Imaging method | Accuracy | Sensitivity | Specificity |
---|---|---|---|
Planar | 49/68 (72%) | 4/16 (25%) | 45/52 (87%) |
SPECT | 54/68 (79%) | 9/16 (56%) | 45/52 (87%) |
SPECT/CT | 65/68 (96%) | 16/16 (100%) | 49/52 (94%) |
In 58 patients, 68 hepatic arteriographies and 99mTc-MAA scans with planar imaging, SPECT, and SPECT/CT were performed. Accuracies, sensitivities, and specificities were calculated to evaluate potential additive value of SPECT/CT compared with planar imaging or conventional SPECT. Difference between sensitivity of planar and SPECT/CT was statistically significant (χ2 test, P = 0.03).
