What are CR, DR, CT, magnetic vibration and B-ultrasound in the hospital? What is the difference?

MR, CT, CR, DR, DSA and X-ray are all medical imaging diseases. ?

MRI is a magnetic resonance imaging examination, which can obtain transverse, sagittal and coronal images. Good spatial resolution.

CT is a kind of X-ray diagnostic equipment, and it is also a complicated X-ray equipment, which can obtain tomographic images. Compared with MRI, it is characterized by high density resolution.

CR, DR and X-ray diagnosis, like CT, all complete images through X-rays. The difference is that CR and DR are more advanced than ordinary X-ray machines in image acquisition. CR is an IP board, and DR is more advanced, which is completed by PACS.

DSA is used in interventional surgery. Angiography, digital silhouette and images show the direction of blood vessels, which is convenient for interventional surgery. It is also an X-ray device.

B-ultrasound examination, commonly known as "B-ultrasound", is a medical examination item that patients often come into contact with when they see a doctor. As an important part of imaging diagnosis technology, ultrasonic diagnosis technology does have many advantages over CT and MRI.

1, different judgment methods

Magnetic vibration refers to the phenomenon of spin magnetic resonance.

It has many meanings, including nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) or electron spin resonance (ESR).

Ultrasound has many forms in disease diagnosis:

① Diagnosis of diseases in the form of amplitude is called "one-dimensional display". Because the first English letter of amplitude is a, it is called a-ultrasonic, also known as one-dimensional A-ultrasound.

② It is called "two-dimensional display" to diagnose diseases in the form of brightness mode. Because the first English letter of brightness is B, it is called B-ultrasound, also called two-dimensional ultrasound or gray-scale ultrasound.

CT(Computed Tomography), namely computerized tomography, uses precisely collimated X-ray beams, gamma rays and ultrasonic waves.

DR refers to a new digital X-ray photography technology directly controlled by computer, that is, X-ray information penetrating human body is converted into digital signals by using amorphous silicon flat panel detector, and images are reconstructed by computer and a series of image post-processing.

CR is the abbreviation of computer X-ray photography. CR is a medical imaging diagnosis of diseases. It uses digital images, which is convenient to access PACS system, and can be combined with computer technology to process images and improve image quality.

2, the price is different

DR, CT, magnetic vibration and B-ultrasound are all expensive.

The price of CR is relatively low, and a set of CR can realize the digitalization of X-ray equipment in the whole hospital.
