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...

conclusion according to our findings, ct-guided percutaneous drainage is a safe and effective procedure in the treatment of abdominal abscess and fluid collection. results the average age of the patients was 54 years (range 12 to 79), including 21 (51%) men and 20 (49%) women. the common signs and symptoms were pain (83%) and fever (80.5%). the most prevalent abdominal abscess etiology was prev...

 ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...

Introduction: Unfolding X-ray spectrum is a powerful tool for quality control of X-ray tubes. Generally, the acquisition of the X-ray spectrum in diagnostic radiology departments is complicated and difficult due to high photon flux. Measurement of x ray spectra using radiation detectors could not be performed accurately, because of the pulse pile up. Therefore, indirect methods...

a 50-year-old male underwent a check-up for an insurance company. chest x-ray revealed a large ball-like lesion in the posterior mediastinum. the finding was confirmed by computed tomography (ct) scan (figure 1). the patient was referred to our center, where he had a successful mass removal surgery (figure 2). pathology identified the mass as neurinoma.

in the current study, floating dosage form containing acyclovir was developed to increase its oral bioavailability. effervescent floating tablets containing 200 mg acyclovir were prepared by direct compression method with three different rate controlling polymers including hydroxypropyl methylcellulose k4m, carbapol 934, and polyvinylpyrrolidone. optimized formulation showed good floating prope...
