Abstract:
COVID-19 is a global healthcare pandemic that is now growing through nations across the world. The role of radiology is crucial, and a variety of guidelines have been published regarding the role of imaging. These aim to protect healthcare workers (HCWs) and the general public from exposure, while preserving critical radiology operations and conserving personal protective equipment (PPE) and other critical care resources during the COVID-19 pandemic. Fleischner Society published guidelines on indications of imaging various settings. These guidelines take into account resource availability, pre-test probability, degree of symptoms and risk factors, which is crucial for decision-making regarding need and indications of imaging. Mitigating steps and alternative approaches should be considered to provide the best care for patients while protecting all HCWs. Owing to overlap of COVID-19 imaging findings with other pathologies, standardized reporting acquires importance for risk assessment and effective communication of suspicious findings. RSNA followed by Dutch Radiological Society (NVvR) have published guidelines on standardized CT reporting for COVID-19, which show excellent inter-observer variability. Standardized reporting can provide guidance and confidence to radiologists as well as increased clarity to physicians through reduced reporting variability. The article discusses the published recommendations and aims to make radiologists aware of the protocols and guidelines that need to be followed in this ongoing public health crisis for effective patient care while protecting HCWs and conserving resources.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
