What is a chest X-ray?
A chest X-ray is a radiology test that involves exposing the chest briefly to radiation to produce an image of the chest and the internal organs of the chest. An X-ray film is positioned beside the body opposite the camera, which sends out a very small dose of a radiation beam. As the radiation penetrates the body, it is absorbed in varying amounts by different body tissues depending on the tissue’s composition of air, water, blood, bone, or muscle. Bones, for example, absorb much of the X-ray radiation while lung tissue (which is filled with mostly air) absorbs very little, allowing most of the X-ray beam to pass through the lung.
What is a shadow on a chest X-ray?
Due to the disparities in their work which varies the degrees of the penetration of the x-ray beam;, the lungs, heart, aorta, and bones of the chest each can be clearly visualized on the chest X-ray. The X-ray motion picture records these differences to create an image of body tissue structures and these are shadows observed on the X-ray. The white shadows on chest X-ray signify more dense or solid tissues, such as bone or heart, and the darker shadows on the upper body X-ray represent air filled tissues, such as lungs.

How is the chest X-ray procedure performed?
Patients obtaining a chest X-ray will often be demanded to use an X-ray gown, and extra metallic objects such as jewellery are removed from the chest and/or neck areas to provide a safe procedure and may cause interference to the procedure if worn. These objects can block X-ray penetration, making the result less accurate. Patients may be asked to take a deep breath and hold it during the chest X-ray in order to inflate the lungs to their maximum, which increases the visibility of different tissues within the chest. The chest X-ray procedure often involves a view from the back to the front of the body as well as a view from the side. The view from the side is called a lateral chest X-ray. Occasionally, different angles are added in order for the radiologist to interpret certain specific areas of the chest. The radiology technologist or technician is a trained, certified assistant to the radiologist who will help the patient during the X-ray and actually perform the X-ray test procedure. After the chest X-ray is taken and recorded on the X-ray film, the film is placed into a developing machine, and this picture (which is essentially a photographic negative) is examined and interpreted by the radiologist.
What are the risks of a chest X-ray?
Chest X-rays picture the patient for a short time so that a minimum amount of radiation is needed in the matter as any radiation exposure has some risk to the tissues of the body. The radiation exposure in a chest X-ray is minimized by the type of X-ray high-speed film, which does not need as much radiation exposure as in the past.
What can be seen on normal chest X-ray?
Normal chest X-ray shows normal size and shape of the chest wall and the main structures in the chest. The white shadows on the chest X-ray signify solid structures and fluids such as, bone of the rib cage, vertebrae, heart, aorta, and bones of the shoulders. The dark background on the chest X-rays represent air filled lungs. These lung fields are seen on either side of the heart and the vertebrae located in the centre of the film.

What are the two Endoscopes? An endoscopy is when a doctor uses an endoscope (a thin, very long and flexible instrument less than 1/2 inch in diameter) to observe the inner parts of the digestive system. Usually, it is inserted in upper endoscopies, in which endoscope is inserted into the mouth and the upper part of the digestive system is examined. Also, it can be inserted in lower endoscopies, the instrument is passed into the anus and the colon is studied.
What are they used for? Endoscopies are used to recognize the possible causes of such symptoms as nausea, pain, bloating or vomiting, as well as identify or rule out ulcers, inflammation and even tumours. The endoscope can also be used to take tiny tissue samples, eliminate growth, stretch areas and treat internal bleeding.
Upper Endoscopy Procedure You must have an empty stomach before an endoscopy, so you should not eat eight hours before the procedure. You will be given a calming through an IV into your vein and a pain reliever, as well. Also, it will be important to spray the back of your throat as it will make sure that it is numb and won’t cause the person to gulp, this process in important whilst taking on the upper Endoscopy .
Then, a mouthpiece will be put in your mouth, and you will be asked to lie on your left side. A specialist will insert the endoscope through the mouthpiece and down your oesophagus, then into your stomach. You will be able to breathe just fine and will remain awake during the procedure, which will take about 20 minutes which is a very short time and a big procedure.
Lower Endoscopy Procedure In a lower endoscopy, the patient will need to take an enema the day before the procedure, which means the patient should not go to work on that day or the day of the procedure. The doctor will probably also give the patient some dietary restrictions to follow two days before the procedure.

Directly before the procedure, the patient will be given a sedative and often a pain reliever through an IV. The patient will lie down, and the endoscope is inserted through the anus and into the colon, where the inspection will take place. The examination usually takes around 30 minutes which is a short period for such an important procedure. After that, the patient will be told to take it easy for a few hours, although she can eat and drink right away.
