A systematic approach to the lungs, airways, pleura, mediastinum, bones, and upper abdomen on noncontrast chest CT, with a normal report example.
A normal chest CT report should include more than the statement “the lungs are clear.” Chest CT covers the lung parenchyma, airways, pleura, mediastinum, assessable aspects of the heart and great vessels, lymph nodes, chest wall, bones, and visible upper abdomen.
Report content varies with protocol. Standard-dose CT, low-dose screening CT, and high-resolution CT should not share an identical template. Noncontrast chest CT is not an appropriate examination for excluding pulmonary embolism, and the report should not make negative vascular claims beyond the protocol.
Clinical safety note: A normal template does not expand the diagnostic scope of the protocol. Do not report a condition as absent when the examination was not designed to assess it.
Review both lungs by lobe and segment from apex to base. Look for focal consolidation, ground-glass opacity, nodule, mass, atelectasis, emphysema, and interstitial change.
The phrase “no pulmonary nodule” requires technically appropriate imaging and careful review of the entire parenchyma.
Assess the trachea and main bronchi for patency, wall abnormality, or endobronchial lesion. Expiratory collapse and small-airway disease may be limited on a routine inspiratory study.
Review for pleural effusion, pneumothorax, pleural thickening, and plaque. Very small effusions may collect in the posterior recesses.
Assess mediastinal and hilar lymph nodes, masses, and fat planes. On noncontrast CT, distinguishing hilar vessels from lymph nodes may be limited.
Heart size, pericardial fluid, and thoracic aortic caliber may be assessed. Luminal disease, dissection, embolism, or vascular-wall pathology requires the appropriate protocol.
Review the axillary nodes, chest-wall soft tissues, and visible thyroid for significant abnormalities. Chest CT does not replace dedicated breast or thyroid imaging.
Review the ribs, sternum, vertebrae, and shoulder girdles on bone windows. Do not overlook fracture, destructive lesions, or relevant degenerative change.
Inspect the visible portions of the liver, spleen, adrenal glands, and kidneys. Partial visualization should not be summarized as a normal abdominal examination.
Technique: Noncontrast CT of the chest was performed with axial images and multiplanar reformations.
Comparison: None available.
Findings: The trachea and central bronchi are patent. No focal consolidation, significant ground-glass opacity, suspicious pulmonary nodule, or mass is identified. No pleural effusion or pneumothorax. No pathologically enlarged mediastinal or hilar lymph node is identified. Heart size is within normal limits. No pericardial effusion. The thoracic aorta is normal in caliber. No significant abnormality is identified in the visualized upper abdomen. No acute or destructive osseous abnormality is identified.
Impression: No significant intrathoracic abnormality on noncontrast chest CT.The phrase “no suspicious pulmonary nodule” should only be used when image quality and reconstruction thickness are suitable.
No focal consolidation, suspicious pulmonary nodule, or mass. The central airways are patent. No pleural or pericardial effusion. No pathologically enlarged mediastinal lymph node.
Impression: No significant intrathoracic abnormality.A short report still requires review of the bones, chest wall, and visible upper abdomen.
High-resolution CT for interstitial lung disease evaluates reticulation, traction bronchiectasis, honeycombing, air trapping, and disease distribution. Inspiratory, expiratory, or prone images must be incorporated when obtained.
A routine noncontrast chest CT template should therefore not be copied directly into an HRCT report.
Contrast-enhanced studies improve evaluation of vessels and mediastinal structures, but timing remains critical. A routine venous-phase chest CT is not equivalent to CT pulmonary angiography.
Lymph nodes, pericardial fluid, aortic caliber, and mediastinal masses require mediastinal-window review.
Pulmonary arterial lumina cannot be reliably assessed without the appropriate contrast-enhanced angiographic protocol.
Important adrenal or hepatic findings may appear on chest CT.
Size, morphology, distribution, and clinical context should be interpreted together.
When image quality or protocol is limited, use a conclusion that accurately defines the scope rather than “no abnormality whatsoever.”
No. Pulmonary embolism assessment requires a properly timed CT pulmonary angiography protocol.
Only when image quality and technique allow a confident assessment. Avoid overly definitive wording in the presence of thick sections, motion, or other limitations.
Clinically significant findings in the visible portions should be reported, while recognizing that partial imaging does not replace a dedicated abdominal examination.
