Can You See Lung Cancer On An X Ray
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

It depends on they specific type of bone tumor, the involved bone and the size of the tumor. Sometimes special scans such as a ct or MRI scan are needed to detect a bone tumor. ...Read moreSee 1 more doctor answer
See answer: Ovarian cysts are filled with fluid and are soft tissue density – and are not seen routinely on regular xrays unless they contain calcification (which is unusual). Ultrasound (or possibly mri) of the pelvis is the preferred imaging modality although cysts can be identified with ct. ...Read moreSee 1 more doctor answer
My doctor says small cell lung cancer (sclc) can be seen on chest x-ray. Is this true? Or would you need a ct-scan?
Yes: Chest xray looks at the lung tissue superimposed on a the chest wall tissue including the ribs and all the muscles and thus can miss subtle findings. In addition, lung infection can be subtle, with presentation as a small focus of infection or a rather very faint infection area that can be very difficult to detect with xray alone. A ct study may be useful if necessary. ...Read moreSee 1 more doctor answer
How can you tell if you have a cavity on a x ray, and can dental x rays cause shadows on a tooth, if it is not done right?
Looks dark: Viewing dental x-rays, we look for darkness on film meaning less dense tooth. In between teeth, we look for a break in the enamel shell. We also look for other abnormalities on these films including bone loss, radiolucencies in jaw bone, impacted teeth, etc. It would be difficult to alter specific locations on films. The film would be too dark or light. So, no. ...Read moreSee 1 more doctor answer
Usually misses it: You asked about this before. A chest xray almost always will miss Kaposi sarcoma, which doesn't usually cause lung or chest problems.

Yes if greatly enlar: An enlarged heart can be seen on X-ray or CT scan especially if it is greatly enlarged. However, the cause for the enlargement is usually not apparent by those means. An echocardiogram (ultrasound) usually does a better job. sometimes more specialized tests are needed. However, if this is the 1st time that an enlarged heart was detected, it is best to get it confirmed & identify the cause. GL & TY ...Read more
Clinical diagnosis..: An air embolism is usually diagnosed on clinical grounds and it cannot be visualized on an EKG or chest xray. Sometimes, if an echocardiogram is done immediately, and if there is enough air present, it can be seen with this ultrasound test. This diagnosis is usually made when there are symptoms of it in the right clinical scenario. ...Read more
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
