Computed Tomography of Asbestos-Related Pulmonary Parenchymal and Pleural Diseases

Computed tomography (CT) and conventional chest radiography were reviewed in retrospect in 84 patients in whom pleural pathology was suggested clinically. The importance of administration of contrast medium in distinguishing between malignant lesions and other pleural diseases was given special attention. CT was found to be of value in diagnosing and establishing the extent of pleural lesions, especially in the mediastinal region. All malignancies exhibited high contrast enhancement following intravenous bolus injection of contrast medium. There were no features specific for mesotheliomas distinguishing these from other pleural malignancies. Some benign infectious lesions also showed high contrast enhancement. High contrast enhancement thus indicated malignancy only if an infectious lesion could be excluded. If contrast enhancement was absent or slight, the lesion was likely to be benign. Clinical follow-up may be regarded as justified in such cases. Indirect signs were not helpful in distinguishing between malignant and benign lesions.

Pictorial Review

Rheumatoid arthritis (RA) is a common systemic disease that manifests as inflammatory arthritis of multiple joints and produces a wide variety of intrathoracic lesions, including pleural diseases, diffuse interstitial pneumonia, rheumatoid nodules, and airway disease. Patients treated for RA can have associated lung disease that commonly manifests as diffuse interstitial pneumonia, drug-induced lung injury, and infection. The purpose of this pictorial review is to illustrate the radiographic and clinical features of lung complications of acute or subacute onset in patients treated for RA and to show the computed tomography features of these complications.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
