ABSTRACT
Objective: To explore the diagnostic value of dual-source CT energy parameters in qualitative diagnosis of metastatic cervical lymph nodes after surgical resection of thyroid papillary carcinoma (PTC). Methods Totally 30 postoperative PTC patients with 74 enlarged cervical lymph nodes were enrolled, including 49 metastatic lymph nodes (metastatic group) and 25 non metastasis lymph nodes (non-metastatic group). In addition, 30 cases with benign enlarged cervical lymph nodes were taken as benign group. All subjects underwent dual-source CT scanning. The iodine concentration value of nonenhanced phase (ICNP), arterial phase (ICAP) and venous phase (ICVP), normalized iodine concentration (NIC) and slope of energy spectrum curve (K) were detected and compared among 3 groups. Results: There were significant differences in ICNP, ICAP, ICVP, NIC and K among 3 groups (all P0.05). Conclusion: Dual-source CT energy parameters can be used to qualitatively diagnose cervical enlarged lymph nodes after surgical resection of PTC.
ABSTRACT
OBJECTIVE@#To explore. HRCT and MRI three-dimensional fast imaging employing steady state ac-quisition(3D-FIESTA) imaging features and clinical characteristics of bilateral large vestibular aqueduct syndrome(LVAS).@*METHOD@#The imaging and clinical features of 14 cases of bilateral LVAS identified over a 5-year periodwere retrospectively analyzed. All patients underwent HRCT and MRI 3D-FIESTA scanning of head and neck;MRI three dimensional reconstructions of internal acoustical meatus were also completed at the same time.@*RESULT@#Audiogram showed mild to moderate hearing loss and was progressive. The cut-off values for the coronal midpointand operculum planes on the HRCT scan to diagnose an EVA were 1. 5 mm and 4. 3 mm respectively; the averagevalue was 2. 4 mm. VA expansion degree were not linked to the degree of hearing loss. MRI showed VA andlymph sac abnormalities. Concomitant image finding was cochlear hypoplasia.@*CONCLUSION@#HRCT and MRI 3D-FI-ESTA are important examinations for accurate diagnosis of LVAS. HRCT can acquire the specific size of reamedVA. MRI and 3D reconstructions of internal acoustical meatus can noninasive show more intuitive display ofLVAS and other inner ear malformations than HRCT.

@#International community-based rehabilitation(CBR) has adjusted the concept to meet the demands of disabled during30-years development. As the latest concept, 2010 CBR Guidelines guides CBR work in countries around the world. Chinese CBR work isfar away from the standards of international CBR concept, so Chinese CBR has to learn international CBR concept and consider Chinese situationto develop CBR with Chinese characteristics. The paper introduces the latest development and contents of international CBR, elaborateshow right and participation reflects in CBR for the disabled in China. On the basis, taking the example of Yuexi program of HandicapInternational, the paper introduces how to integrate resource, promote CBR and social inclusion of the disabled.
