Lateral soft tissue neck X-rays: are they useful in management of upper aero-digestive tract foreign bodies?EBSCO_AspJournal of Laryngology & Otology
The usual X-ray picture does not provide depth information. The image represents the total attenuation as the X-ray beam passes through the object in its path. For example, a conventional X-ray of the lung may reveal the existence of a tumor, but it will not show how deep in the lung...
Irrespective of the difference between T1- and T2-weighted images, proton density weighing is also used to get contrast between soft tissue images. The major difference between MRI and other transmission-based techniques, such as CT and X-ray, is that MRI is based on signals sent by the ...
The soft tissues in the body (like blood, skin, fat, and muscle) allow most of the X-ray to pass through and appear dark gray on the film. A bone or a tumor, which is denser than soft tissue, allows few of the X-rays to pass through and appearswhiteon the X-ray. Where does ...

The chest radiograph confirmed extensive emphysema; and a computed tomography scan diagnosed pneumothorax on both sides invisible on conventional radiography with gas in the soft tissue of the neck, chest, and abdominal wall. Pneumothorax may not be detectable in standard chest x-ray, may cause ...
Methods of correcting for tissue inhomogeneities which consider only changes in the fluence are of limited usefulness for 10-MV x rays. Although there is normally transient electronic equilibrium on the central axis beyond the depth of maximum buildup in soft tissue, when the beam enters a low-...
Geometric structure of the femoral neck measured using dual-energy X-ray absorptiometry An algorithm was developed to estimate the strength of the femoral neck from data generated by the dual-energy x-ray absorptiometry (DXA). This algorithm c... T Yoshikawa,CH Turner,M Peacock,... - 《Journ...
ray attenuation. Lung tissue is distinguishable owing to the presence of air within its cavity, thus yielding significantly lower densities than the surrounding soft tissue and bone [2]. Adipose is high in fatty acids and is slightly less dense than adjacent soft tissue, which enables its ...
Introduction: soft tissue sarcomas are a subset of malignant tumors that are relatively rare and make up 1% of all malignant tumors in adulthood. Due to the rarity of these tumors, there are significant differences in quality in the diagnosis and treatme
