MRI without contrast agents is the imaging mode of choice for pre-surgical, in-utero diagnosis and evaluation of fetal tumors, primarily teratomas, facilitating open fetal surgery, other fetal interventions, and planning for procedures (such as the EXIT procedure) to safely deliver and treat babies whose defects would otherwise be fatal.
MRI contrast agents are contrast agents used to improve the visibility of internal body structures in magnetic resonance imaging (MRI). [1] The most commonly used compounds for contrast enhancement are gadolinium -based contrast agents (GBCAs). Such MRI contrast agents shorten the relaxation times of nuclei within body tissues following oral or ...
Meige's syndrome is a type of dystonia. It is also known as Brueghel's syndrome and oral facial dystonia. It is actually a combination of two forms of dystonia, blepharospasm and oromandibular dystonia (OMD). When OMD is combined with blepharospasm, it may be referred to as Meige's Syndrome named after Henri Meige, [1] the French neurologist ...
During an episode, the patient feels spasm-like, sometimes excruciating, pain in the rectum or anus, often misinterpreted as a need to defecate. To be diagnosed as proctalgia fugax, the pain must arise de novo (meaning the absence of clear cause). As such, pain associated with constipation (either chronic, or acute), penetrative anal ...
Superior mesenteric artery (SMA) syndrome is a gastro - vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery. This rare, potentially life-threatening syndrome is typically caused by an angle of 6–25° between the AA and the SMA, in ...
B030ZZZ. ICD-9-CM. 88.91. OPS-301 code. 3-800, 3-820. Magnetic resonance imaging of the brain uses magnetic resonance imaging (MRI) to produce high quality two-dimensional or three-dimensional images of the brain and brainstem as well as the cerebellum without the use of ionizing radiation (X-rays) or radioactive tracers.
Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2] Conditions in which it is performed include congenital heart disease, cardiomyopathies and valvular heart ...
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 ...
