Primary MALT lymphoma of the eyelids is a rare disease; chronic infection by Chlamydophila psittaci has been identified as a possible causative agent, but other pathogens may be implicated such Hepatitis C virus and Helicobacter Pylori.
Aim: provide evidence concerning advantages of volumetric modulated arc therapy over intensity modulated radiation therapy.
Agenesis of the corpus callosum (ACC) is a congenital malformation that can occur in isolation or in association with other neurological conditions. However, to our knowledge, no cases of ACC associated with persistent primitive olfactory artery (POA) have been reported.
Background: Simple software extensions to already existing software-infrastructure can monitor treatment results, increase patient safety and enhance patient comfort in a very cost-effective way.
The output of radiotherapy Linear Accelerators (Linacs) is calibrated following national or international protocols like TG-51 by the American Association of Physicists in Medicine [1] or TRS-398 by the International Atomic Energy Agency [2], annually on or before the anniversary date of the commissioning of each Linac. The anniversary dates fall at random times around the year.
Acute appendicitis is the most common cause of acute surgical abdomen during pregnancy. Our study was conducted to review our experience and diagnostic accuracy with MRI during pregnancy and clinical outcomes over a two year period. All pregnant women who underwent an MRI examination of the abdomen between January 2008 and January 2010 at Spectrum Health hospitals were included in the study.
Abdominal-pelvic masses are often described in children and make dread malignancy. In adults or in the elderly, these masses are less documented and are rarely bulky and therefore rarely the cause of abdominal pelvic distension. We report 02 cases of abdominal-pelvic masses encountered in subjects aged 76 and 91 years explored on the computed tomography (CT) with the aim to emphasize the contribution of CT in the diagnosis of large abdominal-pelvic masses in the elderly in sub Saharan Africa.
Objective: Heterotopic ossification (HO) is a biological process characterized by de novo bone formation in tissues which should not undergo ossification in normal condition. Frequently, it is a complication that occurs after head injuries, spinal cord injuries, cerebrovascular events, burns, fractures, dislocations and joint replacements.
Percutaneous spine biopsy has widely replaced open biopsy during the last 50 years. Closed biopsy is more cost effective, less invasive, and has fewer complications than open procedures. A literature search was conducted in PubMed for percutaneous spine biopsy. The contributing factors to the success of the biopsy were identified by reviewing the articles and their references. These factors included location and type of lesion, needle system and use of different modalities of imaging as well as the physician's expertise.
The purpose of this study is to determine the incidence and significance of incidental findings on pediatric oncologic PET/CT. A retrospective analysis of all PET/CT scans obtained at Helen DeVos Children's Hospital between 2004-2008 in pediatric oncology patients was performed.
Various techniques are used in image-guided radiotherapy (IGRT). Cone beam computed tomography (CBCT) is widely used in IGRT on linear accelerators. The increased accuracy of IGRT enables reducing planning target volume margins and doses to normal tissues.
Exact reproduction of patient position is crucial in radiotherapy. We evaluated the reproducibility of a CT based treatment simulation with the PICTOR 3D® system (LAP, Luneburg, Germany) and examined its influence on workflow in daily routine.

Women have fixed ovarian follicles after birth and the number of the follicles declines with age. The decrease can be regulated by genetic, hormonal and/or therapy procedures. Radiation exposure can lead to premature ovarian failure (POF). POF is defined as interruption of the ovarian function in an adolescent woman. Genetic disorders including translocations and damage on the ovarian tissue may result POF. The essential diagnostic criteria is an adolescent woman younger than 40 years of age. The diagnosis depends on at least 4 months of amenorrhea and increased FSH levels (=40 mIU/ml) in 2 blood samples at an interval of 1 month.
Today the radiologic investigations are the indispensable diagnostic tools in medical care especially in emergency, oncology and pediatry departments. The imaging has the benefits for the patients follow-up as well as the diagnostic significance. In the last fifteen years the advanced imaging techniques in neuroradiology provides very important data of the brain such as metabolites with MR Spectroscopy, microvascularity with perfusion imaging, integrity of white matter with diffusion tensor imaging and network of cortex with functional imaging.
