		DOI:
		Objective: To study the value of magnetization transfer imaging(MTI) in the differentiation of brain abscess from necrotic or cystic glioma and metastasis. Materials and Methods: The conventional MR imaging and MTI of SE sequence were performed before operation or treatment in 7 patients with brain abscess(3 cases histopathology verified and 4 cases clinical follow-up confirmed) and 9 patients with necrotic or cystic glioma(confirmed by histopathology) and 8 patients with necrotic or cystic metastasis (clinically confirmed). Mean MTR of cystic and solid parts in abscess, glioma and metastasis, contralateral normal white matters and cerebrospinal fluid were measured and calculated. Results: MTR of cystic and solid parts in all lesions, contralateral normal white matter and cerebrospinal fluid were 0.0770±0.03, 0.2239±0.03, 0.3089±0.020, -0.0032±0.03 respectively. The difference of MTR between cystic parts of all lesions and cerebrospinal fluid was significant(t=9.933, P<0.001). The difference of MTR between solid parts of all lesions and contralateral normal white matters was significant(t=-14.509, P<0.001). The difference of MTRs among abscess, necrotic or cystic area of glioma and metastasis was significant(χ2=17.486, P<0.001), especially, there was significant difference between abscess and necrotic or cystic area of glioma or metastasis(abscess&glioma: P<0.001 and abscess&metastasis: P<0.001), however, there was no difference between necrotic or cystic area of glioma and metastasis(P>0.20). The difference of MTR among solid parts of abscess, glioma and metastasis was not significant. Conclusion: MT imaging and MTR could play an important role in differentiating brain abscess from necrotic or cystic glioma and metastasis on the middle feild, and MR system was an important supplement for routine MRI.

	547	MR diffusion weighted imaging with background suppressionin the diagnosis and differential diagnosis of focal hepatic lesions
		HU Yi;GUO Qi-yong
		DOI:
		Objective: To study the value of MR diffusion weighted imaging with background suppression(DWIBS) in the diagnosis and differential diagnosis of focal hepatic lesions. Materials and Methods: Eighty-nine focal hepatic lesions of 60 patients were brought into study, including 28 hepatic metastases, 32 hepatic cellular carcinomas(HCC), 8 hemangiomas, 17 hepatic cysts, 2 hepatic abscesses, 1 focal nodular hyperplasia and 1 biliary adenocarcinoma. Values of apparent diffusion coefficients(ADCs) were calculated and compared. To find remote lesions, large-scale DWIBS with 3D-MIP reconstruction was performed on several patients. Results: ADC values of benign lesions were higher than those of malignant ones(P<0.05) and 1.6×10^-3mm²/s can be set as the criteria for benign lesions versus malignancy with both sensitivity and specificity higher than 90%. ADC decreased in HCC and metastasis, while that of hemangioma and hepatic cyst increased in turn. The ADClesion/ADCliver ratio can be used to differentiate HCC, metastasis and hemangioma(P<0.05). Remote lesions were found on some patients by large-scale scanning, which can confirm the diagnoses of metastasis. Conclusion: MR DWIBS may be a useful tool for diagnosis and differential diagnosis of focal hepatic lesions.

		DOI:
		Objective: To evaluate the diagnostic and clinical application value of 16-slice three dimensional CT angiography(3D-MSCTA) with volume reconstruction(VR) technique in intracranial aneurysms. Methods: 3D-MSCTA of 36 patients clinically suspected intracranial aneurysms were analysed restrospectively. Source images were got by GE Light Speed pro Scanner. The images of 36 patients were processed with VR and maximum intensity projection(MIP). Results: Thirty-nine intracranial aneurysms in 36 patients (3 patients had 2 aneurysms) were found by 3D-MSCTA, the location of aneurysms was in the anterior cerebral artery in 3, in the anterior communicating artery in 11, in the internal carotid artery in 5, in the middle cerebral artery in 9, in the posterior communicating artery in 9, in the cerebral basal arterial circle in 1, and in the vertebral artery in 1. DSA displayed 19 intracranial aneurysms in 18 patients(1 patient had 2 aneurysms), 2 aneurysms were verified by surgery in 2 patients. There was no significant difference between VR and DSA in size ranging of intracranial ameurysms(t=0.59, P>0.05). The position, size and width of the neck of intracranial aneurysms in 18 patients displayed by 3D-MSCTA were accordant with the results of DSA. Conclusion: 3D-MSCTA VR can display intracranial aneurysms clearly, and provide valuable information for surgery or interventional therapy. 3D-MSCTA VR is a very quick, economical and effective method in the diagnosis of intracranial aneurysms.

	554	The relationship between 99mTc-MIBI breast cancer imaging andthe expression of multidrug resistance-associated protein and Ki-67
		LIN Kai-wen;LIU Bao-ping;CHENG Bing
		DOI:
		Objective: To investigate the relationship between 99mTc-MIBI breast imaging results and expression of the drug resistance proteins[multidrug resistance-associated protein(MRP), Ki-67] in human breast cancer tissues. Methods: Thirty-six patients with untreated breast cancer were studied prospectively a week before their surgical operations. They were all injected intravenously with 740MBq 99mTc-MIBI in the arm contralateral to the lesion. Anterior planar images were acquired at 10 and 180 minutes after injection and radioactive washout indices(WI) were calculated. MRP, Ki-67 expression was investigated by immunohistochemical studies on multiple nonconsecutive sections of surgical samples. The differences of the tumor radioactive WI between MRP positive and negative groups, Ki-67 positive and negative groups were compared with. Results: The WI were significantly higher in 13 patients with positive MRP expression when compared with 23 patients with negative MRP expression(16.72±10.17 and 1.76±2.38, P<0.005). However, the differences of WI between the patients with positive and negative Ki-67 expressions were not significant?穴12.47±11.26 and 13.06±12.63, P>0.50). Conclusions: A strong positive correlation was found between the WI of 99mTc-MIBI from the lesions and expression of MRP in untreated breast cancer patients(r=0.783, P<0.001). The WI of 99mTc-MIBI breast imaging may be a useful method for evaluating MRP expression in breast cancer. No significant relationship between 99mTc-MIBI breast imaging results and Ki-67 was found.

		SONG Yan;QIAN Yun-qiu;ZHANG Hai-bin;LI Hong-ling;LIU Li-wen;ZHENG Min-juan;CUI Kai
		DOI:
		Objective: To investigate longitudinal strain rate during isovolumic relaxation period of left ventricle(LV) in normal subjects by strain rate imaging(SRI). Methods: The LV wall was divided into six walls and each wall into three segments. SR-Time waves were observed. Both positive and negative peak strain rate in isovolumic relaxation period were measured(SRIVR+, SRIVR-). They were corrected by peak strain rate of systolic and early relaxation period respectively(SRIVR+/SRE, SRIVR-/SRS). Time data were also measured. All the parameters were compared among different walls and segments. Results: There were four modes of movement during isovolumic relaxation period. Most segments relaxed. There’s no significant difference in SRIVR+ among walls, while from basal to apical level, SRIVR+ decreased. SRIVR+ correlated well with age. Other segments had contracting waves. SRIVR- was larger in interventricular septal walls. From basal to apical level, SRIVR- also decreased. SRIVR- in apical level correlated with age significantly. Conclusions: Relaxation and contraction of LV wall in normal subjects during isovolumic relaxation period can be quantitatively evaluated by SRI, which may be the base of further study on dysfunctional myocardium.

		DOI:
		Objective: To evaluate the relationship between C-erbB-2, MVD expressions in ovarian tumors and the blood flow of CPA. Methods: Fifty cases of ovarian tumors were examined preoperatively by CPA whereas C-erbB-2 and MVD were stained with immunohistochemistry after operation. Results: The positive expression rate of C-erbB-2 in malignant ovarian tumors was 83.33% which was higher than that in the benign group(30%, P<0.05), the MVD value of malignant ovarian tumors showed positive correlation to the degree of CPA(r=0.823, P<0.05), the MVD value(53.37±7.91) in the positive C-erbB-2 groups including benign and malignant ovarian tumors was higher than that in negative C-erbB-2 group(38.93±3.19, P<0.05). MVD in the malignant ovarian tumors(48.84±6.19) was higher than that in the benign group(20.90±2.71, P<0.05). Their MVD demonstrated a positive correlation to the degree of CPA. The RI value of malignant group(0.36±0.06) was significantly lower than that of the benign group(0.68±0.07, P<0.05). RI values and MVD showed negative correlation(r=-0.806, P<0.05). Conclusion: The expressions of C-erbB-2 and MVD for ovarian tumors support CPA pathologically and the latter provides in turn the sensitive blood flow information for diagnosis of benign and malignant ovarian tumors in clinic.

		JIN Biao;ZHU Ming-jie;XUE Jian-ping;ZHU Li-hua;LI Yu-hua;ZHU Ming
		DOI:
		Objective: Rhabdomyosarcoma(RMS) lack characteristic imaging features. The purpose of this paper was to evaluate imaging diagnosis and relationship with pathology. Methods: Ultrasound, CT, MRI and pathologic data of 34 patients were analyzed retrospectively. Results: The original site of the tumor of these 34 patients(male 26, female 8) were: genitourinary tract 12, peritoneum and retroperitoneum 8, head and neck 6, extremities 6 and trunk 2. On B-mode ultrasound, RMS tend to be a solid homogeneous or heterogeneous mass. On CT, RMS appear as an isodense, hypodense or slightly hyperdense mass with or without focal infiltrations. On MRI, typical RMS are isointense or nearly isointense to muscle on T1WI, are hyperintense on T2WI. RMS demonstrate enhancement after injection of contrast medium. The pathologic type of these 34 patients were: embryonal type(n=30), alveolar type(n=2), pleomorphic type(n=2). Conclusions: The diagnostic imaging of RMS are consistent with its pathologic features. The accurate diagnosis highly correlates with the age of the patients and the location of the tumor.
