New accept rice technology can diagnose small tumor

PET (functional metabolization is shown picture) , CT (anatomize a structure to show picture) , nuclear magnetic resonance has been the advanced method that diagnoses tumor at present, but these detecting the tumour that the technology can discover 1 centimeter of above only, helpless however to smaller tumor, and development gave researcher recently one kind uses accept rice technology, can carry fine of many radiography agent definitely to tumor place, the millimeter class tumour that makes discover hard originally immediately darling " reveals original shape " .

To tumor patient, early discovery early treatment is the biggest undoubtedly live safeguard, but on one hand with current examination method, 1 centimeter of the following tumour discover very hard, the leakage examine that has some of tumor on the other hand by accident examine rate is extremely high, make many small tumor became the fish of escape unpunished, lost first-rate to treat an opportunity, and without the tumour that achieve a gender the research of inchoate diagnostic technology succeeds this the diagnostic rate that can raise inchoate and small tumor greatly.

When tumor grows 1~2 millimeter above, its periphery can grow an a few new students are hemal, supply in these hemal nutrition below, tumor expands with respect to development of can ceaseless " " , and normal and mature organization does not have this kind of characteristic, new student blood-vessel can say is a striking tumor feature, accordingly, down new student blood-vessel " of this " cane can find tumor " of this " melon, this kind of diagnostic method applicably at all hypostatic tumour.

But, how to make many radiography agent reachs tumor place well and truly, making its develop comes out is a medical difficult problem all the time. The development of accept rice technology solved this problem successfully well.

This kind detects the tool resembles " of miniature " lorry, its diameter still is less than 100 accept rice (one accept rice is equal to billion 1/0 meters) , because this can be in human body organization,freedom moves back and forth, it is carrying grain of accept rice radiography, in high-tech navigator point to get, accurate lock decides target to the element, carry its tumor position, and its collect action magnified develop effect, make the small tumor that discovers hard originally is shown.

This technology but uncover diameter is the smallest the small tumor that is 3 millimeter, it still can be used at the distinction of tumor and other disease to diagnose. Professor Zhou says, this technology already gained the success that the animal experiments at present, can finish as soon as possible clinical before experiment, can throw before long clinical use.
