Tuesday’s news reports: February 16, 2009

For the engineers, the scientists, and other technically minded readers, there are a number of very “dense” scientific news reports today.

Chitchian et al. have reported on the application of a technique known as “optical coherence tomography” (OCT) of the prostate nerves as a method that may help to guide surgeons and therefore enhance the likelihood of preservation of the cavernous nerves during prostate cancer surgery.

Makni et al. have published data on a method for automatic, three-dimensional segmentation of the prostate gland based on magnetic resonance imaging (MRI) data. They suggest that this method may offer a new means for accurate localization and contouring of  the prostate in conducting and monitoring radiation procedures.

Kim et al. have suggested that, when using magnetic resonance imaging (MRI) to predict locally recurrent prostate cancer in patients with biochemical failure after radiation therapy, the use of combined T2-weighted imaging (T2WI) in combination with diffusion-weighted imaging (DWI) offers a better diagnostic  performance than T2WI alone. However, it should be noted that T3-weighted imaging is already under investigation for this use in the USA.

Paris et al. have proposed that functional phenotyping and genotyping of circulating tumor cells (CTC) from patients with castration-resistant prostate cancer may be helpful in the future study of advanced prostate cancer.

  1. Is the OCT similar to a CaverMap?

  2. I get the impression that it is a rather more sophisticated system (which doesn’t necessarily make it better). For details on OCT, see the entry on Wikipedia.
