Journal ArticleDOI
Radiosensitization and Stromal Imaging Response Correlates for the HIF-1 Inhibitor PX-478 Given with or without Chemotherapy in Pancreatic Cancer
David L. Schwartz,James A. Bankson,Robert Lemos,Stephen Y. Lai,Arun K. Thittai,Yi He,Galen Hostetter,Michael J. Demeure,Daniel D. Von Hoff,Garth Powis +9 more
TL;DR: PX-478 is a mechanistically appealing and potentially clinically relevant enhancer of pancreatic cancer radiosensitivity, inhibiting tumor and stromal HIF-1 proangiogenic signaling and reducing the innate radiation resistance of hypoxic tumor cells.
Journal ArticleDOI
Axial-shear strain elastography for breast lesion classification: further results from in vivo data
Arun K. Thittai,Jose-Miguel Yamal,Louise M Mobbs,Christina M. Kraemer-Chant,Srinivasa Chekuri,Brian S. Garra,Jonathan Ophir +6 more
TL;DR: The results demonstrate that the NASSA feature derived from ASSE has the potential to improve BIRADS breast lesion classification of fibroadenoma and malignant tumors.
Journal ArticleDOI
Axial–Shear Strain Distributions in an Elliptical Inclusion Model: Experimental Validation and in vivo Examples With Implications to Breast Tumor Classification
TL;DR: Axial-shear strain fill-in inside an inclusion may be a unique signature of stiff, loosely bonded, ellipsoidal or elongated inclusions at non-normal orientations that may be useful as a marker of benignity of benign breast lesions that are generally stiff, elongated and loosely bonded to the host tissues.
Journal ArticleDOI
Elastography: A decade of progress (2000-2010)
TL;DR: The specific purpose of this review is to describe the progress of the work on elastography at the University of Texas Medical School-Houston in the past decade, and to relate it to earlier work on this topic in the pre- ceding decade.
Journal ArticleDOI
Visualization of HIFU-induced lesion boundaries by axial-shear strain elastography: a feasibility study.
TL;DR: It is demonstrated that it is feasible to reliably visualize HIFU lesion boundaries using ASSE, and it was shown that ASSE enables high-contrast visualization of a "thin" untreated region in between multiple fully-treated HifU-lesions.
