Soft tissues and exudates are best evaluated using contrast medium, therefore the best imaging technique is contrast CT-scan. The soft tissues, spaces and exudates appear radioopaque on contrast CT scans. Moreover, CT scan is cheaper, readily available and has no electromagnetic effects on patients with metallic implants compared to MRI and most patients do not react to the contrast medium (Gadolinium) which is injected into the body via intravenous route before the scan. Pre-operative and post- operative evaluation of the lesions/swellings by these imaging modalities not only assist in the diagnosis but also serve as a guide in the treatment and monitoring of progress.
