High-resolution computed tomography in intracranial aneurysms.

E J Angtuaco, E F Binet

    Critical Reviews in Diagnostic Imaging
    |January 1, 1986
    PubMed
    Summary

    High-resolution computed tomography (HRCT) is crucial for diagnosing intracranial aneurysms and subarachnoid hemorrhage. This advanced imaging technique aids in precise localization, characterization, and complication assessment, guiding effective treatment strategies.

    Area of Science:

    • Neuroradiology
    • Medical Imaging

    Background:

    • Intracranial aneurysms pose significant risks, including subarachnoid hemorrhage.
    • Accurate diagnosis and characterization are vital for patient management.

    Purpose of the Study:

    • To detail the technique of high-resolution computed tomography (HRCT) for intracranial aneurysms.
    • To highlight the key indications and applications of HRCT in aneurysm diagnosis and management.

    Main Methods:

    • HRCT involves unenhanced and enhanced scans with thin-section reconstructions.
    • Contrast administration includes initial bolus and a repeat dose for detailed imaging.
    • Direct coronal scanning and multiplanar reformatting are utilized.

    Main Results:

    • HRCT effectively determines the presence and location of subarachnoid hemorrhage and aneurysms.
    • The technique allows for identification and characterization of saccular and giant aneurysms.
    • HRCT assesses aneurysm rupture complications and evaluates surgical outcomes.

    Conclusions:

    • High-resolution computed tomography is the preferred imaging modality for suspected subarachnoid hemorrhage and intracranial aneurysms.
    • HRCT provides comprehensive information for diagnosis, characterization, and management planning.
    • This imaging approach is essential for evaluating complications and postoperative status.
