Is it possible to detect adenomyosis by B-ultrasound?

bIs it possible to perform an ultrasonography test for adenomyosis?

Diagnosis of adenomyosis:

1. B-ultrasound examination Buli waits for histological changes B-ultrasound is irrelevant, the sensitivity of B-ultrasound diagnosis is 63%, and the specificity is 97%. It has been reported that 73% of adenomyosis diagnosed by vaginal B-ultrasound is consistent with the histological diagnosis, with a sensitivity of 95% and a specificity of 74%. The accuracy of abdominal B-ultrasound is similar to that of vaginal B-ultrasound.

The characteristics of B-ultrasound images are:

1The uterus is uniformly enlarged and has clear contours.

2The endometrial lines may remain unchanged or slightly curved.

3 The echogenicity of the uterine cross section is uneven, and sometimes echo-free areas of varying sizes can be seen.

2. MRI often uses T2 dual images to diagnose adenomyosis. The image shows a low-intensity band signal surrounding the strong echo of the normal endometrium. The uneven echo band with a thickness of >5mm is a typical image of adenomyosis. Comparative examination before and after menstruation, image changes are of great significance for diagnosis. When the lesion bleeds, strong echo signals of different sizes can be seen. MRI can distinguish between uterine fibroids and adenomyosis, and diagnose the coexistence of the two, which is very helpful for decision-making methods. This is also the main value of MRI.

3. Hysterosalpingography Since adenomyosis rarely causes uterine cavity deformation, hysterosalpingography is of little diagnostic significance. If the lesion involves the endometrial surface, filling defects may be seen.

4. Myometrial needle biopsy Hysteroscopic myometrial needle biopsy has a high specificity for the diagnosis of adenomyosis, but a low sensitivity. Most scholars believe that unless it is severe adenomyosis, myometrial needle biopsy has no important value in diagnosis. There is no place for routine biopsy in patients with MRI pelvic pain.
