X Ray Of Sinuses
Sinuses are air filled spaces in the head that have several proposed functions: 1. They serve as shock absorbers in cases of head trauma 2. Lighten the skull 3. Humidify and filter the air while also producing mucus 4. Play a role in vocal resonance. The head contains 4 paired sinus cavities: maxillaries (cheek) under the eyes, ethmoids(between the eyes), frontals (above ...Read more

What is better CT scan or mir to further diagnose right superior mediastinum widening in the chest x ray?
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

Can a chest CT scan rule out lung cancer? I have pain in shoulder/clavicle. X ray and CT clear. Pain persists along with sore sternum/throat.
Yes and no: The X-ray will show a mass on the bony spine , at times haze on the soft tissue on the spine and lesions eroding the spine. Al of these masses that can be seen on X-rays can be benign or malignant. Thus the X-ray will show the mass but can not prove it is cancer without a biopsy ...Read more
Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read moreSee 1 more doctor answer
Do chest CT scans w/contrast include evaluation of the clavicle and shoulder? What about chest xrays?
Yes&No: Some of the clavicle can be seen. The shoulder, not too much. CXR does see both, but is a 2Dimensional image and therefore don't see other views of the shoulder. ...Read more
