To determine the value of spiral CT during arterial portography (SCTAP) in detecting and localising focal liver lesions we compared the SCTAP findings to those gained by conventional CT during arterial portography (CTAP).
We evaluated a total of CT scans of 128 patients with 162 malignant lesions of the liver. 45 patients underwent SCTAP and 83 patients CTAP. Results of radiological studies were compared with surgical and pathological findings.
The overall sensitivity of SCTAP was 93% with a sensitivity of 80% for lesions of less than 1 cm diameter. For CTAP the overall sensitivity was 88%, but the sensitivity for lesions smaller than 1 cm was only 53%. Although with SCTAP examination of hepatic vasculature and liver parenchyma was continuous, we found no advantage in the localisation of lesions to the liver segments compared to CTAP, and the sensitivity of localisation did not correlate with the size of lesions.
In our study SCTAP turned out to be a reliable radiological method in the preoperative detection of focal liver lesions, with a high overall sensitivity. SCTAP showed improved sensitivity in the detection of small malignant lesions (< 1 cm) in comparison to CTAP.
为了确定动脉门静脉造影螺旋CT（SCTAP）在检测和定位肝脏局灶性病变中的价值，我们将SCTAP的检查结果与传统动脉门静脉造影CT（CTAP）的检查结果进行了比较。
我们评估了128例患有162个肝脏恶性病变患者的CT扫描结果。45例患者接受了SCTAP检查，83例患者接受了CTAP检查。将放射学研究结果与手术和病理结果进行了比较。
SCTAP的总体敏感性为93%，对于直径小于1cm的病变，敏感性为80%。CTAP的总体敏感性为88%，但对于小于1cm的病变，敏感性仅为53%。尽管通过SCTAP对肝血管和肝实质的检查是连续的，但与CTAP相比，我们发现在将病变定位到肝段方面没有优势，并且定位的敏感性与病变大小无关。
在我们的研究中，SCTAP被证明是一种在术前检测肝脏局灶性病变方面可靠的放射学方法，总体敏感性较高。与CTAP相比，SCTAP在检测小的恶性病变（<1cm）方面显示出更高的敏感性。
