DOI:
Objective: To study the correlation between the anatomic variations of the ostiomeatal complex(OMC) and sinusitis through the observations by multi-slice spiral CT(MSCT). Methods: 291 subjects who were examined with MSCT in our hospital were randomly selected in this study. The anatomic variations of the OMC were observed and recorded. Statistical analysis was done by Chi-square test with SPSS 15.0. Then, occurrence in the non-sinusitis and the sinusitis group was compared. Result: The OMC’s structure, variations and lesion could be clearly shown by the bone reconstruction and multiplannar reconstruction. The variation rate of sinusitis group was higher than non-sinusitis group. There is significant difference between the sinusitis group and non-sinusitis group with the movement and curl of uncinate, hyperpneumatization of agger cells and ethmoidalis(P＜0.05). Conclusion: The OMC’s structure, variations and lesions can be clearly observed by using multiplannar reformation techniques of MSCT. There is an intimate relationship between the anatomic variations of OMC(movement and curl of uncinate, hyperpenumatization of agger cells and ethmoidalis) and the morbidity of sinusitis.

DOI:
Objective: To analyse the clinical characteristics of patients with coronary artery tortuosity and the relationship between tortuous vascular distribution and impaired left ventricular diastolic function. Methods: Forty-seven cases of coronary artery angiography patients with undefined stenosis and coronary artery tortuosity were detected by 640 multi-detector spiral CT and echocardiography. Results: Forty-seven cases of coronary artery tortuosity patients, including 22 cases of males and 25 cases of females, accompanied with hypertension of 35 cases, 141 cases of tortuous vascular segments were found, including 25 mild, 19 moderate and 3 severe, and often occurred in distal segment of left interior descending, distal segment of circumflex artery, left ventricular posterior branch. The left ventricular diastolic function were impaired in 38 patients, including 38 cases of E/A<1, 7 cases of E/A=1, and 2 cases of E/A>1. Conclusion: There is a certain relationship between coronary artery circuity and hypertension. Circuitous blood vessels are mainly occurred in feeding arteries of the left ventricular myocardial, and many patients with coronary artery circuity combined with decreased left ventricular diastolic function. The two reasons result in a poor capacity of coronary blood flow reserve, which is an important reason for the patients with similar symptoms of coronary heart disease.

DOI:
Objective: To evaluate the characteristics and regularity of echocardiographic in the diagnosis of rupture of aortic sinus aneurysm(RASA) accompanied with the ventricular septal defect(VSD), by analyzing the relationship between the RASA and VSD. Methods: The features of two dimension ultrasound and color Doppler flow imaging of 59 patients with ASA were retrospectively analyzed and compared with surgical results. Results: In the 59 patients, 51 patients with ASA were originated from right coronary sinus, ruptures were observed in 46 cases; and VSD were observed in 39 cases(66%); and aortic insufficiency were observed in 26 cases(44%)(in which aortic valve prolapse were observed in 9 cases(15%)). The location, size, rupture, drainage chamber of RASA diagnosed by ultrasonography were all confirmed by the surgical results; the size of VSD was underestimated by ultrasonography in 3 cases, and 2 VSD cases were misdiagnosed(stem inferior type). Conclusions: Echocardiography can diagnose RASA accompanied with VSD accurately, but VSD could be possibly misdiagnosed or underestimated ventage size. In order to improve diagnose more accurately and reduce misdiagnose and missed diagnosis, it is very important to observe the echocardiographic characteristics carefully and precisely by combined two dimension ultrasound and color Doppler flow imaging. This method could be as an optimizing in the diagnosis way to diagnose RASA combined with VSD.

DOI:
Objective: To evluate the CT imaging features of hepatic inflammatory myofibroblastic tumor(HIMT), so as to improve its diagnostic accuracy. Materials and Methods: The clinical and CT imaging findings of 6 cases of HIMT which confirmed by pathology in our hospital were analyzed retrospectively, including 4 males and 2 females, aged from 48 to 59 years old, mean age was 43 years old. Pre- and post-contrast CT images were examined for all six cases. Results: Five of six cases were single lesion, the other one was multiple. Clear margin was in four cases and unclear margin in two cases. Three cases were located in the left lobe of liver, 2 cases were in the right lobe of the liver and 1 case was located both the left and right lobe. In the pre-contrasted enhancement CT scan, heterogeneous(n=2) or homogeneous(n=4) hypo-density were shown in six cases. No enhancement(n=2) or mild/moderate enhancement(n=4) was shown in arterial phase respectively. Delayed enhancement was shown in the portal phase(n=6) and the delayed phase(n=5). Moreover, on the arterial phase image, feeding artery were shown in one case, having patchy enhancement around it in one case. The dilatation of the intra-hepatic bile duct was seen in one case. Conclusion: The dynamic contrast enhancement CT features of HIMT are multiple characteristic, which correlate with its pathologic findings. But the final diagnosis relies on pathology and immunohistochemistry examination.

DOI:
Objective: To investigate enhancement characteristics of renal angiomyolipoma with minimal fat(AMLmf) on routine biphasic abdominal MSCT. Methods: Fifteen cases of AMLmf were reviewed retrospectively which confirmed by pathology from February 2007 to April 2013. The CT features of AMLmf were analyzed, and the CT value of lesions and normal nephric cortex in pre-contrasted CT scan, arterial phase, and venous phase were calculated and compared. Enhancement degree of lesions and enhancement ratio between lesions and nephric cortex in arterial phase, venous phase were calculated and compared in our study. Results: The attenuation of the mass was higher than normal nephric parenchymal in plain scan, however, there was no significant difference between them(P=0.068). In arterial phase and venous phase, the enhancement of lesion was avid, but the CT values of mass were lower than nephric cortex significantly(P value was 0.014, 0.001). There were no significant difference in enhancement degree of lesion and enhancement ratio between lesion and nephric cortex in both arterial phase and venous phase(P＞0.05). The enhancement model of AMLmf at biphasic MSCT was plateau curve, and the nephric parenchymal was persistent enhancement type. Conclusions: The enhancement of AMLmf on biphasic abdominal MSCT was avid and the enhancement degree of lesion was similar in both arterial and venous phase, the enhancement of lesion was significant lower than nephric cortex. The enhancement model of AMLmf on biphasic abdominal MSCT was plateau curve.

Methods: Ninety-five patients underwent CTU scanning on GE Discovery HD CT were divided into 2 groups, including 57 cases in control group(group A) and 38 cases in study group(group B). Group A was given conventional scanning program: 120 kVp, 3D auto mA and noise index 15 HU, scan time 0.8 s, thickness 5 mm, pitch 1.375∶1, the image processing 50% ASIR, reconstruction Stnd, thickness 1.25 mm, the amount of contrast agent are 100 mL, injection speed of 4.0 mL/s. Group B was given GSI scanning mode: 80/140 kVp fast switching, 275 mA. Other parameters were same with group A, reconstruction 85 keV, 1.25 mm thickness of a monochromatic image, the amount of contrast agent was 300 mgI/kg, speed of contrast agent injection was volume(mL)/30 s. Iohexol were used in two groups as contrast agent (iodine content of 350 mg/mL). CT values and SD value(noise) of gluteus maximums and contrast agent in bladder were measured in both two groups for calculation of CNR. Patients’ weight, volume dose index CTDIvol and DLP were recorded. CT values, SD values, CNR, CTDIvol, DLP, the amount of contrast agent and injection rates were compared between two groups using independent sample t test. The quality of VR and MIP images were evaluated by two radiology physicians with five years of experience using five-point scale, and the results of the consistency test using Kappa analysis, subjective rating were compared by Mann-Whitney U. Results: There were no significant difference of patients weight and SD value between two groups. The mean CT value of bladder contrast agent in group B (569.73±265.74) was statistically higher than group A(437.37±227.50)(P<0.05). The value of CNR in group B(40.14±22.35) was statistically higher than group A(29.23±19.03)(P<0.05). The value of CTDIvol, DLP, amount of contrast agent and injection rate of group B were statistically lower than group A(P<0.05). No significant difference in the image quality evaluation was observed between two groups(4.65±0.57 vs. 4.68±0.56). Conclusions: Individual contrast dosage and low radiation dose CTU imaging using single energy CTU imaging can effectively reduce the radiation dose and the amount of contrast agent and improve the beam hardening artifact images.

Methods: Retrospective analyse 58 women diagnosed with placenta increta from January 2006 to January 2014 at affiliated Hospital of Wenzhou Medical University, all patients were confirmed by clinical and/or pathology after postpartum, and all were given Doppler ultrasound and MRI to monitor placental growth situation. The sensitivity and accuracy of Doppler ultrasonography and MRI for prenatal diagnosis of placenta increta were analysed. Results: In 58 patients with placenta increta, Doppler ultrasound diagnosis of 31 cases, coincidence rate was 53.4%(31/58), MRI diagnosis of 39 cases, coincidence rate was 67.2%(39/58). Two kinds of diagnostic methods have no statistical significance(P＞0.05). Combined diagnosis coincidence rate was 82.8%(48/58). Three kinds of diagnostic methods have statistical significance(P＜0.05). Patients with placenta are located in the back wall, Doppler ultrasound diagnosis of 14 cases, coincidence rate was 43.8%(14/32), MRI diagnosis coincidence rate was 57.1%(23/32). Two kinds of diagnostic methods have statistical significance(P＜0.05). When the signs of thickening of the placenta, disappear of placenta back gap and so on were detected, the diagnosis coincidence rate was 48.3%(28/58), single sign was difficult to determine whether it was placenta implantation. When there were direct signs showed on MRI, the diagnosis coincidence rate was 53.4%(31/58), while the indirect signs of the diagnosis coincidence rate was only 13.8%(8/58), the difference was statistically significant(P＜0.05). Conclusion: When placenta locates in the uterus back wall, MRI is more accurate than the Doppler ultrasound examination it can be used as an important supplement of the Doppler ultrasound examination. When many signs of placenta increta appeared on ultrasonography and direct signs appeared on MRI, it should be considered of placenta increta.

X-ray was inferior to CT(χ2=18.576, P<0.001; χ2=13.069, P<0.001) and MRI(χ2=24.605, P<0.001; χ2=31.112, P<0.001) in finding a tophus joint and cystic relevant section under the surface of the joints. There was no significant difference between CT and MRI in finding a tophus joint and cystic relevant section under the surface of the joints(χ2=0.466, P=0.495; χ2=3.211, P=0.073). However, MRI was superior to CT in finding synovial thickening and ligament erosion, cartilage erosion, joint effusion and muscle edema around the joint gap(χ2=19.790, P<0.001; χ2=11.568, P<0.001; χ2=13.297, P<0.001; χ2=6.720, P=0.01). Conclusion: X-ray, CT and MRI all could be used for the diagnosis of gouty arthritis. The diagnosis of MRI was superior to the others, but CT is characterized by specificity of tophus and X-ray could be employed in patients with comparison of severe lesion.
