Objective: Obesity is a very common health problem and is considered a global non-communicable disease by the World Health Organization (WHO). Modern-day obesity is mainly due to physical inactivity, a high-calorie diet, and a sedentary lifestyle. It is associated with a multitude of commodities, such as diabetes type II, cardiovascular disease, hypertension, and even cancer. Due to this, obese patients are more likely to present for health assessment and are more likely to require imaging. The size of these patients brings diagnostic challenges involving gantry size, image quality, and radiation exposure. This review article compiles all the challenges and new techniques to overcome them during the imaging of the obese. Key findings: There are many challenges to imaging the obese, as mentioned. Each modality also has its own specific set of challenges. There have been efforts to overcome these shortcomings, and many manufacturers now produce machines with higher weight load capacity and many other features to improve imaging of the obese, as mentioned in this article. Conclusion: Obese patients face unique challenges in medical imaging and intervention. Over the last few years, medical manufacturers, radiographers, and radiologists have recognized these issues and come up with innovative techniques to overcome these challenges. Implications for practice: Technical challenges of imaging obese patients need to be known and addressed, as mentioned in this paper.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is defined as the virus causing the present coronavirus disease outbreak (COVID-19) that has been initially discovered in Wuhan, China after complaints of severe pneumonia. The impact of vitamin D on complications and treatment of COVID-19, as well as its potential role in lowering the incidence of COVID-19, has been the subject of much investigation. The correlation between COVID-19 infections and vitamin D will be demonstrated in the presented work.
