(Vs) の関係を利用して，超音波装置を用いた組織弾性の定量評価 (VTTQ: Virtual Touch Tissue Quantification) が可能となったが，その再現性や数値の信頼性に関する検証は少ない．今回われわれは9MHzリニアプローベを用いて頚部リンパ節のVTTQを行った場合の信頼性や測定のばらつきを検討した．【方法】2011年2月から2012年9月までに頚部超音波検査を行いリンパ節のVTTQを測定した51例中，同一リンパ節に対して3回以上の測定を行った35例83結節を対象とした．装置はAcuson S2000で，9MHzリニアプローベを用いた．3回の測定における信頼性の評価には級内相関係数 (ICC) を計算し，またリンパ節の長径・短径・深さ・平均Vsと変動係数CV（標準偏差／平均）との相関係数（Pearsonの積率相関係数）を求めた．統計解析にはSPSSを用いた．【結果】ICCは単一測定値が0.63，3回の平均測定値が0.84と，3回測定では信頼性が高かったが，0.9以上のICCを得るためには6回の測定が必要と計算された．リンパ節の長径や平均VsとCVには有意な相関はなかったが (r=0.12, -0.15)，短径とは負の相関 (r=-0.5)，深さとは正の相関 (r=0.69) があった．【結論】9MHzリニアプローベを用いて頚部リンパ節のVTTQを行う場合，高い信頼性を得るためには最低でも3回以上の測定を行いその平均を求める必要があった．また短径の小さいリンパ節，深い位置にあるリンパ節ほど測定のばらつきが大きく，信頼性を高めるためには，更に測定回数を増やす必要があると考えられた．","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名,
