INTRODUCTION

Modern medicine requires modern technology.

• Discovery of x-rays in 1895

• Ultrasound, CTs, PETs and MRIs have revolutionized medicine, allowing radical invasive surgeries

• What’s the latest great advancement?

BACKGROUND INFORMATIONBolle, Volgyes,

Rissi and Hines, particle physicists at the University of Oslo in Norway

(Vogt, Vngve)

TECHNOLOGY

CTComputerized Tomography

MRIMagnetic Resonance Imaging

PETPositron Emission Tomography

X-rays Magnets Radioactive positrons

Structures Structures Functions

Image/detail clear Image/detail clearest Image/detail not clear

15-20 minutes 30 minutes 30 minutes-2 hours

Least expensive More expensive Most expensive

(Dolson, Laura)

ADVANTAGES

Higher image quality and soft-tissue contrasta faster diagnosis with increased accuracy

Reduce radiation exposure

Procedure takes less timeone scan instead of two

DISADVANTAGESDifferences in procedures/preparations adds time

Combining them might degrade the performance of either

Expensive

Advanced training for staff

Space constraints & RetrofittingRedo spaces for extra weight/support spaces (uptake rooms)

AVAILABILITY AND USE

• Currently, 3 companies declare availability of PET/MRI devices: • PHILIPS, SIEMENS, & GE

• Presently, there are only ~30 machines in use •Mainly at research institutions

CONCLUSION

PET/MRI scanners could

• Revolutionize/replace current scanning procedure/machinery

• likely impact clinical practice within the next few years

The PET/MRI has great life-saving, industry-altering potential.
