A smoking history can leave you wondering about your lungs long after the last cigarette. Low-dose lung screening near Doral offers eligible adults a way to look for certain small lung abnormalities before symptoms appear.
The examination uses low-dose CT, also called LDCT, to create detailed images of the lungs. It can show small nodules and other visible changes that may not appear on a standard chest X-ray. Finding a nodule does not automatically mean cancer, but it may lead to follow-up based on its size and appearance.
Life Imaging serves Doral residents through our Miami center. We complete the CT examination and provide a report reviewed by a licensed radiologist. Your physician can then explain the findings and determine whether follow-up is appropriate.

Who Qualifies for Low Dose Lung Screening?
Lung cancer screening is not recommended for every adult. National guidelines focus on people whose age and cigarette smoking history place them at higher risk.
The Centers for Disease Control and Prevention states that annual low dose CT screening is recommended for adults who meet all three of the following conditions:
- They are between 50 and 80 years old
- They have at least a 20 pack-year cigarette smoking history
- They currently smoke or quit within the past 15 years
These criteria apply to evidence-based annual lung cancer screening. Individual circumstances can be more complicated, so eligibility should still be discussed with a healthcare professional.
Other exposures, such as secondhand smoke, asbestos, diesel exhaust, silica, or radon, may affect lung health. However, exposure alone does not automatically place someone within the standard screening criteria.
How Is Smoking History Calculated?
A pack-year is a measure of cigarette exposure over time. It combines the number of packs smoked each day with the number of years a person smoked.
For example:
- Smoking one pack per day for 20 years equals 20 pack-years.
- Smoking two packs per day for 10 years also equals 20 pack-years.
- Smoking half a pack per day for 40 years equals 20 pack-years.
Smoking habits often change. You may have smoked heavily during one period and much less during another. If you are unsure of your total, write down the ages when you started and stopped, along with the average amount smoked during each stage.
Your physician or our scheduling team can help you organize this information. Try to provide the most accurate estimate possible rather than rounding up to qualify or rounding down because the history feels uncomfortable.
Why Low Dose CT Is Used for Lung Screening
Low-dose CT can show smaller lung abnormalities than a routine chest X-ray. The scanner collects many images through the chest, allowing a radiologist to examine the lungs in thin sections.
The examination uses less radiation than a standard diagnostic chest CT. It does not usually require contrast material, injections, or sedation.
Research supported by the National Cancer Institute has found that low-dose CT screening can reduce the risk of dying from lung cancer among people at high risk because of heavy smoking.
That benefit does not mean the scan is perfect. Some cancers may be missed, and many findings that require follow-up are not cancer.
What Can Appear on a Lung Screening Scan?
A lung screening CT may show nodules, scars, areas of inflammation, emphysema, or other structural changes. The radiologist considers the size, shape, density, and location of a finding when preparing the report.
Lung Nodules
A lung nodule is a small spot in the lung. Nodules are common, and many are caused by an old infection, inflammation, or scar tissue rather than cancer.
A radiologist may recommend watching a nodule with another CT scan. A larger or more concerning nodule may require closer evaluation by a physician.
Signs of Emphysema
CT images may show visible changes associated with emphysema. The scan does not measure lung function, so breathing tests may still be needed.
Scarring or Previous Inflammation
Old infections and inflammation can leave scars or other changes in lung tissue. These findings may be stable and harmless, but earlier imaging can be useful for comparison.
Findings Outside the Lungs
A chest CT also captures portions of nearby structures. The radiologist may notice an unexpected change involving another visible area. This is called an incidental finding and may lead to a recommendation for further evaluation.
A Lung Nodule Does Not Automatically Mean Cancer
Hearing that a scan found a lung nodule can be unsettling. It is important to pause before assuming the worst.
Many nodules are benign. The next step depends on details such as the nodule’s size, appearance, location, growth, and whether earlier images show that it has remained stable.
Possible recommendations may include:
- No immediate follow-up when the finding has a clearly benign appearance
- Another low dose CT after a specific interval to check for change
- A diagnostic chest CT for more detailed evaluation
- Consultation with a pulmonologist or another specialist
- Additional testing when the finding has concerning features
Life Imaging does not diagnose lung cancer or decide which treatment a patient needs. A licensed radiologist describes the imaging findings, and your physician determines the appropriate next step.
What Happens During a Low Dose Lung CT?
The examination itself is brief. You will lie on a padded CT table, usually with your arms raised above your head. The table moves through a scanner that is open at both ends.
A technologist will speak with you throughout the examination. You may be asked to take a deep breath and hold it for several seconds while the scanner collects images. Holding still helps prevent motion from blurring the pictures.
The scan does not normally involve:
- Contrast material
- Needles
- Sedation
- An enclosed tunnel
- A recovery period
The image collection often takes only a few minutes. Registration and positioning make the full appointment longer, so follow the arrival instructions provided when you schedule.
Preparing for Lung Screening Near Doral
Very little preparation is usually required. You can generally eat, drink, and take your usual medications unless our team tells you otherwise.
Wear comfortable clothing and be prepared to remove jewelry or metal objects near your chest. Tell us if you are pregnant, think you could be pregnant, or recently completed another CT examination.
Bring accurate information about your cigarette smoking history. It is helpful to know:
- The age when you began smoking
- The average number of packs smoked each day
- Any years when you stopped and later restarted
- The year you quit, if you no longer smoke
- Whether you have completed earlier lung CT examinations
Previous images or reports may help a radiologist determine whether a finding is new or unchanged.
Screening Is Different From Diagnostic Lung Imaging
Low dose lung screening is designed for eligible adults who do not have symptoms suggesting an active lung problem.
If you have a persistent cough, cough up blood, develop unexplained weight loss, experience chest pain, or notice worsening shortness of breath, contact a physician. Your doctor may recommend diagnostic testing instead of a routine screening examination.
A diagnostic chest CT may use a different imaging technique or contrast material because it is intended to investigate a specific symptom or known abnormality.
Do not wait for a screening appointment if you have severe breathing difficulty, sudden chest pain, blue lips, confusion, or another possible emergency. Call 911.
Benefits and Limitations of Lung Screening
The benefit of low-dose CT is the ability to identify certain lung cancers at earlier stages in people at high risk. The scan may also establish a useful baseline for later comparison.
Screening has limitations that should be understood before the appointment:
False Positive Results
A scan may show a nodule or another change that looks concerning but is not cancer. Follow-up imaging can clarify many of these findings, although waiting for another result may cause anxiety.
False Negative Results
No test finds every cancer. A scan may appear reassuring even when a small or difficult to see cancer is present.
Overdiagnosis
Screening can occasionally identify a cancer that might never have caused harm during a person’s lifetime. It is not always possible to know which cancers would remain harmless.
Radiation Exposure
Low dose CT uses less radiation than a standard chest CT, but the exposure is not zero. Annual screening creates repeated exposure over time, which is why the test is recommended for people with a meaningful chance of benefit.
Additional Testing
A finding may lead to another CT scan, a PET scan, biopsy, or specialist evaluation. Some follow-up procedures have their own risks.
Screening is a personal decision that should be made with a clear understanding of both the possible benefit and the possible downsides.
When Should Annual Lung Screening Stop?
Current guidelines do not recommend annual low-dose CT forever.
Screening generally stops when a person:
- Reaches the upper age limit in the applicable guideline
- Has not smoked for more than 15 years
- Develops a health condition that substantially limits life expectancy
- Would not be able or willing to undergo treatment if lung cancer were found
Do not cancel an established screening schedule solely because one scan was normal. Likewise, do not continue annual imaging automatically if your health circumstances have changed.
Your physician can help decide whether ongoing screening remains appropriate.

Yes. People who have never smoked can develop lung cancer. Radon, secondhand smoke, occupational exposures, air pollution, family history, and other factors may affect risk. However, current evidence-based screening guidelines are primarily based on age and cigarette smoking history. A physician can evaluate other concerns individually.
The image collection often takes only a few minutes. Registration, changing clothes if necessary, reviewing your history, and positioning on the CT table make the complete visit longer. You will receive arrival instructions when scheduling.
No. A chest X-ray is not considered an equivalent substitute for recommended low dose CT lung cancer screening. CT produces more detailed cross-sectional images and can show smaller lung abnormalities.
A licensed radiologist will describe the nodule and may recommend follow-up based on its size, appearance, and other features. Many nodules are not cancer. Your physician can determine whether you need another CT scan, specialist review, or additional testing.
Some do. Current guidelines include former smokers who meet the age and pack-year requirements and quit within the past 15 years. The exact timing since quitting matters, so provide an accurate date when discussing eligibility.
Not necessarily. A normal result reflects what was visible at the time of that examination. Eligible adults may be advised to continue annual screening as long as they remain within guideline criteria. Discuss the next screening date with your physician.
