rCR in medical terms refers to Radiologic Complete Response, specifically in the context of medical imaging, such as MRI.
Radiologic Complete Response (rCR) Explained
rCR, or Radiologic Complete Response, signifies the absence of contrast enhancement observed through medical imaging techniques, usually dynamic contrast-enhanced T1-weighted MRI. This absence of contrast enhancement indicates a complete response to a treatment, such as therapy targeting a tumor, where the tumor no longer exhibits activity or growth as seen on the images.
Here's a breakdown:
- Radiologic: Refers to the assessment being based on medical imaging.
- Complete Response: Indicates that there is no remaining evidence of the disease or condition being imaged, based on predefined criteria.
- Context (Based on Provided Reference): Absence on visual inspection of contrast enhancement on any serial image of dynamic contrast-enhanced T1-weighted MRI.
In essence, rCR means the treated area appears completely clear of the targeted issue on the medical imaging. For example, if monitoring a tumor's response to treatment using MRI, rCR would mean that the tumor no longer shows any enhancement with contrast, indicating it is no longer actively growing or inflamed.
