Introduction

Under normal circumstances, brain CT refers to a computed tomography (CT) scan of the head. A brain CT scan may detect conditions such as cerebral infarction, traumatic brain injury, basilar skull fracture, cerebral parasitic disease, and brain tumors. If you experience any discomfort, it is recommended to seek medical attention immediately and receive symptomatic treatment under the guidance of a qualified physician. Additionally, maintaining a healthy lifestyle, including a balanced diet and appropriate exercise, can help prevent cerebrovascular diseases.

Generally speaking, brain CT refers to a computed tomography (CT) scan of the head. A brain CT scan may detect conditions such as cerebral infarction, traumatic brain injury, basilar skull fracture, cerebral parasitic disease, and brain tumors. If experiencing any discomfort, it is recommended to seek medical attention immediately and undergo symptomatic treatment under the guidance of a qualified physician. Detailed explanations are as follows:

1. Cerebral Infarction

Cerebral infarction refers to softening and necrosis of localized brain tissue due to impaired blood circulation, which may cause symptoms such as headache, dizziness, and vertigo. Brain CT scanning can reveal the cerebral infarction lesion in the affected cerebral hemisphere.

2. Traumatic Brain Injury

Traumatic brain injury refers to head injuries caused by external forces. Brain CT scanning can clearly display abnormalities such as skull fractures, epidural hematoma, and subdural hematoma, assisting physicians in determining the type and severity of the injury.

3. Basilar Skull Fracture

A basilar skull fracture refers to a break in the bones at the base of the skull, which may be accompanied by symptoms such as cerebrospinal fluid leakage and intracranial infection. Brain CT scanning can accurately show the location and morphology of the fracture, helping physicians assess the type and severity of the fracture.

4. Cerebral Parasitic Disease

Cerebral parasitic disease refers to diseases caused by parasites infecting the brain, often presenting as multiple intracranial calcifications or large cysts. Brain CT scanning can reveal multiple intracranial calcified lesions or cysts, with images of parasites or calcification points visible inside the cysts.

5. Brain Tumor

A brain tumor refers to neoplastic lesions within the cranial cavity, including both benign and malignant tumors. Brain CT scanning can detect most tumors and helps physicians determine the location, size, and shape of the tumor, providing reference information for developing treatment plans.

Maintaining a healthy lifestyle, balanced diet, and moderate physical activity in daily life can help prevent cerebrovascular diseases.

What diseases can be detected by a CT scan of the stomach?

In general, gastric CT is an imaging examination method. Gastric CT can detect diseases such as gastric ulcers, gastric polyps, gastric adenomas, gastrointestinal stromal tumors, and gastric cancer. Gastric ulcers are usually caused by long-term consumption of spicy or irritating foods or infection with Helicobacter pylori. They lead to papillary protrusions on the gastric mucosa and may cause symptoms such as acid reflux or heartburn.
