Introduction: The development of nanomedicine, during the last 10 years have given rise to novel delivery systems among which multifunctional platforms called nanotheranostics that are designed to simultaneously diagnose and cure cancer. These systems can be built using the large panel of biocompatible and biodegradable materials. The recent advances of imaging modalities even enable targeted nanotheranostics to probe molecular structures on specific cells opening the doors to personalized cancer therapy. Areas covered: This review presents the different requirements nanotheranostics should fulfill to achieve an optimized anticancer therapy. It focuses on two imaging modalities: MRI and ultrasonography used to visualize drug delivery, release, and efficacy. The advantages and limitations of these two methods are considered. The review will enable the readers to virtually tune a nanotheranostic system according to the nature of the targeting tissue and the availability of imaging modality. Expert opinion: Despite great perspectives, described for nanotheranostic systems in personalized cancer therapy, the imaging techniques still face technological issues, such as high sensitivity and good spatial and temporal resolutions. Active targeting should consider better specificity and low immunogenicity of the ligand selected, to be more efficient.
