Chest X-rayRead the Chest X-ray article » 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 against 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 differences in their composition (and, therefore, varying degrees of penetration of the X-ray beam), the lungs, heart, aorta, and bones of the chest each can be distinctly visualized on the chest X-ray. The X-ray film records these differences to produce an image of body tissue structures and these are shadows seen on the X-ray. The white shadows on chest X-ray represent more dense or solid tissues, such as bone or heart, and the darker shadows on the chest 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 requested to use an X-ray gown, and extra metallic objects such as jewelry are removed from the chest and/or neck areas. 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 ... Recommended Reading Related to Chest X-rayWhat is microsporidiosis? What causes the disease?Microsporidiosis is a disease caused by infection with microscopic organisms called microsporidia. Microsporidia are eukaryotic parasites that must live within other host cells in which they can produce infective spores. These spores cause microsporidiosis, a disease which is primarily seen in individuals infected with human immunodeficiency virus (HIV). Microsporidiosis can cause infection of the intestine, lung, kidney, brain, sinuses, muscles, and eyes. Although there are over 1,200 species of microsporidia, the most prevalent pathogens (disease-causing agents) in humans include Enterocytozoon bieneusi, Encephalitozoon cuniculi, and Encephalitozoon intestinalis. How are microsporidia transmitted?Microsporidia spores are released from the stool and urine of infected animals. A number of animals, including insects, birds, and mammals, can serve a...

Low Blood Pressure
- Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
-
Congestive Heart Failure
- Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs. A poor blood supply resulting from congestive heart failure may cause the body's organ systems to fail, leading to a weakened heart muscle and fluid accumulation in the lungs and body tissue. There are many diseases that can impair pumping efficiency and symptoms of congestive heart failure including fatigue, diminished exercise capacity, shortness of breath, and swelling. Treatments include lifestyle modifications, medications, heart transplant, and therapy.
-
Lung Cancer
- Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small cell or non-small cell cancers.
-
Ovarian Cancer
- There are many types of ovarian cancer, epithelial carcinoma is the most common. Women with a family history of ovarian cancer have an increased risk of developing the disease. Some ovarian cancer symptoms include abdominal pain, nausea, diarrhea, constipation, and abnormal vaginal bleeding, however, they usually do not present until the disease has progressed. Early diagnosis is important for successful treatment.

-
Melanoma
- Melanoma is a type of skin cancer which begins in skin cells called melanocytes and affects more than 53,600 people in the United States each year. These melanocytes can grow together to form benign moles which, after a change in size, shape, or color can be a sign of melanoma. Caused by sun exposure, early detection becomes extremely important to avoid a spread to other areas of the body. Diagnosis is confirmed through a biopsy of the abnormal skin and treatment depends on the extent and characteristics of the patient.
-
Stomach Cancer
- Though the cause of stomach cancer is unknown, risk factors for stomach cancer include diet, H. pylori infection, smoking age, gastritis, stomach surgery, family history, and pernicious anemia. Symptoms include stomach discomfort, feeling full after a small meal, nausea and vomiting, and weight loss. Treatment depends upon staging and may involve surgery, radiation therapy, or chemotherapy.
