1. What is a Magnetic Resonance Imaging (MRI)? Magnetic Resonance is a diagnostic imaging technique that uses a magnetic field and radio waves to obtain detailed images of the inside of the body, without using ionizing radiation such as X-rays.
 
2. What does 1.5 Teslas mean? 1.5 Teslas refers to the intensity of the magnetic field used in the equipment. A Tesla is a measure of the strength of the magnetic field. MRI machines in hospitals and clinics are typically in the 1.5 to 3 Tesla range. A magnetic field of 1.5 Tesla provides high quality images.
 
3. Siemens Aera Siemens is a leading medical technology company. Their "Aera" model is one of the most renowned 1.5 Tesla MRIs, known for its high performance, open design and excellent image quality.
 
4. Obstetric Use: Magnetic Resonance in obstetrics is a valuable tool for detailed evaluation of the fetus and uterus. Although theultrasound is the primary method for fetal monitoring, MRI provides complementary vision, especially in cases where a clearer or more detailed image is required:
 
Fetal Anomalies: MRI can accurately identify and characterize fetal malformations, especially those in the brain, spine, or large organs.
 
Placenta: It allows the position and structure of the placenta to be evaluated, identifying conditions such as placenta previa or placental accreta.
 
Amniotic fluid: It helps in evaluating the amount of amniotic fluid and can identify conditions such as polyhydramnios or oligohydramnios.
 
Maternal Evaluation: It can detect conditions affecting the mother, such as uterine fibroids, which could have implications for pregnancy.
 
It is important to highlight that the Magnetic Resonator (Magnetic Resonance) does not use radiation,which makes it safe for the fetus and the mother. However, its use must be justified and carried out only when necessary to obtain information that cannot be obtained throughultrasound.
 
5. Advantages for the patient The Aera's open design is particularly beneficial for pregnant women, who may feel uncomfortable or claustrophobic in more closed MRI machines. Additionally, the equipment minimizes noise, reducing stress during the exam.
