Right Ventricular Dimension 1. Right Ventricular Size RV dilatation often associated (although not always) with acute pressure overload. Common pathologies includes acute pulmonary embolism and RV failure. 1.1 Subjective assessment (or what the experts called “eyeballing”) View: A4C (right ventricle-focused view) Phase: end diastole (where chamber size at max)   Nothing fancy, just a simple

Pneumothorax – CXR What’s normal ? There is not much else to say here. You would expect in a normal CXR with full lungs expansion, you will see the vasculature and bronchial marking spread evenly to the edge of the chest wall bilaterally. What’s not normal ? In CXR with pneumothorax you will see a

Lobar Collapse What’s normal ? For further details on the normal CXR please see specific section here. For quick revision, in the normal CXR where both lungs are fully expanded, (because of the difference in tissue density) you should be able to see all sides border of the lungs, including the normal cardiomediastinal contour. The

Pulmonary Embolism What’s normal ? For further details on CTPA please see specific section on CTPA and CT angiogram. In summary, the contrast helps to enhance the outline of the vessels. The normal CTPA has continuous flow of hyper-attenuated contrast within the vasculature of pulmonary artery (PA) and its branches. Figure 1: CT chest without
