Kona kaumaha loli aʻe, ka lōʻihi o ka 0,35-0,65 ia i 10 ml, ma kahi o 15 ml o ka laula, a me ka kiekie o wale 5-6 ml. Ma nā mea a pau o keia pituitary ka mea, he o nā māhele, alo a me ka hope. Kēlā me kēia no ia produces kona hormones a me ka mea kuleana i kela keʻano o ka hanaʻana i loko o ka meaola.

E overestimate i ka nui o ka pituitary mea pilikia, no ka mea, e loli ai ka thyroid gland, adrenal cortex, kanaka ulu, 'oihana gonads, puʻupaʻa a me nā ipu koko, a' o ia hoʻi ka mea, he kuleana no ka mea maʻamau functioning o ko mākou kino nenoai.

He nui na ano o kaʻeho. Mea Maluna i wahi ma luna o ka histological, a laila'aʻaʻa kiko'î a ma hormonal haʻawina, a laila māhuahua ai ua hoʻemi secretion o hormones, a me kaʻeho mea benign paha malignant. Ma ka hope hihia, i ka manawa, e kau i ka pololeiʻike, hoola i ke kanaka i ka ola. O nā mea a pau i ka a ianoiyuaa a na kāu kiʻina hana o ka nana wale pituitary MRI haawi loa pololei kiʻi o ka mea e hanaia ana me ka gland.

Eia hou, nā mea maʻi ua hoano e kaʻoi mea hōʻemi o ka hihiʻo, a endocrine kāna hana. Mimikō insipidus hiki ke kena ae la no hoi ma kaʻeho no ka posterior lobe o ka pituitary gland.

Ke kaumaha ma muli o ka lapaʻau maʻi i iaʻano o nā examinations, me nā ho'āʻo ma no ka hoomaopopo ana i ka nui o ka lāʻau lapaʻau hormones craniography, radioimmunoassay epekema, ho'āʻo ma thyrotropin me ka sinaktenom a me ka pituitary MRI. Wale nō i loko o ka luna 'o nā mea a pau i nā hualoaʻa, e hiki ke kau i kaʻike, hope loa.

Inā ka mea, ua mahuʻi mua ia kaʻeho mea malignant, MRI me ka Akä naÿe ua hana. No keia examinee ka lawelaweia ana intravenous paramagnetic Akä konohiki, hiki i ka clearer kiʻi o kaʻeho nui a me ka helehelena o kona lua penei.

Kekahi nā mea maʻi i makaʻu i ka hana i ka MRI. I mea, keia mea kekahi o ka loa benign ano o ka ninaninau. He aha mea kiʻi i ka ai? He He mea kiʻi e hoohalike ai no ka hookolokolo aku la ia hui, kēia, akā,ʻaʻole loa, e like me ka X-kukuna, a me ka papa, me he mea i ke kino me ka scalpel oki i loko o kēia ōlaʻi i ka lahilahi papa, a makaikai i kela a me keia. O ka holo ana, a me ka ka iaoia maʻi kiʻi hou pololei. Maʻume mākenēki resonance kiʻi ka hoʻohana 'ana i ka hydrogen nā'ātoma makana i ka nui loa i loko o nā mea a pau o ko mākou kino. Ma kā lākou naoh i ka electromagnetic a 'ākeʻakeʻa ale o ka kekahi alapine (frequency) o kekahi mau kiʻi o ke kumuhana o ka kino.

MRI pituitary a me ka lolo MRI i mau hookaawale ke kaʻina hana, i ka pituitary, no ka nui mea uuku loa, a me ka pololei kiʻi o ke kiʻi moku'āina o kona papa Pono e hana "slices" ma 1-2 millimeters. keia hookolokolo ana ke kaʻina hana no ka loa painless, ke kūlana kiʻekiʻe ma ka manawa me ka Akä naÿe o ka hapalua o ka hora, a me ka Akä - hora. Hookahi nui ia Morohiha o ka iaoiaeii mea i ka mea, aole i irradiate i ke kino, pela no ka mea, hiki ke lawe mai pinepine ae la oia, a me kekahi poino i kānaka. Akā, i ka hoʻokau 'o ana mea nō ma laila. No ka laʻana, ua i lawe MRI mai na keiki i ke 7 makahiki a me na kanaka māhuahua nui (ke kaupaonaʻana 180 kg).
