Background: Infections of the liver are common and can continue a long time. Furthermore, the fatality rate associated with chronic liver illnesses remains high, despite continuing development of novel diagnostic and treatment processes. As a result, significant attempts to improve imaging techniques have been made, notably in this decade. The morphology, circulation, metabolism, parenchymal texture, fibrosis, and/or tumour viability of the liver can all be investigated using contemporary imaging methods. Some of the novel imaging techniques and procedures that have made it possible to monitor liver function include magnetic resonance perfusion, magnetic resonance elastography, and dual-energy computed tomography (CT). Objective:The study aimed to highlight on improved imaging techniques and advanced interventional radiology (IR) technologies, new multimodality treatments for liver illnesses have been developed. Methods: PubMed and Google scholar were searched using the following keywords: Liver diseases, CT, MRI and liver treatments. The authors also screened references from the relevant literature, including all the identified studies and reviews, only the most recent or complete study was included, and in peer-reviewed articles between February 2010 and July 2021.Conclusion: Finally, this special review reviewed recent breakthroughs in both diagnostic and interventional radiology, providing us with useful perspectives in this rapidly evolving discipline.

Background: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. Radiology, MRI, CT, and PET scans play an important role in the evaluation, diagnosis, and triage of patients with TBI. Recent studies suggest that it will also help predict patients' outcomes.Objective: This study aimed to investigate the benefits from using MRI, CT, and PET scans to diagnose brain injuries or diseases, radiologically. Methods: PubMed, Google scholar and Science direct were searched using the following keywords: Brain injury, brain disease, MRI, CT and PET scans. The authors also screened references from the relevant literature, including all the identified studies and reviews, only the most recent or complete study was included between December 2007 and January 2022. Documents in a language apart from English have been excluded as sources for interpretation. Papers apart from main scientific studies had been excluded (documents unavailable as total written text, conversation, conference abstract papers and dissertations). Conclusion: Primary and metastatic brain tumours are frequently observed in neuroimaging practice. Because of the wide number of treatment options currently available to treat these tumours, post-treatment imaging interpretation has proven to be challenging. Understanding post-treatment imaging methods, treatment response criteria, and common treatment-related issues will help you tackle this tough topic more easily.

Background: Interventional radiology guided by computed tomography (CT) uses minimally invasive techniques to perform medical diagnostics and treatments. Because it is widely available and can be conducted using a wide range of equipment, CT is frequently utilized for interventional image guiding. Objective: This article highlighted for CT-guided interventional radiology procedures, areas and technique. Methods: Google scholar and PubMed were searched using the following keywords: CT-guided interventional radiology and CT scan. The authors also screened references from the relevant literature including all the identified studies and reviews, only the most recent or complete study was included, between June 2002 and December 2020. Conclusion:The use of CT-guided interventions radiology may offer a number of advantages. A high accuracy of instrument placement avoids the damage of vulnerable structures adjacent to the target and high accuracy to perform diagnostic and therapeutic medical procedures. In addition, could reduce the need for verification scans or CT fluoroscopy resulting in less radiation exposure.
