By MICHELLE FALCONA-SOUTHERN BAY, FLORIDA (AP) When an ultrasound doctor is doing a basic checkup, the ultrasound device in the room will not only tell him the exact position of the pelvis, it also gives him a good idea of what size a woman is.
But sometimes, it’s not so simple.
A woman’s heart rate may fluctuate or a scan of her chest may show the heart is too far out.
So a doctor may want to do an ultrasound test to find out if that is the case.
When that happens, the doctor may be told to “get a fake ultrasound.”
The test, called a “tensor-spatial” ultrasound, uses ultrasound waves to look for anomalies in a woman’s chest and pelvic region, but doesn’t tell a person exactly how the patient feels.
Some doctors say a fake can provide a better, more accurate ultrasound test.
A fake ultrasound is often referred to as a “faker,” but in this case, it has the same name as a common medical diagnostic device.
But in the United States, there is no such device that can perform a true ultrasound, according to a U.S. government advisory group.
That means the real thing is better than the fake, said Jennifer M. Kneebone, a professor at the University of California, San Francisco.
In fact, a fake is often more accurate than a real one.
In a study published last month in the journal Surgery, researchers at the U.K. University of Sheffield and elsewhere compared the accuracy of two different types of ultrasound test — one that used real ultrasound waves, and one that looked at a person’s chest-pancreas response to a fake.
The fake test performed by a doctor, for example, can provide better information than a fake, the researchers said.
But when the fake is done by a nurse, the results can be unreliable because the nurse can’t always tell if a nurse was doing the test correctly, or whether the person was actually lying on a table.
For the study, the Sheffield team looked at over 3,000 ultrasound tests done by over a dozen doctors in the U
