“…Due to the emerging role of the CT in hybrid nuclear imaging, the community has to adapt the training curricula of the workforce to provide a sufficient set of competencies to master the new techniques (Beyer et al 2018;Stegger et al 2008;Delbeke et al 2012;Medicine EAoN, Radiology ESo 2012;Bischof Delaloye et al 2007;Fragoso Costa et al 2017;Costa et al 2019) Nuclear medicine technologists (NMT) training curricula varies among European countries (Matos et al 2015) endowing the NMT with different practical skills in the field of nuclear cardiology. Additionally, different acquisition protocols are currently used across Europe (Lindner et al 2016).…”

The use of hybrid systems is increasingly growing in Europe and this is progressively important for the final result of diagnostic tests. As an integral part of the hybrid imaging system, computed tomography (CT) plays a crucial role in myocardial perfusion imaging diagnostics. Throughout Europe, a variety of equipment is available and also different university curricula of the nuclear medicine technologist are observed. Hence, the Technologist Committee of the European Association of Nuclear Medicine proposes to identify, through a bibliographic review, the recommendations for best practice in computed tomography applied to attenuation correction and calcium score in myocardial perfusion imaging, which courses in the set of knowledge, skills, and competencies for nuclear medicine technologists. This document aims at providing recommendations for CT acquisition protocols and CT image optimization in nuclear cardiology.

“…Centre D installed a PET/CT scanner model with a 16.4 cm PET axial field of view and using 4.1 min per bed for scanning the adult patient in comparison to centre C, which used the same scanner model and same scintillation crystal with an axial FOV of 21.6 cm and time/bed scanning of 2.2 min (tables 3 and table 4). Increasing scanner sensitivity may aid in a short scanning time and low 18 F-FDG AA without compromising the diagnostic image quality [34,35]. The proposed Jordan NDRL (303 MBq) was lower than the majority of published NDRL methods for 18 F-FDG whole-body PET/CT examinations, which typically ranged from 235 MBq to 592 MBq (figure 2).…”

Purpose: This study aims to report the findings of Jordanian national diagnostic reference level (NDRL) survey for fluorodeoxyglucose (18F-FDG) and local diagnostic reference level (LDRL) of computed tomography (CT) used for attenuation correction and anatomical localization (AC-AL); and attenuation correction and diagnostic CT (AC-DX) within the context of whole-body WB and half-body HB adult oncology PET/CT scanning.Methods: Two-structured questionnaires were prepared to gather the necessary information: dosimetry data, patient demographics, equipment specification, and acquisition protocols for identified 18F-FDG PET/CT procedures. The NDRL and achievable dose were reported based on the 75th and 50th percentiles for 18F-FDG administered activity (AA), respectively. The LDRL was reported based on the 50th percentile for (CTDIvol) and (DLP). Results: Data from 562 patients from four Jordanian PET/CT centres were collected. The survey revealed that Jordanian NDRL for administered activity (AA) (303 MBq) was within the acceptable range compared to the published-peer NDRL data (240 to 590 MBq). However, the 18F-FDG AA varied across the participated PET/CT centres. The reported LDRL CTDIvol and DLP of CT used for (AC-AL) was 4.3 mGy and 459.3 mGy.cm for HB CT scan range, and 4.1 mGy and 659.9 mGy.cm for WB CT scans. The reported LDRL for CTDIvol and DLP for HB CT was higher when compared with the United Kingdom (3.2 mGy and 310 mGy.cm). Concurrently, in the context of WB CT, the reported values (i.e., CTDIvol and DLP) were also higher than both Kuwait (3.6 mGy and 659 mGy.cm) and Slovenia (3.6 mGy and 676 mGy.cm). The reported HB CT(AC-DX) was higher than Nordic, New Zealand and Swiss NDRLs and for WB (AC-DX) CT it was higher than Swiss NDRLsConclusion: This study reported the first Jordanian NDRL for 18F-FDG and LDRL for HB and WB CT associated with 18F-FDG PET/CT scans. This data is useful for Jordanian PET/CT centres to compare their LDRL to the suggested DRLs and utilize it in the process of optimising CT radiation doses.

Background Positron emission tomography-computed tomography (PET/CT) is a widely utilized hybrid imaging technique that combines functional and anatomical information. To ensure the safe and effective use of this imaging modality, Diagnostic Reference Levels (DRLs) have been established as standardized benchmarks for assessing and managing radiation doses in clinical practice. Several studies have reported DRLs for different radiotracers and imaging modalities, including PET/CT. However, there is a need for country-specific DRL data that reflect national clinical practices. While existing literature provides insights into DRLs for PET/CT procedures in various settings, there is a lack of PET/CT DRLs specific to the Jordanian context. Given the variations in patient populations, equipment specifications, and clinical protocols, it is crucial to establish NDRLs and local DRLs (LDRLs) in Jordan. Therefore, the study aimed to derive the country-specific reference levels for fluoride-18 fluorodeoxyglucose (18F-FDG) PET/CT scans in Jordan. Results The survey revealed that Jordanian NDRL for administered activity (AA) (303 MBq) was within the acceptable range compared to the published-peer NDRL data (240 to 590 MBq). However, the 18F-FDG AA varied across the participated PET/CT centres. The reported LDRL CTDIvol and DLP of CT used for attenuation correction and anatomical localization (AC-AL) was 4.3 mGy and 459.3 mGy.cm for half-body (HB) CT scan range, and 4.05 mGy and 659.9 mGy.cm for whole-body (WB) CT scans. The reported LDRL for CTDIvol and DLP for HB CT was higher when compared with the United Kingdom (3.2 mGy and 310 mGy.cm). Meanwhile, it remained higher than both Kuwait (3.6 mGy and 659 mGy.cm) and Slovenia (3.6 mGy and 676 mGy.cm) for WB CT. The reported HB attenuation correction diagnostic CT(AC-DX) CT was higher than previously identified peer-reviewed NDRL data and lower than Slovenia for WB AC-DX CT acquisition protocols. Conclusion This study reported the first Jordanian NDRL for 18F-FDG and LDRL for HB and WB CT associated with 18F-FDG PET/CT scans. The data provides a valuable reference point for Jordanian PET/CT centres to compare their LDRL with the suggested DRLs. By utilizing this data, centres need to optimize CT radiation doses and tailor them to ensure appropriate image quality.
