Congenital nevus: the Indiana University's approach to treatment.

The article will review the different treatment modalities for congenital nevi and the senior author's approach to these lesions. The management of congenital melanocytic nevus presents a diagnostic dilemma. Treatment must weigh the risk of malignancy, psychological distress to parents and child, and potential morbidities of excision. Excision of every nevus is neither applicable nor practical. Most plastic surgeons would agree that a large nevus mandates excision because of the risk of malignancy. However, debates occur regarding treatment of small and medium size nevi. Opinions differ regarding the types of reconstruction, malignant potential, and psychological impact of leaving a lesion untreated.

Chest CT window settings with multiscale adaptive histogram equalization: pilot study.

Multiscale adaptive histogram equalization (MAHE), a wavelet-based algorithm, was investigated as a method of automatic simultaneous display of the full dynamic contrast range of a computed tomographic image. Interpretation times were significantly lower for MAHE-enhanced images compared with those for conventionally displayed images. Diagnostic accuracy, however, was insufficient in this pilot study to allow recommendation of MAHE as a replacement for conventional window display.
