The purpose of this study is to find ways of improving radiology services provided at hospitals through examining current problems of the services and measuring patient satisfaction about them For the purpose, this researcher made a questionnaire survey of 209 patients who used the radiology departments of two university hospitals as tertiary medical institutions located in Busan. The survey was carried out from June 1 to July 30, 2008. Results of the study can be summarized as follows. The patients' satisfaction about the kindness of radiologists was generally low since it Was measured to be scored 3.0 or below in average. This indicates that they were dissatisfied with the equipment and environment. The patients' anxiety about the process of radiology was measured and scored 3.0 or below in average, indicating they generally felt anxious about the process. Factors affecting the above reliability such as their skillfulness, qualification, persuasiveness and expertise were found positively correlated with the patients' satisfaction about the radiologists. To realize Better radiological department services, in conclusion, radiologists are required to resort to conventional practices of radiology no longer, and reconsider current radiological technologies. They are also required to firmly establish their pride as a professional, and make best efforts to keep pace with this era of rapid scientific development by constantly training themselves.

The supply of medical services using high-priced medical equipment is increasing due to the medicalization of medical science. The level of medical knowledge of medical consumers and the ability to select medical institutions are required to provide high quality medical services because of the popularization of medical information. As the attitudes of medical consumers toward medical institutions change, medical institutions also need to change their perception to improve customer satisfaction. The purpose of this study is to analyze the difference of medical service satisfaction according to the medical knowledge about the utility of PET / CT in order to change the consciousness structure of medical service. The results of this study showed that both medical satisfaction and environmental satisfaction were high in those who had medical knowledge about their own illness and the usefulness of PET / CT. Therefore, medical institutions will need a practical medical service countermeasures to provide medical information by noticing the changes in perception of the medical knowledge of medical consumers, rather than providing formal medical services.

In this paper, we present the Tele-consulting system of radiology, which uses the communication network as asymetric satellite data communication system. The asymetric satellite data communication system uses receive-only satellite links or data delivery and PSTN(Public Switched Telephone Network) modem or N-ISDN(Integrate Services Digital Network) for communication. The satellite communication linking shows the very high-speed performance than 28.8kbps modem linking. The satellite linking is 5 - 10 times aster than the modem linking. Consequently, we get the conclusion that our system is suitable or tele-radiology and telemedicine.

Objective: To assess the noncontrast two-dimensional single-shot balanced turbo-field-echo magnetic resonance angiography (b-TFE MRA) features of the abdominal aortic aneurysm (AAA) status following endovascular aneurysm repair (EVAR) and evaluate to detect endoleaks (ELs). Materials and Methods: We examined four aortic stent-grafts in a phantom study to assess the degree of metallic artifacts. We enrolled 46 EVAR-treated patients with AAA and/or common iliac artery aneurysm who underwent both computed tomography angiography (CTA) and b-TFE MRA after EVAR. Vascular measurements on CTA and b-TFE MRA were compared, and signal intensity ratios (SIRs) of the aneurysmal sac were correlated with the size changes in the AAA after EVAR (AAA prognoses). Furthermore, we examined six feasible b-TFE MRA features for the assessment of ELs. Results: There were robust intermodality (r = 0.92-0.99) correlations and interobserver (intraclass correlation coefficient = 0.97-0.99) agreement. No significant differences were noted between SIRs and aneurysm prognoses. Moreover, "mottled high-intensity" and "creeping high-intensity with the low-band rim" were recognized as significant imaging findings suspicious for the presence of ELs (p < 0.001), whereas "no signal black spot" and "layered high-intensity area" were determined as significant for the absence of ELs (p < 0.03). Based on the two positive features, sensitivity, specificity, and accuracy for the detection of ELs were 77.3%, 91.7%, and 84.8%, respectively. Furthermore, the k values (0.40-0.88) displayed moderate-to-almost perfect agreement. Conclusion: Noncontrast MRA could be a promising imaging modality for ascertaining patient follow-up after EVAR.

Teleradiology is the electronic transmission of radiologic images from one location to another for the purpose of interpretation and/or consultation. Today, images can be easily transmitted to another location using the high-speed internet. In medical area, teleradiology has developed rapidly in recent 10 years due to the imbalance between the demand and availability of diagnostic services. However, teleradiology in dentistry is still inactive. I would like to overview the current teleradiology system, and discuss the necessity and the potentiality.

Tobacco use is described as the single most preventable cause of morbidity and mortality globally, with the World Bank predicting over 450 million tobacco-related deaths in the next fifty years. In India, the proportion of all deaths that can be attributed to tobacco use is expected to rise from 1.4% in 1990 to 13.3% in 2020 of which smoking alone will cause about 930,000 adult deaths by 2010. Many studies have shown that counseling from a health professional is an effective method of helping patients quit the tobacco habit. Tobacco cessation needs to be urgently expanded by training health professionals in providing routine clinical interventions, increasing availability and subsidies of pharmacotherapy, developing wide-reaching strategies such as quitlines, and costeffective strategies, including group interventions. The WHO Framework Convention on Tobacco Control (FCTC) emphasizes the vital contribution of participation of health professional bodies, as well as training and healthcare institutions in tobacco control efforts. Dentists can play an important role in helping patients quit using tobacco. One of the key strategies to reduce tobacco-related morbidity and mortality is to encourage the involvement of health professionals in tobacco-use prevention and cessation counselling. The dental office is an ideal setting for tobacco cessation services since preventive treatment services, oral screening, and patient education have always been a large part of the dental practice.

In the field of healthcare, the conventional sterilization treatments have been replaced by irradiation methods which are in accordance with internationally well established quality standards. The quality control in radiation sterilization assures that the absorbed dose of the irradiated material is in agreement with its requirements and standards. The electron beam irradiation requires technical assessments of more process parameters than gamma irradiation does. Korea has witnessed wide uses of electron accelerators since early 2000 but there hasn't been research experiences relating to quality system in accordance with international standards. The new large scale e-beam irradiation system with the specification of 10 MeV, 8 kW was installed and operated in 2008 by Seoul Radiology Services Co. It consists of the electron accelerator, product handling system, safety, documentation and control subsystems into an integrated system to meet the requirement of the Good Manufacturing Practice such as process quality assurance and management of product tracking records. To implement the international standard such as EN ISO11137, it is necessary to understand the purposes aimed in the standard and carry out the tests following the procedures required. This study presented the specification of the e-beam facility and showed what its design requirements and features are. The test results on a variety of process parameters were presented and validated it they are within the required limits.

This study presented a mediation strategy of admittance quota of four year and three year colleges raising radiology technicians by investigating the demand and supply related literature for Radiological Technologists, a type of health and medical services personnel. Oh Yeong-ho et al.'s study on mid and long term supply system for health and medical services personnel resources, excess supply of 1,134~2,052 Radiological Technologists in 2015 was predicted and excess supply of 12,632~14,196 Radiological Technologists are to be expected in 2030. To settle excess supply of Radiological Technologists, Supernumerary quota over the entrance students of institutions raising Radiological Technologists should be less than 5% to reduce applicants for Radiological Technologists to be 308 people, reduce 387 applicants for radiology technicians every year by unifying three year colleges raising Radiological Technologists with four year colleges into education period unification, evaluate education conditions of colleges to restrict those colleges lacking the minimum requirements from getting eligibility for take the examination for Radiological Technologists by establishing tentatively 'Korean Institute of Radiologic Education and Evaluation.' For this, it is necessary to obtain cooperation from health and medical services personnel organizations in pertinent fields as well as related organizations of Radiological Technologists.

The purpose of this paper is to describe the transition of a 1,100 beds teritary hospital from 50% softcopy operation to full PACS operation. For the past 2 years, radiologists and clinicians have been using PACS to provide softcopy services to the outpatient clinics and inpatient wards of orthopedics surgery, neurosurgery and neurology as well as emergency room, surgical intensive care unit, medical intensive unit, pediatrics intensive care unit and neonatal intensive care unit. The examinations requested by these departments account for about 50% of hospital's radiological exams. In September 1996, we began the second phase of PACS implementation and installed additional workstations (102) in the remaining wards and clinics, interfaced to PACS additional imaging modalites, and increased the capacity of both the image server (256 Gbytes) and optical juke boxes (3 Tbytes). As of January 1997, we are in the final phase of moving away from conventional film system to full PACS operation.
