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.
It is iso-echogenic to the thyroid gland with no definite connection to the thyroid gland. b Transverse colour Doppler ultrasound shows significant increase in vascularity. c Axial enhanced neck CT scan at the level of thyroid cartilage demonstrates midline infrahyoid hyperdense soft tissue mass (white arrow) embedded within the strap muscle.

A study published in 2004 was done to establish the sensitivity of ultrasound in the diagnosis of a nuchal cord. Each of 289 women, induced the same day, underwent a transabdominal ultrasound scan with an Aloka 1700 ultrasound machine with a 3.5 MHz abdominal probe, using gray-scale and color Doppler imaging immediately prior to induction of ...
Any sudden changes in direction of blood flow produces audible sounds on the ultrasound machine. [3] In spectral Doppler, the y-axis shows the direction and velocity of the flow. Meanwhile, the x-axis (as known as "baseline") shows the flow over time. The gradient at any point on the waveform would therefore shows the acceleration of the flow ...
An ultrasound to measure blood flow Angiography, which involves injecting a dye into your blood vessel to help doctors see obstructions with X-rays or computed tomography (CT) scans
Ultrasound computer tomography (USCT), sometimes also Ultrasound computed tomography, Ultrasound computerized tomography [1] or just Ultrasound tomography, [2] is a form of medical ultrasound tomography utilizing ultrasound waves as physical phenomenon for imaging. It is mostly in use for soft tissue medical imaging, especially breast imaging ...

A water-based gel is applied to the infant's head, over the anterior fontanelle, to aid conduction of ultrasound waves. Ideally scans are performed during sleep or when the infant is calm. The operator then uses an ultrasound probe to examine the baby's brain, viewing the images on a computer screen and recording them as necessary. [citation ...
