Liver - Technique

Normal Liver


Technique

• Patient: Fasting 6 hours (so the bowel gas limited & GB is not contracted.)
• Position: Supine, right anterior view (bec liver is tucked beneath the lower right ribs, a transducer with a small scanning face allowing an intercostal approach, is valuable.)
• Breathing: Suspended inspiration (so able to see dome)
• Transducer: Sagittal, transverse, coronal, subcostal oblique

To make the liver more accessible, patients need:

• Raise the right arm above the head (to draw the rib cage upward)
• Supine position
• Deep breath and hold (to expand the abdomen)

Transducer/ Scanning approach:

                              
































Scanning down the left border of liver (TS)


Liver TS scan: Center of liver

*Place the transducer in the epigastrium region to the left of midline, for imaging LF hepatic border*

Liver TS scan: Right lobe

* Hold transducer in a slightly oblique position, parallel to the costal margin *

Step for Liver intercostal scan:

1. Scan through the liver in fan-shaped pattern
2. Slide the transducer along the intercostal space & scan through
3. Move transducer to next intercostal space & scan through
