Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
Radiologist interpreting MRI images of head and neck. MRI is the investigation of choice in the preoperative staging of rectal and prostate cancer and has a role in the diagnosis, staging, and follow-up of other tumors, [28] as well as for determining areas of tissue for sampling in biobanking.

Common types of medical imaging include X-rays, computer tomography scan (CT), Magnetic resonance imaging (MRI), myelography, and bone scans. [1] [5] MRI is the imaging of choice for spinal tumors. [1] The MRI protocol that is most frequently used includes T1-weighted and T2-weighted sequences, including contrast enhanced T1-weighted sequences. [1]
Whereas traditional magnetic resonance imaging generates a black-and-white image in which brightness is determined primarily by the T1 or T2 relaxation times of the tissue being imaged, the spectroscopic information obtained in an MRSI study can be used to infer further information about cellular activity (metabolic information).
The Cancer Imaging Archive (TCIA) is an open-access database of medical images for cancer research. The site is funded by the National Cancer Institute's (NCI) Cancer Imaging Program, and the contract is operated by the University of Arkansas for Medical Sciences. Data within the archive is organized into collections which typically share a ...
Advances in imaging technologies, and molecular diagnostics, have significantly improved the accuracy of diagnoses in the CNS, and made possible effective targeted therapies. [ 10 ] [ 11 ] [ 3 ] Magnetic resonance imaging (MRI) with contrast is the primary imaging modality for diagnosing brain and spinal cord tumors due to its high-resolution ...
The MRI machine looked pretty standard, except that there was a screen with Netflix queued up. The facilitator put a weighted cover (almost like a blanket) over my legs and chest so I stayed still.
The initial diagnosis of a tumor is made with a radiographic study (MRI [22] or CT-). If CT was performed first, an MRI is usually performed as the images are often more detailed and may reveal previously undetected metastatic tumors in other locations of the brain. In addition, an MRI of the spine is usually performed. The AT/RT tumor often ...
