a 16-day-old female was referred with congenital swelling on her right shoulder. on examination, there was a hard, round, ecchymotic, nontender, slightly movable, warm and shiny 10x15 cm mass on the right axillary pits which was extended to the right side of neck and chest wall. the mass separated the shoulder from the chest wall causing paralysis of right hand. chest x-ray, ultrasound and mri ...

Gas in the leg is not always a gas gangrene. Abdominal infection with gas forming organisms may spread to the thigh & leg. We report a case of critically ill patient who presented to the emergency department with features suggestive of septic arthritis of the left hip. Assessment and further intervention revealed subcutaneous emphysema of the leg secondary to an infection of a previously asympt...

We present a systematic fit of a model of resonant cyclotron scattering (RCS) to the X and soft γ-ray data of four magnetars, including anomalous X-ray pulsars, and soft gamma repeaters. In this scenario, non-thermal magnetar spectra in the soft X-rays result from resonant cyclotron scattering of the thermal surface emission by hot magnetospheric plasma. We find that this model can successfully...

X-ray phase-contrast tomography can significantly increase the contrast-resolution of conventional attenuation-contrast imaging, especially for soft-tissue structures that have very similar attenuation. Just as in attenuation-based tomography, phase contrast tomography requires a linear dependence of aggregate beam direction on the incremental direction alteration caused by individual voxels al...

Intussusception is the most common cause of intestinal obstraction in children aged 3 months to 6 years. Complete understanding of its clinical and radiographic manifestations can play a major role in the early diagnosis and treatment and prevents its complications. In this study plain abdominal X-rays of 51 patients with intussusception were evaluated. Suggestive radiographic signs of the dise...
