Resolution: Medical MRI resolution is typically about 1 mm; the desired resolution of MRM is 100 μm or smaller to 10 μm, comparable with histology. Specimen size: Medical MRI machines are designed so that a patient may fit inside. MRM chambers are usually small, typically less than 1 cm 3 for the imaging of rats, mice and rodents. BrukerBio ...
MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L, which, compared to other types of imaging, can be very limiting. This problem stems from the fact that ...
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [ 1 ]
The image shows a 3T preclinical MRI multi-modality imaging system with a clip-on PET for sequential imaging. Principle: The PET-MR technology for small animal imaging offers a major breakthrough in high performance functional imaging technology, particularly when combined with a cryogen-free MRI system. A PET-MR system provides superior soft ...
Magnetic resonance imaging burn, also known as an MRI burn is a cutaneous condition characterized by first-, second- or third-degree burns due to metal or wire contact with skin, creating a closed-loop conduction system.
Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.

In general, fMRI studies acquire both many functional images with fMRI and a structural image with MRI. The structural image is usually of a higher resolution and depends on a different signal, the T1 magnetic field decay after excitation. To demarcate regions of interest in the functional image, one needs to align it with the structural one.
