What Are the Limitations of Non-Invasive Techniques?
While non-invasive techniques offer many benefits, they also have limitations: 1. Resolution: They may not provide as high a resolution as traditional histological methods. 2. Specificity: It can be challenging to differentiate between certain tissue types or detect very small changes. 3. Cost: Some non-invasive techniques like MRI and PET scans can be expensive and require specialized equipment.
