Vocal Cord Paralysis. Discussion Consistent with our. A brain scan after a head trauma is nearly always done without contrast, because bleeding also shows up white on the scan. As part of our ongoing UW Madison CT protocol optimization, we have made the following changes between the Revision 2 and Revision 3 release. For follow-up, use CT Abdomen and Pelvis w iv contrast. The Brainlab registration matrix with integrated MR markers is designed for use with a 3-pin skull clamp and therefore does not compromise standard patient positioning. The author concludes that CS radiography is a time-consuming process, often requiring repeated radiographs. The clinical scales in this section are used to evaluate a stroke patient after an acute stroke. If the CT scan is normal, we often recommend a Brain MRI with diffusion imaging, our most sensitive technique for detecting acute stroke. 3, Mastoid process. Condyle cortex, marrow Articular disk position Sagittal T2 closed: Joint effusion Coronal T1 closed: condyle + medial -lateral displacement of articular disk Contrast only if evaluating neoplasm. Computed tomography angiography (CTA) uses an injection of contrast material into your blood vessels and CT scanning to help diagnose and evaluate blood vessel disease or related conditions, such as aneurysms or blockages. 1, Condylar process of mandible.
