The acquisition of volumetric post-contrast MRI has clear advantages in the interpretation of neuro-oncology studies but has yet to find its way into routine clinical practice beyond planning scans for surgery and radiotherapy. This commentary briefly highlights the benefits of these techniques whilst dispelling some of the perceived disadvantages.

Enhanced external counterpulsation (EECP) is widely utilized in rehabilitating patients after percutaneous coronary intervention (PCI) and has demonstrated efficacy in promoting cardiovascular function recovery. Although the precise mechanisms of the therapeutic effects remain elusive, it is widely postulated that the improvement of biomechanical environment induced by EECP plays a critical role. This study aimed to unravel the underlying mechanism through a numerical investigation of the in-stent biomechanical environment during EECP using an advanced multi-dimensional 0/1D-3D coupled model.

Purpose: Staging of non-small cell lung cancer (NSCLC) is commonly based on [F]FDG PET/CT, in particular to exclude distant metastases and guide local therapy approaches like resection and radiotherapy. Although it is hoped that PET/CT will increase the value of primary staging compared to conventional imaging, it is generally limited to the characterization of TNM. The first aim of this study was to evaluate the PET parameter metabolic tumor volume (MTV) above liver background uptake as a prognostic marker in lung cancer.

Aims: To evaluate outcomes and toxicity after intensity-modulated radiation therapy given as step-and-shoot (SS) or volumetric modulated arc therapy (VMAT) for patients with locally advanced esophageal cancer treated with trimodality therapy (i.e. neoadjuvant concurrent chemoradiation therapy followed by surgery).

Purpose: Moderate hypofractionation (MHF) offers logistical and financial advantages, and has become standard in Western countries but not yet in Africa. This study assessed GI and genitourinary (GU) acute toxicity in Rwandan men undergoing MHF (20 × 3 Gy) treatment.
Materials And Methods: Since 2021, patients with prostate cancer at the Rwanda Cancer Centre have been informed about the study on MHF treatment and could participate by signing an informed consent.

Objective: To investigate significant differences in selected radiomic parameters when classifying periapical lesions based on volumetric size, cortical expansion, erosion, and shape using Cone Beam Computed Tomography (CBCT).
Methods: A retrospective analytical and comparative study was conducted on 100 small field of view (FOV) 50×50 mm CBCT scans collected between the years 2018 and 2023. The study involved qualitative classification of periapical lesions, followed by segmentation and extraction of radiomic parameters.
