This global survey reveals SPECT/CT imaging is not routine and underutilizes CT capabilities. Findings highlight the need for SPECT/CT training and standardization to improve diagnostic imaging.
Area of Science:
- Medical Imaging
- Nuclear Medicine
- Radiology
Background:
- Single-photon emission computed tomography/computed tomography (SPECT/CT) integrates functional and anatomical imaging.
- Standardization of SPECT/CT protocols is needed to optimize its clinical utility.
Purpose of the Study:
- To survey global clinical SPECT/CT operations.
- To identify variations in SPECT/CT imaging protocols and utilization.
- To inform the standardization of SPECT/CT procedures.
Main Methods:
- An international web-based survey was distributed to SPECT/CT users.
- The survey included 71 questions on demographics, operations, utilization, and protocol variations.
- Data were collected from 117 imaging centers worldwide.
Main Results:
- SPECT/CT is not routinely used in most centers; 51% perform it routinely, 49% ad-hoc.
- The CT component is primarily for anatomical localization, not high-quality CT imaging.
- Significant inter-site and inter-examination variability in protocols was observed.
Conclusions:
- SPECT/CT is not fully integrated into routine nuclear medicine practice.
- The diagnostic potential of CT components in SPECT/CT is underutilized.
- There is a clear need for SPECT/CT training and protocol standardization.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
