ABSTRACT

Introduction: cranial computed tomography without contrast has been become nowadays in the principal imaging modality during initial evaluation of stroke.
Objective: to propose a systematic evaluation of cranial computed tomography, identifying the basic aspects to be analyzed to facilitate its reading and interpretation in emergency settings.
Method: a descriptive trial was carried out, which included a review of consecutive cranial computed tomography examinations in the period between November 2016 and August 2017 in the Statistical Clinical Information System (SICE) of the Alfonso Gumucio Reyes municipal hospital in the municipality of Montero, Santa Cruzde la Sierra, Bolivia. One thousand- nine hundred and twenty-six cranial computed tomography scans were reviewed. In addition, an English-language bibliographic review was performed in the PubMed database with the following terms and syntax: "cerebrovascular accident" AND "cranial computed tomography".
Results: after completing the bibliographic review, the authors identified the main diseases with tomographic repercussion and proposed the present system to evaluate cranial computed tomography images. The letter "A" for the assessment of attenuation, the letter "B" for the description of the bright lesions, and the letter "C" for the evaluation of the cerebral cavities.
Conclusions: an easy-to-memorize ABC system will facilitate decision-making in emergencies as it covers the major diseases encountered by intensive care physicians and emergency physicians and provides sequential guidance on anatomical structures to be investigated as well as their respective alterations.
