DOI:
Objective: To assess the value of real-time three-dimensional echocardiography(RT-3DE) in the evaluation of left ventricular function in patients with coronary artery disease(CAD) after percutaneous coronary intervention(PCI). Methods: RT-3DE was performed in 30 patients who accepted PCI treatment successfully and 20 normal subjects who had no coronary artery stenosis. RT-3DE was performed and three-dimensional image data were analyzed. Series of left ventricular parameters were measured in 3~5 days pre-, 3 days post- and 1 month post-operation. Left ventricular end-diastolic volume(EDV), end-systolic volume(ESV), ejection fraction(EF), the peak ejection rate(PER), peak filling rate(PFR), the time to the point with minimal systolic volume(Tmsv) in 16 segments standard deviation and the maximal difference of time(Tmsv16-SD, Tmsv16-Dif). These parameters were respectively compared. Results: Compared with normal subjects, EDV, ESV, Tmsv16-SD, Tmsv16-Dif were significantly increased(P<0.01). EF, PER and PFR in patients group were significantly decreased(P<0.01). Compared with pre-operation, EDV, Tmsv16-SD, Tmsv16-Dif were significantly decreased respectively. Meanwhile whole EF, PER and PFR were significantly increased after PCI. Conclusion: Left ventricular remodeling could be found in patients with CAD. PCI might reverse left ventricular remodeling somewhat. RT-3DE could be a new corrected valuable method of evaluating left ventricular remodeling and reverse remodeling in patients with CAD pre- and post-PCI.

DOI:
Objective: To explore the feasibility of interventional treatment for vessel and bile duct reconstruction correlated complications after liver transplantation. Methods: Interventional procedures were carried out in 16 cases of complications after liver transplantation including 4 cases of hepatic artery stenosis, 2 cases of hepatic artery thrombosis, one case of portal vein stenosis combined thrombosis and blood shunt, 9 cases of bile duct stenosis. PTA or stent placement were performed in patients with stenostic complications, thrombolysis for patients with thrombosis and coil embolization for blood shunt. Results: The technical success rate was 100% in all of the 16 patients. In the patients with hepatic artery stenosis, one case received PTA and other 3 cases received stent placement. The thrombosis disappeared and blood flow restored after treatment in patients with hepatic artery thrombosis. Portal vein blood restored and blood perfusion increased in the patient with portal vein complication. The bile ducts were rebuilt after the treatment of PTA in 2 patients and stent placement in 7 patients. Five patients died in the follow up of half to 17 months but were not relevant to the complications and interventional procedures. Conclusion: Interventional radiological technique is believed to be effective in the treatment of vessel and bile duct reconstruction correlated complications after liver transplantation.

WU Jian-ming;MA Zhou-peng;ZHANG Shun-zhuang;ZHOU Jian-jun
DOI:
Objective: To analyse the multi-slice spiral CT(MSCT) appearances of hepatic lymphoma, and improve its diagnostic accuracy. Methods: Eight cases of MSCT findings with hepatic lymphoma were reviewed which were proved by pathology or clinical follow up. Results: There were 6 cases of secondary lymphoma, and 2 cases of primary lymphoma. In the 8 cases 3 cases with single focus, 5 cases with multi-foci, in 6 cases the lesion located near the branch of portal vein or converge area, in 2 cases the lesion located in the border of liver. The foci showed low density on plain scan, CT value were 18.8~32.1HU; in 3 cases the lesion appeared as round or oval, 4 cases were multi-irregular tumors, and 1 case appeared as diffused with multi-speckled nodules in left lobe of liver. 4 cases tumors had clear edge, the other 4 cases with dim edge. 2 cases with local dilation of bile duct. In contrast enhancement, 6 cases intensified slightly in arterial phase and the intensity was lower than normal tissue, 2 cases intensified obviously in arterial phase, the density was higher than normal tissue, 8 cases with continued enhancement in portal vein-phase, but were fainter than normal tissue, in delayed phase, the enhancement of tumor decreased, blood vessels were seen within the lesion in 6 cases as “blood vessel floating-sign”, the vessel was compressed. Six cases had enlarged retroperitoneal lymph-nodes with different sizes, slightly to moderate homogeneous enhancement, and without obvious necrosis. Calcification and necrosis were not be seen in all tumors. Conclusion: Hepatic lymphoma can be single or multiple tumor, located near the branch of portal vein or its supplied area, without obvious necrosis, CT showed homogeneous density on plain scan, and with slightly to moderate homogeneous enhancement. Some tumors showed “blood vessel floating-sign”. MSCT can show the position, number, shape of tumor and the blood supply clearly and the change of adjacent tissue and organ, is useful for the diagnosis of hepatic lymphoma.

DOI:
Objective: To investigate the potential of diffusion-weighted MR imaging(DWI) in differentiating primary malignant liver tumor enhanced in delayed phase on contrast-enhanced MRI and cavernous hemangioma. Materials and Methods: Diffusion weighted MR scans were performed using an 1.5T MR scanner at a b value of 500s/mm2 in 32 cases of focal hepatic lesions enhanced in delayed phase on contrast-enhanced MRI, including 11 cavernous hemangiomas and 21 primary malignant tumors(9 hepatocellular carcinomas, 12 cholangiocarcinomas). Quantitative analysis was performed using the regions of interest(ROI) settled on these tumors. The mean ADC values of cavernous hemangioma, hepatocellular carcinoma and cholangiocarcinoma were calculated and analyzed by student t tests respectively. P value of less than 0.05 was considered to indicate statistical significance. Results: The mean ADC value of hepatocellular carcinoma[(1.28±0.46)×10-3] and cholangiocarcinoma[(1.61±0.38)×10-3] were significantly lower than that of cavernous hemangioma[(2.85±0.89)×10-3](t=4.780, P=0.000; t=3.7025, P=0.001 respectively). However, there were no significant differences of mean ADC values between hepatocellular carcinoma and cholangiocarcinoma(t=1.8008, P=0.088). Conclusion: DWI might be helpful to differentiate primary malignant liver tumor enhanced in delayed phase on contrast-enhanced MRI from cavernous hemangioma.

DOI:
Objective: To evaluate the value of combined different postprocessing techniques using 256 slice spiral CT for the visualization of right inferior phrenic artery(RIPA). Methods: Double-phase contrast enhanced scan was performed in 98 patients including 12 cases of HCC to observe RIPA using three different postprocessing combination techniques. The cases were divided into three groups: Group A(MPR+MIP), Group B(MPR+VR), and Group C(MPR+CPR). Results: The ability of showing the origin and distribution of RIPA in Group A was higher than those in Group B and Group C. Conclusion: MPR+MIP postprocessing techniques can display distribution of RIPA clearly, which can be used as a first choice and accurate noninvasive examination method to evaluate the extrahepatic blood supply in preoperative TACE of HCC.

DOI:
Objective: To explore the value of extra-pancreatic lesions on 18F-FDG PET/CT image in the diagnosis of pancreatic cancer. Methods: Seventy-three patients, 52 male and 21 female, suspected of having pancreatic cancer underwent 18F-FDG PET/CT scan. Surgical operation(18 cases), open abdominal surgery for exploration(4 cases), fine-needle aspiration(25 cases), imaging and clinical follow-up(28 cases), confirmed malignancy in 47 cases and benignity in 26 cases. Preliminary diagnoses were based on the SUV value and CT characteristics of the primary lesions in pancreas, and the confidential level of diagnoses as malignancy as graded as affirmative and probable. Extra-pancreatic lesions detected on 18F-FDG PET/CT image were classified as metastatic and non-metastatic, and the diagnoses were modified by extra-pancreatic lesions. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value before and after modification were calculated. Results: Extra-pancreatic lesions were identified on PET/CT image in 29 patients, among which 26 were metastatic and 3 were non-metastatic lesions. Those lesions modified the diagnoses in 21 cases. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value before and after modification were 83.0%, 69.2%, 78.0%, 83.0%, 69.2% and 93.6%, 76.9%, 87.7%, 88.0%, 87.0% respectively. For the 6 false positive cases on PET/CT, 3 of them were proved to be solid pseudopapillary tumors(SPT). Conclusion: Extra-pancreatic lesions, especially metastatic lesions identified on 18F-FDG PET/CT image improved the diagnostic accuracy of pancreatic cancer. SPT was identified as the most important reason of false positive diagnoses after modification by extra-pancreatic lesions.

328 Role of 18F-FDG PET and PET/CT in detection of unknown primary tumor:a systematic review and Meta-analysis of the literature
YANG Zhong-yi;XU Jun-yan;HU Si-long
DOI:
Objective: To evaluate the diagnostic accuracy of 18F-FDG PET and PET/CT in the detection of primary tumors. Methods: Publications were collected from the English and Chinese literatures on PET or PET/CT imaging in detecting primary tumors of patients presenting with carcinoma of unknown primary(CUP) unidentified by conventional workup(before March 31, 2010). Systematic methods were used to identify, select, and evaluate the methodological quality of the studies. The pooled sensitivity, specificity, positive likelihood ratio(LR+), negative likelihood ratio(LR-), diagnostic odds ratio(DOR) and summary receiver operating characteristic(SROC) curves were obtained through Meta analysis. Results: 24 studies were analyzed(14 studies of PET and 10 studies of PET/CT). The detection capacity of the primary tumor of PET and PET/CT was 40.86%(344/842); 37.60%(144/383) for PET and 43.57%(200/459) for PET/CT, respectively. The primary tumors detected by PET and PET/CT mostly located in lung, tonsil and gastrointestinal tract. The pooled sensitivity, specificity, LR+, LR- and DOR of PET were 88%(82%~92%), 80%(74%～85%), 3.55(2.14～5.88), 0.24(0.16～0.36) and 24.94(11.36～54.78), respectively. As for PET/CT, there were 90%(86%~94%), 84%(79%～89%), 5.19(3.48～7.74), 0.07(0.02～0.25) and 80.02(20.42～313.48), respectively. The areas under the curve in SROC were 0.9074 and 0.8758, respectively. Q* value were 0.8393 and 0.8063, respectively. False positive was mostly seen in lung, tonsil and oropharynx. However, false negative was mostly seen in breast, tonsil, base of tongue and bone. Conclusion: 18F-FDG PET and PET/CT could be valuable imaging modalities in patients with CUP beyond what was provided from a conventional workup.
