What Are the Different Types of Medical Imaging Techniques? Medical imaging techniques are critical in modern medicine for diagnosing a variety of conditions. X-rays, for example, are often used to detect broken bones and some types of cancer. Computed tomography (CT), in which multiple X-ray images are taken, can provide more detailed images than a standard X-ray.

What Are the Different Types of Medical Imaging Techniques? Magnetic resonance imaging (MRI) scans are one of the more expensive types of imaging system but can provide highly detailed images of organs and structures inside the body. Other forms of medical imaging techniques include ultrasound and nuclear imaging.

Open MRI Vs. Closed MRI Magnetic resonance imaging (MRI) is a radiological study that obtains images with magnets and radio waves. Unlike X-rays and CT scans, MRI uses no radiation. There are three types of MRI machines: closed, open and standing. Closed and open are most commonly used.

Magnetic Resonance Imaging (MRI) of the Spine and Brain Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Unlike X-rays or computed tomography (CT scans), MRI does not use ionizing radiation.ew uses and indications for MRI have contributed to the development of additional magnetic resonance technology. Magnetic resonance angiography (MRA) is a new procedure used to evaluate blood flow through arteries in a noninvasive (the skin is not pierced) manner.

- Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract.Urography with conventional x-ray is known as intravenous pyelogram (IVP). Urography may also be performed using computed tomography (CT) or magnetic resonance imaging (MRI).omputed tomography (CT) urography and magnetic resonance (MR) urography use CT and MR images, respectively, after intravenous contrast material to obtain images of the urinary tract.

Imaging Tests for Diagnosing Back Pain The most common imaging tests to diagnose back problems are: X-ray (radiography). A standard X-ray is a simple test in which an X-ray beam (a form of electromagnetic radiation) is passed through the hip to create a two-dimensional picture of the bones. Your doctor can use X-rays to view:

Direct Arthrography Alternate methods of direct arthrography examinations may also usemagnetic resonance imaging (MRI) or computed tomography (CT) following contrast material injectioninto the joint.An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medicalconditions.he images can then beexamined on a computer monitor, printed or copied to CD. MRI does not use ionizing radiation (x-rays).CT direct arthrography uses the same type of contrast material as conventional direct arthrography andmay be supplemented by air to produce a double contrast CT arthrogram.

Types of Brain Scans Listen. Scans generate images of the brain for the purpose of diagnosing tumors. They take the place of x-rays, which do not show tumors located behind the bones of the skull or spine. The most common scans for diagnosis and follow-up are magnetic resonance imaging (MRI) and computerized tomography (CT).Certain types of brain scans use a special dye, called contrast, to help areas of interest show up better. Contrast dye is usually injected into the body before the scan starts.he most common scans for diagnosis and follow-up are magnetic resonance imaging (MRI) and computerized tomography (CT).

Glossary Types of X-rays and Scans. MRA (Magnetic Resonance Angiography) MRA—a type of magnetic resonance imaging (MRI) study that is obtained with the same scanning machine—uses a strong magnetic field combined with radiofrequency waves to create highly detailed images of blood vessels in the body. (MRA is most often used to examine vessels in the brain, neck, kidneys, and legs.) The resulting scans, which provide information about blood flow and the condition of blood vessel walls, may then be saved on a computer or on film and examined for abnormalities.

The science of medical imaging: SPECT and PET Our new series, the Science of Medical Imaging, examines the technology behind non-invasive methods of creating images of the human body. In this first instalment, we look at two types of emission imaging: positron emission tomography (PET) and single-photon emission computerised tomography (SPECT).

Radiology Radiology is the science that uses medical imaging to diagnose and sometimes also treat diseases within the body. A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography, nuclear medicine including positron emission tomography, and magnetic resonance imaging are used to diagnose and/or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. The acquisition of medical images is usually carried

MRI (magnetic resonance imaging) and MR angiography Types of MRI scanners. 1  Standard MRI: this machine looks like a long cylinder with a narrow tube in the center. You lay on a moveable bed and your whole body slides inside the tube. 2  Short-bore MRI: this machine is similar to the standard, but it’s about half the length.

VT, PT, MT, UT, RT, IWI-C and IWE Ultrasound is often used for testing of steel, aluminum, plastics, composite materials and cast objects. Radiography (RT) Radiography is the method most often used for checking a weld connection or an object of internal errors / indications and volume errors. Radiography can be performed in two different ways, by X-ray with an x-ray tube, or by gamma used by an isotope.

- Radiopharmaceutical. Many imaging studies such as MRI, PET, CT and x-ray, involve the use of imaging agents. Imaging agents are designed to provide more information about internal organs, cellular processes and tumors, as well as normal tissue. They can be used to diagnose disease as well as monitor treatment effects.-ray Imaging Agents: X-ray imaging agents (contrast agents) work with x-ray and CT imaging by increasing the density of tissues (and thus blocking x-ray transmission). They can be administered by mouth, enema, or injection. Barium: Barium is the most common oral contrast agent used in CT.

Mammography Technique and Types There are two main types of mammography: film-screen mammography and digital mammography, also called full-field digital mammography or FFDM. The technique for performing them is the same. What differs is whether the images take the form of photographic films or of digital files recorded directly onto a computer.
