Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity; In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity. Fortunately, gestational sac, yolk sac and embryo are surrounded by hyperechoic (brighter) body tissues.
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.
ovarian fibroma in ultrasound Ovarian tumors by incidence and risk of ovarian cancer, with fibroma at right. [2] Diagnosis is usually made by ultrasonography showing a solid ovarian lesion, or, on some occasions, mixed tumors with solid and cystic components. [1] Computed tomography and magnetic resonance imaging can also be used to diagnose ...
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]
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 ...
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 .
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
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]
