Thoracic aortic resonance imaging is an imaging medium that is increasingly being widely applied thanks to its outstanding advantages such as clear, detailed, radiation-free imaging. However, due to the long duration of the operation, aortic MRI scans are not suitable for urgent diseases and the role of aortic an aortic anathesiography cannot be replaced with CT Scan.

1. The role of thoracic aortic mri?

The thoracic aortic is the first of the aortic and is divided into 3 segments: the aortic up, the aortic supply and the aortic down. The thoracic aortic artery comes from the aortic valve, located off the left side of the middle line corresponding to the 3rd rib interval. The thoracic aortic is the large artery of the body, which is responsible for the blood supply to the thoracic cage, the upper genus, and the head area of the neck.

Chest aortic resonance imaging or chest aortic MRI is a modern, non-invasive, X-ray-free and highly safe imaging medium. The role of chest aortic MRI scans is evident in monitoring aortic diseases such as aortic dissection, aneurysms, aortic stenosis due to atherosclerosis or spasms. The means of evaluating the structure and function of the thoracic aortic that are being commonly used are Doppler ultrasound. However, aortic doppler ultrasound has many limitations due to its susceptibleness to interference by other surrounding structures, as well as difficulty in evaluatiing the overall erm. CT scans of the chest aortic formation overcome the weaknesses of the arterial Doppler ultrasound, for clearer images but puts the patient at risk of X-ray exposure.

2. In what cases does a thoracic aortic resonance imaging be in order to be taken?

Chest aortic resonance imaging is inorable in thoracic aortic diseases for the purpose of diagnosis and coordination of treatment planning. However, because the procedure is time-consuming, chest aortic MRI scans have not been able to really replace the role of computer-layered scans in urgent diseases, especially in small centers. Chest aortic MRI scans are usually preferred when the patient is stable,

MrI scans of chest aortic arteries include:

  • Congenital thoracic aortic stenosis
  • Aortic inflammation
  • Chest aortic aneurysm
  • Dissection of the thoracic aortic
  • Atherosclerosis of the chest aortic
  • Aortic anatomy abnormalities

3. In what cases is it contraintent to a thoracic aortic resonance imaging?

Word resonance is a safe and effective non-invasive medium. However, chest aortic MRI scans are not always allowed.

Contraintent chest aortic resonance imaging includes:

  • Person with closed chamber scare syndrome: The res resonance imaging process requires the patient to lie still in a position under the shooting chamber for a period of time. People with closed chamber fear syndrome may not cooperate to give quality images. In some cases the doctor may have to prescribe sedatives.
  • Patients carrying iron-containing foreign objects or alternative materials, which are from a pacemaker, artificial cochlear, artificial heart valves, bone combination means, clips for the treatment of vascular disease, … The field waves can damage these devices and affect the health of the person.
  • Patients with metallic foreign bodies in the eyes, or shrapnel in the body, are also not in the entile of chest aortic MRI scans.

4. What should the patient prepare before a chest aortic scan?

Some points of note that the patient needs to remember before conducting an MRI scan of the chest aortic:

  • Patients do not need fasting if they have a non-medicinal MRI scan. With MRI with photothrity, patients should remember not to eat or drink anything 4 hours earlier.
  • Do not wear jewelry, earrings or anything made of metal such as watches, bank cards.
  • Daily oral medications for chronic conditions such as hypertension and diabetes can still be used normally as prescribed by your doctor.
  • A detailed declaration of a history of the disease, including a history of surgical implantation of artificial materials to detect contraintation if any.

5. Steps to perform a chest aortic scan

Chest aortic MRI scans should be performed in accordance with the procedure to ensure the safety of the patient as well as ensure the best image quality.

Steps to perform a chest aortic scan include:

  • Preparation of the resymable machine and basic tools
  • Advise and explain clearly to patients the steps taken in the res resonance imaging procedure.
  • Exploit historical information, medical history in detail to exclude contrained.
  • Ask the patient to remove jewelry and personal items, change clothes as prescribed before entering the MRI room. Family members traveling with the patient are also not allowed to bring metal items into the shooting room.
  • Instruct the patient to lie on his back on the chair, tie the cord to check the breathing level at the waist level, not to tie too tightly or too loosely.
  • Instruct patients to follow the technician's instructions
  • Mri scans cause a lot of noise, so it is necessary to equip patients with noise-reducing means such as earplugs or noise-cancelling headphones.
  • The total time for a shot can be up to 1 hour.
