Liver R.B.C. Study

Indication:

• To confirm a suspected haemangioma seen on CT scan.

Principle:

• The patient's red blood cells are labelled with a radiotracer. Haemangiomata are identified as areas of marked RBC pooling.

Preparation and Procedure:

• It is preferable the scan is not done within 4 days of a barium meal or CT contrast of the abdomen.

• Images of the liver are acquired 2 ½ - 3 hours after injection.

Comments:

• Very small lesions (1cm) may not be detected with this technique.

• SPECT/CT is valuable in providing anatomical localisation.
