X-rays are electromagnetic radiation that penetrates structures differently within the body and creates images of such structures on a photographic film or a fluorescent screen. Such pictures are considered x-rays diagnostic.

Diagnostic x rays are useful for identifying body abnormalities. X- Rays are a painless, non-invasive way of helping to diagnose problems like broken bones, cancers, dental decay, and foreign bodies.

X-rays easily move through the air and soft tissues of the body. They are stopped when they meet denser material, such as a tumor, bone, or a metal fragment. Diagnostic x- rays are done through a painless operation by positioning the body part to be examined between an x-ray focused beam and a film-containing plate

The greater the material density through which the x-rays pass, the more rays are absorbed. Thus, bone absorbs more x-rays than muscle or fat, and tumors can absorb more x-rays than the tissue around.

Magnetic resonance imaging (MRI) makes body structure study with no documented long-term side effects, this allows for broad Coverage, ongoing acquisitions, child studies, and adolescents. Analysis of MRI in the whole body motivated by the need for exact determinations of the phenotype.

Age and race have implications for the body composition; hence, possibly studies of certain factors extensive review of the gain. Larger range, Dense sampling, and repeated takeovers require Data-processing automation.

Its automation Complicated since levels of MRI are given in AUs (Arbitrary Units) and images get affected intensely in homogeneity. The technique, however, wasn’t validated in a contiguous whole body yet the region has not compared results with those of modalities previously validated.

DescriptionX-rayMRI
Exposure of radiationExposure to harmful ionizing radiationNot ionizing radiation emitted by MRI devices
ApplicationsX-rays are mostly used for examination of broken bones. Could be used for identifying diseased tissues, too.Suitable for evaluation of soft tissue such as injury to the ligaments and tendons, injury to the spinal cord, brain tumors etc.
Time taken to complete a scanWithin few secondsThe scan may be quick (finished in 10-15 minutes) or may take a long time (2 hours) depending on what the MRI is looking for, and where it needs to look.
Principle of applicationThe attenuated (blocked) X-rays by denser tissue produce a shadow on the image.Body tissues containing atoms of hydrogen (e.g. in water) are made to emit a radio signal which the scanner detects.
Power to change the imaging plane without the patient movingDoes not have that skillMRI machines are capable of making images in any plane. In addition, 3D isotropic imagery can also produce multiplanar reformation.
Bony structural dataDetailed photographs of bone structure on photographic film as bones absorb x-rays and x-rays impact photographic film in the same manner as lightLess detailed than X-rays
The Body EffectsThe powerful rays are capable of causing birth defects and diseases, and can also alter the DNA.Using MRI no biological hazards were reported. Some may, therefore be allergic to the contrast dye, which is often unsafe for people with kidney or liver disorders.
CostCheap than MRI and CT-scanExpensive
Soft tissue detailsYou can only see bone and other dense tissuesProvides a lot of detail on soft tissue
Application Scope

X-Ray is limited to just examining a couple of body conditions.MRI is more versatile than X-Ray, and is used to investigate a wide range of medical conditions.
Image specificationShows the differences between the soft tissues and bone density.Proves subtle differences between different types of soft tissues.
DetailoredX-ray is not a very detailed examination but rather used to see bones and check for minor infection of the chest / sinus.Although an MRI is good for seeing soft tissue, it is a very specific test however. Therefore when searching for issues of unknown origin it is not a viable option

Pictorial Differences Between MRI And X-Ray Techniques

Methodology Based Differences

MRI uses an oscillating magnetic field is perpendicular to an extremely strong magnetic theory field in which the organ to be scanned is mounted. This oscillating field makes magnetization of the hydrogen atoms within the organ in a direction perpendicular to the magnetic field of principle. MRI also used to diagnose the problems of Knee, joints, and many more like.

  • Brain
  • Breasts
  • Heart
  • Wrist   
  • Vessels in the blood

The fat and water molecules in your body bounce off a constant magnetic field and radio frequencies. In the machine, radio waves are transmitted to a receiver that translated into a body image and used to diagnose problems. MRI is a high-speed machine. Typically, earplugs or headphones will be offered to make the sound more bearable.

X-rays are high-frequency beams (wavelengths between 10 and 0.1 nm) of the electromagnetic spectrum, which can easily pass through low-density material (atomic number) but not through high-density materials. So, in the X-Ray picture, solid objects such as kidney stones and bones come out very obvious.

Functionality Based Differences

X-rays use radiation to give an image of the internal structure of the body. Typically they are used for diagnosing and assessing bone degeneration or disease, fractures and dislocations, infections or tumors.
MRI combines a powerful radio wave magnet (using no radiation) and a computer to create highly detailed images of body structures.

Images are viewed as cross-sections of the body part being scanned, or “slices”. MRI scans are also used to treat issues with the bones and joints.

The differences are premeditated under the headings below in table.
