What is CINE MRI of the heart?
CINE MRI of the heart is a magnetic resonance imaging that provides detailed information necessary to analyse the heart muscle movement. The MRI images are then rearranged to form a dynamic video of the heart movement.
What is the purpose of CINE MRI of the heart?
The CINE MRI studies the anatomy and functionality of the heart and reveals potential diseases, both congenital and acquired. The data obtained from this study is considered to be more reliable in terms of measurements of volume, mass and function of the heart. It also provides enough information to analyse foyers, large vessels and their scope as well as the function of the heart valves.
CINE MRI of the heart does not require special preparations unless the examination requires the use of a contrast agent. In this case, it is required that the patient does not ingest any food or liquids for at least 4 hours prior to the exam. The patient is also required to bring previous medical information as well as recent evaluation of renal function and to inform medical staff of any allergies.
All metal or magnetic objects, makeup and contact lenses should be removed before the exam. There should not be any problems for patients with coronary stents, sternal, post-cardiac surgery sutures and dental implants.
If the exam includes the evaluation of perfusion under pharmacological stress, the patient is also required to refrain from ingesting tea, coffee, chocolate and energy drinks in the 12 hours before the exam.
It is essential that the patient bring all cardiac documentation available, because it may help determine the course of treatment and examination protocol.
Which patients can undergo the examination?
The exam is not recommended for people with pacemakers or magnetically active devices such as electrodes, neurostimulators and dentures because they do not have an ascertainable compatibility with magnetic fields. The exam is also not recommended during the first trimester of pregnancy.
Patients with pacemakers that are compatible with MRI should disclose that information to medical staff due to the difference in protocol. Any concern about presence of metal parts in the body should be verified before the examination.
Is the examination painful or dangerous?
The exam is neither painful nor dangerous. The machine causes noise, which may cause slight discomfort and annoyance. However, headphones may be provided to reduce the noise.
How is CINE MRI of the heart performed?
The patient lies on a bed horizontally. Electrodes and surface coils are painlessly placed to monitor the heartbeat. A successful MRI requires the patient to hold their breath for approximately 10 seconds in order to eliminate motion and respiratory artefacts.
It is likely that a contrast agent will be administered intravenously midway through the exam. The average duration of the exam is 30 minutes; however, it may vary from person to person.
