Calcinosis is dystrophic calcification of the soft tissue which can lead to painful and debilitating disease. It is commonly seen in patients with systemic sclerosis (SSc). Imaging can assist in diagnosis, quantification of disease, and better pathophysiologic understanding of calcinosis. Traditionally, X-rays have been the most frequently used imaging modality for diagnosis; however, advances in ultrasound (US), computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI) have led to greater ability to characterize these lesions and surrounding structures. This narrative review aims to describe the use of imaging for calcinosis in patients with SSc. Key Points Imaging is useful in the diagnosis of calcinosis, assessment of disease severity, and disease monitoring. X-ray is commonly used and offers high sensitivity and specificity, but both ultrasound and CT-scans are alternatives when greater anatomic detail is sought regarding surrounding structures. Investigational imaging modalities include dual energy CT-scans, cinematic rendering CT-scans, and PET- CT scans. Conventional MRI scans have less sensitivity and specificity for detection of calcinosis.
