Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review was performed of the hospital records of 9 children, 6 boys and 3 girls, aged from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (...
Discussion: A large part of both clinical and subclinical lesions found in our daily work are benign and correspond with fibrocystic changes (FCC). This entity is complex and part exhibit traits that define characteristically in MRI and diagnose correctly, but there is another small group of changes that can take the image aspect of cancer. From a complex case, we review the main aspects of the...
The images of dental CBCT imaging systems used in conic shaped beams, stored in the DICOM format, have various applications in the dentistry, including bone density estimation to select the location of the orthodontic implant, bone loss detection and etc. In these systems, unlike CT imaging systems, the resulting images exhibit gray-scale non-uniformity in each of the different axis in FOV. Thi...

Background & Aim: The most common surgically treatable causes of hearing loss are middle ear diseases among which the greatest effect is related to ossicular chain dysfunction. Successful ossicular chain reconstruction certainly improves air conduction thresholds and closes air-bone gap in audiograms, but the effect of this procedure on bone conduction thresholds has remained to be elucidat...
Background: Bone marrow transplantation (BMT) is the treatment of choice for many patients with malignant and nonmalignant diseases. Long-term complications such as osteoporosis should be considered, because it is directly associated with the morbidity and mortality. The purpose of this study is to assess the bone mineral density after allogenic or autologous bone marrow transplantation in pati...
Background: Fluoride (F&minus) is a trace element that is incorporated into bone mineral during bone formation. This study assessed the effect of increasing Fluoride doses on the bone formation and microarchitecture on the Femur of rats by histological, and histometrical methods. Materials and Methods: A total of 16 rats was divided into one group of control and three groups of animals that re...
