MRI Imaging

In anatomy and physiology, the body planes and sections (anatomical planes) determine the various ways in which the body can be viewed when cut into sections.


Healthcare professionals use many types of equipment to diagnose patients. Radiologic technologists, also known as radiographers, specialize in x-ray and computed tomography (CT) imaging. Some radiologic technologists prepare a mixture for the patient to drink that allows soft tissue to be viewed on the images that the radiologist reviews. Further, radiologic technologists might also specialize in mammography, using low-dose x-ray systems to produce images of the breast. Technologists may be certified in multiple specialties.

MRI technologists, on the other hand, operate magnetic resonance imaging (MRI) scanners to create diagnostic images on special film. They must inject patients with contrast dyes so that the images will show up on the scan. The scanning equipment uses overlapping magnetic fields in combination with a contrast agent, in order to produce images that a physician can use to diagnose medical problems.

  • Adjust and maintain imaging equipment.
  • Precisely follow orders from physicians on what areas of the body to image.
  • Prepare patients for procedures, including taking a medical history and answering questions about the procedure.
  • Protect the patient by shielding exposed areas that do not need to be imaged.
  • Position the patient and the equipment in order to get the correct image.
  • Operate the computerized equipment to take the images.
  • Work with physicians to evaluate the images and to determine whether additional images need to be taken.
  • Keep detailed patient records.

MRI scanning provides detailed pictures of the body without ionizing radiation. During this procedure, the patient is placed within a large magnet and radio waves are passed through the body, providing information about that part of the body to the computer, which, in turn displays the image. Computer-generated images clearly show diseased tissue in the brain, spine, and joints. The GE Signa HDe 1.5 8-channel MRI system’s imaging technology delivers reliable high-definition images. The system has advantages over lower strength magnets in that it has the potential of quickly producing a series of well-defined images.

MRI technologists operate magnetic resonance imaging (MRI) scanners to create diagnostic images, whereas radiologic technologists perform diagnostic medical imaging using x-rays. Nuclear medicine technologists prepare radioactive drugs and administer them to patients. The radioactive dye cause abnormal areas of the body to appear stand out from unaffected areas in the images. An associate's degree is the minimum requirement for radiologic and MRI technologists. In addition, you may pursue a graduate certificate or bachelors degree. Training programs include both classroom study and clinical work. Courses include anatomy, pathology, patient care, radiation physics and protection, and image evaluation.


Radiologic technologists and MRI technologists typically need an associate's degree. Many MRI technologists start out as radiologic technologists and specialize later in their career. Radiologic technologists must be licensed or certified in most states, whereas fewer states license MRI technologists. The Joint Review Committee on Education in Radiologic Technology (JRCERT) accredits programs in radiography.

Employers typically require or prefer prospective technologists to be certified even if the state does not require it. Education programs typically include both classroom study and clinical work. Coursework includes anatomy, pathology, patient care, radiation physics and protection, and image evaluation.


Radiologic technologists must be licensed or certified in most states. Few states license MRI technologists. Requirements vary by state. To become licensed, technologists must usually graduate from an accredited program, and pass a certification exam from the state or obtain a certification from a certifying body. Certifications for radiologic technologists are available from the American Registry of Radiologic Technologists (ARRT). Certifications for MRI technologists are available from the ARRT and from the American Registry of Magnetic Resonance Imaging Technologists (ARMRIT). For specific licensure requirements for radiologic technologists and MRI technologists, contact the state's health board.

The mission of the American Registry of Magnetic Resonance Imaging Technologists (ARMRIT) is to recognize individuals qualified as specialists in the use of Magnetic Resonance Imaging Technology which employs non-ionizing radiation to promote high standards of patient care and safety in the diagnostic medical imaging modality of Magnetic Resonance Imaging Technology including interventional MRI, cardiovascular MRI, functional MRI, and MRI breast imaging. The Registry is open to all qualified technologists in all imaging fields provided a formal education has been completed through bonafide established schools dedicated to MRI technologists.


Ask yourself if you can see yourself being a MRI Tech, having daily contact with patients who may be elderly, ill, or recovering from surgery. Other patients may have physical or emotional disabilities, which can be challenging. While nursing classes and internships will prepare you well, certain innate qualities that you bring to bear will help you succeed.

Qualities for Success
Radiologic and MRI technologists work closely with patients who may be in extreme pain or mentally stressed. They must put the patient at ease to get usable images.
Radiologic and MRI technologists may need to calculate and mix the right doses of chemicals used in imaging procedures.
Radiologic and MRI technologists must understand how to operate complex machinery.
Radiologic and MRI technologists must follow exact instructions to get the images needed for diagnoses.
Radiologic and MRI technologists often work on their feet for long periods during their shift and they must lift and move patients who need assistance.

Blood Flow in the Heart

When learning the blood flow of the heart, it helps to divide it up into two sections: The left side and the right side. There are six structures on each of these sides that are used during blood circulation. The left side receives blood that left the lungs. The right side sends blood right to the lungs. In addition, the tricuspid is on the right side, and the bicuspid is on the left side.

EKG/ECG Interpretation

As a nurse, you'll want to be familiar with basic ekg/ecg interpretations, how to identify heart rhythms, P waves, T waves, PR intervasl, QRS complexes, PR segments, ST segments, J point, QT intervals, and so forth. In this video, Nurse Sarah breaks down EKG basics and gives examples of how to measure different parts of a 6-second EKG strip.

Blood Groups (ABO), Rh Factor

There are 8 total blood types from four blood groups (A, B, AB, O). In nursing we transfuse blood, but before we do this we have to collect blood from the patient who will be receiving the blood transfusion. The patient's blood will be typed and crossmatched with a donor. The donor’s blood must be compatible with our patient to prevent a transfusion reaction.

Hypertension NCLEX Review

Hypertension is the amount of resistance of blood pumping through the body/arteries. It affects organ systems of the body such as the cardiovascular, brain, kidneys, and eyes. A normal blood pressure is less than 120/80 (systolic blood pressure/diastolic pressure). Nursing interventions include assessing hypertension risk factors, obtaining blood pressure readings, evaluating medication compliance, and monitoring for side effects of pharmacological medications used for hypertension.


Most radiologic and MRI technologists work full time. Because imaging is sometimes needed in emergency situations, some technologists work evenings, weekends, or overnight. Radiologic and MRI technologists are often on their feet for long periods and may need to lift or turn patients who are disabled. Like other healthcare workers, radiologic and MRI technologists may be exposed to infectious diseases.

In addition, because radiologic technologists work with imaging equipment that uses radiation, they must wear badges that measure radiation levels in the radiation area. Detailed records are kept on their cumulative lifetime dose. Although radiation hazards exist in this occupation, they are minimized by the use of protective lead aprons, gloves, and other shielding devices, and by badges that monitor exposure to radiation.
