Lateral chest X-ray Let’s take a second to try to understand why it is that the heart appears bigger than normal on AP studies. Imagine you are holding a flashlight, pointing it so that the circle of light appears against a white wall a foot away from you. Now imagine holding a pen...
Measuring across a normal heart is less than 50% of the greatest diameter of the ribcage measured from the inner portion of each rib. Any larger, and there may be cardiac pathology. C指心脏轮廓和大小。这是心脏的轮廓,这...
Then to understand the basic concept of X-ray radiation, we again require the knowledgeof physics to know how electrons are accelerated between electrodes which are placed in a vacuum in an X-ray tube. And how these accelerated electrons finally produce radiation in the form of X-rays. Anothe...

What happens after the X-ray procedure? There are no side effects or after-effects of a regular X-ray and you should be able to return to your normal daily activities immediately. If you had an X-ray with contrast, there may be some temporary side effects. Barium may cause yourstoolto...
A structured approach to chest X-ray interpretation with examples of pathology you'll be expected to recognise in an OSCE.
they may enable the asthmatic diver to descend easily but are less effective towards the end of the dive and also when a rapid emergency ascend may be required. More importantly, bronchodilator medication has a potential of causing an arrhythmic effect on the heart and is a potentially hazardou...
