In this paper we shortly review the influence of COVID-19 on radiotherapy. We describe some of the possible solutions for telehealth in target delineation - a crucial part of high-quality radiotherapy, which often requires multidisciplinary effort, hands-on corporation, and high-quality multimodal imaging. Hereafter, our own technical solution will be presented as a case.Chronic lymphocytic leukaemia (CLL) is the most common leukaemia in adults. It is a malignancy of CD5 B-cells characterised by small, mature-appearing lymphocytes accumulating in the blood, bone marrow, and lymphoid tissues. Richer transformation (RT) is an important adverse complication. Detection of RT is critical to allow initiation of appropriate therapy. CLL staging and response evaluation is complicated and nuanced. From our extensive tertiary centre experience of several hundred CLL cases over the last decade, we detail key computed tomography (CT) and positron-emission tomography (PET) imaging features of the natural history of CLL. The authors present an original imaging-based patient-management paradigm for the investigation of potential RT, which will inform global practice. Potential applications of whole-body diffusion weighted imaging, novel PET radiotracers, minimal residual disease, and ct-DNA are addressed.We aimed to investigate the relationship of modified body mass index (mBMI), the product of BMI and serum albumin, with survival after transcatheter (TAVI) and surgical aortic valve implantation (SAVI). Frailty is associated with poor outcomes after TAVI and SAVI for severe aortic stenosis (AS). However, clinical frailty is not routinely measured in clinical practice due to the cumbersome nature of its assessment. Modified BMI is an easily measurable surrogate for clinical frailty that is associated with survival in elderly cohorts w
