CT Scan In Bangalore
What is CT / CAT Scan and LDCT?
How is Chest CT scan useful?
- Examine Abnormalities from Chest X-rays:When abnormalities are detected on chest X-rays, doctors may order a chest CT scan to obtain more detailed and precise images, allowing for a better assessment of the findings.
- Diagnose Chest Diseases and Symptoms:Chest CT scans are essential in helping doctors diagnose the underlying causes of various symptoms related to chest diseases. These symptoms may include cough, shortness of breath, chest pain, or fever.
- Evaluate Tumours in the Chest:Chest CT scans are particularly useful in detecting and assessing the extent of tumours that originate in the chest (such as lung tumours) or tumours that have spread to the chest from other parts of the body (metastases).
- Monitor Tumour Response to Treatment: During cancer treatment, chest CT scans can be used to evaluate whether tumours are responding to the prescribed therapies effectively.
- Assist in Planning Radiation Therapy: Prior to radiation therapy, chest CT scans aid in precise treatment planning by providing detailed images of the tumour’s size, location, and proximity to critical structures.
- Assess Chest Injuries: In cases of chest trauma, CT scans can help doctors evaluate injuries to the chest, including those involving the heart, blood vessels, lungs, ribs, and spine.
Chest CT scans are instrumental in diagnosing and evaluating various lung disorders, like -
- Benign and malignant lung tumours
- Pneumonia (infections of the lung tissue)
- Tuberculosis (an infectious disease affecting the lungs)
- Bronchiectasis and cystic fibrosis (conditions affecting the airways)
- Pleural diseases (inflammation or other conditions of the lung covering)
- Interstitial and chronic lung diseases (including conditions like fibrosis)
- Congenital abnormalities (abnormalities present since birth)
How is Low-Dose CT (LDCT) Scan useful for Lung Cancer Screening?
- Solid nodules: These are dense nodules with different growth rates. When malignant, solid nodules are more likely to be invasive and faster-growing cancers.
- Subsolid nodules: Subsolid nodules are a distinct category comprising non-solid nodules and part-solid nodules. Subsolid nodules have a higher probability of malignancy. They primarily include atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), and minimally invasive adenocarcinoma (MIA).
Key Differences between Low-Dose CT Scans against CT / CAT scans:
- Reduced Radiation: LDCT scans use only a fraction of the radiation dose compared to standard CT scans, making them suitable for repeated or frequent screenings.
- Focus on Low-Density Lung Tissue: LDCT scans are specifically tailored to evaluate nodules in low-density lung tissue, which is important for early lung cancer detection.
- Limited Effectiveness on Other Tissues: While LDCT excels at examining lung tissue, it may not provide the same level of detail when evaluating bones, organs, or other dense tissues.
What is the mechanism of CT / CAT Scan?
- X-ray Source: A CT scan involves an X-ray source that emits a controlled beam of X-rays through the body.
- X-ray Detectors: On the opposite side of the body from the X-ray source, there are detectors that measure the intensity of the X-ray beam after it passes through the body’s tissues.
- Rotating Scanner: The X-ray source and detectors are part of a rotating gantry that revolves around the patient during the scan.
- Cross-sectional Imaging: As the gantry rotates, multiple X-ray beams are projected through the body from different angles. These X-rays are detected by the detectors, and the information is sent to a computer.
- Image Reconstruction: The computer takes the data collected from the detectors and uses sophisticated algorithms to reconstruct cross-sectional images, or “slices,” of the body.
- 3D Image Creation: By stacking these slices together, a 3D image of the targeted area is created, providing detailed information about the internal structures, organs, bones, and tissues.
How to prepare/ come for CT / CAT Scan?
- Fasting information: No need of fasting non-contrast CT. However, if your CT scan involves the use of contrast material, your doctor may advise you not to eat or drink for a few hours before the procedure.
- Clothing: You may be asked to wear loose-fitting, comfortable clothing for the scan. In some cases, you might be provided with a gown to change into, depending on the area being scanned and the facility’s policy.
- Metal Objects: It’s essential to remove any metal objects, such as jewellery, watches, body piercings, or hairpins etc. before the CT scan. Metal can interfere with the imaging process and cause artifacts in the images.
- Medications and Allergies: Inform your doctor about all the medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies. It’s crucial to disclose any allergies, especially if you have a known allergy to contrast material. In such cases, your doctor may prescribe medications (often steroids) to reduce the risk of an allergic reaction.
How CT/CAT Scan works?
- During the CT scan, you will lie on a table that moves through the CT machine, which resembles a large, doughnut-shaped device. The technologist will position you correctly, and the table will move slowly through the machine while acquiring images.
- It’s essential to remain as still as possible during the scan to ensure clear and accurate images. The technologist may give you specific breathing instructions, depending on the area being scanned.
- The actual CT scan usually takes only a few minutes, but the total time spent in the imaging facility may vary depending on preparation and other factors.
NOTE: Be sure to communicate openly with your healthcare team and technologists about any concerns or questions you have, about the procedure. They are there to ensure your safety and comfort throughout the process.
Who Should Consider Lung Cancer Screening?
- Age: Adults aged 50-80 years
- Smoking History: A significant history of smoking, either current smokers or those who have quit within the past 15 years
- High-Risk Population: Individuals with a 20-pack-year smoking history or more
NOTE: These criteria are not inclusive, it varies for each individual. To know if you need CT scan, take our questionnaire and personalise your diagnosis plan.
