“…In recent years, alternatives to the Anger logic have been proposed (see section Detector Technology for CT, SPECT, and PET). However, the comparably high costs involved, mainly from the use of solid state detectors, restricts adoption in smaller systems designed for special applications, such as cardiac [35], brain [36] or pre-clinical imaging [37].…”

State-of-the-art patient management frequently requires the use of non-invasive imaging methods to assess the anatomy, function or molecular-biological conditions of patients or study subjects. Such imaging methods can be singular, providing either anatomical or molecular information, or they can be combined, thus, providing "anato-metabolic" information. Hybrid imaging denotes image acquisitions on systems that physically combine complementary imaging modalities for an improved diagnostic accuracy and confidence as well as for increased patient comfort. The physical combination of formerly independent imaging modalities was driven by leading innovators in the field of clinical research and benefited from technological advances that permitted the operation of PET and MR in close physical proximity, for example. This review covers milestones of the development of various hybrid imaging systems for use in clinical practice and small-animal research. Special attention is given to technological advances that helped the adoption of hybrid imaging, as well as to introducing methodological concepts that benefit from the availability of complementary anatomical and biological information, such as new types of image reconstruction and data correction schemes. The ultimate goal of hybrid imaging is to provide useful, complementary and quantitative information during patient work-up. Hybrid imaging also opens the door to multi-parametric assessment of diseases, which will help us better understand the causes of various diseases that currently contribute to a large fraction of healthcare costs.

Myocardial perfusion imaging (MPI) is a well-established and widely used imagingtechnique for the assessment of patients with known or suspected coronary artery disease. Pitfalls and artifacts associated with conventional gamma cameras are well known and the ways to avoid and correct them have been described. In recent years solid-state detector dedicated cardiac cameras were introduced and have been shown to offer improved accuracy in addition to new imaging protocols and novel applications. The purpose of this manuscript is to familiarize the readers with the causes and effects of technical, patient related and operator-related pitfalls and artifacts associated with the D-SPECT dedicated cardiac camera with solid-state detectors. The manuscript offers guidance on how to avoid these factors, how to detect them and how to correct better for them, providing high-quality diagnostic images.

“…Regardless of the collimation used, each system also takes advantage of advanced SPECT reconstruction algorithms to further improve the sensitivity of the system. 5,6 One such system uses three pixelated cesium iodide scintillation detectors and fan-beam collimation to increase sensitivity of counts collected from the heart (Cardius X-ACT, Digirad, Poway, CA). In this system, the patient sits upright in a chair that rotates.…”
