[COMPARISON OF ULTRASOUND INVESTIGATION METHODS IN POSTMENOPAUSE].

Accurate assessment of endometrial health is essential in postmenopausal women to detect potential pathology. Prior research has shown that 2D ultrasound is commonly used, but it may lack sensitivity in identifying subtle changes. No prior work had resolved how combining 2D and 3D ultrasound could improve diagnostic accuracy. This gap motivated the investigation into advanced imaging techniques. It was already known that endometrial thickness alone is not sufficient for diagnosis. However, the role of vascularization and 3D metrics remained unclear. This uncertainty drove the need for a comparative study. The study aimed to address limitations in current diagnostic methods.

The study sought to evaluate the effectiveness of combining 2D and 3D ultrasound in diagnosing endometrial pathology in postmenopausal women. Specifically, it focused on how adding 3D Doppler indices and volume measurements could enhance diagnostic accuracy. The motivation was to improve preoperative diagnostic criteria for hysteroscopy. The researchers proposed that vascularization is a key diagnostic indicator. This approach could reduce unnecessary procedures and improve patient outcomes. The study aimed to compare traditional 2D methods with advanced 3D techniques. By analyzing vascularization and volume data, the study aimed to refine diagnostic standards. The goal was to establish clearer criteria for identifying endometrial changes.

The study involved 167 postmenopausal women who underwent both 2D and combined 3D ultrasound examinations. The 3D study included volume calculations and Dopplerometric indices like vascularization index and blood flow index. Hysteroscopy and endometrial biopsies were performed for histological confirmation. The researchers compared echographic and Dopplerometric criteria across groups with benign changes and atrophic endometrium. A retrospective analysis was conducted to evaluate the diagnostic accuracy of each method. The study used statistical analysis to determine differences in vascularization and volume between groups. The primary focus was on how vascularization correlates with pathology. The methods were designed to assess the added value of 3D imaging in diagnosis.

The combination of 2D and 3D ultrasound increased sensitivity by 12% and specificity by 13% compared to 2D alone. Echographic criteria showed statistical differences between hyperproliferative and atrophic endometrium groups. Dopplerometric indices revealed significant differences in vascularization between pathology and atrophy. 3D reconstruction provided clearer visualization of endometrial structure. The study found that vascularization is a stronger indicator than endometrial thickness. No significant differences were observed in synechia and cystic atrophy groups. The results suggest that vascularization is a key diagnostic marker. These findings support the use of 3D imaging in preoperative assessments.

The authors propose that 3D ultrasound combined with Dopplerometric indices improves diagnostic accuracy in postmenopausal women. They suggest that vascularization is a more reliable indicator than endometrial thickness. The study highlights the value of 3D reconstruction in identifying pathology. The findings support the use of combined 2D and 3D methods in clinical practice. The researchers suggest that these methods can refine preoperative diagnostic criteria. The study does not claim that vascularization is the only diagnostic factor. The results indicate that 3D imaging enhances sensitivity and specificity. The authors emphasize the need for further validation of these methods.
