CT of the liver
Jump to navigation Jump to search
Choice of modality
For the liver, the initial imaging of choice is generally as follows:
- Ultrasonography of the liver for suspected cirrhosis and/or portal hypertension.
- CT of the liver, often as part of a general abdominal CT, is generally the investigation of choice to look for metastases of recently diagnosed cancers in the abdomen.
- MRI of the liver is indicated in hypervascular lesions that may represent a focal nodular hyperplasia (FNH).
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.
- Hypoattenuating lesions
- If less than 10 mm in diameter they are generally difficult to characterize adequately. 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.
- Large simple cysts (>4 cm) may be followed up ensure stability.
