What tomorrow brings? October 22, 2007

Posted by tomography in Nuclear Medicine, PET, Radiology, SPECT, Tomography, What tomorrow brings?.

rtgwifehandThe radiologist who sits in a dark room, interpreting films and rendering a report that someone looks at hours later is becoming a thing of the past. Well, does it?
Of course, in this way, it couldn’t work nowadays, in the 2nd millenium – though we should not forget some poor parts of the world, where
some 20-30-40 year old machines are still in use . Basicly Konrad Roentgen’s X-ray was very important in past and shall be in the future, as it started a revolution many years ago, – which we still witness – diagnostic imaging.




Since then, his invention went through a great evolution. Just take a look at the latest X-ray machines. They look nice, they work fine…, but they simply do not cover all the basis. As time went by, came new ideas, so we have CT and MRI in our hands (for many years fortunately). CT and MRI are sensitive in defining that disease is present, but they aren’t specific in determining what particular type of disease may be present. PET was the answer as it really brought it’s dramatic change. The increased metabolic activity not only confirms that cancer is present but it also provides evidence of staging or metastasis beyond the primary. Utilization of PET began in the 1990s. (SPECT has been around for decades, and it is preferred over PET in cardiac cases.) PET and SPECT are both basic gadgets in nuclear medicine, which combines chemistry, physics, mathematics, computer technology, and medicine in using radioactivity to diagnose and treat disease. Nuclear medicine procedures are safe, they involve little or no patient discomfort and do not require the use of anesthesia. Finally, CT-MRI and PET-SPECT found each other in a good working marriage, so one of today’s high-end stuff is PET-CT.

Can we go further? What is the next step?

Many say, that the most exciting development is the coming of molecular medicine. By understanding the molecular basis of disease and developing methods to detect and treat changes in the body at the molecular level, physicians will be able to identify diseases in the earliest possible stages. Cancer is one area experts already are seeing progress.


Molecular imaging is poised to become the future of nuclear medicine. The role of the nuclear imaging specialist in molecular therapy is to provide detailed information regarding the nature of biologic processes using radiopharmaceuticals in concert with positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging.

How about nanomedicine?

Nanomedicine may be defined as the monitoring, repair, construction and control of human biological systems at the molecular level, using engineered nanodevices and nanostructures. Once nanomachines are available, the ultimate dream of every healer, medicine man, and physician throughout recorded history will, at last, become a reality. Programmable and controllable microscale robots comprised of nanoscale parts fabricated to nanometer precision will allow medical doctors to execute curative and reconstructive procedures in the human body at the cellular and molecular levels. But the ability to direct events in a controlled fashion at the cellular level is the key that will unlock the indefinite extension of human health and the expansion of human abilities.

dear future doctors, i came across your blog because i am conducting a research for my second international event:synchronized breastfeeding worldwide on october 11. i am one of the only five lactation consultants in the philippines and i got interested in your blog not only about your celebration of breastfeeding awareness day but also your perception on how to prevent diseases. have you heard of the group physicians committee for responsible medicine (www.pcrm.org) or dr. john mcdougall? how abt the biggest study linking diet and cancer done in china by prof t.colin campbell? i hope you will have the time to read about these information. let these words inspire you: “Let thy food be thy medicine and let medicine be thy food.” — Hippocrates, the father of medicine. “The doctor of the future will give no drugs but will interest his patients in the care of the human body, in diet, and in the cause and prevention of human disease.” — Thomas Edison. keep in touch! i want to send you more materials and maybe you can also organize a site for the synchronized breastfeeding. may you be blessed with more positive energies to achieve your goals! from nona d. andaya-castillo, ibclc (temporarily in new york) p.s. my daughter will also be in Debrecen this year to compete in the European Grand Prix on Chorale Singing as a member of the University of the Philippines Singing Ambassadors. btw, she was breastfed for more than two years. 🙂

Nona, thank you for your inspiring comment! We will look into the information you suggested. The words of Edison and Hippocrate are very good, I will probable use them in my future posts.
Please, do send us more materials. You will find our email address in the About Us section. Looking forward to hearing from you more, and we wish good luck to your daughter. Maybe someday she will study medicine in our school! 🙂
If you have more information on the worldwide breastfeeding day, I would be more than happy to write something about that in my post, and maybe we can do a little interview about that. Have a nice week and don’t be a stranger!

Great site NM has evolved so far, check out this article on PET/MRI

I’ll be checking back soon!
