Normal CT brain of a 35 year old female for reference.

2024年10月16日 · This article lists a series of labeled imaging anatomy cases by body region and modality.

2025年2月8日 · This article lists examples of normal imaging of the brain and surrounding structures, divided by modality and protocol. example 1: C-, perfusion and CTA.

Swelling starts to subside and small amounts of cortical petechial haemorrhages results in elevation of the attenuation of the cortex. This is known as the CT fogging phenomenon cortex can appear near normal on CT. necrosis.

2025年1月1日 · Axial noncontrast CTB shows asymmetrically hyperattenuating right transverse sinus (black arrow) representing cerebral venous thrombosis. Diagnosis: CVT was later confirmed on CT venogram ( Fig. 7 ) which showed thrombus extension to the right internal jugular foremen.

2024年5月15日 · This study compared the accuracy of an artificial intelligence (AI) model (Annalise Enterprise CTB Triage Trauma) to consensus neuroradiologist interpretations in detecting 4 hemorrhage subtypes: acute subdural/epidural hematoma, acute subarachnoid hemorrhage, intra‐axial hemorrhage, and intraventricular hemorrhage.

Axial non-volumetric scanning is how CT began where one (or just a few) slices are acquired during each gantry rotation. Traditional helical scanning (some call spiral) has the advantage of being faster than non volumetric axial scanning and also uses data continuously for improved motion robustness.

• The axial (standard) plane: top to bottom • The coronal plane: front to back • The sagittal plane: ear to ear

2020年7月5日 · Coronal (a) and axial (b) computed tomography angiogram (CTA) images show an embolus occluding nearly all blood flow through the M1 segment of the right middle cerebral artery. Cerebral blood flow (CBF) ( c ), cerebral blood volume (CBV) ( d ), and mean transit time (MTT) ( e ) are displayed qualitatively using a color scale.

Background and objectives: CT of the brain (CTB) is one of the most common radiological investigations performed in the emergency department (ED). Emergency clinicians rely upon this imaging modality to aid diagnosis and guide management. However, their capacity to accurately interpret CTB is unclear.
