Ultrasonography

Technological advancement has broadened the training possibilities of simulation in super speciality courses like arthroscopy, endovascular surgery, urology, gynaecology, robotic surgery, endoscopy, ultrasonography and many more.

Almost every rural and urban hospital and family planning clinics in China had a good quality sex discernment equipment by 2001. citation The launch of ultrasonography technology in India too occurred in 1979, but its expansion was slower than China.

Because of frequent ambiguity on ultrasonography examinations, the following classification is proposed: In women with a pregnancy of unknown location, between 6% and 20% have an ectopic pregnancy.

Currently, Doppler ultrasonography is not considered to significantly contribute to the diagnosis of ectopic pregnancy.

Despite these advantages, renal ultrasonography in 2009 was not considered a substitute for noncontrast helical CT scan in the initial diagnostic evaluation of urolithiasis.

Even in rural areas, most women know that ultrasonography can be used for gender discernment.

If serum hCG at 0 hours is more than 1000 IU/L and there is no history suggestive of complete miscarriage, the ultrasonography should be repeated as soon as possible.

It was not until ultrasonography became widely available in urban and rural China that sex was able to be determined scientifically.

Medical applications such as ultrasonography and elastography rely on the ultrasonic frequency range.

Patients with varicose veins should now be investigated using lower limbs venous ultrasonography.

Prenatal sex discernment main Ultrasonography image showing the fetus is a boy.

The main reason for this is that compared with CT, renal ultrasonography more often fails to detect small stones (especially ureteral stones), as well as other serious disorders that could be causing the symptoms.

The rationale is that a low β-hCG level may indicate that the pregnancy is intrauterine but yet too small to be visible on ultrasonography.

There have been technical advances in ultrasonography.

The ultrasonic systems used in medical ultrasonography employ piezoelectric transducers.

Transvaginal ultrasonography An ultrasound showing a gestational sac with fetal heart in the fallopian tube has a very high specificity of ectopic pregnancy.

Transvaginal ultrasonography has a sensitivity of at least 90% for ectopic pregnancy.

Ultrasonography (left side of image) in the (a) longitudinal and (b) the transverse planes shows both signs of destruction and inflammation.
