Abstract

Differentiation between residual head and neck squamous cell carcinoma and post-radiation changes is difficult with routine computed tomography and magnetic resonance imaging. To assess the reliability and reproducibility of mean diffusivity (MD) and fractional anisotropy (FA) parameters of diffusion tensor imaging in differentiation residual head and neck squamous cell carcinoma from post-radiation changes. A retrospective analysis of diffusion tensor imaging of 43 patients with head and neck squamous cell carcinoma cancer after radiotherapy. The MD and FA of the lesion were calculated by the same reader at two-time points. There was a significantly lower difference (P = 0.001) in MD of both readings between residual head and neck squamous cell carcinoma (1.48 ± 0.06 and 1.47 ± 0.07 × 10-3 mm2/s) and post-radiation changes (1.72 ± 0.08 and 1.71 ± 0.11 × 10-3 mm2/s). The FA of residual head and neck squamous cell carcinoma of both readings (0.41 ± 0.09 and 0.42 ± 0.09) shows a significantly higher difference (P = 0.001) than post-radiation changes (0.17 ± 0.04 and 0.16 ± 0.03). There was excellent intra-reader agreement between both readings using MD (K = 0.958) and FA (K = 0.987). The threshold MD and FA used for differentiati...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
