[Lesion localization and surgical resection for non-palpable breast cancer].

Objective: To investigate the methods of lesion localization and surgical treatment for non-palpable breast cancer, presented with only small calcification lesion on the images.

Methods: From November 2003 to August 2007, 61 patients with non-palpable lesion were finally pathologically diagnosed as early breast cancer (T1-2N0M0), based on the small calcification lesions shown by full field digital mammography (FFDM) through molybdenum target, and the rich blood supply shown by type-B ultrasonic examination. Accurate lesion-localization prior to surgical resection was conducted, and sample re-examination by FFDM was done after resection.

Spiral CT in gastric carcinoma: comparison with barium study, fiberoptic gastroscopy and histopathology.

Aim: To evaluate spiral computed tomography (CT) including virtual gastroscopy for diagnosis of gastric carcinoma in comparison with upper gastrointestinal series (UGI), fiberoptic gastroscopy (FG) and histopathology.

Methods: Sixty patients with histologically proven gastric carcinoma (54 advanced and 6 early) were included in this study. The results of spiral CT were compared with those of UGI and FG.
