied to the examination of any part of the body, and is suitable for infections, inflammation, occupying lesions, developmental malformations, fluid retention, etc. It does not require any special preparation, and the examination is fast and the results are also fast.
Enhanced nuclear magnetic resonance is based on scanning nuclear magnetic resonance, through intravenous injection of contrast agent, according to the difference in signal intensity before and after the injection of contrast agent, through the observation of different blood supply and different sources of lesions and normal tissues, so as to determine the type and nature of the lesion, which is widely used in the identification of the nature of tumors.
In daily clinical practice, CT or ultrasound examination is often done first, and enhanced MRI examination can be done according to the patient’s condition after problems are found, and the interval is mainly the time of contrast injection, and there is no special interval requirement for the rest.
