A CT scan is an advanced X-ray technique that uses X-ray and computer technology to obtain cross-sectional images of the body, giving detailed information for diagnosis.
Computed Tomography (CT Scan)
Common uses of CT Scan:
- Study of the head and neck, chest, abdomen and pelvis as well as the skeleton.
- Diagnosis of cancers, such as lung, liver and pancreatic cancers; to confirm or exclude the presence of tumour, evaluate its size and location.
- Identification of injuries to internal organs in case of trauma.
- A significant role in the detection and diagnosis of cardio-vascular diseases.
Preparations for CT Scan:
- 4-6 hrs fasting is required for CT Angiography with Calcium Score, CT Scan of Neck, Thorax, Abdomen and Pelvis.
- No special preparation of food restriction is required.
- A contrast medium may be administered to highlight relevant areas. Depending on the region to be scanned, you may be given oral contrast or intravenous contrast.
- Inform the radiographer if you suffer from diabetes, mellitus, asthma, heart condition, kidney problems and any drug allergies.
CT Lung Scan
WHAT? The CT Lung scan checks for abnormalities such as tumours and nodules. It is able to detect very small nodules in the lung and is especially effective for diagnosing lung cancer at its earliest, most curable stage. It is also helpful in the evaluation of other lung diseases, blood clots and damage caused by smoking. Don’t worry, it’s non-invasive and painless!
WHO? Recommended for smokers, ex-smokers, those with a family history of lung cancer, and high exposure to outdoor air pollution such as diesel engine exhaust.
WHY? This scan allows doctors to get a closer look at the state of your lungs and be able to identify any diseased or inflamed portions that will require further medical attention. Early identification of cancer will allow you a higher chance of arresting the disease. Better yet, there will be a greater possibility of a complete recovery!
CT Coronary Angiogram
WHAT? A CT Coronary Angiogram is a heart imaging test that screens your heart and blood vessels. It can detect Coronary Artery Disease – blocked or narrowed arteries in the heart caused by buildup of cholesterol and fatty deposits (called plaques) on the inner walls of the arteries. Once these plaques clog the arteries, it can restrict blood flow to the heart muscle. If the blood supply to a portion of the muscle becomes cut off entirely, the heart needs to work harder, which may result in a greater risk of heart attack.
WHO? As smoking damages the lining of the arteries, smokers, couch potatoes and those who tend to have an unbalanced diet high in sugar and fats are at high risk for coronary heart disease.
WHY? The CT Coronary Angiogram will allow early detection of possible issues that will affect the heart negatively, such as Heart Attack
