Area of Science:
- Medical imaging
- Cardiology
- Pediatrics
Background:
- Congenital heart disease (CHD) diagnosis often relies on ultrasound.
- Quantitative cardiovascular data can be crucial for CHD management.
- Fetal cardiovascular MRI presents a developing diagnostic modality.
Purpose of the Study:
- To review the current state of fetal cardiovascular MRI.
- To summarize clinical applications of this technique.
- To highlight ongoing technical advancements.
Main Methods:
- Review of existing literature on fetal cardiovascular MRI.
- Analysis of technical capabilities and limitations.
- Summary of clinical use cases in prenatal CHD.
Main Results:
- Fetal cardiovascular MRI is valuable when ultrasound is inconclusive for CHD.
- It provides essential quantitative data on blood flow, oxygen saturation, and hematocrit.
- Technical limitations exist but are being addressed by ongoing advances.
Conclusions:
- Fetal cardiovascular MRI is a promising diagnostic tool for CHD.

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

215
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,...

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...

602
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
