Prognosis of systemic sclerosis (scleroderma, Ssc) is largely depending on involvement of internal organs. Abnormalities of the gastrointestinal tract are found most frequently (85%), especially decreased motility of the oesophagus, which has little impact on the longterm clinical course of Ssc. Pulmonary manifestations can be demonstrated in 40-90% of patients; one must distinguish between pulmonary hypertension or fibrotic lung disease. The heart is affected in 50% of cases. Patchy or diffuse myocardial fibrosis, as well as pericarditis and pericardial effusions can induce symptoms of arrhythmia or congestive heart failure. Renal involvement is associated with increased mortality and occurs in 45% of Ssc, producing proteinuria, hypertension, scleroderma renal crisis and renal failure. In conclusion, involvement of the lungs, heart and kidneys are determining factors for the longterm course of systemic sclerosis.
To date, magnetic resonance (MR) is established as an imaging modality in the diagnosis of chest diseases. Because of its excellent distinction of vessels and soft tissue, MR can be performed as the primary imaging procedure before computed tomography in patients with suspected vascular lesions, mediastinal masses, hilar lesions, and pathological changes of the pleura and the chest wall. In these cases, MR is able to provide all the necessary diagnostic information. In other patients, a limited number of MR images may be helpful in cases of equivocal or confusing CT or clinical findings. More detailed information can be obtained, using surface coils or special imaging sequences, i.e. high resolution MR images of the pleura or angiographic images of mediastinal and pulmonary vasculature. From a clinical viewpoint, the most important task for thoracic magnetic resonance nowadays is the pretherapeutic evaluation of intrathoracic masses, the differential diagnosis of benign versus malignant lesions, and the accurate documentation of tumour extent in malignancies including three-dimensional-display to improve surgical or radiation planning. Future directions in thoracic magnetic resonance will be predominantly influenced by postprocessing approaches, specialized imaging techniques, and magnetic resonance-guided interventional applications.
