Standardized Digital Colposcopy with Dynamic Spectral Imaging for Conservative Patient Management

Figure 1

(a, b, and c) First examination. (a) Cervical appearance prior to application of acetic acid. (b) Cervical appearance after application of acetic acid. (c) DSI map overlaid on the cervix. Strong acetowhitening signal suggested potential high-grade lesion as identified by the DSI technology (colour legend on the left). The circular annotations are the biopsy sites selected and indicated during the examination; number 1 was identified by the colposcopist; numbers 2 and 3 were marked using the DSI map. (d, e, and f) Follow-up examination. (d) Cervical appearance prior to application of acetic acid. (e) Cervical colposcopic appearances after application of acetic acid. No significant acetowhitening effect is observed. (f) DSI map overlaid on the cervix, confirming the absence of significant changes. Notably, the area that yielded CIN2 at the first visit, now appears normal.
