CT or MRI of the abdomen, which method is better

Today in medicine, an important place is given to the correct diagnosis of a human disease. Symptoms of many diseases are similar, this leads to an erroneous diagnosis, a slowdown in its formulation, and the appointment of improper treatment.

It is possible to identify the cause of the disease and examine the patient’s organs using informative and safe diagnostic methods with magnetic resonance and computed tomography scanners.

None of the methods have particular advantages, each of which is good in its own way and has its own specifics in a certain area of ​​diagnostics. They display a clear picture of the functioning of organs, their pathology.

Computed tomography and magnetic resonance imaging today remain highly informative, modern and significant diagnostic methods. In each individual case, a qualified doctor determines which diagnostic method is best for the patient.

Computed tomography (CT)

CT – a diagnosis that allows you to see the state of tissues and organs. Using a computer, all scanned images are processed and a three-dimensional image of the organ is compiled.

Computed tomography is more effective for detecting solid formations, changes in the density of connective tissues under the influence of a specific disease.

Magnetic Resonance Imaging (MRI)

The principle of operation of the MR tomograph is the same, only it emits electromagnetic waves.

Magnetic resonance imaging is more informative in identifying soft tissue pathology and detecting the inflammatory process of the abdominal cavity.

Common Diagnostics

It is difficult to say which of the two abdominal diagnostics is more effective. This part of the body consists of internal organs of different density, functional activity and configuration, so both diagnostic methods are suitable. What method to use when examining these diseases is determined by the doctor, depending on what is not clear to him in the patient’s condition. These diagnostics do not fully inform about the disease.

They are used together with other examinations in the direction of a specialist. What diagnostics can be more efficiently determined only in each individual case. Computed tomography detects fresh bleeding more clearly and clearly, therefore, with injuries this method is more reliable. Magnetic resonance imaging scanner better determines the localization and size of tumors. Often both of these methods are used comprehensively.

In terms of information, MRI and CT are almost identical.

Difference in Diagnostic Work

Tomographs differ in the principle of operation and impact on the patient’s body. A computer tomograph transmits the body through x-rays of low intensity at a certain point. X-rays are captured by the detector and transmitted to the computer. The body is illuminated by the emitter at predetermined angles, which allows you to take photos of the organ and its sections in different projections and sizes.

The work of a magnetic resonance imager is based on the reaction of the body to electromagnetic radiation, the general condition of a person does not change from this. Scan data is also sent to the computer screen. MRI uses a magnetic field and examines the chemical structure of organs and tissues. CT scans use X-rays and examine the physical state of tissues and organs.

CT diseases detected by CT

With the help of CT, the following diseases are detected:

  • Vessels.
  • Gallbladder.
  • Spleen.
  • The stomach.
  • The liver.
  • Large and small intestines.
  • Pancreas.
  • Spleen.
  • Lymphoid tissue.
  • Urinary system.
  • Adrenal glands.
  • Kidney.

Computed tomography of the abdominal cavity is prescribed for:

  1. Injuries.
  2. Cysts.
  3. Gallstones and kidney stones.
  4. Atherosclerosis.
  5. Cirrhosis and hepatitis of the liver.
  6. Cancerous tumors.

This method of examination of the abdominal cavity is often performed before surgery in order to have an idea of ​​the pathology. Three-dimensional image allows the specialist to identify the slightest malfunction in the functioning of internal organs. Computed tomography is an effective method for detecting a tumor at the initial stage.

The use of this diagnosis is contraindicated in:

  • The presence of prostheses or metal implants.
  • Pregnancy
  • Very heavy menstruation.
  • Mental disorders.
  • Fear of confined space.
  • Allergies to iodine.
  • Active patient mobility due to painful syndrome.
  • The presence of a pacemaker.
  • Body mass in excess of one hundred and thirty kilograms,

as well as resuscitation patients.

MRI detected by internal organs

Types of MRI tomography:

  1. With contrast and without.
  2. Veins and arteries.
  3. Sightseeing.
  4. MR angiography.

To establish the accuracy of the diagnosis and determine the correct treatment for the patient, abdominal MRI is performed.

With the help of MRI tomography, the following are examined:

  • Intestines.
  • The organs of the urinary system.
  • Lymph nodes.
  • Kidneys, adrenal glands.
  • Liver and biliary tract.
  • Spleen.
  • Stomach.
  • Veins and arteries.
  • Soft tissue of the abdominal cavity.
  • Pancreas.

With the help of MRI, pathologies are revealed:

  1. Metastases
  2. Tumors
  3. Circulatory disorders.
  4. Inflammatory, cystic and degenerative processes.
  5. Vascular changes.
  6. Congenital malformations of blood vessels and internal organs.
  7. Stones in the urinary and gall bladder.

This examination method is used to clarify the diagnosis with inaccurate studies of other types of diagnostics, with complications of the disease, to monitor the course of the disease or to monitor the effectiveness of treatment.

MRI has contraindications:

  • The presence in the patient’s body of a pacemaker, fragments, bullets.
  • Body tattoos with paints composed of metal.
  • Mechanical heart valve.
  • 1-3 months of pregnancy.
  • Body weight in excess of one hundred and thirty kilograms.

MR diagnosis using contrast is not recommended for:

  1. An allergic reaction to iodine.
  2. Pregnancy and lactation.
  3. Renal failure.
