This prospective study evaluates the ability of a single microfocal spot magnification (1.5X) mammogram to aid in the diagnosis of isolated clustered breast microcalcifications. Of the 429 patients studied, there were 117 pathologically proved cases for which concurrent convential contact (1X) mammography resulted in an equivocal interpretation. The superior image quality of the additional magnification mammogram resulted in an equivocal interpretation. The superior image quality of the additional magnification mammogram resulted in improved visualization of microcalcifications in every instance, permitting a definitive and correct radiographic interpretation (benign or malignant) in over 70% of the cases. Microfocal spot magnification mammography as an adjunct to the conventional mammography examination can greatly improve diagnostic accuracy in the evaluation of isolated clustered microcalcifications, and should permit a substantial reduction in the number of biopsies for benign breast lesions.
这项前瞻性研究评估了单次微焦点放大（1.5倍）乳腺钼靶摄影在辅助诊断孤立性簇状乳腺微钙化方面的能力。在429名接受研究的患者中，有117例经病理证实，而同期进行的传统接触式（1倍）乳腺钼靶摄影结果不明确。额外的放大乳腺钼靶摄影具有更高的图像质量，在每种情况下都能更好地显示微钙化，使得超过70%的病例能够得到明确且正确的影像学诊断（良性或恶性）。微焦点放大乳腺钼靶摄影作为传统乳腺钼靶检查的辅助手段，在评估孤立性簇状微钙化时可大大提高诊断准确性，并有望大幅减少良性乳腺病变的活检数量。
