Fetal Medicine

CRIFM Prenatal Medical Clinic was born as the first facility in Japan specializing in fetal medicine and fetal Dock. Our president, Dr. Pooh, is highly regarded by international academic societies and receives many requests for lectures from academic societies and research groups in Japan and abroad. Dr. Pooh will give an easy-to-understand explanation of fetal medicine.

Growth during pregnancy

With the advancement of ultrasound equipment, we can now see the process of the gradual formation of organs and nerves from the fertilized egg, which is only about 1 mm in diameter. The following is an explanation of how the fetus grows and the process of fetal development. We will also introduce the time when the face becomes clear, the time when the sex of the fetus becomes known, and the growth graphs for each body part (abdominal circumference, femur length, weight, and head).

About fetal diseases

There are many types of congenital diseases of the fetus, and it is said that one out of dozens of fetuses is born with some kind of disease. CRIFM's prenatal diagnosis can test for most of them.

What is chromosome?

Chromosome testing is an important part of prenatal diagnosis to check for abnormalities in the fetus. The chromosomes can be checked for the presence of congenital diseases. In this section, Dr. Pooh will explain the diseases that can be confirmed, chromosomal abnormalities that may be involved in diseases such as 21-trisomy, 18-trisomy, 13-trisomy, XY chromosome, and microchromosomal abnormalities that have recently been attracting attention. In addition, the types of chromosome tests, the characteristics of each test method, and precautions to be taken when visiting a doctor will be introduced.

Prenatal tests for chromosomal abnormalities

In the Early fetal Dock (CRIFM) screening test, both genetic and morphological diagnoses can be made by using precision ultrasonography. When should I have a screening test? This article also explains when to take the screening test and when to make the diagnosis.

What is NT?

NT is an acronym for Nuchal Translucency, a swelling on the back of the fetus's neck around 11-13 weeks of gestation. Thick NT is sometimes seen as a sign of fetal disease, but what is it really? What is it? Dr. Pooh, a certified FMF physician with international NT certification, will answer a variety of questions about NT.

What is the OSCAR test?

Maternal serum markers are used to test for the presence of chromosomal abnormalities in the blood of pregnant women. However, the diagnostic results cannot be 100% guaranteed, and the results may differ even for the same fetus depending on the facility. The reason for this is the accuracy of NT measurement, and at CRIFM, our experts in precision ultrasound NT measurement diagnose NT and combine it with two maternal serum markers, PAPP-A and free beta-hCG, to increase the accuracy of diagnosis. This article explains the rationale behind the combination of these tests.

What is NIPT?

NIPT is a test to detect chromosomal abnormalities such as trisomy 21, 18, and 13 by analyzing DNA fragments of fetal cells in the mother's blood. This article explains what NIPT can tell us and the sensitivity and specificity of NIPT.
