Background
Palin radiographs the first line screening tool for thoracic pathology.
The sensitivity of radiographs to identify fat content in the small pulmonary lesions however is limited.
CT and MRI imaging having better special resolution remains the gold standard for classification of the abnormality identified on plain films. Multiplanar CT is the most frequently utilized modality. Typical fat attenuation is measured in the range of −40 to −120 HU on CT images.1
Variety of fat containing pathologies are seen in adult thoracic imaging. These lesions are classified based on the location and imaging features.
(Fig 1).
It is important to differentiate benign lesions from the malignant pathology in order to avoid unnecessary follow up imaging or intervention.
