"With its significant radiation dose reduction and markedly shorter acquisition times, LAFOV PET/CT may emerge as a valuable tool for pediatric cancer predisposition surveillance." - Kevin Fung
buff.ly/4b13L12 (Kevin J. Chung et al.)
LAFOV PET/CT systems have demonstrated effective diagnostic imaging at dramatically lower administered activities โ as low as 0.37 MBq/kg, with ongoing investigations exploring reductions toward 0.1 MBq/kg
Conventional PET systems capture less than 1% of emitted coincidence photons, largely because only a limited portion of the body lies within their axial field-of-view at any given time. By extending the axial coverage to more than 100 cm, LAFOV PET dramatically increases detection sensitivity.
By extending axial coverage beyond 100 cm, these scanners can image the majority of the body in a single bed position, dramatically improving workflow and efficiency.
๐ ๐ผ๏ธ Seeing the big picture - Large-axial field-of-view (FOV) PET/CT
A major milestone in molecular imaging has been the introduction of long-axial field-of-view (LAFOV) PET/CT systems.
Due to its minimal electronic noise, photon-counting CT can image at much lower dose levels without sacrifycing imag quality with reductions reported up to 90% in ultra-high-resolution modes. For children who are more radiosensitive compared to adult population, this is a game changer." - Kevin Fung
"As a paediatric radiologist, the most exciting aspect for me is the potential for substantial radiation dose reduction.
Clinically, it has demonstrated clear advantages in challenging scenarios such as evaluating heavily calcified coronary arteries and visualizing stent lumens, where reduced blooming artifacts and improved resolution enhance diagnostic confidence compared with conventional CT systems.
Since its integration into routine clinical practice in 2021, photon-counting CT has attracted significant attention.

By directly converting each individual X-ray photon into an electrical signal using semiconductor-based detectors, PCD-CT minimizes electronic noise, improves geometric dose efficiency, and enables ultra-high spatial resolution alongside inherent spectral imaging.
Photon-counting detector CT (PCD-CT) represents a fundamental shift in how CT data are acquired.

"This study reinforces the critical role of AI as a complementary "safety net" that standardizes interpretation and ensures more equitable care across different levels of clinical experience." - Amit Gupta

Highly recommend reading this if you are looking for evidence-based ways to optimize prostate imaging workflows.
AI assistance delivered the best overall performance (AUC 0.969; sensitivity 76.5%, specificity 97.2%) and improved agreement with the expert (ฮบ 0.64 โ 0.84), notably by reducing โgray-zoneโ PI-RADS 3 assignments and boosting exact agreement.
In this PROSA-trial screening cohort (499 bpMRIs), the authors compared an expert reader, a less-experienced reader, an FDA/CE-marked AI tool (Quantibยฎ Prostate), and the less-experienced reader with AI supportโusing expert interpretation as the reference.
Bridging the expertise gap: AI-assisted reading of non-contrast prostate MRI is a game-changer for high-volume screening. ๐งโโ๏ธ๐ค๐ค
"The real win here is standardization; when we consistently combine Dixon + DWI + quantitative metrics, marrow disease becomes measurable on MRI, follow-up becomes actionable, and reporting becomes far more reproducible across readers and sites." - Amit Gupta
Standardizing these advanced, radiation-free protocols across imaging facilities is a vital step toward delivering highly objective and precise oncologic care.
Highly recommend saving this open-access review as a practical blueprint for upgrading local bone marrow imaging workflows.
The expert guidelines detail how tailoring whole-body or axial skeleton MRI protocols with standardized T2 Dixon sequences, diffusion-weighted imaging (DWI), and quantitative biomarkers like ADC and fat fraction (FF) significantly improves diagnostic accuracy.
The newly published ESR Essentials by the European Society of Musculoskeletal Radiology (ESSR) firmly establishes MRI as the primary imaging modality for diagnosing, staging, and monitoring oncologic bone marrow involvement.
Are we ready to make bone marrow MRI the defaultโnot the โextra testโโwhen metastatic disease or myeloma is on the table? ๐ฆด๐งฒ๐
