There was also significant difference between ductal carcinoma in situ (or with early infiltration) and invasive ductal carcinoma (P<0.05), and the former was weaker.

MRI is more sensitive than ct in detecting the skull base encroachment. MRI could reveal the early infiltration of the bone marrow and tumor infiltration along the mandibular nerve.

Study Design. Electron and light microscopic changes, neutrophil infiltration, and lipid peroxidation in the spinal cord and early neurologic examination were studied in rats.
