Objective Improvement

Objective: improvement of the quality of prenatal diagnosis of brain tumors using different ray diagnostic techniques. Materials: the case of prenatal diagnosis of hemangioma of the cerebellum at 25 weeks of gestation with ultrasound and magnetic resonance imaging is presented. The diagnosis was verified by post-mortem examination. Results: the publications about the prenatal diagnosis of hemangiomas and other brain tumors over the past 30 years are presented. Conclusion: representation of the features of the ultrasound and MRI picture of fetal brain tumors and the timing of their manifestation allows to organise algorithm of prenatal diagnosis. The prognosis for the fetus in the presence of brain tumors, regardless of the nature of the tumor, should be regarded as unfavourable.

Magnetic Resonance Imaging Mri

Diagnostic studies carried out using any medical equipment require comprehensive control, which is provided by a number of regulatory documents. Particular attention is paid to X-ray imaging methods, but in the field of magnetic resonance imaging (MRI), one can notice both the lack of this attention and the multidirectional efforts to normalize. This is understandable - this diagnostic method is not based on the use of ionizing radiation, and although magnetic fields have some effect on human health, especially on personnel who work in MRI rooms all the time, they are safe for patients who come to the diagnostic procedure from time to time. time and do not have in their body foreign metal (steel implants) or electronic (pacemakers, neurostimulators) objects. However, ignorance and non-compliance with both advisory and mandatory requirements can significantly increase the risk of harm to patients or staff, as well as lead to a decrease in the quality of imaging and diagnostics. A separate feature of the field of MRI regulation is that over the past decades, more than a dozen different standards, sanitary norms, rules, letters and recommendations have been published or revised, a significant part of which complement or duplicate each other, or completely contradict each other. As a result, the need to ensure compliance of the MRI room / department with the requirements of regulatory documents is greatly complicated. This paper provides an overview of the regulatory documentation in force in Russia related to the organization and functioning of an MRI room / department, highlights the aspects that are most important from the point of view of safe and high-quality operation, and formulates the steps necessary to modernize the system, both from the point of view of the quality of diagnostics. and the safety of MRI studies.

A case of prenatal diagnosis of the corpus callosum lipoma at 32–33 weeks of gestation is presented. In a consultative examination, a hyperechoic formation with clear contours was found in the projection of the septum pellucidum, occupying the rostrum, genu, and truncus of corpus callosum, without signs of intratumorally blood flow in the color Doppler mapping mode. The prenatal diagnosis of "callosum lipoma" was established, confirmed after the birth of a child during magnetic resonance imaging.
