Doppler examination is a non-invasive diagnostic test that allows us to assess the condition of our arteries and veins, and most importantly – to detect their obstruction, which may be caused by atherosclerotic lesions. It is also used to detect life-threatening aneurysms.
Using Doppler examination, we are able to evaluate the degree of efficiency of veins and arteries, as well as identify with great accuracy the places where the disease changes occurred, such as venous blockages or aneurysms. By narrowing the veins or arteries, the patient’s life can be put at real risk because it can cause such dangerous conditions as stroke, heart attack or pulmonary thromboembolism. In this case, it is essential to detect abnormalities in the blood flow and to take remedial measures in the right time.
The factor that alerts us to go for Doppler examination is the fact that we suspect atherosclerotic changes in arteries or other blood vessels, varicose veins, suspicion of aneurysm or other conditions indicating abnormal blood flow in the veins and arteries. Doppler examination is also recommended in the case of neoplastic tumors in which blood flow in lymph nodes is evaluated, liver tumors are differentiated and their degree of malignancy is assessed.
Doppler ultrasound can also be used to examine blood flow, as well as changes in the carotid and subclavian arteries, heart, abdominal organs, genitals and upper and lower extremities. Doppler examination allows to detect stenosis of arteries, which may be caused by atherosclerosis, venous thrombosis or other changes in blood vessels located in the abdominal cavity, neck and limbs.
Doppler examination involves the use of the so-called “Doppler effect” for diagnostic purposes. The head of the Doppler apparatus applied to the patient’s body sends out an ultrasound wave, which penetrates the body. This wave is reflected by blood molecules that are moving and returning to the head. At this point, the signal is sent to an ultrasound device that records changes in the frequency of the sound wave reflected from the flowing blood. The test result is presented as an image on the monitor (the places where the blood flow is lower or ceases at all are marked on the monitor).
This test is non-invasive and painless. In case of Doppler ultrasound of renal arteries, it is necessary to have the test performed while being fasting. During the procedure, the patient removes the clothes from the places where the head of the Doppler apparatus will be placed and then lies down on the couch. The doctor applies the camera head to the skin lubricated with a special gel. Reflected ultrasound waves are then displayed on a monitor, which allows for real-time assessment of blood flow and the condition of blood vessels.The result of the Doppler test is obtained immediately after its completion in the form of a graph or a coloured drawing described by the doctor. It may be the basis for referring the patient to a procedure or for pharmacological treatment. The Doppler device measures the blood flow through the vessels and the artery section, which determines venous efficiency. They are also used to assess blood supply to certain internal organs and to detect cancer lesions.
MediSpace specialists, through a thorough examination process, are able to determine what kind of ailment is to be dealt with, through an individual approach they propose the most effective way to combat it. The experience, which is supported by many trainings and courses, gives us confidence when making decisions about actions.
