One weakness of adenomatoid tumor ultrasound imaging is that it is only possible if the tumor is hyperechoic. Ultrasonically can help identify if it fits this category or not. This specific characteristic in adenomatoid tumors is variable and can determine whether or not ultrasound is the right technique for the job. [11]
Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
to diagnose and manage gynecologic problems including endometriosis, leiomyoma, adenomyosis, ovarian cysts and lesions, to identify adnexal masses, including ectopic pregnancy, to diagnose gynecologic cancer; in infertility treatments to track the response of ovarian follicles to fertility medication (i.e. Pergonal). However, it often ...
Transvaginal ultrasound of the uterus, showing the endometrium as a hyperechoic (brighter) area in the middle, with linear striations extending upwards from it. Transvaginal ultrasonography is a cheap and readily available imaging test that is typically used early during the evaluation of gynecologic symptoms. [24]
Ultrasonography Hemorrhagic Ovarian Cyst. During pregnancy, ultrasonography is the first-line method for evaluating ovarian cysts. Both transabdominal and transvaginal route of ultrasonography are used with either two-dimensional or three-dimensional modalities. [3] Two-dimensional is more common, but three-dimensional can offer more results. [3]
In premenopausal women, adnexal masses include ovarian cysts, ectopic (tubal) pregnancies, benign or malignant tumors, endometriomas, polycystic ovaries, and tubo-ovarian abscess. The most common causes for adnexal masses in premenopausal women include follicular cysts and corpus luteum cysts .
As ovarian cancer is rarely symptomatic until an advanced stage, [42] regular pre-emptive screening is a particularly important tool for avoiding the late stage at which most patients present. However, A 2011 US study found that transvaginal ultrasound and cancer marker CA125 screening did not reduce ovarian cancer mortality. [43]
Endometrial polyps can be detected by vaginal ultrasound (sonohysterography), hysteroscopy and dilation and curettage. [3] Detection by ultrasonography can be difficult, particularly when there is endometrial hyperplasia (excessive thickening of the endometrium). [2] Larger polyps may be missed by curettage. [10]
