Preliminary Diagnosis: Epiglottitis
I. What imaging technique is first-line for this diagnosis?
AP and lateral radiographic views of the soft tissues of the neck
II. Describe the advantages and disadvantages of this technique for diagnosis of epiglottitis.
Advantages
Relatively inexpensive and fast imaging modality
Highly portable and exposes patients to minimal ionizing radiation
High sensitivity for diagnosis
Disadvantages
Poor specificity for diagnosis
Limited in detailing and evaluating the surrounding soft tissues, osseous structures, and vascular structures
III. What are the contraindications for the first-line imaging technique?
No specific contraindications to plain radiography exist.
IV. What alternative imaging techniques are available?
CT imaging
V. Describe the advantages and disadvantages of the alternative techniques for diagnosis of epiglottitis.
CT imaging
Advantages
Highly sensitive and specific in diagnosing epiglottis
Highly adept at characterizing any secondary complication.
More adept than plain radiography in detailing the surrounding soft tissue structures, osseous structures, and vasculature
May help direct any potential treatment and therapy
Disadvantages
Exposure to ionizing radiation
VI. What are the contraindications for the alternative imaging techniques?
CT imaging
May be contraindicated in pregnant patients
