conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

in order to study the normal hematopoiesis, cellular components and myeloid/erythroid (m/e) ratio in the bone marrow of the pheasant (phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. the bone marrow smears were stained using the giemsa stain. the results indicated that the development and formation of blood cell...

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

Bone graft materials are widely used in reconstructive orthopedic procedures to promote new bone formation and bone healing, provide a substrate and scaffolding for development of bone structure, and function as a means for direct antibiotic delivery. Bone graft materials include autografts, allografts, and synthetic substitutes. An autograft (from the patient's own bone) supplies both bone vol...

OBJECTIVE Recent studies suggest a close local link between bone marrow adiposity and endosteal bone formation. Using magnetic resonance imaging, we examined whether the relation between the amount of marrow fat and cortical bone is present at multiple sites along the diaphyses of the long bones of young and old males and females. DESIGN The relations between values for cortical bone area and...

OBJECTIVE We tested the hypothesis that direct intramyocardial injection of bone marrow mononuclear cells in patients with non-ischemic dilated cardiomyopathy can improve left ventricular function and physical capacity. METHODS Thirty non-ischemic dilated cardiomyopathy patients with left ventricular ejection fraction <35% were randomized at a 1:2 ratio into two groups, control and treated. T...

background and objectives: bone marrow necrosis (bmn) is a rare and ominous complication of wide variety of diseases including hematologic malignancy. this study was performed to identify frequency and the underlying associated diseases of marrow necrosis. materials and methods: in this descriptive study, totally 850 bone marrow trephine biopsies related to living patients at the pathology depa...

OBJECTIVE To evaluate by magnetic resonance imaging changes in bone marrow of patients undergoing treatment for type I Gaucher's disease. MATERIALS AND METHODS Descriptive, cross-sectional study of Gaucher's disease patients submitted to 3 T magnetic resonance imaging of femurs and lumbar spine. The images were blindly reviewed and the findings were classified according to the semiquantitativ...

Bone marrow infarction was investigated by 99mTc-sulfur colloid imaging in 42 patients with sickle cell anemia (SS) over a period of 2 yr. Marrow defects were demonstrated in 28 patients (66.6%), and in 15 (aged 19--52 yr), they were matched by roentgenographic evidence of medullary bone infarction. Repeated images showed no change in the size or site of these defects. Among 13 patients (aged 6...
