Hybrid Imaging in Diagnosis

Modern patient treatment usually demands the use of non-invasive imaging techniques to evaluate the anatomy, function, or molecular-biological states of patients or research participants. Such imaging techniques can be used alone to provide anatomical or molecular information, or they can be coupled to provide "anato-metabolic" data. In order to enhance diagnostic accuracies, patient comfort, and diagnostic confidence, hybrid imaging refers to image acquisitions on systems that physically integrate complementary imaging modalities. Leading thinkers in clinical research were responsible for the physical fusion of traditionally separate imaging modalities, and it profited from technology advancements that made it possible, for instance, to operate PET and MR next to one another physically. The development of several hybrid imaging systems for use in this evaluation is covered at key points. The development of several hybrid imaging technologies for use in small-animal research and clinical practise is covered in this review's milestones. The introduction of methodological concepts that profit from the availability of complementary anatomical and biological information, such as new types of image reconstruction and data correction schemes, as well as technological advancements that aided in the adoption of hybrid imaging are both given special attention. Hybrid imaging's ultimate objective is to offer helpful, complementary, and quantitative data during patient evaluation. Hybrid imaging also makes it possible to examine illnesses on a multi-parametric level, which will enable us to learn more about the underlying causes of the many conditions that now account for a significant portion of healthcare spending.
