The erect anteroposterior chest view is the alternative to the PA view when the patient is too unwell to tolerate standing or leaving the bed 1. The AP view examines the lungs, bony thoracic cavity mediastinum and great vessels. This particular chest X-ray is often used frequently to aid diagnos...
The AP lordotic chest radiograph (or AP axial chest radiograph) demonstrates areas of the lung apices that appear obscured on the PA/AP chest radiographic views. It is often used to evaluate suspicious areas within the lung apices that appeared obscured by overlying soft tissue, upper ribs or th...
An expiratory chest radiograph can be taken in either a PA or AP projection, and can also be taken with a mobile/portable unit. They are used to help detect small pneumothoraces (although sensitivity is not increased over inspiratory chest radiographs 1), and to assess for inhaled foreign bodies...
The lateral chest view is part of a common radiological investigation of the chest in the emergency department 1. The lateral chest view examines the lungs, bony thoracic cavity, mediastinum and great vessels.
Although the PA chest view is the primary view in chest imaging, the lateral radiogr...
Posteroanterior (PA) chest view is the most common radiological investigation in the emergency department 1. The PA view examines the lungs, bony thoracic cavity, mediastinum and great vessels. The chest X-ray is frequently used to aid diagnosis of acute and chronic conditions.
The supine anteroposterior chest view is the alternative to the PA view and the AP erect view when the patient is generally too unwell to tolerate standing leaving the bed, or sitting 1. The supine view examines the lungs, bony thoracic cavity mediastinum and great vessels.
This particular ches...
The chest radiograph (CXR) is the most ubiquitous radiological investigation.
The chest radiograph is performed for a broad content of indications, including but not limited to 1-4:
suspected pulmonary embolism
CT polytrauma/multitrauma (also called trauma CT) is an increasingly used test in the patient with multiple injuries sustained after significant trauma.
There is some evidence that trauma patients who undergo whole body CT (WBCT) / panscan have better survival than patients who undergo selectiv...
Lung hyperinflation is a common feature of patients with chronic obstructive pulmonary disease (COPD). It is also linked to ageing and other chronic diseases that cause airflow obstruction.
The airflow limitation during expiration is produced by two factors:
destruction of the lung ...
This article lists examples of normal imaging of the chest and surrounding structures, divided by modality.

The Rapid ultrasound in shock (RUSH) protocol is a structured point-of-care ultrasound examination performed at the time of presentation of a shocked patient. It is a more detailed and longer exam than the FAST scan, with the aim to differentiate between hypovolemic, cardiogenic, obstructive and...
The lateral sternum view a radiographic investigation of the entire length of the sternum in profile. The view is used to query fractures or infection 1.
patient is erect with the left or right side of the thorax adjacent to the image receptor
patient's hands are behind their...
Triple-rule-out CT (TRO CT) angiography may be ordered in the setting of acute chest pain to examine the thoracic aorta and the coronary and pulmonary arteries. The protocol helps exclude life-threatening causes of acute chest pain, especially if atypical, or if alternative causes to acute coron...
V/Q (ventilation/perfusion) scan is a scintigraphic examination of the lung that evaluates pulmonary vasculature perfusion and segmental bronchoalveolar tree ventilation.

Xenon-127 is a radiopharmaceutical principally used when a performing VQ scan. It is an not widely used alternative to xenon-133 with the main advantage being a higher proton energy allowing for post perfusion scanning.
photon energy: 203 KeV
physical half life: 36.3 days
