Follow-up Mri Assessment

Follow-up MRI assessment is the repeated use of magnetic resonance imaging to evaluate how a disease, injury, or treatment-related change develops over time. MRI generates detailed images by placing the patient in a strong magnetic field and using radiofrequency signals to produce tissue-specific contrasts; radiologists compare current scans with earlier studies to identify changes in size, structure, signal, or enhancement. In medicine, this assessment supports treatment monitoring, postoperative evaluation, and detection of progression or recurrence, helping clinicians refine management decisions while avoiding ionizing radiation associated with X-ray-based imaging.

DCE-MRI of Orthotopic Pancreatic Tumor Xenografts: A Method to Assess Microvasculature in a Target Tumor Tissue

0 Views •

2023

This video describes the technique of DCE-MRI for orthotropic pancreatic tumor xenografts in mice. DCE-MRI is a non-invasive method to analyze microvasculature in a target tissue, and useful to assess vascular response in a tumor following a novel therapy. This method will assist investigators to apply DCE-MRI for orthotopic gastrointestinal cancer mouse models.

We describe a method for the detection of tumor nodule development in the lungs of an adenocarcinoma mouse model using micro-computed tomography and its use for monitoring changes in nodule size over time and in response to treatment. The accuracy of the assessment was confirmed with end-point histological quantification.
