Abstract

To determine if dynamic contrast-enhanced (DCE)-magnetic resonance imaging (MRI) parameters such as permeability surface area (PS) and blood volume (BV) allow differentiating between new head and neck (HN) cancer, recurrent HN cancer, and post-treatment benign changes. A total of 35 patients with newly diagnosed, recurrent, and benign post-treatment benign changes underwent DCE-MRI. PS and BV were calculated. PS values of the lesion were 2.3×10(4)±5.8×10(4) for the newly diagnosed cancer group, 3.3×10(4)±1.7×10(4) for the recurrent cancer group, and 4.8×10(4)±8.1×10(4) for the post-treatment benign change group (P=.031). Post-treatment benign changes in the HN region had significantly high permeability property than newly diagnosed or previously treated recurrent tumor.

Cancer Imaging

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
