Diagnostics

Understanding Diagnostics 

Effective diagnostic methods are important for early and accurate data collection of patient information to maximize the quality of medical care. New diagnostic methods can accelerate detection or elucidate previously unidentified biological parameters for diseases detection. Non-invasive diagnostic methods are more comfortable for patients, but also require new approaches. Innovative, safe, and cutting edge diagnostic tools and methods are being developed at UMassMed through interdisciplinary collaboration.
