Broca's area is closely related to Wernicke's area. It, too, works with spoken language and was actually discovered before Wernicke's area. Both of these areas are found on the same side of the brain, usually the left.
Intravenous dye may be used in some imaging procedures (e.g., CT scan, MRI scan). Contrast dye is not used in all cases.Although rare, some patients suffer allergic reactions to the dye and newer contrast agents are quite expensive.he primary risk of a CT scan is radiation. If intravenous contrast is used, there is a risk for allergic reaction as well. Overall, the risks of CT are small.
Pr. Mirjan M. Nadrljanski et al. Computed tomography (CT) scanning, also known as computerized axial tomography (CAT) scanning, is a diagnostic imaging procedure that uses X-rays in order to present cross-sectional images (slices) of the body.n the specific case of the CT, the emitter of X-rays rotates around the patient and the detector, placed in diametrically opposite side, picks up the image of a body section (beam and detector move in synchrony). Unlike X-ray radiography, the detectors of the CT scanner does not produce an image.
