For incidentally detected prenatal hydronephrosis, the first study to obtain is a postnatal renal ultrasound, since as noted, many cases of prenatal hydronephrosis resolve spontaneously. This is generally done within the first few days after birth, although there is some risk that obtaining an imaging study this early may miss some cases of ...
Pyelectasis is a dilation of the renal pelvis.It is a relatively common ultrasound finding in fetuses and is three times more common in male fetuses. In most cases pyelectasis resolves normally, having no ill effects on the baby.
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 ...
Ultrasound can also be used to diagnose pelvic floor dysfunction. Transabdominal, transvaginal, transperineal and endoanal ultrasound (EUS) are important tools for diagnosing pelvic floor dysfunction. For EUS, an ultrasound probe is inserted into the anal canal and can be used to visualize and assess the anatomy and function the pelvic floor. [18]
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Vaginal ultrasonography is a medical ultrasonography that applies an ultrasound transducer (or "probe") in the vagina to visualize organs within the pelvic cavity. It is also called transvaginal ultrasonography because the ultrasound waves go across the vaginal wall to study tissues beyond it.
This is known as Magnetic Resonance guided Focused Ultrasound (MRgFUS) or High Intensity Focused Ultrasound (HIFU). These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI.
Therapeutic ultrasound refers generally to the use of ultrasound for the treatment of a medical condition or for therapeutic benefit. Physiotherapeutic ultrasound was introduced into clinical practice in the 1950s, with lithotripsy introduced in the 1980s. [ 1 ]
