The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [16] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
Empty sella in MRI. The diagnosis of empty sella syndrome, done via examination (and test), may be linked to early onset of puberty, growth hormone deficiency, or pituitary gland dysfunction (at an early age). [2] Additionally there is: CT scan [6] MRI scans [6]
In transcalvarial herniation, the brain squeezes through a fracture or a surgical site in the skull. [7] Also called "external herniation", this type of herniation may occur during craniectomy, surgery in which a flap of skull is removed, the protruding brain region preventing the piece of skull from being replaced during the operation.

For the diagnosis, brain scans (such as MRI) should be done to rule out other potential causes. Specialty: Neurology: Symptoms: Headache, vision problems, ringing in the ears with the heartbeat [1] [2] Complications: Vision loss [2] Usual onset: 20–50 years old [2] Risk factors: Hypervitaminosis A, obesity, tetracyclines [1] [2] Diagnostic method
Neuroferritinopathy is a genetic neurodegenerative disorder characterized by the accumulation of iron in the basal ganglia, cerebellum, and motor cortex of the human brain. . Symptoms, which are extrapyramidal in nature, progress slowly and generally do not become apparent until adulthood
Evidence of brain injury related to the hypoxic-ischemic events that cause neonatal encephalopathy can be seen with brain MRIs, CTs, magnetic resonance spectroscopy imaging or ultrasounds. [9] [10] Neonatal encephalopathy may be assessed using Sarnat staging. [11] Brain MRI is usually performed within eight days of life. [12]
Neuronal migration disorder; Brain MRI, T1 weighted on a transversal plane, of an 8-month old boy with lissencephaly.Note the scarce and wide gyri, mostly on the parietal, temporal and occipital lobes, the absence of a true Sylvian fissure, and the augmented thickness of the gray matter.
Classical lissencephaly, also known as type I or generalized agyria-pachygyria, is a severe brain malformation of a smooth cerebral surface, abnormally thick (10–20 mm) cortex with four layers, widespread neuronal heterotopia, enlarged ventricles, and agenesis or malformation of the corpus callosum.
