Obese patient imaging: Potential dose reduction with photon‐counting CT

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Photon‐counting CT (PCCT) offers key advantages over energy integrating detector CT (EID‐CT), especially in low‐dose scans and imaging larger patients. As obesity rates rise, minimizing image noise is critical for diagnostic accuracy.

K‐Edge imaging using a clinical dual‐source photon‐counting CT system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Photon‐counting CT (PCCT) enables K‐edge imaging, an advanced multi‐material decomposition technique that requires multiple energy bins to perform decomposition unconstrained by physical assumptions. The clinical implementation of K‐edge imaging applications like dual‐contrast imaging could lead to reductions in radiation dose and ...

An interpretable radiomics–deep learning nomogram from whole‐body bone scintigraphy for MDP‐avid bone metastasis prediction in NSCLC

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Whole‐body bone scintigraphy (WBS) remains a widely used first‐line screening tool for bone metastasis, but differentiating MDP‐avid metastatic lesions from benign bone abnormalities in non‐small cell lung cancer (NSCLC) remains challenging. Purpose To develop and externally validate a radiomics and deep learning bone signature (RDB)

Comparison of three commercial multi‐energy CT and electron density phantoms for iodine quantification and tissue substitute characterization

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Multi‐energy computed tomography (MECT) and electron density (ED) phantoms are designed for evaluating the performance of CT scanners. They include substitute materials representing the energy‐ and material‐dependent CT numbers of different organs, tissues, or contrast agents.
