What is Indications for Cardiac Magnetic Resonance?

Cardiac magnetic resonance (CMR) is an advanced diagnostic method that provides the highest-resolution, radiation-free assessment of cardiac anatomy, function and tissue properties. Gadolinium-enhanced studies offer unique information on myocardial fibrosis, edema and necrosis.

Late gadolinium enhancement (LGE) patterns are crucial for differentiating cardiomyopathies: subendocardial LGE suggests ischemic disease, mid-wall LGE suggests dilated cardiomyopathy and patchy LGE suggests hypertrophic cardiomyopathy or sarcoidosis.

T1 and T2 mapping techniques add information about diffuse myocardial diseases (amyloidosis, Anderson-Fabry, myocarditis). Stress perfusion CMR is used for functional assessment of coronary ischemia.

CMR is indicated for cardiomyopathy workup and classification, myocarditis, cardiac tumors, pericardial disease, congenital heart disease and arrhythmic risk stratification.

Symptoms

CMR is a diagnostic test; common indications include:
Unexplained LV hypertrophy or dilated cardiomyopathy
Suspected myocarditis (chest pain with elevated troponin)
Evaluation of a cardiac mass
Functional testing for suspected coronary ischemia
Risk stratification for arrhythmia

Risk Factors

MR-incompatible implants (older pacemakers, metallic prostheses)
Severe claustrophobia
Gadolinium risk (NSF) in advanced renal failure
Relative contraindication in first-trimester pregnancy

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When the etiology of cardiomyopathy needs clarification
  • For diagnosis and follow-up of myocarditis
  • Suspected cardiac tumor or infiltrative disease

Treatment Methods

01
CMR is a diagnostic tool; treatment is directed at the identified pathology
02
Decision regarding immunosuppression when myocarditis is detected
03
Specific therapy based on cardiomyopathy subtype
04
ICD decision based on LGE pattern
05
Follow-up CMR to assess treatment response

Hypertension (High Blood Pressure)

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
