The research on integrity and standardization of structured MRI report for rectal cancer / 实用放射学杂志

Objective To assess the integrity and standardization of structured MRI report for rectal cancer of the affiliated hospital of qingdao university,referring to National Comprehensive Cancer Network (NCCN) guidelines for colorectal cancer (Version 2015)and foreign authoritative research results,and put forward some suggestions to improve the quality.Methods A total of 110 structured MRI reports of 107 patients with rectal cancer were included in the study.The inclusion rates of 8 indexes were evaluated,including tumor site,distance from upper to lower border of tumor (DIS),tumor invasive depth (T staging),anal complex staging (A staging),nodal staging (N staging),the circumferential resection margin (CRM),extramural vascular invasion (EMVI) and metastases staging (M staging),which were compared with research results of structured reports in abroad by using Pearson chi-square test.Results There was a significant difference in the description of N staging (x2 =8.424,P＜0.05) between our research and foreign study,in 110 structured MRI reports.There was no significant difference in the description of tumor site (x2 =0.00,P＞0.05),DIS (x2 =0.041,P ＞0.05),T staging (x2 =3.256,P＞0.05) and CRM(x2 =2.957,P＞0.05) between the two groups.A staging,EMVI and M staging were not described.Conclusion Our structured MRI reports for rectal cancer basically meet international research standards.Structured MRI reports have advantages,and deserve to be further studied and promoted.

Telediagnóstico para eletroencelografia em Santa Catarina / Telediagnóstico for electroencephalogram in Santa Catarina

No Brasil, estima-se que em torno de 5 a 7% da população apresentará uma crise epiléptica ao longo da vida. O Eletroencefalograma é um método fundamental para diagnóstico de epilepsia. Este artigo apresenta o desenvolvimento de um protótipo integrado ao Sistema Catarinense de Telemedicina e Telessaúde, com o objetivo de dar suporte a exames de Eletroencefalograma com envio, emissão de laudos e visualização a distância. São utilizados CID-10 e Descritores em Ciências da Saúde como linguagem de indexação de laudos a fim de gerar estatísticas em pesquisas futuras. O sistema está implantado em quatro unidades de saúde no município de Florianópolis. Os laudos são emitidos por um médico especialista da própria rede municipal e os exames são enviados à rede de Telemedicina. Com o uso desta metodologia é possível facilitar o dia-a-dia dos médicos, técnicos e pacientes com acessos mais rápidos e eficientes, melhorando a qualidade de vida dos pacientes.

In Brazil is estimated that around 5-7% of the population will have an epileptic seizure lifelong. The electroencephalogram is a fundamental method for the diagnosis of epilepsy. This paper presents the development of an integrated prototype called Santa Catarina Telemedicine System, in order to support electroencephalogram exams with sending, issuing reports and online viewing. We used ICD-10 and Health Sciences Descriptors as reports indexing language, in order to generate statistics in future research. The system is deployed in four health units in the Florianopolis city. A medical specialist that works in own municipal network issues the reports and the exams are sent to the Telemedicine network. Using this new methodology we can facilitate the day-to-day lives of doctors, technicians and patients with faster and more efficient, Improving Quality of Life for Patients.

Construction and Standardization Research on Hospital Medical Imaging Data Center Based on Clinical Data Repository / 中国医学影像学杂志

Hospital image information system is evolving from department-oriented to patient-oriented. This paper introduces the implementation of Beijing University People's Hospital image data center. The ideas, approaches and the technological standards for image data center's system integration are proposed. Additionally, the problems in practical application and the outlook for this system are discussed.

Analysis of CT radiation dose based on radiation-dose-structured reports / 中华放射医学与防护杂志

Objective To analyse the CT radiation dose statistically using the standardized radiation-dose-structured report (RDSR) of digital imaging and communications in medicine (DICOM). Methods Using the self-designed software, 1230 RDSR files about CT examination were obtained searching on the picture archiving and communication system ( PACS ) . The patient dose database was established by combination of the extracted relevant information with the scanned sites. The patients were divided into adult group (over 10 years) and child groups (0-1 year, 1-5 years, 5-10 years) according to the age. The average volume CT dose index ( CTDIvol ) and dose length product ( DLP) of all scans were recorded respectively, and then the effective dose ( E) was estimated. The DLP value at 75% quantile was calculated and compared with the diagnostic reference level ( DRL) . Results In adult group, CTDIvol and DLP values were moderately and positively correlated ( r=0?41 ) , the highest E was observed in upper abdominal enhanced scan, and the DLP value at 75% quantile was 60% higher than DRL. In child group, their CTDIvol in group of 5-10 years was greater than that in groups of 0-1 and 1-5 years ( t=2?42, 2?04, P<0?05);the DLP value was slightly and positively correlated with the age (r=0?16), while E was moderately and negatively correlated with the age ( r = -0?48 ) . Conclusions It is a simple and efficient method to use RDSR to obtain the radiation doses of patients. With the popularization of the new equipment and the application of regionalized medical platform, RDSR would become the main tool for the dosimetric level surveying and individual dose recording.
