Appropriateness of imaging modality choice by doctors at the Kenyatta National Hospital's Accident and Emergency Department.

Background: Clinical imaging guidelines assist doctors in selecting the most appropriate radiological investigation(s) according to the patient's clinical presentation and also help to avoid unnecessary radiation exposure.

Objectives: This study aimed to determine the appropriateness of choice of imaging procedures requested by the doctors in the Accident and Emergency Department (A&E) of Kenyatta National Hospital (KNH).

Method: Request forms sent to the KNH Radiology Department from the A&E Department from 01 July 2019 to 31 October 2019 were captured digitally.

Clinical Application of Magnetic Resonance Spectroscopy in Diagnosis of Intracranial Mass Lesions.

Introduction: Conventional MR imaging provides highly detailed anatomic information with unrivalled soft tissue contrast making it the mainstay in the diagnosis of suspected brain lesions. Despite this, MRI alone at times cannot answer the diagnostic questions in quite a few patients. Proton MR Spectroscopy (H-MRS) provides information on the metabolic composition within an area under interrogation.

Novel multi-linear quantitative brain volume formula for manual radiological evaluation of brain atrophy.

Objectives: The brain atrophy commonly occurs in elderly and in some childhood conditions making the techniques for quantifying brain volume needful. Since the automated quantitative methods of brain volume assessment have limited availability in developing countries, it was the purpose of this study to design and test an alternative formula that is applicable to all healthcare levels.

Methods: The multi-linear diagonal brain fraction formula (DBF) was designed from dimensions of brain relative to skull and ventricles.

Radiology practice in sub-Saharan Africa during the COVID-19 outbreak: points to consider.

COVID-19 is a rapidly growing pandemic that has grown from a few cases in Wuhan, China to millions of infections and hundreds of thousands of deaths worldwide within a few months. Sub-Saharan Africa is not spared. Radiology has a key role to play in the diagnosis and management of COVID-19 as literature from Wuhan and Italy demonstrates.

Knowledge and practices of cardiopulmonary arrest and anaphylactic reactions in the radiology department.

Background: Emergencies in the radiology department may arise in critically ill patients who are brought to the department for imaging, interventional procedures or as a result of adverse reactions to contrast media used for imaging. Adverse reactions to contrast media range from minor to severe life-threatening effects and initial, prompt management decreases complications. Radiology staff must possess knowledge of the management of anaphylactic or anaphylactoid contrast reactions and cardiopulmonary arrest (CPA) as they are likely to be the first responders.
