Cardiac MRI Treatment In India At Affordable Low Cost

 

Cardiac MRI 

Detailed MR images allow physicians to better evaluate parts of the body and certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography (also called CT or CAT scanning).

 

Cardiac MRI imaging is performed to help : -

evaluate the structures and function of the heart, valves, major vessels, and surrounding structures (such as the pericardium).
diagnose and manage coronary heart disease and a variety of cardiovascular problems.
detect and evaluate coronary artery disease.
plan a patient’s treatment for cardiovascular problems and monitor patient’s progress.

 

Using cardiac MRI, physicians can : -

examine the size and thickness of the chambers of the heart.
determine the extent of damage caused by a heart attack or progressive heart disease.
detect the buildup of plaque and blockages in the blood vessels.
assess a patient’s recovery following treatment.

 

How does the procedure work ?

Unlike conventional x-ray examinations and computed tomography (CT) scans, MRI does not depend on radiation. Instead, while in the magnet, radio waves redirect the axes of spinning protons, which are the nuclei of hydrogen atoms, in a strong magnetic field. The magnetic field is produced by passing an electric current through wire coils in most MRI units. Other coils, located in the machine and in some cases, placed around the part of the body being imaged, send and receive radio waves, producing signals that are detected by the coils.

A computer then processes the signals and generates a series of images each of which shows a thin slice of the body. The images can then be studied from different angles by the interpreting physician. Overall, the differentiation of abnormal (diseased) tissue from normal tissues is often easier with MRI than with other imaging modalities such as x-ray, CT and ultrasound.

 

How is the procedure performed ?

MRI examinations may be performed on outpatients or inpatients. You will be positioned on the moveable examination table. Straps and bolsters may be used to help you stay still and maintain the correct position during imaging.

Small devices that contain coils capable of sending and receiving radio waves may be placed around or adjacent to the area of the body being studied.

If a contrast material will be used in the MRI exam, a nurse or technologist will insert an intravenous (IV) line into a vein in your hand or arm. A saline solution will drip through the IV to prevent blockage of the IV line until the contrast material is injected. You will be moved into the magnet of the MRI unit and the radiologist and technologist will leave the room while the MRI examination is performed.

If a contrast material is used during the examination, it will be injected into the intravenous line (IV) after an initial series of scans. Additional series of images will be taken following the injection. When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed.

Your intravenous line will be removed. MRI exams generally include multiple runs (sequences), some of which may last several minutes.

The entire examination is usually completed within 30 minutes. MR spectroscopy, which provides additional information on the chemicals present in the body’s cells, may also be performed during the MRI exam and may add approximately 15 minutes to the exam time.

 

What are the benefits ?

MRI is a noninvasive imaging technique that does not involve exposure to radiation.

 

MRI images of the heart are generally clearer and more detailed than with some other imaging methods. This detail makes MRI an invaluable tool in early diagnosis and evaluation of cardiac abnormalities, especially those involving the heart muscle.

 

MRI has proven valuable in diagnosing a broad range of conditions, including cardiac anatomical anomalies (congenital defects, etc.), functional abnormalities (valve failure, etc.), tumors and ischemic and degenerative conditions.

 

MRI can help physicians evaluate both the structure of an organ and how it is working.

 

MRI enables the detection of abnormalities that might be obscured by bone with other imaging methods.

 

The contrast material used in MRI exams is less likely to produce an allergic reaction than the iodine-based materials used for conventional x-rays and CT scanning.

 

Cardiac MRI allows physicians to quickly examine the structures and function of the heart and major vessels, without the risks associated with traditional, more invasive procedures.

 

Cardiac MRI can help in the diagnosis and treatment of patients with following conditions : –

 

                            >    Coronary artery disease
                            >   Congestive heart failure and cardiomyopathy
                            >    Congenital heart disease
                            >    Pericardial disease
                            >    Cardiac masses and thrombi
                            >    Arrhythmia 
                            >    Aortic disease 
                            >    Peripheral vascular disease 
                            >    Valve disease

This study was part of a project running in the Dept. of Radiology, Uniklinikum Goettingen, about the changes in cardiac function during static apnea. 1,5T scan with imaging prior and during apnea. Heart beat was constast about 70bpm. 02 sat. after 270secs was 68%.
