Overview of Modalities

The variety of exams done in Imaging is extensive and ever-expanding as technology develops newer, less-invasive ways to investigate the human body and repair abnormal conditions. Technology is advancing at an astounding rate, thanks in part to the IT and engineering advances and the pioneers in the field who have made these procedures possible, and who continue to stretch and reach for new, faster, safer ways to care for patients. Not every Imaging department or Radiologist performs or is proficient in every area, and physician specialization had made its way into the Imaging arena. 

Learning Objectives

To provide nursing with brief overview of
imaging modalities:

• Diagnostic Imaging
  
• Interventional Radiology
  
• Non-vascular
  
• Vascular
  
• Computerized Tomography
  
• Ultrasound

Preoperative Readiness

This module will discuss patient preparation for many of the procedures, such as safety concerns and education for the patient on the procedure to be done. Communication between the nursing unit and the Imaging Department will assist with patient safety and preparation. 

Learning Objectives

• State what is necessary for proper patient
  readiness for an imaging exam.
  
• Explain MRI patient preparation.
  
• Describe which modalities use radiation.

Contrast Administration

There are many types of contrast agents used in Imaging. Indications as well as the rationale for contrast use is discussed. Allergic reactions and renal considerations are also highlighted.

Learning Objectives

• Explain why contrast agents are used in
  imaging exams.
  
• Describe the course of action for the patient
  with an allergy to contrast.
  
• Define a contrast allergy and what equipment is necessary in an area giving
  contrast.
  
• Explain the purpose of oral and IV contrasts.

Sedation

Sedation use is common in many procedures, not just the Imaging department. This module discusses what sedation is, why it is used and the patient assessment before administration, with patient teaching in mind. Levels of sedation, scoring methods used and monitoring through the continuum of recovery, as well as common drugs used are discussed. Reversal agent use and precautions are mentioned.

Learning Objectives

• Define procedural/conscious/moderate sedation.
  
• Discuss the indications and precautions for
  administration of sedation.
  
• Differentiate and discuss the continuum of
  sedation and the effects on the patient.
  
• Identify the commonly used drugs used
  during sedation.
  
• List the safety measures taken prior, during and
  after procedural sedation administration.
  
• Your role for the patient receiving procedural
  sedation.
