1 Diffusion-Weighted Magnetic Resonance Imaging for Diagnosing Malignant Pulmonary Nodules/Masses: Comparison with Positron Emission Tomography  Takeshi Mori, MD, PhD, Hiroaki Nomori, MD, PhD, Koei Ikeda, MD, PhD, Koichi Kawanaka, MD, Shinya Shiraishi, MD, PhD, Kazuhiro Katahira, MD, PhD, Yasuyuki Yamashita, MD, PhD  Journal of Thoracic Oncology  Volume 3, Issue 4, Pages (April 2008) DOI: /JTO.0b013e318168d9ed Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 CT image (A), positron emission tomography image (B), and diffusion-weighted image (C) of lung cancer patient. Journal of Thoracic Oncology 2008 3, DOI: ( /JTO.0b013e318168d9ed) Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions

3 FIGURE 2 The receiver operating characteristics curve of ADC-min value for diagnosing malignancy for pulmonary nodules/masses showing the optimal cutoff value to be 1.1 × 10−3 mm2/s. Area under curve: (95% confidence interval: 0.846–0.968).

5 FIGURE 4 Correlation plots between ADC-min and SUV-CR. Open circle shows malignant and closed circle shows benign nodule/mass. Dotted lines show cutoff value for ADC-min and SUV-CR. The solid line shows the linear regression line and the broken lines show 95% confidence interval. ADC-min = minimum apparent diffusion coefficient; SUV-CR = contrast ratio of standard uptake value.
