It is studied that a kind of communicatory model of medical image data transmission service of PACS according to the standard of DICOM 3.0. This model which lies between application layer of PACS and network interface in the bottom of TCP/IP, defines object, service and message of medical image data transmission service work based on TCP/IP.

Objective To study the role of multi-slice helical CT (MSCT) triple-phase images in the detection of small hepatocellular carcinoma (SHCC). Methods One hundred SHCC patients were detected by triple-phase spiral CT (THCT) with 5-mm-thick-section, among them, 74 cases were diagnosed by operations and 24 cases by transcathether arterial chemoembolization (TACE). Nonenhanced scans were obtained in all cases, along with hepatic arterial-phase (HAP), portal venous-phase (PVP), and delayed-phase (DP) images at 20-25...

Objective To study the role of multi-slice helical CT (MSCT) triple-phase images in the detection of small hepatocellular carcinoma (SHCC). Methods One hundred SHCC patients were detected by triple-phase spiral CT (THCT) with 5-mm-thick-section, among them, 74 cases were diagnosed by operations and 24 cases by transcathether arterial chemoembolization (TACE). Nonenhanced scans were obtained in all cases, along with hepatic arterial-phase (HAP), portal venous-phase (PVP), and delayed-phase (DP) images at 20-25 seconds, 45-50 seconds, and 2-3 minutes, respectively, after intravenous 1.5 ml/kg nonionic contrast material injection at a rate of 3 ml/s. The characterization of SHCC were studied by three radiologists with network imaging workstations of picture archiving and communication system (PACS) with software of RadworksTM 5.1. The correlation between the CT features and pathological changes in SHCC was studied. Results The sensitivity for all SHCC was as follows: HAP, 94%; PVP, 88%; and DP, 96% in THCT. The CT characterizations were iso- and hypodense in unenhanced CT scan, hyper- and isodense in HAP, hyper-, iso- and hypodense in PVP, iso- and hypodense in DP. There were significant differences in THCT (χ 2=211.953,P=0.001) and in histopathology typing (P=0.006 04). Eight-one case of SHCC expressed typical findings and 19 cases had non-typical findings on CT scan. Conclusion Most cases of SHCC have typical findings in CT enhanced scan. Detection of SHCC was well achieved in arterial-phase and delayed-phase scan, especially delayed-phase scan. Thin section THCT scan possesses an important significance in detection of SHCC. Complex triple-phase imaging characterizations can improve the diagnosis and differential diagnosis.
