Sonographic measurements often give considerable diagnostic significance. However, large discrepancy betweenthe real anatomic sizes and sonographic measurements could cause an incorrect diagnosis. Authors carried out aseries of experiment using a phantom and two scanners and the results are as follows: 1. There is a littledifference in errors between two scanners, and the mesurement does not almost always correspond to the realdistance. 2. The rates of errors of the measurements are almost fixed regardless of the positions of thereflcetors. 3. There is no relationship between the transducer MHZ and error rate. 4. As the error is derived from the scanner electronics it is necessary to calibrate the scanner periodically, and if not calibrated one shouldconsider the error rate of the scanner in the anatomical measurement.

Twenty-eight cases of fracture of the femur and tibia on the same leg were treated in Pusan Maryknoll Hospital during the period from April 1981 to Jun 1988. We studied all of these patients, divided by five groups according to the method of treatment, with analysis of treatment and end results. The following results were obtained. 1. The incidence of trauma was high in the young man, and most frequent in the third decade (42.9%). 2. The main cause of injuries was traffic accident; 22 patients (78.6%). 3. The common fracture site was middle one-third in femur and tibia respectively. 4. The most common associsted injury was head trauma (9 case). 5. The average healing time of fracture was 20.7 weeks in femur and 22.7 weeks in tibia of group 3, 4, 5. 6. The best results were obtained in cases both fractures stabilized surgically.

BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.

A study was done to evaluate the diagnostic value of ultrasonography on acute scrotum patients. During the last three years, 25 patients were managed at Cheju Medical Center, eight of them were testicular torsion patients including one cryptorchid testicular torsion. one torsion of appendix testis, 11 acute epididymitis and 5 testicular rupture due to blunt scrotal trauma. Ultrasonography revealed enlarged testis and epididymis in all of the 8 testicular torsion patients and 7 of them showed inhomogeneously decreased echogenecity of the testis and epididymis. All acute epididymitis patients showed enlargement of the epididymis, and inhomogeneously decreased echogenecity was found in 8 of them. But testicular echogenecity was normal in all of the acute epididymitis patients and enlargement of the testis was found in two. All of the 5 testicular rupture patients showed irregular hypoechoic portions in the testicle and distorted testicular morphology, and linear fracture lines of the testis were found in two. We could suggest that scrotal ultrasonography is useful for the early differential diagnosis of the acute scrotum, especially when scrotal radioisotope scan is not available.

PURPOSE: Knee IVIR images were repeatedly obtained after intravenous administration of gadopentetate dimeglumine to evaluate the arthrographic effect and to determine the optimal scan timing and technique. MATERIALS AND METHODS: Sagittal Tl-weighted (650/15) sequences were repeated before and after intravenous gadolinium enhancement in 26 patients who were divided into exercise (14/26) and nonexercise (12/26) groups. Fourteen patients in exercise group were allowed to move the affected knee joint actively for 10 minutes immediately after the first post-enhancement scan and before repeating scans. The signal intensities in central and peripheral portions of the joint were measured and compared between these two groups. RESULTS: In all cases, enhancement of joint fluid began at peripheral portion and progressed toward central portion. The diffusion rate in exercise group was far faster than that in nonexercise group and homogeneous arthrographic image was revealed within 10 minutes after completion of joint movement. The arthrographic effect continued and the rate of signal decrease was quite slow. CONCLUSION: MR arthrographic image of knee joint can be obtained within 10 minutes after completion of a few minute exercise following intravenous injection of gadopentetate dimeglumine. Intravenous MR arthrography is expected to become an useful method as a convenient alternative to direct MR arthrography.
