Use of 64-Slice Spiral CT Examinations for Hepatocellular Carcinoma (DR LU)

To evaluate the application value of conventional ultrasound (US) and 64-slice spiral computed tomography (CT) examinations in the clinical diagnosis of hepatocellular carcinoma (HCC) and focal nodular hyperplasia (FNH) of the liver.

A total of 85 patients diagnosed with space-occupying liver diseases via needle biopsy or pathological examination underwent conventional US and CT examinations. The detection of tumor in different sizes was compared, and imaging characteristics were analyzed.

Under the CT enhancement scan, HCC lesions displayed the "fast-in and fast-out" features and the blood flow in the tumor could be clearly showed, while FNH displayed the low/uniform density and significant enhancement. The accuracy of conventional US and CT in the diagnosis of benign liver lesion was 86.00% (43/50) and 94.00% (47/50), respectively, showing no significant difference (p>0.05). However, the accuracy of CT in the diagnosis of malignant HCC was 94.29% (33/35), which was higher than that of US [74.29% (26/35)]. The accuracy of CT in the diagnosis of lesion with a diameter ≤1 cm was 84.00% (21/25), which was higher than that of US [56.00% (14/25)].

The diagnosis and differential diagnosis of HCC and FNH via 64-slice spiral CT are superior to those of conventional US, and the diagnostic effect of CT on tiny lesion with a diameter ≤1 cm is significant.
