The MVD of corresponding tumor specimens, obtained from Computed Tomography-guided biopsies, were counted with CD34 staining.<h4>Statistical tests</h4>Pearson correlation analysis; one-way analysis of variance analysis; least significant difference-t method of multiple comparisons.<h4>Results</h4>The correlation coefficient was 0.983 and 0.972 for the measurement and remeasurement of K<sup>trans</sup> and V<sub>e</sub> . The gene discussed is CD34; the disease is neoplasm.
