How to Determine the Nature of Lung Nodules/GGO?
Determining the nature of lung nodules or ground-glass opacities (GGO) is a complex process involving various examination and evaluation methods. GGO is commonly seen in conditions such as pneumonia and tuberculosis, while lung nodules typically refer to round shadows with a diameter of 3 centimeters or less. To accurately assess the nature of these lesions, imaging studies, pathological tissue biopsies, and other auxiliary tests are usually required.
1. Imaging Studies: For patients with suspected lung nodules, chest X-rays and CT scans are typically performed. These tests help doctors initially determine the location and morphological characteristics of the lesions. CT scans are particularly important as they provide more detailed images of the lungs, aiding in distinguishing between benign and malignant lesions.
2. Pathological Tissue Biopsy: If imaging studies suggest a suspicion of malignancy, doctors may recommend percutaneous biopsy or bronchoscopy for tissue sampling. These methods allow for the acquisition of lesion tissue samples for pathological examination, thereby confirming the diagnosis. If the lesion is considered benign, doctors may recommend anti-inflammatory treatment and observe its changes.
3. Other Auxiliary Tests: Besides imaging and pathological examinations, blood tests such as complete blood count, C-reactive protein, and procalcitonin levels are also helpful. These tests assess the severity of the condition and prognosis, providing doctors with additional diagnostic information. In clinical practice, doctors comprehensively consider the patient's medical history, symptoms, signs, and laboratory test results, combined with imaging findings, to make a diagnostic conclusion. It is crucial to communicate fully with a professional physician and receive a professional diagnosis and treatment plan.
Through these steps, patients can better understand their health status and receive appropriate treatment recommendations.
