Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs. It is typically defined as an area of hazy opacification (x-ray) or increased attenuation (CT) due to air displacement by fluid, airway collapse, fibrosis , or a neoplastic process . [ 1 ]
AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film").
Bagassosis was first reported in India by Ganguly and Pal in 1955, in a cardboard manufacturing plant near Kolkata. India has a large cane sugar industry.The sugarcane fibre which, until recently, went to waste, is now utilised in the manufacture of cardboard, paper and rayon.
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
In modern medicine, radiodense substances are those that will not allow X-rays or similar radiation to pass. Radiographic imaging has been revolutionized by radiodense contrast media , which can be passed through the bloodstream, the gastrointestinal tract , or into the cerebral spinal fluid and utilized to highlight CT scan or X-ray images.
But, before they made the trek to the foreign land, they checked to see if a hedgehog saw its shadow, not a groundhog. Due to a lack of hedgehogs in America, the settlers began using another ...
Tuberculosis creates cavities visible in x-rays like this one in the patient's right upper lobe. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. [citation needed]
