Where and how to check the blood vessels? MRI of blood vessels
When it comes to vascular diseases, many imply such ailments as atherosclerosis - the destruction of the walls, and varicose enlargement - a change in the diameter of the venous bed. However, these are only the most common ailments. Vessels permeate the entire human body, passing through virtually all tissues. Therefore, there are many more diseases. These include hemorrhoids, varicose veins of the small pelvis, lymphostasis of the limbs, tortuosity of the arteries, thromboses, phlebitis and so on. In order to avoid the development of any disease, it is necessary to regularly undergo a survey. Unfortunately, not everyone knows how to check blood vessels.
Who should check the vessels of the head
So, how to check the blood vessels? First of all it is necessary to visit a specialist of a narrow profile. At the same time, many, having felt an indisposition, do not know who should be treated to the problem that has arisen. In small settlements there is always a therapist or a paramedic. Medical workers should refer the patient to the right specialist.
If you live in a large city, then in the clinic there must necessarily be a neurologist or, in another way, a neuropathologist. This doctor can help with various hemorrhages in the brain and injuries, with the development of osteochondrosis, as well as in violation of coordination of movement and sleep. In other words, this specialist is able to help in the presence of vascular diseases of the nervous system.
To clarify the diagnosis, the neurologist may refer the patient to an additional examination of the cerebral arteries. After all, if there is a disturbance of blood circulation, a person experiences a general malaise, which is manifested by frequent headaches, increasing irritability and dizziness.
Where to check the vessels of the legs and the heart
Receptacles on the legs can be checked with a doctor, such as an angiosurgeon, or an angiologist. He is a specialist in vascular surgery. Thanks to modern methods of diagnosis, a doctor can help a person in a timely manner in the development of diseases such as a violation of potency, thrombosis, thrombophlebitis, trophic ulcer, kidney failure, stroke, and so on. In the competence of this specialist treatment of all possible lesions of arteries, veins and lymphatic vessels. This explains the diverse range of activities of the angiologist. If desired, the condition of the veins can be checked with a phlebologist.
Where and how to check the blood vessels of the heart? In this case, it is worth turning to a cardiologist. However, referring to a specialist, the patient must take into account that in some cases, a clear boundary and divide the diseases of the heart and vascular ailments is impossible. For example, hypertension. This disease adversely affects the cardiovascular system as a whole. Phlebitis and atherosclerosis are capable of damaging the veins and arteries of the whole organism. In addition, myocarditis and rheumatism are primordial heart diseases. Therefore, in order to establish the correct diagnosis, a thorough examination is required.
When checking the vessels of the brain and neck
How to check the vessels of the brain and neck? First of all it is worth to visit a specialist of a narrow profile. The doctor should prescribe a thorough examination. Check of vessels of a brain and a neck is actual at:
- VSD - vegetative-vascular dystonia.
- Ischemia of the brain.
- Circulatory disturbance.
Also a check of the vessels of the brain and neck is required in cases when the patient is disturbed by frequent attacks of headache and dizziness. This may indicate a serious illness.
MRI - a modern diagnostic method for
How can I check my brain vessels and get a full assessment of the system? In this case, the doctor can prescribe an MRI( magnetic resonance imaging).This is one of the modern diagnostic methods. Such a study allows obtaining all the necessary data on the pathological and structural changes in the vascular bed of brain tissues. In addition, MRI gives a complete assessment of the processes that occur at the time of the examination. This method allows you to study the condition of the walls of the vessels, as well as to check whether there are clusters of plaques on them.
Because you can check the cerebral vessels only with the help of a special device, you should take into account its errors. Some devices simply can not see minor changes. These include the device MRI, whose magnetic field is from 0.3 to 0.4 TL.This device has a low resolution. It is better to carry out MRI of vessels using an aggregate with a magnetic field of 1-1.5 T.The device allows you to notice any changes in the tissues.
In some cases, vascular MRI is performed in conjunction with the contrast method. In this case, the patient's blood is colored with special substances. This allows for a more detailed examination. Thanks to this method, it is possible to detect not only pathological changes, but also thrombus and plaques.
REG - rheoencephalography
Since there are not many people who can check the vessels of the brain and neck through MRI, there are other methods of examination. The main disadvantage of magnetic resonance imaging is high cost. In addition, not every clinic has special equipment. And how to check the vessels without the necessary apparatus? The second method of examination is a rheoencephalography. It is used much more often. There is another name for this procedure - cerebral rheography.
How is the
conducted? The examination takes place in the clinic. To diagnose vascular diseases, a device such as a rheograph is used. This unit is essentially a current source equipped with metal plate electrodes, which are fixed on the scalp. Mounted device with rubber bands. Before the procedure, the skin should be degreased with alcohol. The plates are also treated with a contact paste.
How can I check the vessels with a rheograph? It's simple. After the electrodes are fixed, a weak current is passed through them. At this moment, the recording of the state of all vessels begins. In this case, the electrodes can be fixed on the surface of the entire head or in a certain area.
The information on the state of the vessels is obtained by observing the way the processes of the electrical conductivity of the body and the covers proceed. The difference between the indicators gives the effect of pulsation. This allows us to obtain accurate data on the activity of the venous and arterial systems.
The examination of the vessels of the neck and brain can be carried out in another way. In this case, we are talking about a method such as duplex scanning. Such a study is relevant in the presence of diseases of the cervical vessels - brachiocephalic arteries.
So, how do you test the vessels with Doppler? This is a completely painless procedure, which is ultrasound. Ultrasound examination allows to evaluate the state of the vessels of the whole body. If the patient suffers from high blood pressure, then the experts conduct a check on the kidneys. Narrowing of the vessels located in these organs can cause a severe form of hypertension.
How doppler is performed
The simplicity of this survey method attracts many. After all, the procedure does not require preparation. The patient should take a horizontal position during the examination. The result is instantly displayed on the monitor. The doctor receives the data thanks to special sensors.
The main drawback of dopplerography is that not every medical institution has special equipment. In addition, the accuracy of the results depends on the correct operation of the device and the experience of the doctor.
Where and how to check blood vessels for blood clots? In this case ultrasonography will help. At such inspection the patient should be in a horizontal position. In this case, the head should be thrown back and turned in the opposite direction from the one that must be inspected. The sensors are then directed up the neck, under the jaw, and then behind the ear. Ultrasonography allows you to carefully consider the condition of not only the carotid artery, but also the vertebral column. For this, the patient should lie on his side. The given doctor receives thanks to the ultrasound scanner.
Indications for use
Duplex scanning of the neck allows you to get a lot of valuable information. Such an investigation is relevant for:
- loss of consciousness, gait unsteadiness and dizziness;
- pulsating formations in the neck region;
- memory impairment and vision.
How the heart vessels are examined
It is possible to check the heart function and the condition of the patient's vessels without entering. To do this, you can tap, measure pressure and pulse, listen to the heart rate, and so on. A comprehensive examination of the state of the vessels and heart consists of:
- checking the elasticity of the vessels;
- ECG - electrocardiograms;
- study of blood flow in the extremities( rheovasography).
As for the full survey, it includes other methods.
How can I check the blood vessels of the whole body if dopplerography does not work? In this case, a CT scan is performed. This method first appeared in 1972.The technology gradually changed and improved. The tomograph is a table surrounded by an annular shell and connected to the scanner. This device is quite simple to use. The patient is placed on the table inside the ring, which gradually rotates and removes the necessary area.
It should be noted that computed tomography allows you to explore not only the coronary vessels, but also the vessels of the extremities, abdominal, thoracic and pelvic parts. This greatly facilitates the diagnosis of many diseases. Such a survey allows you to determine the degree of narrowing of the vessels in the heart, while not performing intracardiac manipulations.
Computer tomography is performed in a conventional clinic. To improve the image quality, enter a contrast agent. Often, iodine is used for this purpose. When examining the heart, the tomograph can produce a three-dimensional picture with colored vessels. This allows you to identify any deformation of the arteries and veins, as well as determine the state of the aorta and exclude the presence of tumors.
Varicose veins: diagnosis
How to check the vessels on the legs with varicose veins? This question is asked by those who regularly feel the heaviness in the lower extremities after a working day. Often, patients with this disease complain of swelling and a sense of fatigue. In addition, many venous patterns become more pronounced. In this case, it is necessary to consult an angiologist or phlebologist.
Diagnosis of the disease begins, as a rule, with a visual inspection of the skin. To study the condition of tissues, veins and their valves in more detail, it is necessary to conduct additional studies. In this case, the doctor can prescribe the following examination:
- Ultrasound scanning.
- Marching test Delba-Partesa and other samples.
- Radiography: venography, phlebography.
- Functional-dynamic phlebomanometry.
The latter method allows obtaining more accurate data, since in the process of diagnosis, venous pressure is measured during physical exertion. This indicator in the vertical position at rest can not exceed hydrostatic. However, ultrasound examination is necessary to detect damaged valves.
Now you know how to test the vessels of the whole body. At the moment there are many ways to diagnose all sorts of diseases. Special equipment allows you to check the vessels not only of the brain, but also of the heart, abdominal and hip part, extremities and neck. Such a survey allows you to detect the disease in time and prevent the development of serious complications.
