Star volume analysis estimates each marrow cavity space as a sphere, and thus the Vm space is based on the formulas used to calculate spherical volumes.
Osteochondromas are best illustrated with MRI, mainly the extension of the native medullary cavity into the tumor's marrow cavity. The cartilaginous cap is richer in water than the bone part, and the cartilage thickness can be easily measured: a thickness higher than 1.5 to 2 cm in adults and 3 cm in children is suspect for a malignant transformation into a low-grade osteosarcoma [15].
An NMR 1D profiling in the longitudinal direction was acquired along the radial axis of the bone, for definition of the scanning zones (either the center or periphery of the marrow cavity).
Conversely, the viability of cancellous bone within bone marrow cavity was determined by the presence of osteocyte nuclei within lacunae.
Sclerosis of the bone causes narrowing of the marrow cavity and bone marrow failure with consequent life-threatening pancytopenia and hepatosplenomegaly due to extramedullary hematopoiesis (2, 4).
During first three days of the experiment the inflammatory process in the bone was visualized as the groupings of gray and yellow exudates within bone marrow cavity, sometimes in subperiosteal space and sometimes in soft tissues of the limb.
Geometrical measurements (bone length, bone thickness, marrow cavity diameter, cortex layer thickness) were performed in the midst of the bone (Fig.
The second technique, apheresis, extracts PBSCs from the blood through a machine after a drug mobilizes the stems cells to leave the marrow cavity and enter the blood stream.
As the mixed phase progresses and the marrow cavity is replaced with medullary bone, signal intensity will begin to diminish.
The composition of cells in the bone marrow cavity has an important influence on the productivity of blood stem cells.
Extramedullary hematopoiesis (EM H) is the production of hematopoietic precursors outside the bone marrow cavity, and it causes mass effects according to its localization.
