Hyperenhancing Prostate Cancer

Some prostate cancers exhibit intense hyperenhancement due to angiogenesis. This color map depicts a hyperenhancing focus within a human prostate corresponding to a prostate cancer.

Dynamic Enhancement within a breast cancer

This is a clinical image from a patient with a vascular breast cancer. The time signal curve demonstrates the rapid enhancement within the tumor.

High resolution 3T image of a mouse

This is a coronal view through a mouse taken within a human MRI unit using a specially designed high resolution mouse coil.

Sentinel Lymph Node Imaging in Animal Breast Cancer Model

This image demonstrates the lymphatic channels and sentinel nodes draining a breast tumor implanted in a mouse mammary pad. The agent used is a gadolinium labeled dendrimer nanoparticle developed in the MIP

Implanted colon cancer xenograft in a mouse

This image is typical of images obtained using the 4.7T Bruker magnet after the administration of Gadolinium chelate contrast intravenously. Note the heterogeneous enhancement within the tumor and the fluid-fluid level within the bladder.

Peritoneal metastases by optical molecular imaging

This is an image of ovarian cancer metastases in the peritoneum of a mouse. An optical proble that targets ovarian cancer (GSA-RhodamineGreen) demonstrates very tiny lesions. This type of probe may assist surgeons in debulking Stage III Ovarian cancer
