Radiography
Radiography is the essential complementary imaging modality of the nail unit. It is ideal for studying the distal phalanx, but it shows little of the soft tissues. The technique is adapted with high-resolution, one-layer breast films or dedicated digital films. Posteroanterior and lateral views of the involved finger usually are sufficient. Oblique views may be necessary to highlight subtle erosions of the phalanx. Most nail dystrophies benefit from radiography before surgical investigation.
Summary
Despite the high value of clinical examination of the perionychium, radiography remains necessary if one suspects a deep mass beneath the nail plate. Ultrasonography may be helpful in experienced hands to depict cystic or vascular lesions, but MRI offers the most promising developments for imaging the perionychium.

Typical MRI angiographic findings are areas of strong enhancement during the arterial phase and tumor blush that increases in size in the delayed phase.13,16 Others have stated that MRI should be used for detection of multiple tumors.18–20
