There was a statistically significant difference between the apparent diffusion coefficient values (ADC) of malignant and benign lesions (0.69\u2009\u00b1\u20090.22\u2009\u00d7\u200910\n                      <jats:sup>\u22123<\/jats:sup>\n                      \u2009mm\n                      <jats:sup>2<\/jats:sup>\n                      \/s and 1.39\u2009\u00b1\u20090.52\u2009\u00d7\u200910\n                      <jats:sup>\u22123<\/jats:sup>\n                      \u2009mm\n                      <jats:sup>2<\/jats:sup>\n                      \/s respectively). The optimal cut-off ADC value was 1.08 with 75% specificity and 97% sensitivity. The routine contrast-enhanced MRI had predicted benign and malignant tumors with 65% sensitivity and 44% specificity. The sensitivity and specificity were greatly increased when quantitative diffusion-weighted MRI was combined with routine contrast-enhanced MRI: 100%, and 88% respectively. A receiver operating curve was generated. The area under curve was 0.88 ( p\u2009&lt;\u20090.001, 95% CI: 0.76\u20130.99).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
