OBJECTIVE To investigate radiation doses in pediatric chest radiography in a national survey and to analyze the factors that affect radiation doses. MATERIALS AND METHODS The study was based on the results of 149 chest radiography machines in 135 hospitals nationwide. For each machine, a chest radiograph was obtained by using a phantom representing a 5-year-old child (ATOM® dosimetry phantom,...

BACKGROUND To compare the test performance of plain radiography and computed tomography (CT) in the detection of patients with cervical spine injuries following blunt traumatic events among those patients determined to require screening radiography. METHODS We conducted a MEDLINE search for articles published from January 1995 through June 2004, manually reviewed bibliographies, and hand sear...

BACKGROUND General practitioners often diverge from clinical guidelines regarding spine radiography. This study aimed to identify and describe A) factors general practitioners consider may affect their decisions about ordering plain radiography for back pain and B) barriers to guideline adherence suggested by such factors. METHODS Focus group interviews regarding factors affecting ordering de...

OBJECTIVE The purpose of this study was to determine the usefulness of contrast-enhanced radiography of the Hartmann's pouch for evaluating postoperative abnormalities. MATERIALS AND METHODS We performed a retrospective study of 84 patients with a Hartmann's pouch who underwent contrast-enhanced radiography of the pouch during a recent 7-year period. Sixty-four patients underwent single-contr...

OBJECTIVE The purpose of our study was to assess MDCT findings and the advantages of MDCT compared with radiography in patients referred to a level 1 trauma center for diagnostic evaluation of acute ankle and foot trauma. MATERIALS AND METHODS During a period of 37 months, 388 patients underwent MDCT of the ankle and foot due to an acute trauma. Imaging studies (MDCT and radiography) were ret...

INTRODUCTION Ultrasonography is being increasingly utilized in acute care settings with expanding applications. Pneumothorax evaluation by ultrasonography is a fast, safe, easy and inexpensive alternative to chest radiographs. In this review, we provide a comprehensive analysis of the current literature comparing ultrasonography and chest radiography for the diagnosis of pneumothorax. METHODS...
