Impact of 1024‐Matrix Size on Perforating Artery Visualisation in Cerebral Computed Tomography Angiography Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...

Comparison of Low‐Iodine Concentration Quantification Accuracy and Contrast‐To‐Noise Ratio Across Three Dual‐Energy CT Techniques: A Phantom Study

Journal of Medical Radiation Sciences, EarlyView.
Using a clinical abdominal CT protocol, all three DECT techniques accurately quantified iodine. Rapid kV‐switching achieved the lowest detectable and quantifiable iodine concentrations, while dual‐layer DECT provided the highest normalised contrast‐to‐noise ratio on 40‐keV virtual monoenergetic images.

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...

Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

Journal of Medical Radiation Sciences, EarlyView.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Your C‐Arm May Be Dose Optimised but Is Your Surgical Procedure? The Evaluation and Dose Optimisation of Positioning Aids Used in Paediatric Image Guided Surgery

Journal of Medical Radiation Sciences, EarlyView.
This study objectively evaluated the impact of positioning aids on radiation dose and image quality (IQ) in paediatric image guided surgery (IGS) and the potential for dose optimised imaging via the choice of positioning aid type selected for clinical use.
