Analysis

Focal changes: Scroll through the entire parenchyma, preferably in segments, such as right third, middle third and left third, in order to have greater focus on small details.

Potential findings

  • Hypoattenuating lesions
  • If less than 10 mm in diameter they are generally difficult to characterize adequately.[1] Even in a patient with known malignancy, and with multiple lesions of this size, their presence does not increase the risk of developing liver metastasis, and should practically be regarded as benign.[2]
  • Large simple cysts (>4 cm) may be followed up ensure stability.[3]
