They are, however, often used to image internal organs and often used in prenatal care. CT Scans, on the other hand, can be used to image (in great detail) soft tissue, bone, and blood vessels, and do all of this at the same time. ... Ultrasound is often used to image muscles, internal organs, tendons, etc.

These devices work by using high-frequency sound waves to map out the image. Ultrasounds are very good at doing what they were designed to do, but they do have limitations. ... CT Scans, on the other hand, can be used to image (in great detail) soft tissue, bone, and blood vessels, and do all of this at the same time.

The abdominal ultrasound examination examines the abdominal and pelvic organs. Abdominal ultrasound examines the state of the liver, gall bladder, pancreas, spleen and kidneys, while the pelvic ultrasound examines the bladder, the womb, the ovaries and the prostate in men.

Both machines are designed to take images of selected, internal parts of the body. They are often even used on the same areas of the body! What, then, is the difference between a CT and a MRI scan? While MRI and CT scanners look similar and serve many of the same purposes, they are not the same machine.

The difference between a 'limited' ultrasound exam and a 'complete' ultrasound exam is: ... Many emergency department ultrasounds are more focused than “complete.” As defined by CPT, a limited ultrasound exam is one in which less than the required elements for a complete exam are performed and documented.

Ultrasound imaging (sonography) uses high frequency sound waves, to create a live video feed image of the inside of the body. ... Unlike X-ray imaging, there is no radiation exposure associated with ultrasound imaging. During an ultrasound exam, a probe called a transducer is placed directly on the skin or inside the body.

A CT (computerized tomography) scan is a combination of a series of X-ray images taken at different angles; the CT uses a computer to create images from these X-rays. An MRI (magnetic resonance imaging) is a scan that uses magnetic fields and radio waves to produce a detailed image of the body's soft tissues and bones.

What is the difference between a CT angiogram and a CT scan with IV contrast? An angiogram is a specific type of CT scan with contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest.

There's absolutely no difference between ultrasound technologists or technicians, or so says ONET OnLine, which also uses the term “sonographer” for the same profession. These health care professionals make pictures of your body's insides using high-frequency sound waves, which can't hurt you like X-ray radiation can.

Forney says. MRI and ultrasound look at the body in different ways. MRI, which uses powerful magnets to produce 3-D anatomic images, is a high-contrast resolution modality that can determine changes in the tissue quality.

For instance, the CT is much better at screening for certain types of cancer tumors and finding various abnormalities within the body. Also, CT can be used with other screening techniques like MRI's to further enhance its accuracy and definition. Ultrasound is often used to image muscles, internal organs, tendons, etc.

Chest CT scan allows for a more detailed view compared to a chest X-ray. ... Chest X-ray provides a 2D image, while a chest CT scan is able to produce a 3D view of your organs. An X-ray is built to examine dense tissues, while a CT scan is better able to capture bones, soft tissues and blood vessels all at the same time.

Ultrasound is good at evaluating superficial lumps, but a mammogram is better able to note abnormalities deeper in breast tissue. Ultrasound doesn't show microcalcifications, the minute accumulation of calcium around a tumor and the most common feature seen on a mammogram.

A CT scan can be wrong: it can't tell the difference between cancerous tissue and non-cancerous tissue. CT scans can be misread or misinterpreted. Imaging tests usually can't tell if a change has been caused by cancer. CT scans can produce false negatives and false positives.

Although often used interchangeably, ultrasound is the procedure of using sound waves to create images from inside the body. Sonogram is the image produced by an ultrasound examination.

An ultrasound is a tool used to take a picture. A sonogram is the picture that the ultrasound generates. Sonography is the use of an ultrasound tool for diagnostic purposes.

Radiology technologists specialize in radiation imaging and therapy, using X-ray, computer tomography and medical resonance imaging to capture images of the human body. On the other hand, sonographers are trained to use ultrasound technology, which emits sound waves to take internal images of the body.
