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...
