PULMONARY EMPHYSEMA RECOGNITION BY CT SCAN

The relationship between emphysema on CT scan and lung cancer.

I commend Maldonado and colleagues 1 for their extended reanalysis of lung cancer screening data to explore the association between emphysema on CT scan and lung cancer in a recent issue of CHEST (December 2010). Attempts to validate previously published fi ndings are all too rare. The authors report the absence of a clear relationship between emphysema (quantitative or dichotomous) and the odd...

A classification of pulmonary nodules by CT scan

This Image Report aims to briefly describe, giving some imaging examples, the radiological definition of the features of lung nodules as commonly used by radiologists. We hope thus to improve communication and mutual understanding between radiologists and clinicians.

Recognition of early emphysema by pulmonary function tests.

CT scan correlates of gesture recognition.

The ability to recognise gestures was studied in 65 left-hemispheric stroke patients whose lesions were located by CT scan. In the acute stage (first month) frontal lobe and basal ganglia were frequently involved in patients showing inability to recognise gestures. In the later (third to fourth month) and chronic stages (greater than 6 months) parietal lobe involvement was important; lesions ca...
