Modern magnetic resonance imaging is one of the most informative methods of medical imaging. It allows a detailed assessment of the condition of internal organs, soft tissues, blood vessels, and nerve structures. In some clinical situations, a doctor may recommend performing an MRI with the use of a contrast agent. Such an examination helps to obtain clearer and more detailed images, which is important for the accurate diagnosis of various diseases.
At the Oxford Medical medical center, examinations are performed using a modern GE SIGNA Champion tomograph. The system is equipped with AI Recon DL artificial intelligence technologies, which improve image detail and ensure consistently high scanning quality. This makes it possible to obtain the most accurate examination results.
To undergo an MRI with contrast in Kyiv at the Oxford Medical clinic, schedule an appointment for a convenient time by phone or leave a request through the feedback form on the website.
During magnetic resonance imaging, in some cases a special contrast agent is used. It is administered intravenously before the start of the examination or during scanning. After administration, the agent enters the bloodstream and helps to more clearly display the structures of organs and tissues on tomographic images.
The use of contrast enhances the difference between different tissues. Thanks to this, during the examination it is possible to assess their structure in more detail, determine the boundaries of pathological changes more accurately, and increase the informativeness of the diagnosis.
Such an examination is especially useful in cases when it is necessary to clarify the nature of neoplasms, assess the condition of blood vessels, or study the features of tissue blood supply. For example, contrast may be used during vascular examinations, in particular during MR angiography.
Contrast enhancement makes it possible to obtain more detailed and informative images, which helps to more accurately assess changes in tissues and determine the further tactics of examination or treatment.
The main difference between these types of examination lies in the amount of information that can be obtained during scanning. Conventional magnetic resonance imaging allows a good assessment of the anatomical structure of organs and tissues and is often used for primary diagnosis.
If it is necessary to assess a certain area in more detail or clarify the nature of the detected changes, MRI with the use of contrast may be applied. In this case, the images become more informative for assessing the structure of tissues and the features of their blood supply.
Contrast enhancement is especially important in cases when it is necessary to study neoplasms in detail and assess their boundaries. This approach is used to clarify changes in various organs, in particular when during diagnosis an kidney tumor is detected, in the brain or in other areas.
Thus, standard MRI is usually used for a general assessment of the condition of organs and tissues, whereas contrast examination helps to obtain additional information in more complex clinical situations or when it is necessary to clarify the results of the previous examination.
MRI with the use of a contrast agent is prescribed when during the examination it is necessary
to assess the structure of tissues in more detail and clarify the nature of the detected changes.
Contrast enhancement increases the informativeness of diagnosis and helps to better visualize
pathological processes.
Most often, such an examination is recommended in the following cases:
suspicion of tumor formations or clarification of their structure;
assessment of the spread of inflammatory processes in tissues;
monitoring of tissue condition after treatment or surgical intervention;
detailed examination of changes in the brain or spinal cord.
Before performing an MRI with the use of contrast, the patient’s condition and possible limitations to the administration of the contrast agent are обязательно assessed. In most cases, such an examination is well tolerated, however, in certain situations contrast enhancement may be contraindicated.
The main contraindications include:
Before the examination, a blood test may be prescribed to assess kidney function in order to exclude contraindications.
Before conducting the examination, it is necessary to assess kidney function. For this purpose, a blood test for creatinine level with calculation of the glomerular filtration rate (GFR) is prescribed. It is usually performed in advance — within several days before the procedure. This helps determine whether the administration of the contrast agent is safe.
On the day of the examination, it is recommended to refrain from eating for 3–4 hours before the procedure if contrast administration is planned. Water may be consumed as usual if the doctor has not given other recommendations.
Before the start of scanning, it is important to inform the specialist about:
Immediately before the procedure, it is necessary to remove all metal objects and accessories. Following these recommendations helps conduct the examination as safely as possible and obtain accurate MRI results with contrast enhancement.
Before the examination begins, the patient is positioned on the movable table of the tomograph. The head or another area of the body is fixed using special rollers or fasteners to ensure immobility during scanning.
First, a series of images is taken without the contrast agent. After that, the contrast drug is administered intravenously and the scanning is continued. This makes it possible to obtain additional images with increased informativeness.
MRI with contrast for children is performed taking into account the age and psychological comfort of the child. During the examination, parents may be nearby to help the child calmly undergo the procedure and remain still.
The duration of MRI with contrast enhancement usually is up to 30–40 minutes depending on the area of examination and the scope of scanning. The examination is painless, however, it is important to remain still until it is completed.
MRI with the use of contrast is usually well tolerated. Modern contrast agents have a high safety profile, therefore adverse reactions occur rarely.
In isolated cases, after the examination the following may be observed:
Allergic reactions occur rarely, but may manifest as a rash, itching, or redness of the skin.
To minimize risks, before the procedure the patient’s health condition is assessed, in particular kidney function. After MRI with contrast enhancement, it is usually not necessary to follow special restrictions, however, consuming a sufficient amount of fluid may be recommended.
In most cases, the procedure проходит without complications and does not affect well-being.
Prices for MRI with contrast in Kyiv at the «Oxford Medical» medical center depend on the examination area. The cost of such an examination is somewhat higher compared to standard tomography, since it involves the administration of a contrast agent and the performance of additional series of images. You can ознакомиться with the prices here in advance.

MRI with contrast enhancement usually takes from 20 to 40 minutes depending on the area of examination and the scope of scanning. First, a series of images is taken without contrast, after which the agent is administered and the examination is continued. Additional series of images require time, so the procedure is slightly longer than a standard MRI without contrast.
The choice depends on the clinical task. A regular MRI is suitable for the primary assessment of the condition of organs and tissues. An examination with contrast is prescribed when it is necessary to study the structure of tissues in more detail, clarify the nature of changes, or assess blood supply. The final decision is made by the doctor taking into account the symptoms and the purpose of the examination.
In most cases, after an MRI with contrast there are no strict restrictions. It is recommended to drink a sufficient amount of water during the day and avoid excessive physical exertion. If unusual symptoms appear, for example a rash or worsening of well-being, it is worth consulting a doctor.
The frequency of MRI with contrast is determined individually depending on the clinical situation. Since the method does not use ionizing radiation, it can be repeated when necessary. At the same time, it is important to take into account the indications for contrast enhancement and the general condition of the patient, in particular kidney function.
Smoking is not a direct contraindication to performing an MRI with contrast, however, before the examination it is advisable to refrain from it for at least several hours. This helps avoid possible discomfort and improve general well-being during the procedure, especially if a temporary restriction of food has been recommended.
After an MRI with contrast, it is recommended to refrain from consuming alcohol for at least 24 hours. This is related to the fact that the body needs time to adapt after the administration of the agent.
MRI with contrast is considered a safe diagnostic method. Contrast agents undergo thorough testing and are well tolerated by most patients. Before the examination, possible contraindications are taken into account, which allows minimizing risks and conducting the examination as safely as possible.
The contrast agent is administered intravenously, usually into a vein in the arm. The procedure takes several minutes and is performed by medical staff before or during the examination. After administration, the agent quickly enters the bloodstream and begins to act.
The contrast agent is gradually eliminated from the body within 24–48 hours. The duration may depend on individual characteristics and kidney function. To accelerate the process, it is recommended to drink a sufficient amount of water after the examination, if there are no restrictions from the doctor.
