293.Aspiration, barium gone wild

每天朗读一段医学影像学英语文章

Frontal radiograph of the lung bases demonstrates high density material outlining the tracheobronchial tree (solid white arrows). The material is barium that was aspirated into the lung during an upper gastrointestinal series. Barium is inert and did not cause any additional symptoms that the patient wasn't already experiencing from aspirating his own secretions. It will take some time, but most of this barium will be reabsorbed, most likely leaving only a small amount remaining.

Notes

1. tracheobronchial tree/ˌtreɪkɪəʊ'brɒŋkɪəl/支气管树

2. inert /ɪ'nɝt/adj.惰性的

3. secretion /sɪ'kriʃən/n.分泌物

Recognizing Gastrointestinal, Hepatic, and Urinary Tract Abnormalities

In this chapter, you’ll learn how to recognize some of the most common abnormalities of the gastrointestinal (GI) tract from the esophagus to the rectum. We’ll also discuss selected hepatic abnormalities. Chapter 19 on ultrasound will describe some of the more common biliary and pelvic abnormalities.

CT, ultrasound, and MRI have essentially replaced conventional radiography and, in some instances, barium studies for the evaluation of the GI tract and the visceral abdominal organs.

Barium Studies of the Gastrointestinal Tract

During the performance of barium studies, fluoroscopic spot films and overhead films are usually obtained by the radiologist and radiologic technologist in several projections for whatever part of the GI tract is being studied, depending on the nature of the abnormality and the mobility of the patient.

As you go through this chapter, you will probably want to refer to the two tables in this chapter, one on terminology used in describing studies of the GI tract (Table 18-1) and the other on basic principles in GI radiology (Table 18-2), both of which will prove helpful in understanding the terms and concepts used here.
