		DOI:
		Objective: To verify the accuracy of brain anatomic and functional area extraction method for 99mTc-ECD SPECT imaging, and preliminary assess the 99mTc-ECD distribution among the 63 functional areas in the brain. Methods: By image registration and deformation, the 99mTc-ECD SPECT images are mapped into Talairach space, and the individual brain functional area’s coordinates are classified, so that each area average gray scale can be calculated, also the gray scale difference between half brain of left and right is compared. Results: The 99mTc-ECD brain images are successfully registered into the standard Talairach coordinates space, the anatomic and functional areas are extracted, which can be rendered perspectively in the SPECT image template, and the position relation is close to the area drawn by the eye. The uptake of the 99mTc-ECD is asymmetric between the left and the right for most of brain area, and even in the same part of brain, the uptake for this trace is quite different among the fields of brain. The precuneus, lingual gyrus and inferior parietal lobule are ranked the top three according to the 99mTc-ECD distribution, meanwhile the orbital gyrus, corpus callosum and the caudate tail are the least three area for the trace uptake. Conclusion: The brain automatically extract can analyze the brain different area quickly, correctly and repetitively. This method can be used not only to study the individual object, but also fit to statistical analysis for a sample.

		ZHANG Sheng-jian;YIN Hua-bin; ZHUANG Yu-zhong;JIANG Pei
		DOI:
		Objective: To assess the value of MSCTA and US for finding carotid artery atherosclerosis plaque，detecting plaque components and estimating the grade of carotid stenosis in patients with cerebral infarction and to discuss the correlation of the two method results. Methods: In 41 patients with cerebral infarction MSCTA and US were performed, 4/41 also had DSA examination. Location and characteristic of plaques, the grade of vessel stenosis were discerned. Coherence statistical method were used to find agreement of the two methods. Results: 68.85%(28/41), 82.93%(34/41) patients were found extracranial carotid, carotid atherosclerotic plaque; MSCTA and US separately detected 76 and 69 plaques; the agreement in detected 60 plaques components which two methods all found was 75%(45/60), the value of Kappa was 0.5915; the overall agreement of carotid stenosis grade obtained by two methods was 78.26%. The value of Kappa was 0.6882. Compared with DSA, 3 carotid occlusions were diagnosed correctly by CTA, but only 1 diagnosed correctly by US, other 2 underestimated as moderate and severe grade stenosis respectively. Conclusions: A close relation existed between carotid atherosclerotic plaque and brain infarction. There were fine agreement of MSCTA and US in detecting plaques components and estimating stenotic grade. MSCTA maybe found more plaques than US and was a more reliable method in diagnosis of carotid occlusion than US.

		LAN Ri-hui;ZENG Qing-si;SUN Chong-peng;CHEN Ling;ZHENG Ze-guang;ZHENG Jin-ping;WU Hua
		DOI:
		Objective: To study the correlation between high resolution CT(HRCT) findings, recovery of respiratory function tests and clinical data of SARS patients in the convalescent phase. Methods: Forty-nine patients with confirmed SARS underwent initial thin-section CT and forty patients underwent respiratory function tests. Sixteen and thirteen patients underwent follow-up examination. The clinical data were retrospectively analysed. CT visual score were quantitatively analyzed for lung abnormalities. Results: Ground-glass opacities and interstitial opacities were found in 25(51%), 22(45%) of the 49 patients on initial HRCT and in 6(38%), 7(44%) of the 16 patients on the follow-up HRCT examinations. The initial and follow-up CT visual score indicated a significant reduction in the extent of ground-glass opacity(P<0.001) but not in that of interstitial opacity. Scan from patients with adult respiratory distress syndrome(ARDS) had a significantly higher score for ground-glass opacity than did those from patients without ARDS(P<0.05). Dlco％ were correlated with sex and ground-glass opacity score. Conclusion: HRCT findings were correlated with clinical data, laboratory tests and respiratory function tests, residual abnormalities and respiratory function tend to be better over the time, but interstitial opacity persists.

	619	Biphasic scanning and postprocessing reconstruction images with MDCT: clinical significance in evaluating renal vein abnormalities
		WANG Qiu-shi;LIANG Chang-hong;LIU Hui;YU Yuan-xin;XIE Shu-fei;LIU Yu-bao
		DOI:
		Objective: To investigate the clinical significance of biphasic scanning and postprocessing reconstruction images with MDCT in evaluating renal vein abnormalities. Materials and Methods: Eighteen cases with renal vein abnormalities on MDCT were analyzed retrospectively, which included renal vein variations in 3 cases, venous thrombi in 9 cases, left renal vein entrapment syndromes in 3 cases, splenorenal shunt, arteriovenous fistula and vein aneurysm in each case respectively. The ability to display renal vein abnormalities on biphasic scanning and all kinds of postprocessing reconstruction images were compared. Results: ①Renal vein abnormalities and concomitant lesions were clearly displayed on biphasic scanning images of MDCT. All renal vein abnormalities could be found preliminarily on arterial phase images. Renal vein tributaries, collateral vessels, tumor thrombus and associated abnormalities of venous system could be more predominant on venous phase images than those on arterial phase images. ②The information of exterior and interior to the lumen of vein could be displayed clearly on MPR, but whole vessel anatomy could not be manifested. Circuitous renal vein could be spread on CPR, but adjacent structures were also deformed. Renal vein anatomy and lesion were showed best on MIP, and especially thin-slab MIP had the advantage to decrease image overlap. VR had strong ability to display vessel configurations and was better than MIP at displaying overlapping vessels and arteriovenous malformations, but it could not show venous thrombosis. Conclusion: Biphasic scanning and appropriate postprocessing reconstruction methods on MDCT could demonstrate the renal vein anatomy and lesion satisfactorily and might be an accurate and safe method to evaluate renal vein abnormalities and concomitant lesions.

		LIU Yan;ZHU Ming;LI Yu-hua;XU Bin
		DOI:
		Objective: To find the best imaging examinations for conjoined twins by reviewing the previous cases. Methods: The imaging exams from the six previous cases were analyzed retrospectively, and the results were compared in relation to pathology and operative result. Results: There were five pairs of thoraco-omphalopagus conjoined twins among the six cases, and the other pair was ischiopagus. The five thoraco-omphalopagus cases all had conjoined livers and portions of the chest bones fused. All the patients of the six cases had different kinds of congenital heart disease. The ischiopagus conjoined twins had the common rectum. The operation results match with the imaging diagnosis. Conclusion: The inside abnormality of conjoined twins can be better understood by using suitable imaging exams, which has important significance for the evaluation of the operation and the overall prognosis.

		DOI:
		Objective: To explore medical imaging in the diagnosis of conjoined twins, in order to get ready for operative separation. Materials and Methods: Two cases of conjoined twins imaging data were collected including GI and CT, MRI and radionuclide imaging of our hospital, their special symptoms were analyzed. Results: The liver of the first conjoined twins joined together, their pericardia conglutinated mildly, there was no crossed big blood vessel in the liver, and the liver’s metabolism and function were normal. Both of them have independent bile duct system, digestive system and urinary system. The heart and liver of the second conjoined twins joined together, and there was no other conjoint organ. Conclusion: Conjoined twins imaging data almost fully reflect the extent of the united viscera and its crossed blood vessel, metabolism and function, which can guide surgeons to establish operation planning. Combined imaging modalities plays the important role to insure successful operative separation.

		DING Xiao-yi;DU Lian-jun;LU Yong;YAN Ling;JIANG Hao;CHEN Ke-min
		DOI:
		Objective: To describe the difference of the clinical symptoms and radiologic features between Ewing sarcoma(ES) and peripheral primitive neuroectodermal tumors(pPNETs) of bone, and to benefit from the differential diagnosis and treatment. Materials and Methods: We retrospectively reviewed 18 cases of ES and 10 cases of pPNETs all were confirmed pathologically. Radiologic and clinical studies were reviewed by two musculoskeletal radiologists. In ES, radiographs(n=18), CT(n=12), MRI(n=9) were performed. In pPNETs, radiographs(n=10), CT(n=7), MRI(n=10) were performed too. The evaluation included clinical presentation,lesion location and size,bone erosion/destruction,periosteal reaction, soft tissue involvement and intrinsic characteristic findings on CT and MRI. Results: Patients’ average age was 18.5 years (range 10～28) and 24.4 years(range 8～86) in ES and pPNETs respectively. For the ES, the lesion locations included femur(n=6), humerus(n=4), clavicle(n=2), tibia(n=1), fibula(n=1), ulna(n=1), ilium(n=1), sacrum(n=1) and acetabulum(n=1); Radiographs(n=18) showed lytic lesion(7/18), with irregular sclerosis and matrix mineralization(11/18), soft tissue mass(10/18), periosteal reaction(10/18), eccentric(6/18), scalloping of cortex(3/18); CT(n=12) showed lytic lesion(4/12), lesion with irregular sclerosis and matrix mineralization(8/12), soft tissue mass(10/12), periosteal reaction(6/12); On MRI(n=9), T1WI showed isointensity(8/9) and slightly hyperintensity(1/9), T2WI and STIR images showed heterogeneous hyperintensity(9/9), soft tissue mass(8/9), the size ranged from 2cm×3cm to 3cm×10cm. For the pPNETs, the lesion locations included ilium(n=3), humerus(n=2), corpus vertebrae(n=1), arcus vertebrae(n=1), scapula(n=1), sacrum(n=1), sphenoid(n=1); Radiographs(n=10) showed lytic lesion(8/10), with irregular sclerosis and dilation(1/10), and normal(1/10), soft tissue mass(7/10), periosteal reaction(0/10). CT(n=7) showed lytic lesion(6/7), lytic lesion with irregular sclerosis and dilation (1/7), soft mass(7/7), speculate calcification(2/7), periosteal reaction(0/10); On MRI(n=10), T1WI showed isointensity(9/10) and slightly hyperintensity(1/10), T2WI and STIR images showed heterogeneous hyperintensity (8/10), uniform hyperintensity(2/10), soft tissue mass(10/10), the size ranged from 2.5cm×4cm to 7.5cm×13.5cm. Conclusion: The clinical and radiologic features of ES and pPNETs were different, compared with pPNETs, the patients with ES were younger, the commoner locations were long tubular bones, radiography and CT showed periosteal reaction and matrix mineralization, MRI showed the similar intensity but with smaller soft tissue mass, these features were helpful in differential diagnosis if combining with pathology.

		DOI:
		Objective: To study the safety and clinical therapeutic effect of Oasis catheter thrombolysis and Amplatz Thrombectomy Device(ATD) in the treatment of thrombosis in arteries of lower extremity combining recombinant human tissue-type plasminogen activator(rt-PA) or urokinase(UK). Methods: Practise emergence operations were done with Oasis(12 cases) tube thrombolysis or ATD(6 cases) tube macerate thrombolysis for 18 patients suffering thrombosis of arteries of lower extremity, giving rt-PA thrombolysis (2 cases) and UK thrombolysis(7 cases) for distal end small vessels remaining thrombus. Percutaneous transLuminal angioplasty(PTA) or stenting treatments were done for five segments of ilio-femur arteries in four patients. Among 18 patients, there are 3 iliac arteries, 13 femoral arteries, 1 popliteal artery, and 1 widespread thrombosis including femoral artery, popliteal artery, anterior and posterior tibial artery and ped-artery. Results: Technologic achievement ratio is 100% for the 18 cases. 14 cases completely recanalization immediately after treatment; 4 cases completely recanalization afer continue thrombolysis for 3 to 5days by detaining catheter. In 4 cases with 5 stenosis arteries segments, recanalization rate is 95% after taking transLuminal angioplasty or stents, clinical amelioration rate is 100%. The arteries of all cases remain open after 1～45 months by DSA, B supersound and clinical following up. Without complication of vessels perforation and amputated extremity, only one case of digestive tract bleeding. Conclusion: Mechanical thrombolysis with Oasis or ATD catheters combining rt-PA or UK drugs can rapidly dissolved the thrombus of artery of lower extremity, with high safety and great clinical therapeutic effect. Using PTA and stents assistant treatment can effectively relieve stenosis of arteries, prevent reforming of thrombus and avoid amputation of lower extremity.
