Аннотация
BACKGROUND: Micro-computed tomography (micro-CT) offers high-resolution, three-dimensional imaging of embryonic structures, overcoming limitations of standard autopsy in early loss of pregnancy.
OBJECTIVE: To assess the feasibility and relevance of micro-CT imaging in the anatomical study of a human embryo obtained from ectopic pregnancy.
MATERIALS AND METHODS: Following laparoscopic salpingectomy, a well-preserved 8mm embryo was extracted, fixed in formaldehyde, and stained with iodine-based contrast before being imaged using micro-CT at 12μm isotropic resolution.
RESULTS: The embryo, classified as Carnegie stage 15, was examined in detail. Micro-CT allowed non-destructive 3D visualization of multiple internal structures, including lungs, heart, liver, spleen, neural tube, and craniofacial features.
DISCUSSION AND CONCLUSION: Micro-CT is a promising tool for studying early human development using specimens from ectopic pregnancies. It enables detailed morphological analysis at very early stages, enhances understanding of embryogenesis, and may complement routine postmortem examinations.
