House committee hearing on Philly VA surprisingly productive

I have finally watched the entire House Veterans’ Affairs Committee hearing on the prostate brachytherapy program at the Philadelphia VA hospital. You can find the webcast, along with statements for the record, at the committee website. I was pleasantly surprised by the lack of grandstanding by the committee members and their restraint in [...]

House bill to ramp up US molybdenum-99 production

We are finally seeing action from the US government to address the molybdenum-99 shortage. Congressmen Edward Markey (D-Mass.) and Fred Upton (R-Mich.), have introduced a bill to authorize $163 million over five years to create a domestic source of the medical imaging isotope. Unfortunately, the funding comes too late to ameliorate the current [...]

Really? A network jack?

Another unbelievable report in the Philadelphia Inquirer about the VA prostate brachytherapy debacle. As I wrote before, the errors in the placement of the radioactive seeds went undiscovered for so long because post-implant dosimetry was not performed. This involves CT scanning the patient, finding the positions of the seeds and calculating the ultimate [...]

So says Princeton University Archivist Dan Linke. While moving Princeton’s chemistry library to a new building, library staff [...]

Quick update on the medical isotope shortage

The Ontario Ministry of Health has just issued a notice that the Chalk River nuclear reactor will be out of service until the end of 2009 at least. This reactor generated half of the world’s supply of Tc-99m, used in medical imaging studies. The problem is about to get worse as one of [...]

What is Radiation Therapy (Part 5): What happens in the patient …

In the last post in this series, I talked about how we can shape the beam of radiation in order to conform it to the shape of the tumor. If all we had to do is to shape the beam, point and shoot, this job would be easy. Unfortunately, it’s a lot more [...]

Not much new from the Philadelphia VA hearing

I have taken a quick listen to the Senate Veterans’ Affairs Committee field hearing in Philadelphia on Monday (you can find the mp3 files here, along with witness statements). Nothing came out that was not already in the NRC report. However, Sen. Specter indicated that a hearing of the full committee in Washington [...]
