If the radiographic image is of diagnostic quality, you are able to perceive objects/structures because of their atomic composition and the state of the matter in those objects/structures.The terms used to compare objects of different darkness or whiteness are radiolucent (dark, less opaque) and radiopaque (white, more opaque).

Initially we have to review all the normal structures on a thoracic radiograph before we can begin to discuss pathology. So a review....There are three main normal structures in the lungs: the interstitium, airways, and vessels. The interstitium is the supporting structure of the lungs.

Let's begin with the upper urinary tract – the kidneys and ureters. Knowing normal anatomy is of course initially necessary to perform an adequate ultrasound examination. You should always scan in two planes (sagittal and transverse). The right kidney is harder to visualize as it is located at the level of T13 and is located in the caudate fossa of the liver.

Sonographic evaluation of the gastrointestinal tract is a routine part of the diagnostic investigation of gastrointestinal disorders. Improved visualization of the GI tract has been achieved due to technologic advances in both ultrasound machines and with the development of higher frequency transducers.

Radiology is like standing on the outside of the building; it allows you to see the size, shape and contour of the building; ultrasound allows you to look into each room in the building i.e. the liver room, the gallbladder room, the pancreas room, the kidney room, the urinary bladder room etc.

Osteochondritis dissecans (osteochondrosis dissecans, OC, OCD) is the most common of the developmental orthopedic diseases and is caused by a sub-condral ossification defect that results in increased thickness of soft articular cartilage, thus decreased nutrient and oxygen availability (from articular fluid) and secondary mechanical failure resulting in a concave bony defect and cartilage flap formation.

The survey ultrasound study is primarily used to assess soft tissue composition and in some cases function (echocardiogram) as well as guide you in biopsying "soft tissue" lesions. It has limited value in assessing bone-primarily restricted to the bone surface and it has no value in evaluating gas other than letting you know gas is present.
