COVID-2019 Pneumonia: Severity and distribution of lung changes observed on the initial chest X-ray as an indicator of final outcomes.

Objectives: This study aimed to assess the correlation between the severity of the initial chest x-ray (CXR) abnormalities in patients with a confirmed diagnosis of COVID-19 and the final outcomes.

Methods: This retrospective study was conducted at the Royal Hospital, Oman between mid-March and May 2020 and included patients who had been admitted with a confirmed diagnosis of COVID-19 and had a final outcome. Serial CXRs were identified and examined for presence, extent, distribution and progression pattern of radiological abnormalities.

COVID-19 Associated Pneumonia: A review of chest radiograph and computed tomography findings.

Medical imaging, including chest radiography and computed tomography, plays a major role in the diagnosis and follow-up of patients with COVID-19 associated pneumonia. This review aims to summarise current information on this topic based on the existing literature. A search of the Google Scholar (Google LLC, Mountain View, California, USA) and MEDLINE (National Library of Medicine, Bethesda, Maryland, USA) databases was conducted for articles published until April 2020.

Pulmonary Hyalinising Granuloma: A report of two cases.

Pulmonary hyalinising granuloma (PHG) is a rare fibrosclerosing inflammatory lung condition of unknown aetiology. It is characterised by solitary or multiple pulmonary nodules that are usually found incidentally while imaging the chest for other reasons. We report two cases of histologically proven PHG diagnosed at the Royal Hospital, Muscat, Oman.

Prevalence and Spectrum of Coronary Anomalies Detected on Coronary Computed Tomography Angiography: A single centre experience in Oman.

Objectives: Coronary artery anomalies (CAAs) are uncommon congenital abnormalities with a prevalence ranging from 0.2-2%. CAAs can be asymptomatic or less commonly present with life-threatening symptoms.

A New Variant of Dual Left Anterior Descending Artery Anomaly: Type XI.

A dual left anterior descending (LAD) artery is a rare congenital anomaly which is classified into different types based on the origin, course and termination of the short and long LAD arteries. To date, 10 variants of dual LAD artery anomalies have been described. We report a 44-year-old woman who was referred to the Department of Radiology, Royal Hospital, Muscat, Oman, in 2017.
