1 Date of download: 9/19/2016 Copyright © 2016 SPIE. All rights reserved. (a) Photo of breast coil and (b) photo of patient positioning for MR exam. Figure Legend: From: Combined diffuse optical spectroscopy and contrast-enhanced magnetic resonance imaging for monitoring breast cancer neoadjuvant chemotherapy: a case study J. Biomed. Opt. 2005;10(5):051503-051503-9. doi:10.1117/1.2070147

(a) Photo of laser breast scanner and (b) photo and (c) diagram of the handheld probe containing an avalanche photodiode (APD), FDPM fiber bundle, and SS source and detector fibers. Figure Legend: From: Combined diffuse optical spectroscopy and contrast-enhanced magnetic resonance imaging for monitoring breast cancer neoadjuvant chemotherapy: a case study J. Biomed. Opt. 2005;10(5):051503-051503-9. doi:10.1117/1.2070147

Eleven DOS measurements were taken at 1.0-cm intervals across the lesion and surrounding normal tissue from superior to inferior in the right upper outer quadrant. Six DOS measurements were taken at 2.0-cm intervals on the identical location on the left upper outer quadrant.

Opt. 2005;10(5):051503-051503-9. doi:10.1117/1.2070147

4 Date of download: 9/19/2016 Copyright © 2016 SPIE. All rights reserved. Fat-suppressed MR images of a 5.4-year-old postmenopausal woman with a 3.7×3.9×3.9cm invasive ductal carcinoma after one cycle of chemotherapy: (a) Gd-DTPA contrast-enhanced sagittal slice and (b) T2-weighted sagittal slice. Arrows point to vitamin A fiducials.

Fiducial at position 1 appeared on axial image 106 and fiducial at position 11 appeared on image 206. Thus, every tenth image was chosen to approximate a DOS measurement point.

Corresponding DOS-derived results for the 11 measurement positions in Fig. physiological and (c) scattering parameters were determined at 1-cm intervals over the lesion and surrounding tissue. Normal tissue physiological (d) and scattering parameters (e) taken on the identical location on the contralateral breast at 2.0-cm intervals. Error bars represent standard deviation of repeat measurements.

7 Date of download: 9/19/2016 Copyright © 2016 SPIE. All rights reserved. Maximum intensity projections of the lesion (a) after one cycle of chemotherapy and (b) after four cycles of chemotherapy. The lesion measures 3.7×3.9×3.9cm in (a) versus 3.1×3.5×2.8 in (b).

8 Date of download: 9/19/2016 Copyright © 2016 SPIE. All rights reserved. Enhancement kinetic maps for the lesion (a) after one chemo cycle and (b) after four chemo cycles. Blue (dark gray) represent progressive enhancement and yellow (light gray) pixels correspond to contrast agent washout.

Opt. 2005;10(5):051503-051503-9. doi:10.1117/1.2070147

9 Date of download: 9/19/2016 Copyright © 2016 SPIE. All rights reserved. Comparison of DOS-derived (a) water content, (b) total hemoglobin concentration, (c) lipid content, and (d) tissue oxygen saturation for the lesion after one cycle of chemotherapy and four cycles of chemotherapy. The full width half maximum (FWHM) is indicated on each linescan.
