I really like new technology, especially when it offers a very obvious advantage for patients. I recently heard about a new CT scanner that is so fast, it dramatically reduces radiation exposure for patients and can take crisp images of moving organs (like the heart). I asked to speak with Siemens’ VP of Sales and Marketing, Dr. André Hartung, to find out about the new Somatom Definition Flash Dual Source CT Scanner (it takes longer to say the machine’s name than to scan your entire body). Of course, I invited my Medgadget friend, Gene Ostrovsky, to join the call. I’ve included a “bonus track” for more advanced readers at the end of this blog post. Enjoy!

Dr. Val: When would a doctor want to use a CT scanner instead of an MRI machine?

Hartung: CT images are especially good at detecting cancer. Also, because CT scans can be done so quickly, they are also useful diagnostic tools for stroke, heart attack, or when a patient is in critical condition – when every second counts.

Dr. Val: You said that CT scans are based on x-ray technology. How much radiation exposure does the average CT scan cause?

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
