Fig. 9. —Scatterplot shows longest diameter of tumor (•) measured at clinical examination and at pathology after chemotherapy (n = 51). Note five cases for which results at pathology were questionable (). Correlation between measurements was moderate with and without these cases (r = 0.6 and r = 0.55, respectively; p < 0.001 for both). Clinical assessment of lesion size by palpation produced notably less accurate lesion characterization than MR imaging. Trend line (black line) depicts least-squares fit for data.
