Diffuse swelling
Diffuse swelling of the brain is also a common imaging finding in encephalitis. It manifests as increased signal intensity on MRI scans and can lead to brain herniation.
Focal lesions
Focal lesions are common in encephalitis and can occur in any part of the brain. They appear as areas of increased or decreased density on CT or MRI scans.
Differential diagnosis: A list of possible explanations for the observed imaging findings, considering various possible causes such as infection, inflammation, tumor, or trauma.
Imaging manifestations can provide valuable information on the prognosis of encephalitis. For example, the presence of cerebral edema or hydrocephalus can indicate a poor prognosis.
Fluid-attenuated inversion recovery (FLAIR)
A MRI sequence that is used to enhance the visualization of cerebrospinal fluid and brain parenchyma. It is particularly useful in the detection of small hemorrhages and microbleeds.
A type of X-ray imaging that uses infrared radiation to penetrate through dense tissues and produce images with higher contrast than conventional X-rays.

Case analysis of imaging manifestations of encephalitis
Case 1: Analysis of MRI imaging manifestations
• MRI Findings: MRI scan of the brain reveals hyperintense signals in the cortex and white matter of the frontal lobe bilaterally. There is also gadolinium enhancement in the meninges.
Definition
Imaging manifestations of encephalitis refer to the changes in the brain that can be observed through medical imaging techniques during the process of encephalitis.
Monitoring treatment rImeasgpingoenxasmeination can be
used to monitor the response to treatment and assess the recovery of brain function. It can help to identify complications such as intracranial hemorrhage or infarction that may occur during the course of encephalitis.
X-ray terminology
要点一
X-ray
要点二
Infrared imaging
A type of electromagnetic radiation that can penetrate through various types of matter, making it useful for visualizing the inside of the body.
要点三
Digital radiography
The use of digital technology to capture and process X-ray images, providing higher image quality and easier storage and transmission compared to traditional film-based radiography.
Enhancement
The process of improving the contrast and visibility of structures on CT images by injecting a contrast medium into the bloodstream.
Attenuation
The reduction in the intensity of X-ray beams as they pass through body tissues. The degree of attenuation is used to create grayscale images on CT scans.

目录
• Overview of imaging manifestations of encephalitis
• English terminology for imaging manifestations of encephalitis
The importance of imaging examination in the
diagnosis of encephalitis
Diagnosis
Prognosis
Imaging examination can help confirm the diagnosis of encephalitis by revealing the location and extent of brain involvement. It can also exclude other diseases that may mimic encephalitis.
CT terminology
Computed tomography (CT)
A diagnostic imaging technique that uses a series of X-ray images taken from different angles to create a three-dimensional image of the body's internal structures.

English terminology for imaging manifestations of encephalitis
MRI terminology
T1-weighted image (T1WI)
A type of MRI scan that detects the amount of longitudinal relaxation time of protons in tissue. It is often used to visualize structures such as bones and cartilage.
T2-weighted image (T2WI)
A type of MRI scan that detects the amount of transverse relaxation time of protons in tissue. It is often used to visualize soft tissues, such as muscles and tendons.
Vasogenic edema Vasogenic edema is a result of damage to the blood-brain barrier and manifests as areas of increased signal intensity on MRI scans. It usually occurs in the white matter of the brain.
Recommendations: Based on the imaging findings and differential diagnosis, the report may include recommendations for further testing, such as lumbar puncture or additional imaging studies, or treatment options, such as medication or hospital admission.
Interpretation of English diagnostic reports
Imaging findings: The results of the imaging tests, including any abnormalities or lesions observed in the brain parenchyma, cerebrospinal fluid spaces, or vasculature.
These CT findings suggest that the encephalitis may be secondary to a vascular event, such as a stroke or vasculitis.
Nursing Implications
Assess for any focal neurologic deficits and maintain a high index of suspicion for seizures or stroke. Monitor vital signs, especially blood pressure.
Case 2: Analysis of CT imaging findings
CT Findings
Interpretation
CT scan of the brain reveals patchy low attenuation areas in the temporal lobes bilaterally, suggestive of edema or infarction.
Classification
Imaging manifestations of encephalitis can be classified as focal and diffuse based on the extent and location of brain involvement.
Common imaging manifestations of encephalitis
Diffuse swelling of the brain is also a common imaging finding in encephalitis. It manifests as increased signal intensity on MRI scans and can lead to brain herniation.
