11C choline PET imaging and MRI tomap prostate cancer recurrence figure
Researchers from the Mayo clinic team,using 11C choline PET imaging and multiparameter magnetic resonanceimaging(MRI) technology, the first successful mapped the patterningfigure ofpostoperative recurrence of prostate cancer.The researchers found that the differentpatternafterprostate cancer recurrencein anatomical, which is beneficial tooptimization of postoperative recurrence of prostate cancer treatment.The studywas published in the Journal of Urology.
Mayo clinic urologist DrJeffrey Karnessaid, "The study for the rise in prostate specific antigen (PSA) testing(also named biochemical recurrence) have important implications for thetreatment of male patients, in such patients, determine the locus of diseaserecurrence very challenging, especially when the PSA in low level."
According to Dr Karnes view, about 30% patientsin the United States, using the surgical removal of the prostate cancer, therewill have a recurrence, and seek treatment.The current imaging technique, suchas traditional CT scanning, insufficient sensitivity can’tensure the recurrencesite,especially when the PSA value is less than 10.
DrKarnessay,the combination of11Ccholine PET scanning and multiple parameterMRI technology, is enough to helpdoctors accurately identify cancer recurrencesiteswhen PSA average in 2.Moreimportantly, after confirmation recurrence site can allowdoctor to selectivesurgery or radiation therapy.
Dr Karnes and his team used this technologycan also describe prostate cancer recurrence model, they found that nearlytwo-thirds of the men cancer recurrence area is limited with pelvis, it couldalso be the goal of radiotherapy.
