Objectives : The aim of this study was to evaluate the usefulness of ultrasonography of knee osteoarthritis. Methods : 124 osteoarthritis patients classified by the American College of Rheumatology (ACR) clinical criteria were included in the study. Simple X-ray and ultrasonography examination (effusion, osteophyte, articular cartilage, Backer's cyst) of knee in pain were performed. Also VAS, KWOMAC score were checked. Results : X-ray showed abnormal findings in 112 patients, but ultrasonography showed abnormal findings in all 124 patients. 12 Patients with unremarkable knee X-ray showed effusion and osteophyte in the ultrasonography. Effusion was discovered only in 18 cases of X-ray and 62 cases of ultrasonography. Group with effusion showed higher VAS mean figure but couldn't retrieve significant difference. KWOMAC showed no significant difference. Conclusions : Osteoarthritis patients with no abnormality in X-ray diagnosed abnormal findings through sonograph, which manifest that sonograph can be utilized for differential diagnosis especially sensitive on the problem of effusion.

Objectives : To compare the differences between the symptoms and the findings of MRI(magnetic resonance imaging) and x-ray, we studied the patients with neck pain or radiating pain, which has been diagnosed as cervical herniated disc recently. Methods : We randomly selected among the 143 patients with x-ray and cervical spine(C-spine) MRI films who have visited Ja-seng hospital with neck pain and neck and radiating pain from April 1 of 2010 to May 1. We used SPSS 13.0 for windows in analyzing statistical data of study results and the level of significance was below 0.05. Results : 1. There were no significant differences between the presence of radiating pain and the amount of cervical herniation(p>0.05). 2. If the finding of a x-ray showed narrowing, based on MRI findings, the amount of herniation was more severe(p>0.05). 3. There were no significant differences between the presence of radiating pain and the findings of x-ray(p>0.05). 4. Among the 143 cases, which showed findings beside HIVD(herniation of intervertebral disc) were 13 cases. 88 cases of straightening(61.5%). 78 cases of uncovertebral joint arthrosis(54.5%). 25 cases of stenosis(17.5%), 13 cases of retrolisthesis(9.1%), 8 cases of osteophyte(6.6%), 4 cases of spondylolisthesis(2.8%), 2 cases of hemangioma(1.4%), 3 cases of OPLL(ossification of posterior longitudinal ligament)(2.1%), 2 cases of block vertebrae(1.4%), 2 cases of spondylitis(1.4%), 1 case of kyphosis(0.1) and 1 case of ligamentum flavum hypertrophy(0.1%). Conclusions : The findings from this study suggest that there was no relation between radiating pain and radiological result. On the other hand, diagnosis of x-ray and MRI showed significant relevance. The narrower disc space there were, the severer the state of herniation there existed.

The patient with findings of diffuse infiltrative lung on chest X-ray has various causes; therefore, the prognosis is different and the treatment should be changed according to the cause. We are trying to identify the meaning of operative lung biopsy and to 11nd a more accurate and effective procedure. We reviewed 46 medical records of patients with the findings of diffuse infiltrative lung on chest X-ray who had undergone operative lung biopsy or biopsies for 8 years. The open lung biopsy were done in 22 cases(47.8%) and thoracoscopic lung biopsy in 24 cases(52.2%). There is no significant difference in the rate of diagnosis(p=0.452) and the incidence of complications(p=0.155) between these groups. The number of cases with more than two biopsies are 9(19.6%) and that of one biopsy are 37(80.4%). There are no statistical difference in the rate of diagnosis(p=0.928) and the incidence of complications(p=0.125). The postoperative complications occurred in 8 cases,7 cases of air leak more than 7 days and 1 case of respiratory insufficiency. In the diagnosis and treatment of the patients with findings of infiltrative lung on chest X-ray, the operative lung biopsy is the very necessary course, and shows satisfactory rate of diagnosis with negligible complications.

Objective: This study was designed to analyze the utility of routine chest X-ray on Korean medicine hospital admission. Methods: The chest X-ray reports and medical records of 618 patients who were admitted to Daejeon Korean Medicine Hospital from May 1, 2021 to June 30, 2021 were retrospectively reviewed. Results: Of the 618 patients newly hospitalized from May 1, 2021 to June 30, 2021, 560 patients (excluding readmission) were analyzed. The mean age of 560 patients was 53.26±17.20 years. There were 52 patients with abnormal findings, and their mean age was 69.62±15.59 years. Many of these patients had chest symptoms and a history of chest disease. There was no case that showed a significant diagnostic result by chest X-ray examination. Conclusion: The diagnostic usefulness of routine chest X-rays in Korean medicine hospital admission is low. But this does not mean that there is no need to perform routine chest X-rays upon admission.

Objective : Women can be affected physically and psychologically by pregnancy and delivery. Because the relaxation of pelvic ligaments has a chance to cause pelvic deviation, we investigated the radiological peivic deviation according to delivery types and experiences. Method : 71 patients were evaluated by X-ray findings. Every patients divided into two group according to delivery types and experiences. After measured innominate measurement. off centering measurement, sacral ala measurement and ilium shadow measurement, X-ray findings in each group were analyzed statistically. Results and Conclusions : It was concluded that the ilium was more deviated into outer side in normal delivery group than caesarean operation group, and more deviated into inner or outer side in multipara group than primipara group.

The study aims to develop a novel, lead-free, flexible and lightweight composite shielding material against ionizing radiation. For this, it was used bismuth oxide (Bi₂O₃) in RTV-2 silicon matrix. The shielding tests were carried out in both diagnostic X-ray energies and intermediate gamma-ray energy range of up to 662 keV to determine the radiation attenuation properties of this material in terms of attenuation ratio, half value layer, tenth value layer, mean free path and lead equivalency of samples in weight of 30%, 40%, 50% in Bi₂O₃. In the diagnostic X-ray energy range, half value layer, tenth value layer and lead equivalency (in mm Pb) of the produced samples were measured at 80 and 100 kVp narrow beam conditions according to the requirements of EN IEC 61331-1 standard. The results show that lead equivalent values of the produced novel sheets was measured to be 0.16 mm Pb, corresponding to a 6 mm thickness of the flexible sample when it contains 30% wt. Bi₂O₃ in RTV matrix. The experimental findings for durability and flexibility also indicated that this new RTV-based flexible, lead -free shielding composite can be used safely for especially for manufacturing aprons, garments and thyroid guards used in mammography, radiology, nuclear medicine and dental applications in practice.

The purpose of this study was examine the general characteristics of relapsed pulmonary tuberculous patients (i.e. age, sex, weight, occupation, previous forms of treatment, drug sensitivity, and the frequency of relapse) in order to improve future treatments of tuberculosis as well as to perpetuate health education. The data was obtained from the medical records of 186 relapsed pulmonary tuberculosis patients who were registered for treatment at various public health offices in Seoul during the year of 1994. The major findings obtained from the study were as follows; 1) The male to female ratio of relapsed pulmonary tuberculous patients was about 7:3, more specifically 23.7% of the men and 30.9% of the women were between 20 and 29 years of age. 2) Comparing initial less aggravated states to relapsed states, patients with minimal X-ray findings later proved moderately advanced X-ray findings. Furthermore, patients with negative sputum AFB findings later proved positive sputum AFB findings. 3) Of the 186 patients studied, 91.9% suffered, relapse and 8.1% suffered 2 or more relapses. Of the patients who suffered at least 1 relapse, 54.8% received short-term treatment, 26.9% received long-term treatment, and 18.3% received treatment of an unknown during their initial tuberculosis treatment periods. 4) fifty five point four percent of the patients had no reaction to the drug treatment(not available), 25.9% of the patients had sensitive reaction to the drug treatment, 18.7% of the patients had resistant reaction to the- drug treatment. Drug resistance was higher in patients that exhibited positive X-ray findings as well as in patients that exhibited positive sputum AFB findings. furthermore, patients receiving treatment of an unknown nature(35.5%) exhibited higher drug resistance than those receiving short-term treatment(13.6%) and long-term treatment(17.0%). 5) Of the 160 patients who suffered relapses, 8.8% suffered a relapse within 1 year after treatment and 91.2% suffered a relapse at least 1 year after treatment. Furthermore, our study showed that women, under 30, who received short-term treatment and encounterd complications during their primary treatment suffered relapses faster than any other groups studied. In addition, minimal X-ray findings and sputum AFB findings were not correlated to the time relapse occured. Therefore, the seater efforts are needed to prevent relapsed pulmonary tuberculosis.

This is a case report of a 69 years old non-smoking male patient with a lung cancer who presented with postherpetic neuralgia on the left T2, 3 and 4 dermatomes. This pain was aggravated in supine position. The patient did not have any other symtoms or signs to suggest the possibility of a lung cancer. Patient's baseline laboratory findings were essentially normal. Routine chest X-ray revealed hazy densities in the left apex. Further evaluation with chest CT confirmed the presence of a lung cancer corresponding to the densities seen on the chest X-ray.
