Image quality can also be affected by the direction of the central x-ray beam. They include the dorsoplantar, lateral, and medial oblique foot views and the anteroposterior, mortise, and lateral ankle views.

Test adequacy criteria is thus a key to show how the test suites are going to be filled in. Use of comparison views should decrease as the practitioner’s level of experience increases. This is especially true in the chest, which has considerable depth. In this section of the Criteria Cognitive Aptitude Test, you’ll be presented with number series and word problems and the questions may cover fractions, decimals, multiplication and division, and basic algebra. Because the distribution of radiographic findings and patterns of joint involvement are important aspects for the evaluation of joint disease, bilateral dorsoplantar and lateral views are advocated. ANSWER: ANSWER. Comparison views of the opposite, asymptomatic extremity may be useful when a questionable lesion or finding is present in the affected extremity. For example, when evaluating the first metatarsophalangeal joint for degenerative joint disease, only dorsoplantar and lateral views are necessary to make the diagnosis. An oblique view ordinarily does not offer any additional information in the diagnosis of osteoarthritis unless the physician is looking for a more specific condition or lesion, such as a loose osseous body. This website and its content is subject to our Terms and Radiography Image Analysis Objective Question with Answer, Lesson Plan for Radiography Image Interpretation, New BTEC National Applied Science Unit 3 revision matts. Preview. Abnormal. Comparison views of the pediatric foot or ankle may actually be misleading more often than they are beneficial. A method is presented that simplifies the process by which views are selected. BOX 10-1 Potential Indications for Radiographic Study of the Foot or Ankle (MINTCAP), Metabolic, endocrine, nutritional disorders. Selecting positioning techniques for a foot or ankle study should not be performed as a routine. Of course, conditions that can demonstrate generalized radiographic findings, such as inflammatory joint disease, require examination of other regions and/or extremities. The outermost aspect or margin of a tubular bone, for example, seen in a two-dimensional radiograph represents the three-dimensional anatomic surface that is tangent to the primary x-ray beam. Bilateral studies have also been advocated for the pediatric radiographic study, especially for epiphyseal injuries.1 However, irregular ossification, multiple ossification centers, and accessory ossification centers are frequently encountered as variations of normal development; their differentiation from abnormality may be impossible, even with comparison views of the opposite extremity. Some practitioners, however, habitually obtain views of both extremities for every radiographic study performed. Radiographs are routinely ordered by many for patients presenting with a history of trauma, with the intent of providing medicolegal documentation. Before studying the following paradigm, it is important to understand the concept of marginal (or tangential) surfaces. Potential indications for radiographic study of the foot or ankle are listed in Box 10-1. The message of the term is simple - adequacy criteria defines or sets a limit or boundary which is sufficient enough to stop testing. One example is the routine bilateral radiographic foot or ankle study. 3) shell intersections (verticle to horizontal) 4) nozzles. The average raw score on this test is 24.

To become familiar with the multiple superimposed shadows in the midfoot, rearfoot, and ankle regions, one must study these areas carefully and correlate them to the gross anatomic specimen routinely, not just when searching for a specific pathology. 2) shell horizontal . It is not uncommon for certain practices or procedures to continue for decades without being questioned. Will the outcome of the study affect the treatment instituted?
