Introduction:
Sometimes seeing things from the outside does not tell the whole story. It might look fine on the outside but inside all may not be well. With this in mind, nuclear diagnostic imaging is an area of radiology that allows physicians to see from the outside how the body is working inside. Nuclear medicine is a medical specialty that can detect gamma radiation coming from inside the patient’s body after the injection of the radioactive material. Thus, determining the cause of medical problems based on organ function. Gamma radiation can be detected by devices called gamma cameras. The sensing elements in these cameras are called radiation detectors. Scintillation detectors and semiconductor detectors are the most commonly radiation detectors used in nuclear measurement systems to convert radiation energy into an electronic signal.
The main purpose of this work was to compare the efficacy in medical imaging of the scintillator based camera i.e. Hybrid Gamma Camera (HGC) developed in the Space Research Centre, University of Leicester and the XRI-UNO CdTe semiconductor based detector provided by X-Ray Imatek Company

Conclusion:
Overall, the performance of the HGC and XRI-UNO were evaluated and compared. The results show that the HGC has a system spatial resolution higher than the XRI-UNO when fitted with identical pinhole collimators. The biggest advantage of semiconductors is that they are able to operate at room temperature and which allows for smaller more compact detectors, as they are does not require to be cooled. However, the sensitivity of the XRI-UNO was found to be less than that of the HGC making it less suitable for clinical use. These studies encourage us to carry out further evaluation in preparation for HGC uses in surgical theatre setting rather than XRI-UNO
