A complete set of images from the head CT of a trauma patient with subdural hematoma (19 images) was captured from a picture archiving and communication system and transmitted wirelessly as an e-mail attachment after being compressed. The images were retrieved, decompressed, and reviewed using ...
A subcutaneous hematoma is present, external to the galea aponeurosis, which crosses the sagittal suture (DOCX 37 kb) Fig. e8.3 Subdural hygroma. Bilateral frontal subdural hygromas. Note that the attenuation of the hygromas is the same as the CSF in the ventricles (DOCX 53 kb) Fig. e...

Using CT, scalp, bone, extra-axial hematomas, and parenchymal injury can be demonstrated. Computed tomography is rapid and easily performed also in monitored patients. It is the most relevant imaging procedure for surgical lesions. Computed tomography is a suitable method to follow the dynamics of...
CT images are viewed with standard brain parenchyma and subdural (W 150–300 HU, L 50–100 HU) window settings in order to visualize the thinner layers of EDH or SDH against the inner margins of the calvarium. Be aware that thin extraaxial hematomas along the inferior portion of the occi...
The Annalise Triage modality includes 12 prior clearances from the Food and Drug Administration (FDA) for unenhanced head CT and chest X-ray, facilitating timely detection of conditions ranging from acute subdural hematoma and tension pneumothorax to pneumoperitoneum...
Computed tomography (CT) of the head is the imaging modality of choice for diagnosing neurocranial traumatic lesions, such as skull fractures, epidural and subdural hematomas, and hemorrhagic contusion. In many Western countries, CT is therefore routinely used to evaluate patients with minor head ...
D. Subdural hematoma A B ? ? ? The answer isCortical Vein Thrombosis Cortical vein thrombosis (CVT) may occurr as a consequence of retrograde extension of cerebral venous thrombosis, or secondarily, to the tearing of the bridging veins caused by acceleration-deceleration and rotational forces in ...
In this chapter the basic classification of hematomas on CT scan is described as well as how to recognize them. The magnificence of the brain unfolds as you go on an odyssey to describe why epidural hematomas are convex and subdural hematomas are crescent shaped like the new moon. The ...
