Overview of Cardiac MRI

A Cardiac MRI (Magnetic Resonance Imaging) is a highly advanced, non-invasive imaging test that uses magnetic fields and radio waves to produce detailed, high-resolution images of the heart. It shows the heart’s structure, muscle function, blood flow, and tissue characteristics with exceptional clarity. Under the expert guidance of Dr. Karthik Raghuram, Cardiac MRI is used to diagnose complex heart conditions, assess disease severity, and guide precise treatment plans.

Why Cardiac MRI Is Important

Cardiac MRI provides information that other tests like ECG, Echo, or CT scan may not fully reveal. It is especially valuable for:

• Evaluating heart muscle damage

• Diagnosing cardiomyopathies

• Detecting inflammation or scarring

• Assessing congenital heart disease

• Measuring heart chamber size and function

• Evaluating blood flow and valve performance

• Planning surgeries or advanced interventions

Its accuracy makes it a gold-standard imaging tool in modern cardiology.

When Should You Consider a Cardiac MRI?

A Cardiac MRI is recommended if you have:

• Unexplained chest pain

• Irregular heartbeat (arrhythmia)

• Suspected heart muscle weakness

• History of heart attack

• Congenital heart abnormalities

• Heart valve disease

• Previous unexplained fainting episodes

• Abnormalities detected in Echo or CT scan

It is also used to follow up on conditions like heart failure, myocarditis, sarcoidosis, and cardiomyopathies.

How Cardiac MRI Is Performed

Cardiac MRI is safe, non-invasive, and highly detailed:

• You lie in a large MRI scanner

• ECG leads may be attached to time the images with your heartbeat

• A contrast dye may be used to enhance clarity

• The scanner captures images over 30–60 minutes

• There is no radiation exposure

• The procedure is painless, though lying still is required

Dr. Karthik ensures complete comfort, clear instructions, and accurate interpretation of results.

Types of Cardiac MRI

1. Function & Structure MRI

Shows heart chambers, muscle thickness, and pumping function.

2. Perfusion MRI

Evaluates blood flow to the heart muscle.

3. Viability MRI

Identifies scar tissue and assesses whether damaged heart muscle can recover.

4. Congenital Heart Disease MRI

Provides detailed imaging for structural abnormalities present from birth.

5. Aortic MRI

Evaluates diseases of the aorta, including aneurysms and dissections.

Each type of MRI is selected based on the patient’s condition and clinical requirements.

Conditions Detected by Cardiac MRI

Cardiac MRI helps diagnose:

• Cardiomyopathy (dilated, hypertrophic, restrictive)

• Myocarditis and inflammation

• Heart attacks and scar tissue

• Congenital heart disease

• Valve abnormalities

• Pericardial disease

• Aortic conditions

• Pulmonary hypertension

• Right and left ventricular dysfunction

It offers some of the most precise cardiac data available in medicine.

When to Seek Immediate Evaluation

Seek urgent care if you experience:

• Sudden chest pain

• Severe shortness of breath

• Fainting episodes

• Rapid or irregular heartbeat

• Symptoms of heart failure

These signs may require immediate investigation.
