Before the Blade: Current Application and Future Direction for Non-Invasive Imaging for Pigmented Lesions

Michael Kwa, a pigmented lesion expert from Boston University, presents on non-invasive imaging applications for pigmented lesions, covering current modalities and future prospects. The aims include reviewing efficacy, identifying practical uses, and discussing future diagnostic directions. Biopsy remains the gold standard, but imaging proves beneficial for patients with numerous atypical nevi or those fatigued by multiple procedures. Current standards, like dermoscopy and photography, reduce unnecessary biopsies and provide benefits like improved melanoma detection and survival rates. Innovations in artificial intelligence (AI) enhance diagnostic accuracy by helping clinicians differentiate benign from malignant lesions and streamline whole-body imaging. Various other imaging techniques are discussed, including high-frequency ultrasound and electrical impedance spectroscopy, each with unique advantages and limitations. Confocal microscopy shows promise in accurately assessing lesion characteristics and reducing biopsy needs. Emerging technologies like spectroscopy offer insights at the cellular level, paving the way for future advancements in skin cancer diagnosis. Kwa emphasizes the exciting developments in imaging technologies and AI that could significantly impact clinical practice for complex pigmented lesions, highlighting the need for continuous improvement and integration of these tools in dermatological care.
