As medical insurance had been implemented for Magnetic Resonance Imaging (MRI) from January 1, 2005, this study investigated whether there had been any change in the amount of the medical care utilization of patients who undertook MRI before and after the insurance coverage, and was to examine factors affecting the amount of medical care utilization of MRI. Data were collected from patients who undertook MRI before and after the insurance coverage for a year at a general hospital in Kyeanggi-do. $X^2$ and t-test were used for the analysis of their general characteristics, the number of MRI, and its medical costs before and after the insurance coverage, and hierarchical multiple regression analysis for the factors affecting the amount of the medical care utilization of MRI. The results of this study were as follows. First, the number of MRI after the insurance coverage was significantly decreased. Second, there was no significant difference in the total medical costs of MRI after the insurance coverage, but a significant difference was found in patient's share of medical costs. Third, six variables were found to be affecting the amount of the medical care utilization of MRI, and the variables showed to lead the number of MRI decrease after the insurance coverage. These six factors explained 21.4% of the total number of MRI. As MRI had been covered by insurance, the use of MRI and patient's share of the costs were deceased, but the total medical costs were not affected. Reasons for that could be found in that MRI insurance, different from the case of CT insurance coverage, was allowed not to cover some items and the kinds of diseases subjected to the insurance coverage were extremely limited, lowering insurance prescription rate. In addition to that, the average medical cost of MRI was not changed after the insurance coverage. Therefore, as future measures for the MRI insurance, coverage, it should be considered to allow insurance coverage to no coverage items and to expand the scope of benefit coverage, or to lower patient's share of the costs. Furthermore, researches should be done to explore how recipients will act and how suppliers will react if the coverage is expanded, including expanding the scope of coverage and reducing patient's share of the costs, as well as to conduct research on its economic analysis according to case mix.

In order to analyze the shifts in the volume and profits of Computed Tomography(CT) and Magnetic Resonance Imaging(MRI) utilization for a year before and after the implementation of insurance coverage for CT, this study has been undertaken examining CT and MRI cost data from 'Y' University Hospital situated in Seoul, Korea. Following are the results of this study: 1. The medical insurance payment for CT, implemented on January 1, 1996, increased CT utilization from January 1996 to April 1996 due to low insurance premiums: however, from May 1996 the number of CT cases significantly decreased as a result of strengthened medical cost reviews and the new 'Detailed standards for approval of CT' announced near the end of April 1996 by the insurer. 2. Since the implementation of insurance coverage for CT, CT fee reduction rates for reimbursements by the insurer to the hospital were 50% and 40% for January and February, respectively, and 31% and 15% for March and April. A significant point in the lowering of the reduction rate was reached in May at 11%; furthermore, since June the reduction rate fell below the average reduction rate for reimbursements for all procedures. If the 'Detailed standards for approval of CT' had been announced before the implementation of insurance coverage for CT, CT utilization would not have been so high due to the need to meet those 'standards'. In addition, loss of hospital profits resulting from the reduction for reimbursements would not have occurred. 3. The shifts in MRI utilization showed that there was no particular change with the beginning of insurance coverage for CT, and the introduction of the 'Detailed standards for approval of CT' made MRI utilization increase because MRI is free of restrictions imposed by the insurer. 4. The relationship between CT utilization and MRI utilization showed that they were supplementary to each other before insurance coverage for CT, but that CT was substituted for MRI because of strengthened medical cost reviews after t~e beginning of insurance coverage for CT. 5. The shifts in volume by patient characteristics showed that the number of inappropriate case patients, according to the insurer's "Standards for approval", decreased more than the number of appropriate case patients after the introduction of insurance coverage for CT. Therefore, the health insurance fee schemes for CT have influenced patient care. 6. The shifts in profits from CT utilization showed a net profit decrease of 31.6%. In order to match the pre-coverage profit level, 5,471 more cases would need to be seen and productivity would need to be increased by 32.7%. This profit decrease resulted from a decrease of CT utilization and low reimbursements. With insurance coverage, net profits from CT were 24.4%, and a margin of safety ratio was 39.6%. Because of the net profits and margin of safety ratio, CT utilization fees for insured appropriate cases could not be considered inappropriate. 7. The shifts in profits from MRI utilization before and after the introduction of CT coverage showed that in order to match pre-CT coverage profit levels, 2,011 more cases would need to be seen and productivity would need to be increased by 9.2%. The reasons for needing to increase the number of cases and productivity result from cost burdens created by adding new MRI units. But with CT coverage already begun, MRI utilization increased. Combined with a minor increase in the MRI fee schedule, MRI utilization showed a net profit increase of 18.5%. Net profits of 62.8% and a 'margin of safety ratio' of 43.1% for MRI utilization showed that the hospital relied on this non-covered procedure for profits. 8. The shifts in profits from CT and MRI utilization showed the net profits from CT decreased by 2.33billion Won while the net profits from MRI increased by 815.7million Won. Overall, these two together showed a net profit decrease of 1.51billion Won. The shifts in utilization showed a functional substitutionary relationship, but the shifts in profits did not show a substitutionary relationship. From these results, We can conclude that if insurance is to be expanded to include previously uncovered procedures using expensive medical equipment, detailed standards should be prepared in advance. The decrease in profits from the shifts in coverage and changes in fees is a difficult burden that should be shared, not carried by the hospital alone. Also, a new or improved fee schedule system should include revised standards between items listed and the appropriateness of the fee schedule should constantly be ensured. This study focused on one university hospital in Seoul and is therefore limited in general applicability. But it is valuable for considering current issues and problems, such as the influence of CT coverage on hospital management. Future studies will hopefully expand the scope of the issues considered here.

We analyzed volume changes in the computerized tomography(CT) and the magnetic resonance imaging(MRI) utilizations. These two volumes are comparative because CT has been covered by the Medical Insurance from the beginning of 1996, however, MRI has not been covered up to now. We investigated 80 hospitals which afforded a facility of CT by the end of 1994. For the comparison of CT utilization, we selected two periods. The first period was from January to June of 1995, in which CT had not been covered by the Medical Insurance and the second period was from January to June of 1966, in which CT had been covered. The information we obtained were characteristics of hospitals, patients numbers per month, monthly uses of CT and MRI, and payments of CT claims, etc. After the Medical Insurance coverage, the number of CT uses per 1,000 patients were increased from January to March, however, was decreased from April to June in 1996 compared to the same periods of 1995. the number of CT uses in clinics were large than those in tertiary hospitals. The number of CT uses in small cities were larger than those in big cities. On the other hand, the number of MRI uses per 1,000 patients did not changed from January to May and was increased from June in 1996 compared to the same periods of 1995. These results showed the substitutional relationship of CT and MRI uses. After the insurance coverage for CT, the utilization of CT was increased because patients payed less than before. However, insurers restricted the payments to the CT claims. This impact might explain the substitutional relationship between CT and MRI.

Background: While there are many studies estimating the effects of private health insurance on various types of health care utilization, few have examined how such effects change in conjunction with important policy reforms in national health insurance (NHI). This study examined how the effect of private health insurance (supplemental and fixed cash benefit) on high-cost outpatient imaging test utilization changed following the expansion of magnetic resonance imaging (MRI) coverage in 2018, which is a key example of the NHI benefit expansion policy in recent years. Methods: Data from the 2017 and 2019 Korea Health Panel Survey, which contained information about healthcare utilization before and after the expansion of MRI coverage in 2018, were used. The incremental effect of private health insurance on high-cost outpatient imaging test utilization for each period were quantified and compared, with special attention given to the type of private health insurance. Results: While people with supplemental private health insurance were more likely to use high-cost outpatient imaging tests than those without, both before and after the expansion of MRI coverage, the incremental effect increased from 1.6% points in 2017 to 2.5% points in 2019. Conclusion: Benefit expansion in NHI does not necessarily reduce disparities in the use of health care between private health insurance subscribers and non-subscribers. The results of our study also suggest that the path through which private health insurance affects healthcare utilization may not be limited to the price mechanism alone but can be more complex.

Background: In 2018, the government increased the fee for the magnetic resonance imaging (MRI) image deciphering services of the external hospital to discourage the redundant MRI scan and to induce appropriate use of the MRI services. It is important to evaluate the effect of the policy to provide the basis for establishing other MRI-related policies. Methods: The healthcare data of the patients who had brain MRI scans were organized by episode and analyzed using the panel study in order to find out the effect of the MRI-related policy on the substitution effect and the medical expenses. Results: As a result of the increase in the fee of deciphering the MRI image, there has been an uplift in deciphering the MRI scan of the external hospital. It implies that more hospitals chose to use the MRI scan taken by other clinics or hospitals, rather than the MRI scan taken at their own facilities. Conclusion: The research results imply that a policy that facilitates the exchange of the medical image data between the hospitals is needed in order to establish an efficient management system of the healthcare resources. Such improvement is expected to reduce the social cost and contribute to the stability in the finance of national health insurance.

본 연구는 MRI 건강보험 급여기준 적용 연혁과 건강보험 청구 자료를 바탕으로 MRI 진료 현황(검사 수, 진료금액)을 분석하여 추후 MRI 급여기준 확대 시 참고할 수 있는 기초자료를 제공하기 위해 시행되었다. MRI 검사가 급여로 적용되기 시작한 것은 2005년으로 초기에는 일부 질환에 대해서만 적응증이 제한되었으나, 2010년, 2013년, 2016년, 2018년 급여 대상이 확대되었으며, 보건복지부는 2021년에는 모든 MRI 검사에 대해 건강보험을 적용키로 하였다. 2010년부터 2017년까지 MRI 검사수와 진료금액 변화는 검사수는 2010년 대비 2017년도에 86.7% 증가하였고, 진료금액은 53.5% 증가하였다. 일반적 특성에 따른 MRI 진료현황은 여성이 남성보다 검사수가 많았고, 연령별로는 70-79세 연령대가 검사수가 가장 많았다. 진료 형태는 외래 검사가 입원검사 보다 많았으며, 의료기관 형태에 따라서는 상급종합병원의 검사수가 가장 많았다. 검사 부위별로는 뇌 MRI 검사수가 가장 높은 비율을 차지하였다. 2013년 12월 심장질환과 크론병에 급여 확대에 따른 진료 현황 변화를 분석한 결과 심장 MRI와 복부 MRI 검사수가 2013년 대비 2014년에 증가하였다. 하지만 전체 대비 검사수가 차지하는 비율이 낮고 질병명과 연계하지 못한 제한점으로 전체 MRI 검사수 증가에 영향을 주었다고 보기는 어려울 것이다. 우리나라는 건강보험 보장성 강화를 위하여 MRI 급여기준을 지속적으로 확대하고 있다. 건강보험 지속가능성과 정책 효과 평가를 위해 추후 지속적인 모니터링이 필요할 것이다.

상대가치란 소모된 자원의 양을 기준으로 의료행위의 가치를 상대적으로 비교한 점수로 의사업무량, 진료비용, 위험도로 구성된다. 2차 상대가치 개정 당시 영상검사 수가는 높은 원가 보존율을 이유로 인하되었다. 영상검사 수가는 상대가치 체계에서 진료비용이 대부분을 차지하고 있으며, 의사업무량은 상대적으로 저평가되어 있다. 문재인케어라고 불리는 새로운 건강보험 보장성 강화 대책은 비급여의 급여화, 본인부담금 상한제 확대, 재난적 의료비 지원을 골자로 국민의 의료비 부담을 줄이는 것이 목표이며 향후 건강보험 재정에 부담이 늘어날 것으로 우려된다. MRI와 초음파 검사 급여 확대는 문재인케어에서 큰 비중을 차지하고 있으며 영상의학과는 문재인케어 적용 과정에서 저평가된 영상검사에서의 의사의 노동을 적절히 평가받을 수 있도록 노력해야 한다.

On account of the dentistry mainly deals with hard tissues such as teeth and bones, CBCT and CT are common imaging modality in clinics. Recently, insurance coverage of MRI has been extended to head and neck region. In addition, unlike CBCT or CT, ionizing radiation is not used, the demand for MRI is gradually increasing in dentistry. Even though, many dentists still think that MRI is a difficult diagnostic tool and they are not confident when to use it. Therefore, the objective of this manuscript is to help the dental clinicians to access easily on MRI by introducing the overview, application and precautions of this imaging tool.
