Question Answer What are the key imaging features to differentiate between benign and malignant pulmonary nodules in thoracic radiology? Benign nodules often have smooth, well-defined margins, lack of growth over time, and may show calcifications with characteristic patterns such as popcorn or concentric. Malignant nodules tend to have spiculated or irregular borders, increased size over serial scans, and may present with associated features like lymphadenopathy or invasion into adjacent structures. How can chest CT help in the diagnosis of pulmonary embolism (PE)? Chest CT angiography is the gold standard for PE detection, revealing filling defects within the pulmonary arteries. It can also assess for right heart strain, alternative diagnoses like pneumonia or malignancy, and evaluate the extent of emboli, aiding in prompt management decisions. What are the typical radiographic signs of interstitial lung disease (ILD) on high-resolution CT (HRCT)? Key HRCT features include reticular opacities, ground-glass abnormalities, honeycombing, and traction bronchiectasis, often distributed in a basal and peripheral pattern. Recognizing these patterns helps narrow down specific ILD subtypes and guides treatment. In thoracic imaging, what role does PET-CT play in the evaluation of lung cancer? PET-CT combines metabolic and anatomical imaging, aiding in staging by detecting regional and distant metastases, differentiating benign from malignant lesions, and assessing treatment response. It is especially valuable in determining the malignancy potential of indeterminate nodules. What are common radiologic findings suggestive of COVID-19 pneumonia in thoracic imaging? Typical findings include bilateral ground-glass opacities, often with peripheral and posterior distribution, consolidations in more advanced stages, and a crazy-paving pattern. Recognizing these features assists in diagnosis and monitoring disease progression. How can radiologists distinguish between different causes of mediastinal masses on imaging? Evaluation involves assessing location (anterior, middle, posterior mediastinum), shape, borders, and tissue characteristics, along with associated features. For instance, thymomas are anterior and well-circumscribed, neurogenic tumors are posterior, and lymphadenopathy appears as enlarged nodes. Combining these clues aids in narrowing differential diagnoses.
