SHOs' interpretation of x rays.

Poor interpretation of chest X-rays by junior doctors.

INTRODUCTION Studies targeting medical students and junior doctors have shown that their radiological skills are insufficient. Despite the widespread use of chest X-ray; however, a study of Danish junior doctors' skills has not previously been performed. MATERIAL AND METHODS A total of 22 participants per-used a standardised series of ten chest X-rays. The test used a multiple-choice form for...

Subject headings: galaxies: general—galaxies: spiral—X-rays: general—X-rays: galaxies—X-rays: ISM

We present results from the analysis of deep ROSAT HRI and PSPC observations of the spiral galaxy M81. The inferred total (0.5–2 keV band) luminosity of M81 is ∼ 3×10 ergs s, excluding the contribution from identified interlopers found within the D25 ellipse. The nucleus of the galaxy alone accounts for about 65% of this luminosity. The rest is due to 26 other X-ray sources (contributing ∼ 10%)...

Medical cost containment: analysis of dual orthopedic/radiology interpretation of X-rays in the trauma patient.

OBJECTIVE The purpose of this study was to investigate the timing, accuracy, clinical impact, and cost of dual orthopedic and radiology interpretation of orthopedic trauma roentgenograms. DESIGN The investigation was performed in a combined retrospective-prospective fashion. MATERIALS AND METHODS Records of 25 retrospective and 25 prospective trauma patients with femoral fractures were revi...
