Does different ultrasound machines give different results?

Does different ultrasound machines give different results?

Introduction: Recent studies have reported variations of up to 30\% between different ultrasound machines for tissue Doppler imaging (TDI), a problem that can significantly impact clinical diagnosis, patient management and research studies.

Can ultrasound be wrong?

By the midpoint of pregnancy, an ultrasound can give you a pretty good prediction of your baby’s sex (if you want to know). But it is possible for the ultrasound prediction to be incorrect, and you’ve probably heard stories about people who have prepared for the boy they saw on ultrasound who was actually a girl.

What are the two modes of ultrasound?

The term “duplex” refers to the fact that two modes of ultrasound are used, Doppler and B-mode. The B-mode transducer (like a microphone) obtains an image of the vessel being studied. The Doppler probe within the transducer evaluates the velocity and direction of blood flow in the vessel.

What’s the difference between an ultrasound and a sonogram?

Often, the terms sonogram and ultrasound are used interchangeably. However, there’s a difference between the two: An ultrasound is a tool used to take a picture. A sonogram is the picture that the ultrasound generates.

Will I get my ultrasound results straight away?

You may be told the results of your scan soon after it’s been carried out, but in most cases the images will need to be analysed and a report will be sent to the doctor who referred you for the scan. They’ll discuss the results with you a few days later or at your next appointment, if one’s been arranged.

Can baby position affect ultrasound measurements?

The position your baby’s lying in, and your own height, shape and tummy muscles can all affect the measurement too. Babies also grow at slightly different rates.

Will I get ultrasound results straight away?

What is the difference between a-mode and B-mode ultrasound?

B-mode scans produce a two-dimensional image of the underlying tissue, while A-mode scans result in a waveform with spikes or peaks at the interface of two different tissues (e.g., where subcutaneous fat and muscle meet). Both A-mode and B-mode ultrasound have been used to measure subcutaneous fat thickness.

What ultrasound can detect?

A type of ultrasound, called an echocardiogram, can also provide a picture of how well blood flows through the heart and blood vessels, as will as imaging heart structures. In the abdomen ultrasound can help check for kidney stones, gallstones, liver disease, and the cause of stomach pain.

How much does an ultrasound tech make?

An ultrasound technician makes an average of $57,001 per year, with some technicians making as high as $96,490 per year. Sonography is a lucrative career with ample growth opportunities.

Who reads ultrasound results?

A radiologist, a doctor trained to supervise and interpret radiology exams, will analyze the images. The radiologist will send a signed report to the doctor who requested the exam. Your doctor will then share the results with you. In some cases, the radiologist may discuss results with you after the exam.

How does ultrasound technology work?

The technologist applies a small amount of gel to the area under examination and places the transducer there. The gel allows sound waves to travel back and forth between the transducer and the area under examination. The ultrasound image is immediately visible on a video display screen that looks like a computer monitor.

What is the difference between conventional and 3-D ultrasound?

Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images. A Doppler ultrasound study may be part of an ultrasound examination.

What types of ultrasound devices do we offer?

You’ll find that we offer ultrasound devices suitable for applications such as abdominal, cardiac, musculoskeletal, vascular, thyroid, transcranial, venous, and obstetrical imaging procedures. We have General Electric, Siemens, and Philips ultrasound machines for sale.

What is another name for an ultrasound scan?

Other names for an ultrasound scan include sonogram or (when imaging the heart) an echocardiogram. The ultrasound machine directs high-frequency sound waves at the internal body structures being examined. The reflected sounds, or echoes, are recorded to create an image that can be seen on a monitor.
