A 1.5 T wide short bore scanner increases the examination success rate in patients with claustrophobia and substantially reduces the need for anesthesia-assisted MRI examinations even when claustrophobia is severe. [54] Alternative scanner designs, such as open or upright systems, may be helpful where these are available.
In patients where MRI is contraindicated (certain implantable devices, certain kidney conditions) or in those who prefer to avoid MRI (claustrophobia), molecular breast imaging is a viable alternative. MBI has shown to increase detection of breast cancer in dense breasts by 7-16 cancers per 1000 screens. [1] [3] [5]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
The knock-on psychological effects of the situation could include a growing sense of claustrophobia, leading to increased heart rates, light-headedness, nausea and panic attacks, which could cause ...
In a comparison of genotoxic effects of MRI compared with those of CT scans, Knuuti et al. reported that even though the DNA damage detected after MRI was at a level comparable to that produced by scans using ionizing radiation (low-dose coronary CT angiography, nuclear imaging, and X-ray angiography), differences in the mechanism by which this ...

129 Xe MRI has largely begun to replace 3 He gas MRI, a very similar technology that uses hyperpolarized 3 He molecules instead of 129 Xe. Grossman et al. began human clinical trials for 3 He MRI in 1996. 3 He was originally touted as the better gas for hyperpolarized gas MRI because it is more polarizable and has no effects on the body.
