Thanks merwether for the valuable feedback. Actually Chapter 11 bankruptcy does not sound all that bad for the company. "Filing Chapter 11 bankruptcy allows businesses to stay open and continue operating while reworking their financial obligations. Filers are able to put forth a reorganization plan, which can include downsizing and plans to reduce their expenses" (Source- https://www.investopedia.com/ask/answers/061815/what-are-differences-between-chapter-11-and-chapter-13-bankruptcy.asp ) It appears that Viewray ,in fact, is taking these steps now so I would not write them off at this time. Their main asset is the future demand for what the MRdian machine can provide.
From what I've researched, the Gold Standard is to have an mpMRI guided biopsy rather than an MRI guided one. Definition: mpMRI means Multiparametric magnetic resonance imaging. This technique "is also claimed to allow more accurate diagnosis with higher detection rates, using fewer biopsies. It can pick up cancers with a Gleason score of 7 or above, and it is also better at detecting anterior tumors missed by a TRUS systematic biopsy. It is especially useful in patients undergoing repeat biopsies, with a 41% pick-up rate of cancers on mpMRI-guided biopsies, and with 87% of these being of clinical importance.
What is also important is that lesions detected on mpMRI are also more likely to be aggressive." (Source--https://www.news-medical.net/health/Types-of-Prostate-Biopsy.aspx) I am tilting toward MRdian since I don't think it requires fiducials to be inserted into the prostate like the CyberKnife approach. What are your thoughts?
