Using MRI to improve diagnosis of brain damage from lung cancer treatment

Contribution of the CEST Sequence in the Characterization of Radionecrosis of Brain Metastases of Pulmonary Origin

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT05977803

What this trial studies

This study aims to evaluate the effectiveness of the Chemical Exchange Saturation Transfer (CEST) MRI sequence in diagnosing radionecrosis in patients with brain metastases originating from lung cancer. It compares the diagnostic performance of CEST with the standard T2* infusion method following contrast injection. The study focuses on patients who have undergone stereotactic radiotherapy for brain metastases and are experiencing complications related to treatment. By improving diagnostic accuracy, the study seeks to enhance patient management and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with histologically confirmed lung cancer and brain metastases who have received radiotherapy.

Not a fit: Patients who are contraindicated for MRI or have severe cognitive impairments that prevent informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate diagnoses of radionecrosis, allowing for better-targeted treatments for patients with brain metastases from lung cancer.

How similar studies have performed: While there have been various studies on MRI techniques for diagnosing brain metastases, the specific use of the CEST sequence for radionecrosis is relatively novel and has not been extensively tested.
