Low Dose CT Chest (LDCT) PTP

<p>Currently, lung cancer screening can be done using low-dose computed tomography (LDCT), which is a three-dimensional imaging method that provides higher resolution than regular X-rays.</p>
<p>&nbsp;</p>
<p>Clinical studies have found that annual LDCT screening for early-stage lung cancer can reduce lung cancer mortality by as much as 20-30%* in high-risk individuals. Early detection of lung cancer before symptoms appear allows for prompt treatment and effective outcomes, with patients receiving a lower radiation dose compared to standard computed tomography (CT) chest scans.</p>

<h3><span style="color: #00826a"><strong>Getting to Know Low Dose CT Chest (LDCT)</strong></span></h3>
<p>Low Dose CT Chest is a low-radiation computed tomography scan of the chest area that produces 3D images with good detail of the lungs. Even with a low radiation dose and without the need for contrast injection, it can effectively detect small spots or nodules in the lungs.</p>
<p>&nbsp;</p>
<h2><span style="color: #00826a">Comparison of Radiation Dose from Different Types of Scans</span></h2>
<ul>
<li>Standard CT chest 7 mSv</li>
<li>Low dose CT chest 1.5 mSv</li>
<li>Chest X-ray 0.1 mSv</li>
</ul>
<p>&nbsp;</p>
<h2><span style="color: #00826a">Why Choose Low Dose CT</span></h2>
<ul>
<li>Provides three-dimensional images with better detail than 2D chest X-rays</li>
<li>Uses about 5 times less radiation than standard CT Chest (Standard CT chest uses 7 mSv* while LDCT Chest uses 1.5 mSv*)</li>
<li>Easy to perform, takes a short time, and has minimal side effects</li>
<li>Can detect small spots or nodules in the lungs without the need for contrast injection</li>
</ul>
<p>&nbsp;</p>
<h2><span style="color: #00826a"><strong>Preparation and Procedure</strong></span></h2>
<ul>
<li>No need to fast or avoid drinking</li>
<li>Change into a gown and lie on the examination bed inside the machine</li>
<li>Hold your breath during the scan for about 15-20 seconds</li>
<li>The scan takes approximately 5-10 minutes</li>
</ul>
<p>&nbsp;</p>
<h2><span style="color: #00826a">Interpretation of Results</span></h2>
<p>After the scan, a radiologist will review the images for abnormalities or the likelihood of malignancy. If there is a high chance of malignancy, further tests such as PET/CT, bronchoscopy, and biopsy may be recommended for rapid diagnosis. If the likelihood is low, continuous monitoring as advised by the physician is recommended.</p>
<p>&nbsp;</p>
<h2><span style="color: #00826a">Important Information About Low Dose CT Chest Results</span></h2>
<ul>
<li>An “abnormal” result does not confirm cancer 100%. The physician will inform the patient and provide appropriate advice.</li>
<li>Current results cannot guarantee that the detected abnormality will not develop into lung cancer or that new abnormalities will not appear in the future.</li>
<li>Follow-up examinations may be necessary as recommended by the physician.</li>
<li>Even if the current result is “normal,” high-risk individuals are advised to continue LDCT chest screening every 1-2 years.</li>
</ul>
