TLDR
The advantages of molecular ultrasound imaging such as high temporal and spatial resolution, non-invasiveness, real-time imaging, relatively low cost, lack of ionizing irradiation and wide availability among the imaging community will further expand its roles in cancer imaging and drug development both in preclinical research and future clinical applications.Abstract:
Angiogenesis, the growth of new blood vessels, plays a critical role in progression of tumor growth and metastasis, making it an attractive target for both cancer imaging and therapy. Several molecular markers, including those that are involved in the angiogenesis signaling pathway and those unique to tumor angiogenic vessels, have been identified and can be used as targets for molecular imaging of cancer. With the introduction of ultrasound contrast agents that can be targeted to those molecular markers, targeted contrast-enhanced ultrasound (molecular ultrasound) imaging has become an attractive imaging modality to non-invasively assess tumor angiogenesis at the molecular level. The advantages of molecular ultrasound imaging such as high temporal and spatial resolution, non-invasiveness, real-time imaging, relatively low cost, lack of ionizing irradiation and wide availability among the imaging community will further expand its roles in cancer imaging and drug development both in preclinical research and future clinical applications.read more

Angiogenesis in cancer, vascular, rheumatoid and other disease
TL;DR: Think of the switch to the angiogenic phenotype as a net balance of positive and negative regulators of blood vessel growth, which may dictate whether a primary tumour grows rapidly or slowly and whether metastases grow at all.

Mechanisms of angiogenesis
TL;DR: Understanding of the molecular basis underlying angiogenesis, particularly from the study of mice lacking some of the signalling systems involved, has greatly improved, and may suggest new approaches for treating conditions such as cancer that depend onAngiogenesis.

Vascular endothelial growth factor: basic science and clinical progress.
TL;DR: Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen in vitro and an angiogenic inducer in a variety of in vivo models and is implicated in intraocular neovascularization associated with diabetic retinopathy and age-related macular degeneration.

Tumorigenesis and the angiogenic switch
TL;DR: A more detailed understanding of the complex parameters that govern the interactions between the tumour and vascular compartments will help to improve anti-angiogenic strategies — not only for cancer treatment, but also for preventing recurrence.
