In the United States, chest radiographs are performed on patients with positive tuberculin skin test (TST) results. It is not known whether, in addition to a single posteroanterior radiograph, a lateral chest radiograph is clinically indicated or cost-effective. We sought to determine the utility of the lateral chest radiograph in evaluating TST-positive adults.
Cross-sectional study.
Tertiary-care hospital.
Adults with positive TST results.
Findings on posteroanterior radiographs alone were compared to posteroanterior and lateral chest radiographs.
In 2 of 535 cases (0.4%), lateral chest radiographs revealed a calcified granuloma not visible on posteroanterior radiographs. This finding did not alter patient management. In all other cases, lateral radiographs only confirmed findings seen on posteroanterior chest radiographs.
Treatment altering findings were always visible on posteroanterior radiographs alone. These results suggest that lateral chest radiographs are not useful in evaluating adults with positive TST results.
在美国，结核菌素皮肤试验（TST）结果呈阳性的患者会接受胸部X光检查。目前尚不清楚，除了一张后前位X光片外，侧位胸部X光片在临床上是否必要或具有成本效益。我们试图确定侧位胸部X光片在评估TST结果呈阳性的成年人中的作用。
横断面研究。
三级医疗医院。
TST结果呈阳性的成年人。
将仅后前位X光片的检查结果与后前位和侧位胸部X光片的检查结果进行比较。
在535例病例中的2例（0.4%）中，侧位胸部X光片显示出后前位X光片上不可见的钙化肉芽肿。这一发现并未改变患者的治疗方案。在所有其他病例中，侧位X光片仅证实了后前位胸部X光片上的所见。
改变治疗方案的检查结果在后前位X光片上总是可见的。这些结果表明，侧位胸部X光片在评估TST结果呈阳性的成年人时并无用处。
