Independent verification of vendor‐issued dosimetric data for 106Ru brachytherapy using diode detectors with traceability to external beam standards for absorbed dose to water

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Independent verification of the manufacturer‐provided dosimetry data for 106Ru ophthalmic brachytherapy applicators is crucial for safe and accurate treatment, yet a standardized, traceable method for clinical absolute dosimetry has been lacking. Purpose This work establishes a complete framework for traceable absorbed dose to water

Direct estimation of activity concentration in regional voxels with application to 177Lu peptide receptor radionuclide therapy

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Quantitative SPECT in radionuclide‐therapy is limited by partial‐volume effects (PVEs). The implementation of regional voxels (r.v.), estimating mean activity concentrations in regions directly from projections, offers a promising alternative for the geometry‐specification to reduce PVEs.

Impact of partial volume correction on radiomics reproducibility in theranostic SPECT/CT imaging

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background: Radiomics has shown potential for quantitative characterization of tumors in molecular imaging; however, its clinical translation in theranostic 177Lu SPECT/CT remains limited due to poor robustness of extracted features to reconstruction variability and partial volume effects.

Pulmonary Transit Time Can Be Accurately Quantified From Non‐Arterial Input Function Series in First‐Pass Cardiac Perfusion MRI

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2207-2213, April 2026.
ABSTRACT Purpose Previous studies suggested that arterial‐input‐function (AIF) images are necessary to avoid signal saturation for pulmonary transit time (PTT) measurements. This study challenges that notion by investigating whether PTT can be accurately measured using blood pool signals from myocardial enhancement (non‐AIF) images during resting first‐

Cutting‐edge advances in bicyclic peptide‐based radiotracers for cancer imaging and theranostics

VIEW, Volume 7, Issue 2, April 2026.
Bicyclic peptides, a burgeoning subset of bicyclic macrocycles, are characterized by two loops stabilized through three linkages of the central chemical scaffolds. As an immense potential platform for radiotracers development, bicyclic peptide‐based radiotracers have yielded encouraging results in preclinical and clinical trial studies.
