Objective: To explore progressive stroke mechanism of early cerebral infarction by using dynamic susceptibility contrasted magnetic resonance imaging, to obtain and analyze the progressive and non-progressive patients’ hemodynamic parameters, provide valuable theory for improving clinical therapy and prognosis. Methods: Sixty patients with acute cerebral stroke during 24 h underwent dynamic susceptibility contrasted magnetic resonance imaging and were given NISS grading score on admission. The patients with exacerbation during 72 h as well as the NISS score adds 2 points or more were classified into the progressive group(24 cases), others were classified into the non-progressive group(36 cases). The diagram of rCBV, rCBF, MTT and TTP were calculated by post-processing of Functool software. The value of the CBF, CBV, MTT and TTP between the infarct center and surrounding tissue were compared and analyzed by two independent sample t test(SPSS 17.0 software). Using contralateral hemisphere as a reference area of interest(ROI), the relative value of the perfusion parameters between affected side and contralateral side was calculated. Results: In both of the progressive and non-progressive group, CBF and CBV values of infarction center were declined, MTT and TTP values were increased, which implied hypoperfusion. Severe hypoperfusion in two groups: brain infarction with the rCBF less than 0.5, MTT increasing more than 1.63, TI more than 4 s. This situation may be the related risk factors that the ischemic brain tissue develops into infarction. The perfusion parameters of relatively normal regional around the lesions can be divided into four types: Type 1, hypoperfusion, markedly increased MTT, the regional decreased CBV, dramatic declined regional CBF; Type 2, the collateral circulation formation, increased MTT, increased or normal regional CBV; Type 3, blood reperfusion, decreased or normal MTT, increased regional CBV, normal or slightly increased regional CBF; Type 4, excessive perfusion information, increased significantly regional CBV and CBF. The types of the progressive group is mainly hypoperfusion, but the non-progressive group includes the four kinds of above. It was convenient for effective master thrombolysis time window and individualized treatment plan to analyze above microcirculation perfusion type in the relative normal around the lesion area. Conclusion: Dynamic susceptibility contrasted magnetic resonance imaging(DSC-MRI) can provide ischemic penum’s brametabolism and superfine morphological information in the early stage of super acute cerebral infarction and guide the clinical treatment, so as to prevent or reduce the occurrence of cerebral infarction finally.

Objective: To study the imaging and pathological features of the primary orbital non-Hodgkin’s lymphoma. Methods: It was a retrospective case series study. Nine patients with the primary orbital non-Hodgkin’s lymphoma were surgically treated in our hospital from January 2008 to December 2014, and had been pathologically confirmed. All patients were performed with ultrasonography, 8 cases with CT, 7 cases with MRI, in which 4 cases with enhanced MRI, 1 case with 18F-FDG PET/CT scan. The data of imaging and pathology were retrospectively analyzed. Results: The inner ball and optic nerve were not invading in all cases. The lesions in 5 of 9 cases located in both of intra- and extra-conal space, and mainly in extraconal one. An intra- and extra-conal involvement of each case. Five cases of lesions involved mainly in peribulbar, 3 cases located behind the ball and 1 case in the eyelid of the ball, destruction of orbital bone was evident in 1 case with diffuse lesions. In 7 of 9 with ultrasonography were considered as occupying or mass, uniform density of soft-tissue mass with local infiltration shaped edges were showed on plain CT film in 6 cases. The signal intensity of the lesions was equal or slightly long T1, T2 homogeneous signal intensity, similar to the extraocular muscles, homogeneous enhancement in enhanced MR scan, intracranial invasion was prompted by the bone destructive lesion. The patient who was performed with postoperative PET/CT, the metabolism of 18F-FDG increased as SUVmax=2.4 in the eyelid, suggesting the lesion residue. According to the new WHO classification of lymphoma: 5 cases of B cell of mucosa-associated lymphoid tissue lymphoma(MALT), each one of diffuse large B-cell lymphoma(DLBCL), follicular lymphoma(FBL), T-cell lymphoblastoid lymphoma(T-LBL) and nature killer/T cell lymphoma(NK/T). Conclusion: The imaging(ultrasound, CT and MRI) of the primary orbital non-Hodgkin’s lymphoma is characteristic, the efficacy of lymphoma surgery can be evaluated by PET/CT, highly aggressive type of malignant pathology with strong invasiveness, the accuracy rate of diagnosis relying solely on imaging is low, the combination of pathology and immunohistochemistry still be required.

DOI:
Objective: To analyse the relationship between maxillofacial imaging distribution characteristics in 99mTc-MDP whole-body bone scanning and skull base invasion in nasopharyngeal carcinoma(NPC) and detect its formation reasons by using SPECT/CT. Methods: Ninety-three patients of NPC underwent 99mTc-MDP whole-body bone scanning and nasopharyngeal SPECT/CT bone scanning before treatment. In the maxillofacial imaging of whole-body bone scanning, a pentagram region with slightly higher radioactivity distribution than skull base was chosen. Except for 2 corners of the pentagram, the rest part was divided into 6 parts, including top part, left connecting part, right connecting part, left shoulder part, right shoulder part and bottom part. Abnormal radioactive concentration in these 6 parts was recorded and made comparisons between them. The SPECT/CT and clinical data were considered as the qualitative standard of skull base invasion. Then the relationship between radioactive concentration distribution characteristics of maxillofacial 6 parts and skull base invasion were analyzed. Results: Eighty-nine cases with 177 lesions were shown radioactive concentration and four cases without in ninety-three cases. Thirty-seven cases with one lesion, twenty-five cases with two lesions and twenty-seven cases with more than three lesions in eighty-nine cases. Skull base invasion was shown 24, 20, 24 cases respectively among that. There was no significantly statistically difference between the amount of lesions and skull base invasion among the radioactive concentration areas(χ2=5.247, P=0.073). In the 6 parts of abnormal radioactivity, skull base invasion was confirmed in top part 75.00%(27/36), left connecting part 90.00%(27/30), right connecting part 86.49%(32/37), left shoulder part 82.61%(19/23), right shoulder part 85.00%(17/20), bottom part 80.65%(25/31). There was no significantly statistically differences(χ2=5.082, P=0.406). In the parts of highest level radioactivity, skull base invasion was confirmed in top part 36.36%(4/11), left connecting part 94.12%(16/17), right connecting part 89.29%(25/28), left shoulder part 66.67%(6/9), right shoulder part 60.00%(3/5), bottom part 73.68%(14/19). The was significantly difference(χ2=16.616, P=0.005). Left and right connecting parts, left and right shoulder parts were no statistically differences respectively(χ2=0.305, P=0.581; χ2=0.062, P=0.803) and merged into connecting part and shoulder part. There was significantly difference among 4 parts(top part, connecting part, shoulder part, bottom part)(χ2=16.400, P=0.001). There was significant statistically difference among top and connecting part(χ2=16.785, P=0.000), top and bottom part(χ2=4.043, P=0.044), connecting and shoulder part(χ2=5.944, P=0.015), and no significantly differences between the rest. Conclusions: In whole-body bone scanning of NPC, some characteristics of the skull base invasion is shown in maxillofacial imaging. These features are helpful to make diagnosis of skull base invasion.

LENG Xiao-ling;HUANG Guo-fu;MA Fu-cheng
DOI:
Objective: To explore the differences of enhanced ultrasound features of the different lesion size, pathological type and histological grading of breast cancer. Methods: Contrast-enhanced ultrasound perfusion modes were analyzed retrospectively in 113 cases of breast cancer patients with 119 lesions. The ultrasonic contrast enhancement characteristics, including enhanced range, enhanced strength, contrast agent distribution, entering sequence, contrast mode, the perforator vessel and perfusion defects etc. were also analyzed. Postoperative pathological types and size, histological grade in breast cancer tissue were collected. To analyze the relationship between contrast-enhanced ultrasonography and lesion size, pathological type, histological grading. Results: Lesions less than 2 cm were more inclined to mild enhancement or moderate enhancement, without blood flow perfusion defect and without perforator; breast cancer lesions more than 2 cm were more inclined to marked enhancement, the existence of perfusion defects and perforator(P<0.05). But whether the range of lesions detected by contrast enhanced ultrasound range is greater than the two-dimensional ultrasound or not, contrast agent distribution characteristics, entry order of contrast agent, imaging sequence model differences were unrelated to lesion size(P>0.05). After contrast enhancement, the ratio of peripheral enhancement, high strength reinforced, peripheral enhancement, speed up and slow down in breast cancer lesions with histological grade Ⅲ level was higher than that of histological grade Ⅰ or Ⅱ tumor(P<0．05). There were no differences in enhanced range, contrast agent entry order, perfusion defects and perforator vessel between the different histological grade of breast cancer(P>0.05). Conclusion: Effect of lesion size and histological grading on contrast enhanced ultrasound features was stronger than the tumor pathological type. Contrast enhanced ultrasound of breast cancer may play a certain role of histological grading.

DOI:
Objective: To evaluate the incidence and morphological characteristics of paratracheal air cyst(PTAC) with 64-row spiral CT, and to improve the recognition ability of PTAC. Methods: Five thousand and five patients underwent thoracic plain CT scan with 64-row spiral CT during a half-year at our institution were retrospectively enrolled to analyze for the presence of PTAC and their morphological characteristics. Results: Four hundred and thirty two patients had PTACs, and the general incidence was 8.63%. The incidence of male was 8.76%(245/2 797), and the incidence of female was 8.47%(187/2 208). There was no significant difference between the male and female(χ2=0.132, P=0.717). Among 432 patients, 404 patients(93.52%) had one air cyst, 23 patients(5.32%) had 2 air cysts, 5 patients(1.16%) had 3 air cysts, with the total of 465 air cysts. All air cysts were immediately adjacent to trachea within 3 mm. The air cysts ranged in size from 1 mm×1 mm to 37 mm×49 mm with mean long axis diameter of (5.6±5.2) mm and short axis diameter of (3.6±3.6) mm. Two hundred and fifty-three air cysts(54.41%) showed direct communication to trachea, and 164 air cysts(35.27%) had septations inside. All air cysts were located at C7~T4 vertebral level including 86.67% of them at T1~T2 vertebral level, meanwhile 96.35% of air cysts were next to the 6~8 o’clock position of trachea. The prevalence of right superior pleural thickening and fibers at right upper lung in patients with air cyst were slightly higher than that in patients without air cyst(42.36%, 44.44% vs 38.12%, 40.04%), but there was no significant statistical difference between them. Conclusion: The incidence of PTAC was quite high. Most of PTACs were single, immediately adjacent to the 6~8 o’clock position of trachea, and located at T1~T2 vertebral level. More than half of PTACs had thin communication to trachea and part of PTACs had septations inside. PTACs have no significant relation with local pleural thickening and fibers at right upper lung.

DOI:
Objective: To investigate the application value of transperineal four-dimensional(4D) ultrasound in female patients with bladder prolapse． Methods: Transperineal 4D ultrasound was performed in 40 cases of normal puerpera and 40 cases of female patients with bladder prolapse. In condition of resting and tension, the real-time movement of pelvic organ was investigated and the relevant parameters of bladder urethral and levator hiatus were measured in median sagital plane and three-dimensional(3D) reconstruct plane. Different types of bladder prolapse were diagnosed according to Green. Results: In median sagital plane, there was no significant difference in the horizontal distence of bladder neck to symphysis pubis between bladder prolapse group and control group(P＞0.05) in rest period, but the angles of retrovesical were larger in bladder prolapse group than in control group(P＜0.05). In tension period, the horizontal distances of bladder neck to symphysis pubis were changed from negative to positive in bladder prolapse group. But the negative were only decreased in control group, the bladder neck movement degrees, retrovesical angles, urethral rotation angles were significantly larger in bladder prolapse group than those in control group(P＜0.05). There were 4 cases typeⅠ, 24 cases type Ⅱ and 12 cases type Ⅲ by Green in bladder prolapse group. In 3D reconstruct plane, the hiatus’ left-right diameter, anteroposterior diameter, circumference and area were measured and determined, all of which were larger in bladder prolapse group than in control group(P＜0.05), but there was no significant difference in the angle of puborectalis between bladder prolapse group and control group(P＞0.05). In tension period, all the indicators of bladder prolapse group were increased significantly compared with the control group(P＜0.05). In prolapse group, puborectalis was not avulsion, the levator-uretha gaps were zygomorphy and the gaps were all less than 25 mm with tomographic ultrasound imaging(TUI) in constraction period. Conclusions: The transperineal 4D ultrasound can be used to dynamic observe bladder prolapse, distinguish different types of bladder prolapse and evaluate the pelvic floor anatomy and function of bladder prolapse, which is worthy of clinical popularization and application．

DOI:
Objective: To evaluate the value of two-dimensional high-frequency ultrasonography and power Doppler imaging(PDI) for judgement of the abnormalities of Achilles tendon in patients with type 2 diabetes mellitus(T2DM). Methods: A total of 60 patients of T2DM were enrolled and divided into two groups: group B(30 cases, the course≤10 years), group C(30 cases, the course>10 years). Thirty healthy subjects were enrolled in group A as normal control. The echotexture of Achilles tendon and blood flow were observed by two-dimensional high-frequency ultrasonography and PDI. The thickness(D1) and width(D2) of each tendon were measured at its starting point, middle point and insertion. Results: The ultrasound imaging of Achilles tendons in group A was shown string like homogeneous hyperechogenicity with clear border with surrounding tissue. The abnormal ultrasound findings, such as hypoechoic areas, heterogenous echogenicity, or indistinct border with surrounding tissue, were more frequently detected in group B and C than group A(all P<0.05). The ratio of calcification of group C was larger than that of group A(P<0.05). There were no significant difference in the ratios of abnormalities of the surrounding tissue among the groups of A, B and C(all P>0.05). At starting point, the thicknesses(D1) of group C were larger than group A(all P<0.05). At middle point, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05), and the thicknesses(D1) of group C were larger than group B(all P<0.05). In the insertion, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05). The blood flow of grade 1 was the most normal sign in the Achilles tendons in the groups of A, B and C. There were no significant difference among the groups of A, B and C in gradings of blood flow. Conclusions: To evaluate the abnormal echotextures, thickening and blood flow of Achilles tendons in the patients of T2DM by Two-dimensional high-frequency ultrasound and PDI are valuable for clinical.

Objective: To explore the treatment of acetabular bone metastases by osteoplasty. Methods: The treatment methods, therapeutic effect and complications of osteoplasty of 12 cases with acetabular bone metastases were retrospectively analyzed. Result: The success rate of operation was 100%. The total effective rate of pain relief attained to 100% and the score of pain dropped to (4.1±2.1) at 1 week after operation. The average score of pain was (3.1±1.2), (2.0±1.4), (1.8±1.7) respectively at 1 month, 3 months and 6 months after operation. There were significant differences in the score of pain between preoperative and postoperative 24 hours, postoperative 1 week and 1 month and postoperative 1 month and 3 months(P<0.05). There was no significant difference in the score of pain between postoperative 3 months and 6 months(P＝0.241). The average score of ability to walk was(0.75±0.72) and (1.9±0.5) at preoperation and 1 week after operation. The average score of ability to walk was (2.5±0.63), (2.7±0.71), (3.0±0.5) at 1 month, 3 months and 6 months after operation, respectively, and there was no significantly different among them(P>0.05). It could effectively stop, reduce and downgrade the use of analgesics. One case was with both lower limbs thrombophlebitis. Conclusion: Osteoplasty is easy to operate and fine security performance, has certain effect to treat acetabular metastases, and which can relieve pain, improve the function of joints and the quality of living.
