Magnetic resonance imaging does not always confirm left ventricular noncompaction
International Journal of Cardiology
|August 29, 2006
Summary
Left ventricular hypertrabeculation/noncompaction (LVHT) can be missed by cardiac magnetic resonance imaging (CMRI) due to image quality issues. Echocardiography confirmed LVHT in a patient where CMRI failed to visualize the condition.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left ventricular hypertrabeculation/noncompaction (LVHT) is a congenital heart condition.
- Diagnosis is typically achieved through echocardiography or cardiac magnetic resonance imaging (CMRI).
Observation:
- A 48-year-old woman with peripheral embolism and an undiagnosed neuromuscular disorder presented with LVHT diagnosed via echocardiography.
- The spongiform trabecular meshwork was observed in the lateral and posterior walls of the left ventricle.
Findings:
- Cardiac magnetic resonance imaging (CMRI) failed to visualize the LVHT, showing only a thickened structure.
- Potential reasons for CMRI failure include image artifacts, limited resolution, and atypical LVHT location.
Implications:
- CMRI may not reliably detect LVHT in all cases.
- Echocardiography remains a crucial tool for diagnosing LVHT, especially when CMRI is inconclusive.
- Further research into optimizing CMRI techniques for LVHT detection is warranted.

01:21Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
