Description
提供される水溶液は、約50mL〜約5L、または約100mL〜約1.5L、または約200mL、300mL、400mL、500mL、600mL、700mL、800mL、900mL、1L、1.5L、2L、2.5Lもしくは約3Lであり得る。水溶液は単回投薬量で投与することができ、または多回投薬量に分割することができる。例えば、水溶液が2Lである場合、患者は、1Lを処置の約2時間前に、そして残る1Lを処置の約1時間前に服用することができる。
胃腸障害の病歴を有しない10名の健康な志願者が8時間の絶食後にMR画像化を受けた。検査は、下記の異なる浸透圧物質を無作為の順序で使用して4回の異なる日に繰り返された:水、マンニトール(2.5%)が添加された水、Metamucil(0.7%)が添加された水、またはローカストビーンガム(0.2%)が添加された水。添加剤の濃度は、下痢などの副作用を避けるために選ばれた。
B:Metamucil(0.7%)
C:マンニトール(2.5%)
D:ローカストビーンガム(0.2%、オレンジ風味)
E:マンニトール(2.5%)+ローカストビーンガム(0.2%、オレンジ風味)
F:ローカストビーンガム(0.2%、イチゴ風味)
図6〜図8は、18歳および21歳の女性ならびに22歳の男性を示す患者事例研究である。各患者の胃腸管が、ローカストビーンガム/マンニトールの組合せを用いて調べられた。この場合、患者はすべて、クローン病を示し、クローン病と診断された。それぞれの画像において、増大した炎症の領域が2名の被験者で見られたが、残り1名の被験者では、活発な炎症を伴わない回盲弁のクローン病が明らかにされた。
図9には、水対Metamucil対マンニトール対ローカストビーンガム対ローカストビーンガム組合せの全体的な成績が示される。この研究では、ローカストビーンガム組合せが、全体的な管腔膨張および腸管腔区別化に関して、それ以外の造影剤よりも一貫して優れていることが示される。従って、ローカストビーンガム/マンニトールの組合せにより、小腸を調べるために患者に挿管しなければならないことが除かれる。
MR画像化に対する知られている禁忌を有しない6名の健康な志願者(3名の女性および3名の男性;21歳〜28歳の年齢範囲)が、承認のための施設内審査委員会により示されるすべての指針に従って行われるこの研究では含められた。胃腸疾患の存在、以前の腹部手術、および胃腸障害の症状(例えば、食後のげっぷ、悪心または速い満腹など)は除外された。各志願者は5回の異なる機会に検査された。
ヨウ素系およびバリウム系の経口造影剤は、二重様式のPET/CT断層撮影法におけるPET画像に偽像を持ち込むことがある。陰性型の経口造影剤は、コントラストにより誘導される偽像を防止し、PET/CTの画像特性を改善することができる。下記の研究では、2.5%のマンニトールおよび0.2%のローカストビーンガム(LBG)を含有する溶液が、PET/CT画像化のための陰性型の経口造影剤として導入された。下記の研究の目的は、バリウムおよび水との比較において、PET偽像を避けながら、胃および小腸を膨張させる薬剤の能力を定性的かつ定量的に評価することであった。
