ABSTRACT

Objective To observe the value of CT spectral imaging in assessment of synovial hemosiderin deposition (SHD) in the knee joint in patients with hemophilic arthropathy (HA).Methods Twenty-five HA patients (40 assessable knees) underwent CT spectral imaging and MR scanning.According to the MRI international prophylaxis study group (IPSG) score of SHD,the knees were divided into mild group and severe group.CT value,iron (water) concentration (FeC),water (iron) concentration (WC),effective atomic number (Eff-Z) and average spectral curve slope (aSCS) of SHD area were measured and calculated,respectively.Meanwhile,the adjacent semi-membrane muscles in the same slice were taken as controls.The spectral parameters of CT were compared with One-Way ANOVA,and ROC curves were plotted to obtain the spectral parameters and the optical diagnostic threshold of SHD.Results CT value,FeC,and aSCS of SHD area were statistically significant among three groups (F=148.08,307.88,7.80,364.62 and 261.50,P<0.01),and the differences of parameters between any two groups except WC were statistically significant (all P<0.05).The area under ROC curve of SHD evaluated with aSCS was the largest,and the thresholds for the diagnosis of severe and mild SHD of aSCS was 1.84 and 0.42,respectively.Conclusion Multiple parameter analysis of CT spectral imaging is of great value for assessment of the severity of SHD in the knee joint in HA patients,therefore having important clinical significance.

ABSTRACT

Objective To explore the clinical effect of transvaginal repair of cesarean scar diverticulum (CSD). Methods Totally 64 patients of CSD in the First Maternity and Infant Hospital, Tongji University between Mar. 2013 and Sept. 2014 underwent transvaginal repair of CSD were reviewed retrospectively and followed. Result All the patients had a prolonged period, and the duration was (14.8± 3.5) days; all the patients were received the transvaginal repair of CSD, there was no intra-operative complications, the procedures were successfully performed in all patients. The mean operation time was (67± 12) minutes, the mean blood loss was (53±32) ml, and the mean length of hospital stay was (4.0±1.1) days. All patients were followed after the operation, the duration of menstruation was (8.1 ± 3.5) days shorter in average, which was statistically significant (P<0.01);the operation effective rate was 94%(60/64) to assess the clinic syptoms, the operation effective rate was 95%(61/64) for anatomic assessment. The distance of the CSD from the serosa became thicker after surgery significantly, the distance was thicker (3.4 ± 0.4) mm compared with preoperation (P<0.01). Conclusions Transvaginal repair of CSD offers minimal invasiveness, good exposure and accurate resection. It is worth to be popularized in the treatment of patients with CSD.

ABSTRACT

Objective To investigate the effect of special CT monochromatic images on improving imaging quality in Budd-Chiari Syndrome.Methods 40 patients with Budd-Chiari Syndrome underwent CT venography (CTV)with gemstone spectral imaging (GSI).Using the optimal contrast to noise ratio (CNR)curve of GSI software,the optimal CNR monochromatic images of the infe-rior vena cava and hepatic vein were chosen.The CT value of the intrahepatic segment of inferior vena cava,hepatic vein and the same level liver tissue were measured,and the CT value of the same region were measured on 140 kVp mixed energy images and 70 keV images.CNR on the optimal monochromatic images,the 140 kVp mixed energy images and 70 keV images were calculated respectively,and the image quality of the optimal monochromatic image,the 140 kVp mixed energy images and 70 keV images were subjective scoring.One-way ANOVA was used for statistical analysis using SPSS1 7.0 software.Results The optimal keVs from monochromatic images were distributed at 40 keV (50%)and (5 1 ± 1 )keV (50%)for IVC and 40keV (25%)and (53 ± 3)keV (75%)for HV.The CNR and CT value and subjective score of IVC/HV got from the optimal monochromatic images were signifi-cantly higher than those from 140 kVp mixed energy images and 70 keV images respectively(P <0.01 ).Conclusion The optimal monochromatic images provide higher image quality of IVC and HV in patientswithBudd-Chiari syndrome.
