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.
Patient 2 received "music only" distraction during her second scan but was still not able to complete a 10-min scan and asked to terminate her second scan early. These results suggest that immersive VR may prove effective at temporarily reducing claustrophobia symptoms during MRI scans and music may prove less effective. [19]
MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long ...
The lengthy duration of an MRI examination and a history of claustrophobia in some patients are limiting the use of MRI. Although osteoblastoma demonstrates increased radiotracer accumulation, its appearance is nonspecific, and differentiating these lesions from those due to other causes involving increased radiotracer accumulation in the bone ...
A CT scan usually serves as an alternative to MRI in cases where the patient cannot have an MRI due to claustrophobia or pacemaker. Compared to MRI, a CT scan shows a more detailed image of the bone structures near the tumor and can be used to measure the tumor's size. [51] Like an MRI, a contrast dye may also be injected into the veins or ...
Patients with severely deteriorated kidney function are more at risk for NSF, with dialysis patients being more at risk than patients with mild chronic kidney disease. [ 21 ] [ 22 ] NSF can be caused by linear and macrocyclic [ 23 ] [ 24 ] (macrocyclic ionic compounds have been found the least likely to release the Gd 3+ ), [ 25 ] [ 17 ...

Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. [ 1 ] [ 2 ] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled.
