About The Test
A CT Brain Plain scan is one of the most common, rapid, and essential diagnostic imaging tests performed today. It serves a critical role, especially in emergency medicine, by creating detailed cross-sectional images of the brain, skull, and surrounding tissues. As a non-invasive procedure, its primary advantage is providing vital information quickly without the need for any injections or contrast dye. At Cadabams Diagnostics, we utilize advanced CT technology to give your doctor the clearest possible view of your brain's health, ensuring you receive a prompt and accurate diagnosis.
What is a CT Brain Plain?
A Computed Tomography (CT) scan combines a series of X-ray images taken from different angles around your head and uses sophisticated computer processing to create detailed, layered images. Think of it like looking at individual slices of a loaf of bread without ever having to cut it.
The term "Plain" in CT Brain Plain simply means that the scan is performed without the use of a contrast agent. This is also commonly referred to as a head CT scan without contrast. This type of scan is the standard for many initial evaluations because it excels at showing bone, acute bleeding, and significant structural changes within the brain. You may also hear your doctor refer to this test as an NCCT head scan, which stands for Non-Contrast Computed Tomography of the head.
Types of CT Brain Scans
While this page focuses on the CT Brain Plain, it's helpful to know that another type exists:
- CT Brain Plain (Non-Contrast): This is the standard test discussed here, ideal for emergencies involving trauma and suspected bleeding.
- CT Brain with Contrast: For other diagnostic needs, a contrast dye may be injected into a vein. This material helps to highlight blood vessels, tumors, and areas of inflammation, making them more visible on the scan.
List of Parameters
When a radiologist at Cadabams Diagnostics examines your scan, they are meticulously looking for specific signs that point to a diagnosis. These include:
- Bleeding (Intracranial Hemorrhage/Hematoma): Identifying any bleeding within or around the brain, which appears as bright white areas on the scan.
- Skull Fractures: Detecting any cracks or breaks in the bones of the skull.
- Brain Tissue Damage: Looking for evidence of damage from a recent stroke, which can be either hemorrhagic (caused by a bleed) or ischemic (caused by a blockage).
- Swelling (Edema): Assessing for swelling in the brain tissue, which can result from injury, stroke, or a tumor.
- Structural Shifts: Checking for any shifting or displacement of brain structures, known as "mass effect," which suggests something is exerting pressure.
- Hydrocephalus: Looking for signs of increased fluid and pressure within the ventricles of the brain.
- Obvious Masses: Identifying large brain tumors, abscesses, or other abnormal growths.
Why This Test
Your doctor may recommend this scan to investigate a wide range of urgent symptoms and conditions. It provides the critical answers needed to decide on the next steps for your care. Key reasons include:
- A sudden, severe "thunderclap" headache, which is a classic symptom of a subarachnoid hemorrhage.
- Loss of consciousness, even for a brief period.
- Weakness, numbness, or paralysis, particularly if it's on one side of the body.
- Sudden trouble with vision, speech, or understanding.
- Confusion, disorientation, or sudden changes in personality or behavior.
- After a significant head injury, making it a crucial type of CT scan for head injury to rule out fractures or internal bleeding.
- Evaluation for a suspected stroke.
When and Who Needs to Take a CT Brain Plain?
A doctor may order a CT Brain Plain in a variety of situations, most often when a quick and accurate assessment of the brain is needed.
- Common Scenarios: This scan is a cornerstone of emergency room diagnostics. It is often the first test performed for patients who present with sudden and severe symptoms, such as an intense headache, sudden dizziness, loss of balance, or seizures. It is also the go-to imaging test immediately following a significant accident or head trauma.
- Patient Groups: Individuals who commonly undergo this test include those with a suspected stroke, victims of motor vehicle accidents or falls, and patients experiencing unexplained neurological symptoms that require urgent investigation.

Illnesses Diagnosed with CT Brain Plain
This powerful test is instrumental in diagnosing or ruling out numerous life-threatening conditions. Some of the primary illnesses identified include:
- Hemorrhagic Stroke: Bleeding within the brain tissue.
- Subarachnoid Hemorrhage: Bleeding in the space surrounding the brain.
- Subdural or Epidural Hematoma: Blood clots that form between the skull and the brain, often after a CT scan for head injury.
- Skull Fractures: Breaks in the cranial bones.
- Hydrocephalus: An abnormal buildup of cerebrospinal fluid in the brain.
- Traumatic Brain Injury (TBI): Assessing the immediate damage from trauma.
- Large Brain Tumors or Abscesses: Identifying significant space-occupying lesions.
Preparing for test
One of the major benefits of a CT Brain Plain is that there is typically no special preparation required.
- Clothing: It is best to wear comfortable, loose-fitting clothing for your appointment.
- Metal Objects: You will be asked to remove any metal objects that could interfere with the quality of the images. This includes jewelry, eyeglasses, dentures, hearing aids, and hairpins.
Pre-requisites
- A referral or prescription from a qualified doctor is required to undergo the scan.
- For a plain CT scan of the brain, no fasting is necessary. You can eat and drink normally before your appointment.
Best Time to Take the CT Brain Plain
There is no "best" time to take a CT Brain Plain. The test is performed based on medical urgency. At Cadabams Diagnostics, our CT services are available around the clock to handle emergency cases whenever they arise. For non-urgent, scheduled scans, you can book an appointment at your convenience.
Eligibility
Nearly everyone is eligible for a CT Brain Plain scan. The main exception involves pregnancy.
- If you are pregnant or think you might be, it is absolutely essential to inform your doctor and the CT technologist beforehand. While the radiation dose is low, alternative imaging like an MRI might be considered to avoid any risk to the fetus.
Procedure for Taking a CT Brain Plain
The procedure is simple, fast, and straightforward. Our team at Cadabams Diagnostics will guide you through every step.
- Step 1: You will be asked to lie down on your back on a narrow, motorized examination table.
- Step 2: A special cradle may be gently placed around your head. This helps you remain still during the scan, which is crucial for getting clear images.
- Step 3: The table will then slide slowly into the center of the large, doughnut-shaped CT scanner. As it does, the X-ray tube will rotate around your head. You will likely hear buzzing or whirring sounds from the machine, which is completely normal.
- Step 4: The technologist operates the scanner from an adjacent control room. They can see, hear, and speak to you at all times through an intercom system. You will be asked to hold very still for the short duration of the scan.
- Duration: The entire scanning process typically takes less than 10 minutes, with the actual imaging lasting for just a minute or two.
Caution Before Taking the Test
For your safety and the accuracy of the test, please share the following information with our technologist before your scan:
- Confirm if there is any possibility that you might be pregnant.
- While not critical for a plain scan, it is always good practice to mention any known allergies or if you have had a previous reaction to contrast dye.
- Inform the team about any recent imaging studies you may have undergone.
Test Results
Results and Interpretations
Finding / Observation | Description | General Interpretation / Significance |
---|---|---|
Normal | Brain structures appear symmetric with no evidence of bleeding, mass, or fracture. | No acute intracranial process detected. |
Haemorrhage | Area of bright white on the scan, a sign of fresh blood. | This indicates acute bleeding, which can be caused by trauma, stroke, or a ruptured aneurysm. It requires urgent medical attention. |
Fracture | A visible break or crack in the bones of the skull. | Typically a result of a head injury. The location and type of fracture are important diagnostic details. |
Edema | Darker, less dense-appearing areas indicating swelling of the brain tissue. | Can be a secondary sign of an underlying issue like injury, stroke, or a tumor. |
Mass Effect | Shifting or displacement of normal brain structures from their usual position. | This suggests a space-occupying lesion like a large tumor or a significant bleed is pushing on the brain. |
