The coronavirus disease 2019 (COVID-19) pandemic underscored the need for the development of tools that can visualize immune system activity in the context of viral inflammation. Although [18F]FDG PET ...

Today's medical imaging technologies are expected to furnish anatomic, physiologic, molecular, and genomic information for accurate disease diagnosis, prediction of treatment response, and development ...

The purpose of this Procedure Guideline is to assist physicians in recommending, performing, interpreting, and reporting the results of SPECT/CT for imaging of adult and pediatric patients. SPECT is a ...

SPECT is a rapidly changing field, and the past several years have produced new developments in both hardware technology and image-processing algorithms. At the component level there have been ...

The accuracy of myocardial perfusion SPECT improves with attenuation correction. Algorithms for attenuation correction in hybrid SPECT/CT systems have the potential for misregistration of emission and ...

Myocardial perfusion SPECT is a well-established clinical tool that provides diagnostic and prognostic information about coronary artery disease. Attenuation correction is now recommended to improve ...

High expression of prostate-specific membrane antigen (PSMA) is not limited to prostate cancer but can be found in other tumor entities, such as hepatocellular carcinoma (HCC), and could possibly be ...

The radionuclide gastric-emptying study has long been the standard method for measuring gastric motility. However, clinicians increasingly express concern about the lack of standardized methodology ...

Time-of-flight (TOF) PET uses very fast detectors to improve localization of events along coincidence lines-of-response. This information is then utilized to improve the tomographic reconstruction.

TO THE EDITOR: We refer to the recent Invited Perspective which proposes that there is now a reduced role for V/Q scintigraphy in the detection of pulmonary embolism (PE) given the emergence of CT ...

The radionuclide gastric-emptying study has long been the standard clinical diagnostic test for the detection of gastroparesis. Both solid and liquid studies have been used over the years, either as ...

This study described and validated a new solid-state single-photon γ-camera and compared it with a conventional-SPECT Anger camera. The compact new camera uses a unique method for localizing γ-photon ...
