The Ideal Imaging Technology

I saw a lecture recently at the International Paediatric Radiology conference in London by Sam Gambhir from Stanford stating the ultimate medical imaging tool’s characteristics. I’m shamelessly quoting him here as I thought it was such a good slide.

  • Anatomical information
  • Molecular information
  • Spatial resolution of 100-200 microns
  • Intrinsic molecular signal
  • Multiplexing capacity
  • High sensitivity (pM – nM)
  • High throughput
  • Whole body rapidly scanned
  • Low cost
  • Safe, allowing repeat imaging

Radiation doses in CT scanning, should we be taking consent?

The radiation argument continues to heat up (no pun intended…) on both sides of  The Pond. All of the major radiology conferences this year such as RSNA, Chicago and ESR, Vienna had comprehensive lectures and open debate sessions to address the unavoidable topic of radiation dosing. CT scanners have become so ubiquitous and overused by clinicians that the risk benefit equation is being tipped.
