Diagnostic chest CT with or without contrast; PET/CT may be considered if there is a ≥ 8 mm solid nodule or solid component; tissue sampling; and/or referral for further clinical evaluation
21 Ιουν 2022 · Though MRI has several advantages over CT, such as higher soft-tissue contrast and capability to perform dynamic imaging of lesion displacement in relation to respiratory motion, in its current state it is unlikely to replace CT in detecting pulmonary nodules.
CT is significantly more sensitive than standard radiography for nodule detection, and with the increasing use of MDCT, small nodules less than 1 cm are detected with increasing frequency. As a result, small benign lesions that would otherwise have been invisible on radiographs are now detected.
Computed tomography (CT) is the current gold standard for the detection of pulmonary nodules but has high radiation burden. In contrast, many radiologists tried to use magnetic resonance imaging (MRI) to replace CT because MRI has no radiation burden associated.
1 Αυγ 2023 · Most small nodules (6–8 mm) can be managed by conducting periodic CT surveillance per guideline recommendations. Lesions >30 mm that lack benign features may be resected without biopsy because they have such a high likelihood of malignancy that the benefit of resection outweighs the associated risk of surgery.
14 Μαρ 2024 · Pulmonary nodules are small, rounded opacities within the pulmonary interstitium. Pulmonary nodules are common and, as the spatial resolution of CT scanners has increased, detection of smaller and smaller nodules has occurred, which are more often an incidental finding.
20 Φεβ 2014 · With adjustments in image acquisition and postprocessing, contrast-enhanced CT and MRI, especially the dynamic versions, can have enhanced clinical application for pulmonary nodules and expanded clinical relevance for other thoracic diseases.
