CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well as other conditions involving the skull or sinuses; it used to guide some brain surgery procedures as well. [2] CT scans expose the person getting them to ionizing radiation which has a risk of eventually causing cancer; some ...
However, increased dosage raises the adverse side effects, including the risk of radiation-induced cancer – a four-phase abdominal CT gives the same radiation dose as 300 chest X-rays. [119] Several methods that can reduce the exposure to ionizing radiation during a CT scan exist. [120]
Pneumoencephalography was associated with a wide range of side effects, including headaches and severe vomiting, often lasting well past the procedure. [2] During the study, the patient's entire body would be rotated into different positions in order to allow air to displace the CSF in different areas of the ventricular system and around the brain.
This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computed tomography (CT scan). [4] It is given by mouth, injection into a vein, or into a body cavity. [5] Side effects include vomiting, skin flushing, headache, itchiness, kidney problems, and low blood pressure. [4]
CT scan (computed tomography) of the brain (without any iodinated contrast), is the initial imaging choice because of its high speed, good accessibility in hospitals, high sensitivity in detecting brain injuries or brain diseases, thus helping to triage patients in emergency department in a timely manner and urgent neurosurgical intervention ...
[1] [3] CT scan is the imaging modality of choice as it is widely available, quick, and with minimal risks. [1] However, CT scan can be limited in determining the exact cause of cerebral edema in which cases, CT angiography (CTA), MRI, or digital subtraction angiography (DSA) may be necessary. MRI is particularly useful as it can differentiate ...
CT scan of the brain showing a massive, prior right-sided ischemic stroke from blockage of an artery. Changes on a CT may not be visible early on. [1] Specialty: Neurology, stroke medicine: Symptoms: Inability to move or feel on one side of the body, problems understanding or speaking, dizziness, loss of vision to one side [2] [3] Complications
CT scans of patients with a tension pneumocephalus typically show air that compresses the frontal lobes of the brain, which results in a tented appearance of the brain in the skull known as the Mount Fuji sign. [1] [2] [3] The name is derived from the resemblance of the brain to Mount Fuji in Japan, a volcano
