1. Traumatic Brain Injuries. CT scans are commonly used to determine the severity of a traumatic brain injury (TBI) due to a blow or jolt to the head or body. Detailed images from CT scans can show brain bruising, bleeding and swelling following a head injury.
Step 3: Brain. Examine the brain for: Symmetry - make sure sulci and gyri appear the same on both sides. (easiest when patient not rotated in the scanner) Grey-white differentiation - the earliest sign of a CVA on CT scan is the loss of the grey-white interface on CT scan. Compare side to side.
Abnormal results from neurological examination are the best clinical parameters to predict structural intracranial pathology on CT-scan in adult patients experiencing headache disorder. In case of post-traumatic headaches, in addition, otorrhagia, epistaxis, and periorbital ecchymosis are too highly predictive.
A brain lesion is an abnormality seen on a brain-imaging test, such as magnetic resonance imaging (MRI) or computerized tomography (CT). On CT or MRI scans, brain lesions appear as dark or light spots that don't look like normal brain tissue.
Health Library / Symptoms / Brain Lesions. Brain lesions are areas of brain tissue that show damage from injury or disease. The most common way to detect brain lesions is with diagnostic imaging scans. Depending on the cause, some types of brain lesions will heal on their own or are treatable.
Head CT Approach First - evaluate normal anatomical structures, window for optimal brain tissue contrast Second – assess for signs of underlying pathology such as: mass effect, edema, midline shift, hemorrhage, hydrocephalus, subdural or epidural collection/hematoma, or infarction Third – evaluate sinuses and osseous structures
A CT of the brain is a noninvasive diagnostic imaging procedure that uses special X-rays measurements to produce horizontal, or axial, images (often called slices) of the brain.
Abnormal head CT scans can indicate a wide range of medical conditions affecting the head and brain. Learn about the causes, interpretation, and treatment options for abnormal head CT scans in this comprehensive guide.
Diagnose muscle and bone conditions, such as bone tumors and breaks, also called fractures. Show where a tumor, infection or blood clot is. Guide procedures such as surgery, biopsy and radiation therapy. Find and watch the progress of diseases and conditions such as cancer, heart disease, lung nodules and liver masses.
A head CT scan is recommended to help diagnose or monitor the following conditions: Birth (congenital) defect of the head or brain; Brain infection; Brain tumor; Buildup of fluid inside the skull (hydrocephalus) Injury (trauma) to the brain, head, or face; Stroke; Bleeding in or around the brain ; It may also be done to look for the cause of:
