چکیده
Multi-color gold-nanoparticle-based tags (nanotags) are synthesized for combined surface-enhanced Raman spectroscopy (SERS) and x-ray computed tomography (CT). The nanotags are synthesized with quasi-spherical gold nanoparticles encoded with a reporter dye (color), each with a unique Raman spectrum. A library of nanotags with six different colors were synthesized for a range of gold nanoparticle sizes and an optimum size has been established to yield the largest SERS intensity and x-ray attenuation that is higher than the iodinated CT contrast agents used in clinics. Proof-of-principle in vivo imaging results with nanotags are presented that, for the first time, demonstrates the combined in vivo dual modality imaging capability of SERS and CT with a single nanoparticle probe. S Supplementary data are available from stacks.iop.org/Nano/21/035101/mmedia (Some figures in this article are in colour only in the electronic version)

[68Ga]Ga-PSMA-11 PET/CT for staging and patient management of high-risk prostate cancer: A single-center experience from Iran
Introduction: Accurate staging plays an important role in management of patients with prostate cancer especially in high-risk group. Today, [68Ga]Ga-PSMA-11 PET/CT should be considered as the preferred imaging tool for treatment planning and initial staging of the disease. Methods: A total number of 628 patients with prostate cancer referred to...
