The Importance of Radiological Diagnostics in Thoracic Oncology

<jats:p>Radiological diagnostics is a key component of contemporary thoracic oncology, enabling early detection of malignant lesions, morphological characterization, disease staging, treatment planning, and monitoring of therapeutic response. Chest radiography is often the first imaging method used to detect suspicious intrathoracic abnormalities, whereas multidetector computed tomography (MDCT) has a central role in the assessment of pulmonary, pleural, and mediastinal tumors. MDCT enables detailed evaluation of tumor size, structure, local extent, lymphadenopathy, and distant metastatic disease. Radiological Tumor-Node-Metastasis (TNM) staging directly influences therapeutic strategy, assessment of resectability, and prognosis. Positron emission tomography/computed tomography (PET/CT) improves detection of mediastinal and distant metastases and helps differentiate active tumor disease from post-treatment changes. Magnetic resonance imaging (MRI) has particular value in assessing neural, vascular, mediastinal, and vertebral invasion, especially in lung apex tumors and complex thoracic masses. The development of radiomics and artificial intelligence further expands the role of radiology through quantitative imaging biomarkers associated with tumor biology, therapeutic response, and prognosis. The integration of radiological, histopathological, and molecular data forms the basis of personalized thoracic oncology.</jats:p>
