Introduction: Nuclear Scintigraphy is a highly sensitive, alternative imaging modality used in human and veterinary medicine. This modality involves the administration of a radioactive substance (radioisotope) to a patient. Generally, the radioisotope is labeled to a specific compound. This labeled combination is known as a radiopharmaceutical. These radiopharmaceuticals are formulated in vario...

Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution.  The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...

Diagnosis of diseases by different imaging methods can provide complementary information about the functional status of diseased tissues or organs. To overcome the current difficulties in coregistering images from different imaging modalities with a high degree of accuracy, we prepared near-infrared (NIR) monomolecular multimodal imaging agents (MOMIAs) consisting of a heptamethine carbocyanine...

Positron emission tomography (PET) is a method for taking pictures of disease inside sick person’s body, without having to cut them open. In PET imaging, radioactive chemical called radiotracer injected into patient. All radiotracers have two main parts: part that targets the disease, and an unstable atom (radioisotope) emits positive electrons (positrons) as it breaks down (decays). When posit...

Positron emission tomography (PET) are widely accepted and used as an effective medical imaging method. We have studied on the dual radioisotopes C11 Cu60 together by modifying isotopes in Standard cyclindirial PET through GATE simulation. scan proper resolution intervals distances between sources present differences parameters such full width at half maximum (FWHM), intensity contrast.
