Cranial Computed Tomography for Nontrauma Patients: Critical Appraisal of a Decision Rule

A clinical decision rule for cranial computed tomography in minor pediatric head trauma.

OBJECTIVES To develop a sensitive clinical decision rule with a high negative predictive value for the use of cranial computed tomography (CT) in minor pediatric head trauma, to identify clinical features predictive of neurosurgical intervention, and to assess clinicians' predictive abilities to determine the presence or absence of intracranial injury based on history and physical examination a...

Independent emergency physician decision on patients undergoing Cranial computed tomography, a prospective cohort study

Cranial computed tomography of malignant melanoma.

Two hundred seventy-five cranial computed tomography (CT) scans performed on 179 patients with malignant melanoma were reviewed. Of the 101 patients with confirmed cerebral metastases, CT demonstrated lesions in 93. In 72% of these, areas of increased attenuation were present in the precontrast scan. These lesions also enhanced after contrast infusion. There was a direct correlation between the...

Critical appraisal of clinical studies: an example from computed tomography screening for lung cancer.
