Saharkhiz N, Ha R, Taback B, Li X, Weber R, Nabavizadeh A, et al.
Sci Rep
. 2020 Sep;
10(1):15254.
PMID: 32943648
Non-invasive diagnosis of breast cancer is still challenging due to the low specificity of the imaging modalities that calls for unnecessary biopsies. The diagnostic accuracy can be improved by assessing...

Ultrasound Med Biol
. 2020 Sep;
46(12):3393-3403.
PMID: 32917470
We applied sub-Hertz analysis of viscoelasticity (SAVE) to differentiate breast masses in pre-biopsy patients. Tissue response during external ramp-and-hold stress was ultrasonically detected. Displacements were used to acquire tissue viscoelastic...

Theranostics
. 2020 Apr;
10(10):4614-4626.
PMID: 32292518
: Poor specificity and predictive values of current cross-sectional radiological imaging methods in evaluation of pancreatic adenocarcinoma (PDAC) limit the clinical capability to accurately stage the tumor pre-operatively and provide...

Harmonic Motion Imaging of Pancreatic Tumor Stiffness Indicates Disease State and Treatment Response
Payen T, Oberstein P, Saharkhiz N, Palermo C, Sastra S, Han Y, et al.
Clin Cancer Res
. 2019 Dec;
26(6):1297-1308.
PMID: 31831559
Purpose: Pancreatic ductal adenocarcinoma (PDA) is a common, deadly cancer that is challenging both to diagnose and to manage. Its hallmark is an expansive, desmoplastic stroma characterized by high mechanical...

Nabavizadeh A, Bayat M, Kumar V, Gregory A, Webb J, Alizad A, et al.
Sci Rep
. 2019 Apr;
9(1):5737.
PMID: 30952880
Benign and malignant tumors differ in the viscoelastic properties of their cellular microenvironments and in their spatiotemporal response to very low frequency stimuli. These differences can introduce a unique viscoelastic...

Med Phys
. 2018 Sep;
45(11):5244-5250.
PMID: 30178474
Purpose: Noninvasive quantitative assessment of coagulated tissue during high-intensity focused ultrasound (HIFU) ablation is one of the essential steps for tumor treatment, especially in such cases as the Pancreatic Ductal...
