Problems solved by technology

After scanning the mother's body, the examination technician found that the three planes of the fetal head were not correct. When the mother's three-dimensional positioning could not determine the standard position, the traditional method was used for positioning. The anatomy is unfamiliar and easy to repeat positioning, which prolongs the inspection time. Different in the actual scan The consistency and standardization of images scanned by technicians is poor

experiment example

[0055] A total of 50 pregnant women who received MRI examination of fetal head in Chengdu Women and Children's Central Hospital and whose fetal head was not correct on the coronal and sagittal axis of the mother were continuously collected. They were divided into group A and group B according to the scanning positioning method.

[0056]In group A, 27 cases were examined by using traditional methods to locate, excluding 1 case of pregnant woman vomiting and 1 case of scan failure (frequent fetal movement), and finally 25 cases were included as the control group;

[0057] In group B, 28 cases were checked using the three-point-one-plane positioning method, and 1 case of claustrophobia, 1 case of polyhydramnios, and 1 case of pregnant women who could not persist were excluded. Finally, 25 cases were included as the experimental group.

[0058] Group A was 24-36 years old [mean (28.68) years old], 25-37 weeks pregnant [mean (31.6) weeks]; group B was 19-35 years old [mean (28.5) ye...

Abstract

The invention relates to a fetal craniocerebral scanning three-point plane positioning method. The method comprises the following steps: searching a fetal craniocerebral fossa or craniocerebral crest, and performing positioning by taking the fetal craniocerebral fossa or craniocerebral crest as a first site; then, searching for a fetal eyeball by taking a the first site as an original point, and performing positioning with the left eyeball as a second site and the right eyeball as a third site; quickly scanning the fetus to obtain an axial view or oblique axis sequence; performing sagittal view and coronal view confirmation and positioning on the sequence; determining a standard axis view on the sagittal view and the coronal view to obtain a coronal sagittal axis; scanning in three directions around the coronal sagittal axis to obtain a standard body position of the fetus; and by taking the standard body position as a contrast, scanning other parts and performing quick capturing and imaging. The invention can quickly find the opposite front side of the fetus, is beneficial to positioning the head and the five sense organs of the fetus and shortens the scanning time, so that a pregnant woman does not need to lie for a long time, and the problem that the fetus cannot use a sedative or the movement of the fetus cannot be controlled so that accurate scanning cannot be achieved is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a three-point plane positioning method for fetal brain scanning. Background technique [0002] With the progress of the country and the development of social and economic levels, prenatal and postnatal care is a concern of every family, and reducing the incidence of fetal birth defects is the top priority of women and children's hospitals! In the past ten years, with the development of fast-sequence magnetic resonance, fetal magnetic resonance has been widely used in my country and has become one of the important prenatal imaging examinations. Magnetic resonance has a high resolution of soft tissue, and can image in multiple directions. It can well display the brain structure of the fetus. It is one of the important means of prenatal diagnosis of fetal head diseases. Magnetic resonance has no radiation, no radiation damage to fetuses and pregnant women, and will not caus...
