Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Diagnosis [ edit ] Although hematometra can often be diagnosed based purely on the patient's history of amenorrhea and cyclic abdominal pain, as well as a palpable pelvic mass on examination, the diagnosis can be confirmed by ultrasound , which will show blood pooled in the uterus and an enlargement of the uterine cavity.
The finding on transvaginal ultrasound of a thin endometrial lining gives the physician a 99% negative predictive value that the patient does not have endometrial cancer. [3] If a patient had a prior endometrial sampling that was inconclusive, then a transvaginal ultrasound can be used to triage a woman with post-menopausal bleeding. [3]
In most cases, the hydrocele, when diagnosed early during complete physical examination, are small and the testis can easily be palpated within a lax hydrocele. However Ultrasound imaging is necessary to visualize the testis if the hydrocele sac is dense to reveal the primary abnormality. But these can become large in cases when left unattended.
Rohan, originally from Ukiah, California, had an operation on December 6 to remove her entire thyroid gland after a class about ultrasounds alerted her to what was later diagnosed as thyroid ...
Auditory sensation can occur if highâintensity ultrasound is fed directly into the human skull and reaches the cochlea through bone conduction, without passing through the middle ear. [13] Children can hear some high-pitched sounds that older adults cannot hear, because in humans the upper limit pitch of hearing tends to decrease with age. [14]
Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions. The location and severity of arterial narrowings and occlusions can be identified. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity ...
