A 13-year-old neutered female Maltese was referred to Veterinary Medical Teaching Hospital of Seoul National University with 8-month-history of gradually enlarging retrobulbar mass in the right eye. On the ophthalmic examinations, exophthalmos, exposure keratitis, and cataract were observed, and menace response was absent in the eye. The fellow eye was normal except for nuclear sclerosis. On the ocular ultrasonographic evaluation, a mass was identified in retrobulbar and periocular region in the right eye. Exenteration was performed in order to remove the mass. Histopathologic evaluation revealed that most part of the mass was composed of epithelial-like neoplastic cells. Invasion into adipose cells and osseous metaplasia around the mass were also confirmed. Based on the radiologic and histopathologic examination, the mass in the right eye was diagnosed as primary retrobulbar meningioma. Eleven months after the surgery, recurrence was not observed.

Background: To evaluate the clinical and functional outcomes of arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension, and investigate the radiologic and clinical benefits from the results. Methods: We evaluated patients treated with arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension from November 2008 to September 2015. Fractures with displacement exceeding one-fourth of the anterior-articular surface or more than one-third of the posterior-articular surface in radiographic images were treated by surgery. Clinical assessment was conducted based on range of motion, Rowe score, and Constant score of injured arm and uninjured arm at last follow-up. Results: Fifteen patients with Ideberg classification grade III, IV, and V glenoid fracture who underwent arthroscopic-assisted reduction using percutaneous screw fixation were retrospectively enrolled. There were no differences in clinical outcomes at final follow-up compared to uninjured arm. Bone union was seen in all cases within five months, and the average time to bone union was 15.2 weeks. Ankylosis in one case was observed as a postoperative complication, but the symptoms improved in response to physical therapy for six months. There was no failure of fixation and neurovascular complication. Conclusions: We identified acceptable results upon radiological and clinical assessment for the arthroscopic-assisted reduction and percutaneous fixation. For this reason, we believe the method is favorable for the treatment of Ideberg type III, IV, and V glenoid fractures. Restoration of the articular surface is considered to be more important than reduction of fractures reduction of the scapula body.

Objective: To show a decrease in tumor recurrence and improvement in quality of life in patients with recurrent cervical cancer. Method: A 58-year-old female patient diagnosed with recurrent cervical cancer in February 2021 was treated for 14 months with integrative cancer treatment (ICT) to decrease the tumor size and improve chemotherapy-induced peripheral neuropathy (CIPN) and nausea. The patient underwent chemotherapy or concomitant chemoradiation therapy (CCRT) with ICT. Radiologic outcomes were assessed by abdomen & pelvis computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT) based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed by the National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the 14 months of treatment, the size and metabolic activity of the recurrent tumor decreased and underwent partial remission based on RECIST. The NRS scores for CIPN and nausea were improved, and the ECOG score improved from grade 2 to 1. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a synergetic effect with chemotherapy or radiotherapy for recurrent cervical cancer.

Purpose: A response to conservative treatment is usually obtained in cases of ischiogluteal bursitis. However, the time required to achieve relief of symptoms can vary from days to weeks, and there is a high recurrence rate, thus invasive treatment in addition to conservative treatment can occasionally be effective. Therefore, the aim of this study was to examine surgical excision in cases of refractory ischiogluteal bursitis and to evaluate patients' progression and outcome. Materials and Methods: A review of 21 patients who underwent surgical excision for treatment of ischiogluteal bursitis between February 2009 and July 2020 was conducted. Of these patients, seven patients were male, and 14 patients were female. Injection of steroid and local anesthetic into the ischial bursa was administered at outpatient clinics in all patients, who and they were refractory to conservative treatment, including aspiration and prescription drugs. Therefore, surgery was considered necessary. Excisions were performed by two orthopedic specialists using a direct vertical incision on the ischial area. A review of each patient was performed after excision, and quantification of the outcomes recorded using clinical scoring systems was performed. Results: The results of radiologic evaluation showed that the mean lesion size was 6.2 cm×4.5 cm×3.6 cm. The average disease course after excision was 21.6 days (range, 15-48 days). Measurement of clinical scores, including the visual analog scale and Harris hip scores, was performed during periodic visits, with scores of 0.7 (range, 0-2) and 98.1 (range, 96-100) at one postoperative month, respectively. Conclusion: Surgical excision, with an expectation of favorable results, could be considered for treatment of ischiogluteal bursitis that is refractory to therapeutic injections, aspirations, and medical prescriptions, particularly in moderate-to-severe cases.

목적: 판독용 모니터의 성능을 평가하는데 있어 불필요한 시간 및 인력 등을 줄이고 판독의 최적화 유지와 모니터의 upgrade 시기, 그리고 교체 시기를 결정할 수 있는 시스템을 구축하는데 필요한 적절한 수준의, 일정기간의 성능평가 관리 주기 및 calibration 주기를 결정하고자 하였다. 대상 및 방법: 판독용 LCD 컬러 모니터(CCL350i, Totoku, Japan) 20대를 대상으로 2007년 3월부터 8월(첫 calibration 후 3, 4, 5, 6, 7, 8개월째)까지 매달 1회에 걸쳐 한 달 주기로 총 6회의 성능 평가를 하였다. 성능 평가에 사용된 측정 도구는 휘도계(DTP 94 39630, X-Rite Inc. U.S.A.)와 조도계(LX-101 Q031871, Lutron, U.S.A.) 그리고 모니터 성능관리 프로그램인 AAPM TG 18 protocol를 이용하였다. 성능평가 항목은 기하학적 왜곡(geometric distortion), 반사 테스트(reflection test), 휘도 반응 평가(luminance response evaluation), 휘도 균일도(luminance uniformity), 분해능(resolution), 노이즈(noise), 베이링 그레어(veiling glare), 색도(chromaticity) 등 8개 항목을 포함하였다. 결과: 기하학적 왜곡 평가와 반사 테스트, 휘도 균일도 테스트, 분해능, 노이즈 평가, 베이링 그레어 테스트, 색도 테스트 등은 AAPM TG 18에서 권고하는 기준치에 모두 부합되었다. 휘도반응평가 중 예측되는 최대 휘도와 관측되는 휘도의 편차 항목에서 4개월째부터 25%(4대)의 모니터가 8개월째까지 기준 편차를 벗어나기 시작하였으며, 8개월째에는 다른 모니터 7대에서도 편차를 보이기 시작하여 전체적으로 55%(11대)의 모니터에서 기준 편차를 벗어나고 있었다. 또한 대조도 반응의 편차 항목에서 4개월째부터 예측되는 최대 휘도와 관측되는 휘도의 편차의 기준치를 벗어나기 시작한 4대의 모니터 중 5%(1대)에서 4개월째부터 8개월째까지, 또다른 2대는 8개월째부터 편차를 보여 전체적으로 8개월째에는 15%(3대)의 모니터에서 기준 편차를 벗어났다. 결론: 성능평가의 주기는 calibration 후 4개월째부터 오차 범위를 벗어나는 결과와 모니터 수 그리고 성능 검사에 소요되는 인력 및 시간을 고려할 때 3개월에 한번씩 평가함이 효율적이라고 판단된다. 또한 calibration 주기는 8개월째부터 50% 이상에서 편차를 보인 결과 및 성능평가 주기를 고려할 때 calibration 후 6개월을 주기로 calibration을 다시 시행하여야 할 것으로 판단된다.

The purpose of this study was to discuss the required items and feasibility of medical records of radiological examinations performed by radiological technologists at medical institutions. An online survey was conducted to a total of 10,000 radiation-related workers, of which 1,026 (10.3%) responded. As a research method, self-made questionnaires were used. The online survey was conducted from September 10 to September 20, 2021 for the survey period. For response data, a Chi-square test was performed according to demographic characteristics using SPSS 27.0 version (IBM Inc., Chicago, Ill, USA), and it was judged to be significant when the P value was less than 0.05. The reliability of the questionnaire response was found to be Chronbach α=0.933. More than 90% of the medical records related to radiological examinations are necessary, and they answered that a curriculum, remuneration curriculum, and legal system for medical records should be prepared. More than 90% of the respondents agreed with the proposal of the Radiological Technologist Independent Act for legal preparation, and most of the information required for medical records is currently recorded in DICOM images. According to the demographic characteristics, the medical record requirement for radiological examination, curriculum, continuing education, and legislation were found to be higher with higher education and higher with longer working experience. In addition, most of the radiology departments showed a high demand for medical records, so most of them responded positively to the medical records requirements for radiological examinations. This study analyzed the medical record requirements for radiological examinations, and as shown in the results, medical record requirements for radiological examinations was found that most radiological technologists felt need for the new law and supported it. In addition, if the information recorded in the DICOM image is used, it is considered that medical records could be easily prepared without additional work by the radiological technologists.

The purpose of this study is to check the extent to which "instruction of physician or dentist" defined in the Medical Service Technologists, etc. Act is applied in relation to radiography examination procedures for radiological technologists. In addition, it is intended to present basic data on the requirement to revise the Medical Service Technologists, etc. Act in the radiological technologist's duty area and scope of work, The subjects of this study were radiological technologists with license, and the response data were collected after sending the questionnaire link written on the online questionnaire form. The final number of respondents were 1,018, and the response rate was 6.8%. Most of the negative responses were "I have never received 'instruction' for radiologic examination by a physician or dentist, including a radiologist in a medical environment." There were a high perception that "the professionalism in radiation examination on radiological technologists are higher than that of a physician or dentist." They answered that the current continuing education has a great impact on maintaining and continuing professionalism and learning new knowledge in the radiology field. In addition, the radiological technologists provide a very high level of education in areas related to radiography procedure ethics such as patient care, patient safety, and patient privacy protection, as well as specialized fields such as radiation-related examination methods, radiography examination dose, and patient exposure dose. Radiological technologists replied that they were receiving it consistently. In conclusion, in the current medical environment, the 'instruction' of a physician or dentist cannot be seen as being realistically performed. The phrase 'instruction' of a physician or dentist as defined in the Medical Service Technologists, etc. Act is considered inappropriate in respect of the fact that the state recognizes the qualifications of the medical service technologist through a license. It is thought that revision to a new term suitable for the current medical environment is necessary.
