Magnetic resonance imaging (CHT) is one of the methods used for prenatal diagnosis. With outstanding advantages, MRI will bring accurate results of fetal nervous system abnormalities and other fetal malformations.

1. Does magnetic resonance imaging affect the fetus?

CT scan will be completely safe for any subjects: pregnant women, normal people, fetal stages.
This is a diagnostic method that is harmless to both mother and baby. Pregnant women will not be exposed to radiation or feel pain.
However, doctors will recommend MRI scans only for pregnant women when the gestational age of the fetus is 13 weeks or more, that is, in the first 3 months of pregnancy, MRI should not be taken. This helps the fetus not to be affected in terms of development as well as health.
For pregnant women, doctors will use MRI method for cases that are difficult to diagnose on ultrasound such as: obese mother, low amniotic fluid, need to assess fetal movements.
Especially contraindicated when the patient has a metal foreign body or implanted device.

2. Advantages of magnetic resonance imaging for detecting fetal malformations

The preeminent feature of MRI is the most accurate and fastest detection of fetal malformations. This is something the ultrasound method will not do. While ultrasound can only detect approximately 50% of neurological abnormalities, magnetic resonance imaging will detect very small lesions and extremely accurately.
Not only the abnormalities of the central nervous system, MRI also detects lesions in other parts such as: fetal organs, especially kidneys, lungs, diaphragmatic hernia ....
Hospital Vinmec International General Clinic put into use a 3.0 Tesla Silent Technology Magnetic Resonator. of GE Healthcare (USA).
Silent technology is especially beneficial for patients who are children, the elderly, weak health patients and patients undergoing surgery. Limiting noise, creating comfort and reducing stress for customers during the shooting process, helping to capture better quality images and shorten the shooting time. Magnetic resonance imaging technology is the technology applied in the most popular and safest imaging method today because of its accuracy, non-invasiveness and non-X-ray use.
