This is an initial report of the first clinical study using computerized tomographic mammography (CTM). A study is being conducted comparing CTM and conventional mammographic techniques in patients who subsequently undergo breast biopsy. This report analyzes the experience with 160 breast lesions found in patients who were examined using CTM without contrast material. One hundred lesions were benign and 60 were malignant. Mammography correctly identified 54 of the malignant lesions while CTM identified 41. Five lesions were missed by both modalities. The report also analyzes results experienced with 79 lesions found in patients who were examined with CTM both before and after the intravenous injection of contrast material. Forty-six of these lesions were benign and 33 were malignant. Mammography correctly identified 28 of the malignant lesions while CTM identified 27. Only one lesion was missed by both modalities. It is planned to continue this study, especially to enlarge our experience with the use of contrast material in breast scanning.
这是关于首次使用计算机断层乳腺摄影（CTM）的临床研究的初步报告。正在进行一项研究，比较CTM和传统乳腺摄影技术在随后接受乳腺活检的患者中的应用。本报告分析了在未使用造影剂的情况下接受CTM检查的患者中发现的160个乳腺病变的情况。其中100个病变为良性，60个为恶性。乳腺摄影正确识别出54个恶性病变，而CTM识别出41个。两种检查方式均漏诊了5个病变。该报告还分析了在静脉注射造影剂前后均接受CTM检查的患者中发现的79个病变的情况。其中46个病变为良性，33个为恶性。乳腺摄影正确识别出28个恶性病变，而CTM识别出27个。两种检查方式仅漏诊了1个病变。计划继续这项研究，特别是扩大我们在乳腺扫描中使用造影剂的经验。
