Such scans can detect tumors by the swelling and anatomical distortion they cause, or by surrounding edema. While CT scans are widely available and produce images rapidly, MRI scans provide better anatomic detail of brain structures and detection of tumor-infiltrated areas. [13]
Brain imaging (neuroimaging such as CT or MRI) is needed to determine the presence of brain metastases. [6] In particular, contrast-enhanced MRI is the best method of diagnosing brain metastases, although primary detection may be done using CT. [10] Biopsy is often recommended to confirm diagnosis. [6]
In theranostics, MRI allows for the detection and characterization of tumors, assessment of tumor extent, and evaluation of treatment response. MRI can provide information on tissue perfusion , diffusion, and metabolism, aiding in the selection of appropriate therapies and monitoring their effectiveness.

In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...
In analysis of the fetal brain, MRI provides more information about gyration than ultrasound. [24] MRI is sensitive for the detection of brain abscess. [25] A number of different imaging modalities or sequences can be used with imaging the nervous system: T 1-weighted (T1W) images: Cerebrospinal fluid is dark.
The radiogenomic approach has been also successfully applied in breast cancer. In 2014, Mazurowski et al. [63] showed that enhancement dynamics in MRI, computed using computer vision algorithms, are associated with gene expression-based tumor molecular subtype in breast cancer patients.
[citation needed] The survival rate for CNS tumors is around 60%. Pediatric brain cancer is the second-leading cause of childhood cancer death, just after leukemia. Recent trends suggest that the rate of overall CNS tumor diagnosis is increasing by about 2.7% per year.
