MRI
A medical imaging modality that uses magnetic fields and radio waves to produce high-contrast images of internal human structures, commonly used in medical image segmentation research.
Timeline (last 90 days)
The method is currently validated mainly on spinal X-rays, and its generalization ability to other modalities (such as CT and MRI) still needs further exploration.
Existing dementia detection models typically concatenate clinical scales (such as MMSE and CDR) with MRI features and feed them into a classifier, performing feature fusion in Euclidean space.
X-rays alone can diagnose at least hundreds of diseases, while CT and MRI involve thousands.
3D medical images (such as CT and MRI) are volumetrically large and generally cannot be fed into a GPU in their entirety, so pre-training universally adopts the approach of cropping sub-volumes.
MRI maps tissue images by magnetizing water molecules in the human body, based on principles similar to NMR.
Neko Health's scanning solution reportedly relies primarily on MRI and ultrasound technologies, avoiding the risks of ionizing radiation.
Micro fractures are extremely difficult to detect early through imaging; ordinary X-rays are almost unable to identify them, while MRI or nuclear scintigraphy, though more sensitive, are costly and require sedating the horse.
MRI signal intensity uses arbitrary units with no absolute standard and requires normalization; common methods include Z-score standardization, percentile clipping, and histogram matching, which differs from CT imaging that has well-defined Hounsfield units
