Unlike conventional CT, the new 64-slice spiral CT allows tests with essentially three-dimensional representations of anatomical structures using color codes. The acquisition is done in seconds so as to ensure, even in patients less cooperative, the execution of tests with the patient awake or under simple sedation, reserving general anesthesia only in aggressive patients or those requiring invasive procedures, such as CT guided deep biopsy. The acquisition through the large matrix (1024×1024) allows high spatial resolution. The speed of the device, which allows you to capture packets over a meter and a half in length with a window view of 53 cm in diameter, makes it possible for total-body examinations in all patients, thus ensuring ease of extension and in the staging of diffuse lesions, as well as in finding unsuspected lesions on the basis of clinical data, such as in the case of neoplastic disease. The acquisition through isotropic voxel, or with equal dimensions on all three axes, equal to 600 microns, then allows three-dimensional representations according to any arbitrary plane, thereby allowing to represent admirably anatomical reality and the passage between normality and pathology.

The characteristics above considerably extend the multi-slice CT field of application, allowinginteresting studies in exotic patients, notoriously more complex to manage from the anesthetic point of view and sometimes of very small dimensions. Regarding the characteristics of this equipment, the fusion with the images obtained by means of Magnetic Resonance, possible because both use last generation DICOM language, guarantees very high resolution of spatial tipical bone of the CT and of contrast in soft tissues, typical of Magnetic Resonance.
