DOI: 10.12117/jccmi.2018.09.001
Objective: To explore objective criteria which are suitable for clinical application by comprehensive analysis of unilateral hyperdense middle cerebral artery sign(HMCAS) on non-enhanced computed tomography(NECT). Methods: One hundred sixteen patients with hyperacute cerebral infarction were retrospectively evaluated. The presence of HMCAS was evaluated between inter- and intra-observers. K value was calculated. The cut off value of MCA attenuation and MCA ratio(the affected side/the healthy side) in the HMCAS(+) and HMCAS(-) was measured through the ROC curve in all patients with hyperacute cerebral infarction. The sensitivity and specificity was analyzed. Results: The interobserver and intraobserver agreement were substantial(K value of 0.82 and 0.86, respectively) and increased to almost perfect(K value of 0.95) when the reader was provided with clinical information. MCA attenuation≥40 HU and MCA ratio≥1.2 was the best threshold for HMCAS recognition. When both MCA attenuation≥40 HU and MCA ratio≥1.2 were satisfied, sensitivity(91.23%) and specificity(100%) were the highest relative to other standards. Conclusion: It is effective and feasible to evaluate the unilateral HMCAS on NECT images by combining with clinical history. MCA attenuation≥40 HU and MCA ratio≥1.2 was the best threshold for HMCAS recognition, which is suitable for application in daily clinical practice.

DOI: 10.12117/jccmi.2018.09.002
Objective: The diagnostic value of real-time shear wave elastography(SWE) to infants congenital muscular torticollis(CMT) and the clinical application of SWE in assessing the no-surgical treatment effect of children’s CMT were discussed. Methods: One hundred and two cases of suspected children with CMT(outpatient in our hospital from Jan. 2015 to June. 2017) were collected. All of them were examined by ultrasound and SWE was used to collect the elastic modulus data of sternocleidomastoid muscle on the affected side and the healthy side. After that, the children patients’ therapeutic process was followed up. The no-surgical treatment mainly includes massage and ultrasonic short wave physiotherapy. When a follow-up to three months was fulfilled, ultrasound reexamination was performed and the elastic modulus data of the children patients’ sternocleidomastoid muscle was recollected. Results: In the 102 cases of children patients, 76 cases were diagnosed with CMT. The area under ROC curve of diagnosing CMT by SWE was 0.844, and the diagnostic threshold was 182 kPa, and the sensitivity was 84.2%, and the specificity was 73.1%, and the positive predictive value was 90.1%, and the negative predictive value was 61.2%, and the Youden index was 0.573. To the children patients with CMT, a comparison of the elastic modulus data between sternocleidomastoid muscle on the affected side and the healthy side was performed, and the difference is statistically significant(P<0.05). Through the reexamination after no-surgical conservative treatment, the average elastic modulus value of sternocleidomastoid muscle on the affected side was significantly reduced, and the difference is statistically significant(P<0.05). Conclusion: Real-time SWE yields theoretical foundations to the diagnosis and the treatment effect evaluation of infants CMT. It embraces a certain value of popularization and application.

DOI: 10.12117/jccmi.2018.09.013
Objective: The aim of this study was to demonstrate stability and accuracy in tumor semiquantitative assessment of the integrated PET/MR by analyzing difference and correlation between PET/CT SUVmax and PET/MR SUVmax.  Methods: Fifty-seven patients(22 males, 35 females, average age (54±12) years), who underwent same day whole-body PET/CT and PET/MR in Shengjing Hospital Affiliated to China Medical University, the time interval between the two scans was (78±35) minutes. Patients underwent the whole-body PET/CT and PET/MR from the base of skull to upper thighs, TOF-PET technique of GE company was used to reconstruct images and SUVmax was obtained by fusion images to delineate ROI of lesions and some normal tissues. The difference analysis of SUVmax were performed with Paired t test and the correlation was analyzed with Spearman correlation analysis. Results: 97 hypermetabolism lesions were detected by PET/CT, 100 hypermetabolism lesions were detected by PET/MR, a total of 96 hypermetabolism lesions were detected by two modalities. The PET/MR SUVmax of lesions was significantly higher than that of PET/CT SUVmax(P<0.0001) in the case of PET/CT and following PET/MR. The PET/MR SUVmax of most normal tissues significantly lower than that of PET/CT(P<0.0001), only the PET/MR SUVmax of psoas was slightly higher than that of PET/CT, but there was no statistical difference(P=0.056). The ratios of PET/MR SUVmax of the lesion and the normal tissues were significantly higher than PET/CT(P<0.0001). There were significant correlations of SUVmax between PET/MR and PET/CT for lesions(r=0.92, P<0.0001) and for normal tissues(lung r=0.64;liver r=0.87; spleen r=0.73; psoas r=0.57, P<0.0001). Conclusions: The SUVmax of PET/MR in tumor was significantly higher than that of PET/CT, which may be due to PET/MR technical advantages and delayed glucose uptake by malignant lesions. PET/MR and PET/CT SUVmax highly correlated, suggesting that integrated PET/MR on semiquantitative analysis of malignant tumor lesions has a very good stability and accuracy.

DOI: 10.12117/jccmi.2018.09.014
Objective: To investigate the application value of low tube voltage in combination with iterative model reconstruction(IMR) in lower extremity CT angiography(CTA). Methods: Forty-four patients were randomly divided into experimental group(n=22) and control group(n=22). All the patients underwent CTA with　automatic tube current modulation. The patients in experimental group(group A) were scanned with 80 kVp tube voltage, 75 mL of contrast agent, flow rate at 3 mL/s and IMR. The patients in control group(group B) were scanned with 120 kVp, 100 mL of contrast agent, flow rate at 4 mL/s, and filtered back projection(FBP). CT values of vessel were measured on bilateral lower extremity arteries of the axial images, including aortic bifurcation, common femoral artery, middle superficial femoral，proximal popliteal artery and tibiofibular trunk artery. The standard deviation(SD) of CT value of vessel lumen was defined as image noise. The SNR and CNR were calculated. The subjective image quality was scored. The results of CT volume dose index(CTDIvol) and dose length product(DLP) were recorded. Results: The CT values、SNR and CNR were higher in group A than group B(P<0.01). There was no difference in subjective image quality between the two groups(P>0.05). The CTDIvol and DLP of group A were lower than that of group B(P<0.01). Compared with group B, the iodine load decreased by 25%. Conclusions: Lower extremity CTA with low tube voltage and IMR can provide good image quality for clinical diagnosis with a significant reduction in radiation dose and the iodine load.
