MRI of adrenal glands: indications, preparation of the holding
MRI of adrenal glands is carried out for the diagnosis and monitoring of treatment. This precision study, which does not require special training. is paired endocrine glands located in the retroperitoneal space above the upper pole of the kidney. They produce gluco — and mineralocorticoids, are responsible for the regulation of glucose metabolism and salts, catecholamines – stress hormones and androgens.
Clinical manifestations of disease of the adrenal gland depend largely on the location of the lesion than to its nature. If the pathological lesion located in the cortical layer, suffers from carbohydrate and mineral metabolism, develops sexual dysfunction, in lesions of the medulla disrupted the cardiovascular and respiratory systems, changes in blood pressure.
- sudden weight gain with a characteristic fat deposition in the torso area or, alternatively, any unexplained weight loss;
- malignant hypertension;
- injuries in the lumbar;
- monitoring conducted after surgical treatment and dynamic observation with previously identified diseases.
Note that the symptoms of lesions of the adrenal glands are very diverse, there is little specific and usually unmarked, so pick an efficient and adequate diagnostic diagram only endocrinologist. It is not necessary to appoint a survey on their own is wasting time and money.
How is the study?
The patient is instructed to change into a gown or clothing, check for the presence of metallic impurities, after which it is placed on the sliding bed of the scanner. Before the start of the study it is moved inside the apparatus. The procedure lasts from 30 minutes to one hour and is performed under the supervision of a technician with whom the patient maintains contact with the integrated communications system. MRI of the adrenal glands painless, discomfort delivers being in a confined space and forced immobility.
Why you need an MRI with contrast?
The use of contrast allows to detect tumors of the adrenal glands and likely to shows their nature. With intravenous contrast enhancement is easy to differentiate tumor from diffuse hyperplasia of the adrenal gland, benign from malignant tumors, and to determine the localization of the pathological process.
MRI of the adrenal glands with the use of contrast agents improves the diagnostic value of the method, as it allows not only to detect pathology, but also to determine its nature.
How to prepare for the MRI?
If the MRI of the adrenal glands is planned a contrast medium for 5-6 hours before the examination you should not eat. Otherwise, no special preparation is required.
- clothing should not contain metallic inclusions, it may affect the research results or damage the unit;
- magnetic keys and plastic should not be in the field of the apparatus, in the process of preparing them better to remove;
- decorative cosmetics also better not to use some cosmetic products contain metal particles;
- dyes for tattoos contain metal particles, so after the MRI in this area may result in irritation.
MRI is contraindicated holders pacemakers and metal implants. In doubtful cases the preparation for an MRI includes verification of a patient’s body using a manual metal detector.
