About Us

Quantitative Imaging Core Lab (QICL) of the Department of Radiology at Northwestern University - Feinberg School of Medicine provides consistent, standardized, and high-quality medical image analysis for clinical research trials.

The QICL is co-directed by Vahid Yaghmai, MD and Riad Salem, MD, MBA. Our team includes world's leading experts in Radiology and Interventional Oncology who provide a unique set of knowledge and skills.  

Affiliation with Robert H. Lurie Comprehensive Cancer Center of Northwestern University

Quantitative Imaging Core Lab is affiliated with the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. The Robert H. Lurie Comprehensive Cancer Center is one of only 41 NCI-designated "Comprehensive" cancer centers in the nation and is a NCI designated Center for Quantitative Imaging Excellence (NCI-CQIE). In addition, the Lurie Cancer Center is a founding member of the National Comprehensive Cancer Network (NCCN), an alliance of 23 of the world's leading cancer centers dedicated to improving the quality and effectiveness of care provided to patients with cancer.


We provide a comprehensive set of quantitative imaging services for oncologic clinical trials, in particular for evaluation of responses to cancer therapies. At present, the QICL analyzes medical images for over 30 clinical trials.

Our quantitative imaging services in Oncology include response to therapy assessment for various cancers:

Our sub-specialized expert radiologists provide consultation for best imaging protocols in clinical trials. Many of our radiologists are members of the ACR Appropriateness Criteria expert panels.


Quantitative Imaging Core Lab is equipped with the state of the art imaging solutions for diagnosis, staging, follow-up assessment, and monitoring in oncology. The QICL provides a high level of automation in order to reduce variability and guarantee consistency in quality.

Our imaging solutions provide 2D, 3D, and 4D image analysis capabilities for various study types:

  • Computed Tomography (CT)
  • Magnetic Resonance Imaging (MRI)
  • PET
  • Computed Radiography Images

The QICL makes quantitative measurements of lesions according to accepted techniques and assessment criteria standards such as:


Our research priorities reflect the interests in development and evaluation of new imaging biomarkers and automated imaging solutions to obtain functional and structural characteristics of tumor.
