Cancer imaging:clinical application,achievements and challenges
Cancer represent a significant global public health concern,posing a substantial threat to human life and health.The enhance-ment of cancer survival rates and prognostic outcomes hinges on the early and precise diagnosis,particularly in the contemporary epoch of precision medicine.Various imaging modalities,such as optical imaging,X-ray,CT,MRI,ultrasound,and nuclear medicine,possess the capability to delineate alterations in tumor function,metabolism,and anatomy across microscopic,mesoscopic,and macroscopic scales.These modalities occupy a crucial role in the initial detection,diagnostic staging,monitoring of treatment,and prognostic evaluation of tu-mors.Despite their significance,numerous challenges persist in the realms of equipment advancement,the research and development of imaging probes/contrast agents,and clinical translation.
