Traditionally, patients with asymptomatic, advanced-stage follicular lymphoma were managed with a watchful-waiting approach until disease progression. The 'Watch and Wait' Phase-3 randomised international trial examined whether rituximab could delay the need for treatment and the effect on quality of life (QoL). In this article, we present the long-term results of the QoL aspect of the trial.

Article Synopsis
  • X-ray CT often requires contrast agents to improve soft tissue diagnosis, but traditional agents involve high doses that can be risky for certain patients.
  • Dark-field X-ray imaging offers a more sensitive alternative by using scattered radiation to enhance image contrast, which hasn't yet been fully leveraged for contrast agent innovation.
  • This study shows that high-Z nanoparticles can create better dark-field contrast due to their higher electron density, improving detection sensitivity over traditional iodine-based agents while using the same X-ray dose.

Magnetic field hyperthermia relies on the intra-tumoural delivery of magnetic nanoparticles by interstitial injection, followed by their heating on exposure to a remotely-applied alternating magnetic field (AMF). This offers a potential sole or adjuvant route to treating drug-resistant tumours for which no alternatives are currently available. However, two challenges in nanoparticle delivery currently hinder the effective clinical translation of this technology: obtaining enough magnetic material within the tumour to enable sufficient heating; and doing this accurately to limit or avoid damage to surrounding healthy tissue.

Two-directional beam-tracking (2DBT) is a method for phase-contrast imaging and tomography that uses an intensity modulator to structure the X-ray beam into an array of independent circular beamlets that are resolved by a high-resolution detector. It features isotropic spatial resolution, provides two-dimensional phase sensitivity, and enables the three-dimensional reconstructions of the refractive index decrement, δ, and the attenuation coefficient, μ. In this work, the angular sensitivity and the spatial resolution of 2DBT images in a synchrotron-based implementation is reported.
