Low-dose spiral CT is an imaging test that is often used for early lung cancer screening during physical examinations due to its low radiation exposure.
Low-dose spiral CT is an imaging test that can diagnose lesions with a lower radiation dose than conventional CT. Compared to conventional CT, the amount of radiation is greatly reduced, while tiny nodules in the lungs can still be clearly visualized. Therefore, it is often used for early lung cancer screening during physical examinations.
For patients who need frequent follow-ups to track certain lesions, low-dose spiral CT can also be used to reduce the amount of radiation to which the patient is exposed, provided that the lesions can be clearly visualized. Whether to receive conventional CT or low-dose spiral CT, you need to choose under the guidance of doctors in regular hospitals, and do not blindly pursue low-dose and miss the best time for diagnosis.
