Abstract |
39 patients with focal hepatic lesions were evaluated
by Tc-RBC liver scan. The diagnosis of focal hepatic
lesions were made by percutaneous needle biopsy,
angiography, surgery, or clinical courses. Thses
diagnoses included 24 cases of hemangioma, 7 hepatomas,
6 rnetastatic disease, 1 abscess, and 1 cyst. 19
hemangiomas showed focal hot activity on delayed static
planar images. 3 small deep seated hemangiomas were
diagnosed by SPECT that would have been missed by
planar images alone. 21arge hemangiomas had no
radioisotope uptake within the lesions on delayed
images and at surgery cavernous hemangioma with
thrombosis, calcification, and fibrosis were found. For
hepatic heman- giomas in our series, the sensitivity
was 91.7% and the specificity was 100%. The remaining
15 patients including hepatomas, metastatic lesions,
cyst and abscess showed cold defect on delayed blood
pool images. It is concluded that" Tc-RBC liver scan
should be the choice of primary diagnostic procecure
for clinically suspected hepatic hemangioma since its
inexpensive, non-invasive, and readly available. |
