Computed tomography (CT) of the head revealed acute intracranial abnormalities in 10.8% of patients with nontraumatic headache. This diagnostic imaging is most frequent in inpatients and those over 40.

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Nontraumatic headache is a common presenting complaint in clinical practice.
  • Diagnostic imaging, particularly computed tomography (CT), is frequently utilized for evaluating patients with headache.
  • Determining the diagnostic yield and cost-effectiveness of CT head examinations is crucial for resource allocation and clinical decision-making.

Purpose of the Study:

  • To retrospectively analyze the findings of computed tomography (CT) head examinations in patients presenting with nontraumatic headache.
  • To determine the frequency of acute intracranial abnormalities detected by CT in this patient population.
  • To assess the cost associated with identifying acute intracranial abnormalities via CT head scans.

Main Methods:

  • Retrospective study conducted at two teaching hospitals in the United States and Canada.
  • Analysis of 1111 computed tomography (CT) head examinations performed over a 3-year period.
  • Categorization of findings into acute intracranial, cranial/extracranial, and chronic abnormalities.

    • Main Results:

    • 10.8% of CT head examinations revealed acute intracranial abnormalities (hemorrhage, infarction, tumor).
    • Acute abnormalities were more frequent in inpatients and individuals over 40 years of age.
    • Chronic abnormalities were the most significant findings in 18.2% of cases, with cranial/extracranial abnormalities in 3.6%.

    Conclusions:

    • Computed tomography (CT) of the head is a valuable tool for identifying acute intracranial pathology in patients with nontraumatic headache.
    • The diagnostic yield of CT head for acute abnormalities varies by patient demographics and clinical setting.
    • The cost per identified acute intracranial abnormality warrants consideration in healthcare economics and diagnostic strategies.
