Objective: To explore the reliability of 3D TOF MRA on 3.0T MR system for preoperative assessment of intracranial vascular stenosis. Methods: Thirty patients with intracranial arterial stenosis in the 2nd Hospital Affiliated to Harbin Medical University, who received both 3D TOF MRA on a 3.0T MR system and rotational digital subtraction angiography examinations. 450 vascular segments of the 30 patients were analysed. Without stenosis, mild stenosis(10%~＜50%), stenosis of 50%, 70%, 100% as decision point to calculate sensitivity, specificity, positive predictive value(PPV) and negative predictive value(NPV) of MRA. Results: Compared to DSA, 115 lesions were detected, the sensitivity and specificity were 87.0% and 99.7% for MRA in detecting stenosis. Take 50% as the critical point. The sensitivity and specificity was 86.7% and 99.5% respectively, the PPV was 92.9% and the NPV was 99.1%. Take 70% as the critical point the sensitivity and specificity was 95.5%, 99.5% respectively, PPV 91.3% and NPV 99.5%. MRA diagnosed 7 in the eight occlusions. One false positive and one false negative(that was stenosis of the basilar artery and intracranial segment of the vertebral artery). Twenty-eight(24.6%) segments were overestimated, 7 segments were underestimated. Conclusion: To determine 50% and 70% intracranial arterial stenosis, 3.0T 3D TOF MRA has high sensitivity and specificity compared to rotational DSA, and can be used as an effective means in pre-stenting surgery.

DOI:
Objective: To investigate the possibility of using MDM2 molecular imaging on evaluating chemotherapeutic response in breast cancer xenograftm, the molecular probe was synthesized using MDM2 antisense oligonucleotide(AS). Methods: The MCF-7 cell of different MDM2 expression was transfected with paclitaxel. The inhibition efficiency of MCF-7 to paclitaxel was observed by MTT assay. MDM2 AS was radiolabeled with 99Tcm. The level of MDM2 expression was evaluated with molecular imaging in the breast cancer xenograft of different MDM2 expression. Two group xenografts of different MDM2 expression were treated with paclitaxel. The tumor volume was determined at different times and growth curve was drawn. Results: The MCF-7 cell of different MDM2 expression have various response to the paclitaxel. The tumor of higher MDM2 expression have lower response to paclitaxel. MDM2 molecular imaging can evaluate the MDM2 expression in breast cancer xenograft. The breast cancer xenograft of various MDM2 expression have different inhibition efficiency to paclitaxel. Conclusion: MDM2 molecular imaging can exactly evaluate the MDM2 expression prior to the chemotherapy and anticipate the sensitivity of the breast cancer xenograft to chemotherapy.

DOI:
Objective: To explore the impact of reperfusion injury on myocardial systolic function by speckle tracking imaging. Methods: Left anterior descending(LAD) coronary of 20 healthy adult hybrid dogs were ligated for 180 minutes following by reperfusion for 120 minutes. Circumferential strain of basal, papillary muscle and apical level were compared by speckle tracking imaging before LAD occlusion, LAD occlusion immediately, LAD occlusion for 180 minutes, reperfusion immediately, reperfusion for 60 and 120 minutes respectively. Results: Circumferential strain of basal level decreased after reperfusion and then increased above the basic status. Circumferential strain of papillary muscle level increased after reperfusion, but it was still lower than that of the basic status without significant difference. Circumferential strain of apical level increased and it was lower than that of the basic status with significant difference. Conclusion: Speckle tracking imaging can assess the influcence of reperfusion injury on myocardial contractility objectivly and accurately, which will provide an effective index for relieving the coronary obstruction early and choose proper treatment.

FAN Yi-sha;HOU Yang;ZHAO Peng-fei;LIU Qin;GUO Qi-yong
DOI:
Objective: To evaluate image quality(IQ) and effective radiation dose on 256-slice coronary CTA at 50% reduced radiation dose using iterative reconstruction(IR)(iDose4) and to assess the accuracy of this protocol in the diagnosis of coronary artery disease(CAD) in patients with atypical chest pain based on selective invasive coronary angiography as gold standard. Methods: Retrospective analysis of 132 consecutive patients(83 males, mean age 54 years, mean BMI 27) with atypical chest pain underwent low-dose 256-slice CT angiography with prospective gating(Brilliance iCT, Philips Healthcare). The tube output was reduced by 50% compared to our routine institutional protocol. Scanning conditions were as follows: 120 kVp, 105 mAs, using prospective ECG-triggering at 75% of R-R interval. The HR was stabilized and controlled to ≤70 beats/min. Images were reconstructed using IR, using iterative levels 4(IR), and standard convolution kernel(XCB). Two radiologists evaluated IQ(contrast, sharpness, subjective noise and image acceptability) using a 4-point scale in a blinded manner. Subjective score consistency, the mean of subjective score and the acceptability display of coronary segments were calculate. Of the 132 patients, 55 also underwent coronary angiography, with percent diameter stenosis ≥50% as positive, to calculate the sensitivity, specificity, accuracy, positive and negative predicative values of coronary CTA with IR. Results: Subjective score consistency was achieved(Kappa value, 0.66~0.84). The scores of contrast, sharpness, subjective noise and image acceptability were 3.97±0.17, 3.86±0.35, 3.89±0.32, 3.83±0.38, respectively. The percent of diagnostic segments in 132 patients was 98.8%(1 865/1 887). The CTDI, DLP, and ED were (8.19±0.18) mGy, (100.06±7.67) mGy·cm, and (1.40±0.11) mSv, respectively. In 55 patients underwent coronary angiography, low-dose scanning with IR exhibited high accuracy. The sensitivity, specificity, and accuracy were 93.75%, 97.03% and 97.04%, respectively(segment-based); and 96%, 93.3%, and 94.5%(patient-based). Conclusion: The iDose4 iterative reconstruction technique can maintain image quality in coronary CTA scanning at 50% radiation dose reduction, and can diagnose CAD with high accuracy.

174 Assessment of rat liver fibrosis with ΔR2* value in oxygen-challenge BOLD MR imaging: a preliminary study
ZHANG Lan;SHI Yu;BIAN Sheng-xin;GUO Qi-yong
DOI:
Objective: To explore the relationship between ΔR2* value in oxygen-challenge blood oxygen level-dependent(BOLD) MRI and the severity of liver fibrosis in a rat model, and assess the potential value of diagnosis of the disease using ΔR2* value. Methods: Liver fibrosis was induced in 90 rats by means of weekly intraperitoneal injection with a mixture of carbon tetrachloride and olive oil. Ten healthy rats were used as controls. BOLD-MRI study was performed on the rats under anesthesia at steady normoxia state by inhaling room air and hyperoxia state by inhaling oxygen. The changes in R2* values(ΔR2*) during the oxygen challenge were quantified on the post-processing workstation. According to the pathological results, the rats were divided into three groups: A: without fibrosis(S0), B: mild and moderate fibrosis(S1~S2), C: severe fibrosis and cirrhosis(S3~S4). The differences of ΔR2* among the groups were tested by ANOVA and the correlation between liver fibrosis degree and ΔR2* were analyzed by Spearman-test. Results: Thirty-two liver fibrosis model rats and 10 healthy rats were performed BOLD-MRI. Absolute values of R2* decreased after oxygen challenge in all rats. A statistically significance(P<0.05) in ΔR2* were observed between group A((24.05±4.65) Hz), group B ((17.18±4.50) Hz) and group C((8.09±5.17) Hz). ΔR2* decreased during liver fibrosis progression and was negatively correlated with liver fibrosis degree(r=-0.827, P<0.001). Conclusion: ΔR2* in oxygen-challenge BOLD-MRI can reflect hemodynamic and oxygenation alterations during the progression of liver fibrosis, and has the potential to serve as a noninvasive method for liver fibrosis diagnosis and severity evaluation.

DOI:
Objective: To investigate the diagnostic value of the acoustic radiation force impulse(ARFI) imaging technology and AST/PLT ratio index(APRI) for the assessment of the liver fibrosis in NAFLD patients. Methods: Sixty-seven patients with non-alcoholic fatty liver disease(NAFLD) were included, the subjects were underwent liver biopsy, liver function, blood count, as well as real-time ultrasonic elastography examination. The measurements of real-time ultrasonic elastography by ARFI technology using a ultrasonic instrument ACUSON S2000. The APRI was calculated according to the following formula, APRI=AST(ULN)/PLT(109 /L). ARFI and APRI were compared by correlation with liver fibrosis stage in NAFLD. Referring to the histologic fibrosis stage on liver biopsy, all the ARFI and the APRI value were assessed by using receiver operating characteristic(ROC) curve analysis. The corresponding cut-off values, sensitivity and specificity were also calculated and compared. Results: The mean values of ARFI and APRI were (1.177±0.281) m/s and (0.192±0.155) for the patients with S0, (1.249±0.308) m/s and (0.190±0.097) for those with S1, (1.436±0.521) m/s and (0.306±0.195) for those with S2, (1.538±0.496) m/s and (0.224±0.094) for those with S3, (1.857±0.729) m/s and (0.373±0.295) for those with S4, respectively. ARFI(r=0.416, P＜0.01) had a better correlation with liver fibrosis stage in NAFLD than APRl(r=0.254, P＜0.05). The areas under the ROC curves(AUC) for ARFI and APRI were 0.714 and 0.653 for S≥2, 0.765 and 0.577 for S≥3, 0.853 and 0.611 for S=4, respectively. Conclusions: As a non-invasive technology, ARFI is more accurate when applied to evaluate liver fibrosis in patients with NAFLD than APRI. ARFI technology has potential value for quantitative evaluation of the liver fibrosis for NAFLD.

DOI:
Objective: To explore the feasibility and clinical application value of hand push injection of gadolinium Tony dimeglumine to perform MR portal venography. Methods: Thirty patients suffering from liver disease were divided randomly into 3 groups, ten patients in each group. 20 mL of gadolinium Tony meglumine were quickly injected into the vein of the patients by hand push injection in the first group. 20 mL gadolinium spray acid meglumine were quickly injected into the vein of the patients also by hand push in the second group. 30 mL gadolinium spray acid meglumine were injected into the vein of the patients in the control group by high pressure syringe to perform portal venography. Then determine the signal value of the corresponding region of interest in the three groups and evaluated the image quality. Result: The image of the potal vein and its branches showed clearly in the first group, compared to the control group, the signal value had no significant difference(P>0.05). In contrast, the image of the portal vein and its branches in the second group was unclear and fuzzy, compared to the control group, there were significant differences between the signal values(P<0.05). Conclusion: Using gadolinium Tony meglumine as the contrast agent by hand push to perform MR portal venography has clinical application value. It can simplify the operation and can also achieve the same image quality as using gadolinium spray acid meglumine with a high pressure syringe and thus can reduce the cost of examination.

DOI:
Objective: To explore the clinical characteristics and MDCT findings of the subtle occult Lisfranc injury. Methods: During a period of 12 months in 2011, 706 patients had sprain injury of the foot underwent MDCT of the foot. Among them, occult Lisfranc injuries are not detected on conventional radiography. Imaging studies of MDCT were retrospectively re-evaluated for fracture location, and fracture types. Results: Of the 706 patients, 285 patients were normal on the radiological diagnosis. Among 285 patients, 113(39.6%) had one or more subtle fractures in the tarsals and the base of the metatarsals. Subtle occult Lisfranc injury were found in 82 patients. Pain and midfoot swelling were the main clinical characeristics. Common causes of indirect trauma include athletic injuries and falling from a high place. Conclusion: Subtle Lisfranc injuries are increasing and their correct diagnosis is important. Misdiagnosis is common and can lead to chronic disability. In patients with Lisfranc injuries, MDCT is recommended as the useful imaging technique.
