| Abstract | 「要旨」RI多面断層装置PHO/CONを用いたGaシンチグラフィーとCT (ACTA 0100型) との併用検査が行なわれた胸部症例30例 (原発性肺癌12例, 転移性肺癌6例, 悪性リンパ腫2例, その他10例) について対比を行ない, 各々の診断能および病巣部位の解剖学的位置関係について検討を行なった. 更に30例のうち縦隔リンパ節腫脹のある18例について縦隔リンパ節の解剖学的同定を試みた. 今回検討したGaシンチグラフィー陽性例ではほぼ全例においてGa集積部位に一致してCTでも明らかな病巣が認められた. GaシンチグラフィーのRI断層とCT両者とも縦隔リンパ節の悪性病変の検出ならびに解剖学的同定に極めて有効であるが, Gaシンチグラフィーは質的診断の立場から, CTは形態的診断の立場から, 両者を相補なうことにより更に診断精度の向上がみられるであろう. |

| Abstract | [Summary] Abnormal accumulation of 67Ga citrate detected by RI tomoscan, PHO/CON, was compared with the findings of CT image by ACTA 0100 in intrathoracic diseases. Diagnostic efficacy of the RI tomoscan and CT on anatomical localization of the lesion detected by both methods were discussed. Comparative study was performed in 30 cases with malignant tumor of the lung and the mediastinum ; 12 cases of primary lung cancer, 6 cases of metastatic lung cancer, 2 cases of malignant lymphoma and 10 others. Eighteen of the 30 cases showed definite evidence of enlarged mediastinal lymph nodes and/or hilar lymph nodes either by chest plain film, chest tomography or CT. Localization of 67Ga deposit was divided into 3 groups ; 1) mediastinal region, 2) hilar region and 3) lung field. The localization of lesions in each group was compared with the findings of CT image. The findings by both methods were well correlated in all cases but one. The RI tomoscan, PHO/CON, can facilitate the localization of 67Ga accumulation by tomographic manner, and it appears to be possible to identify anatomically subdivided mediastinal lymph node groups by the combined study of RI tomoscan and CT. |
