Abstract
|
|
|
We evaluated the role of three-headed single-photon emission computed tomography (SPECT) in 99mTc-RBC scintigraphy for the diagnosis of cavernous hemangioma of the liver.
A total of 76 patietns, including 55 patients with 62 hemangiomas and 21 patietns with 27 nonhemangiomas (20 hepatocellular carcinomas, 5 hepatic metastases, 2 other benign lesions), underwent planar RBC imaging followed by glood-poool SPECT
scanning.
The sensitivity of RBC scintigraphy for detecting hemangiomas was improed with the addition of SPECT; from 0% to 16.7% for hemangiomas smaller than 1. 0 cm in diameter (n=6). from 20.0% to 76.0% for lesions betwen 1.0~1.9 cm (n=25). from 64.3% to
100%
for lesions between 2.0~2.9 cm (n=14), and from 94.1% to 100% for lesions≥3.0 cm 9n=17). None of 27 non-hemangiomas showed increase in delayed blood-pool with either planar or SPECT image.
In conclusion, 99mTc-RBC scintigraphy is highly specific in the diagnosis of hepatic hemangiomas and, with the addition of three-headed SPECT, the sensitivity of RBC scintigraphy for the detection of small hemangiomas is considerably improved.
