Contrast-enhanced CT vs. X-ray examination in pest-operative breast cancer / 中华全科医师杂志

Imaging examination results of 50 breast cancer patients undergoing surgical treatment between January 2006 and December 2007 were retrospectively analyzed. Our data showed that 32 patients (64%) had positive results in contrast-enhanced CT, and metastases to lung, mediastinal lymph node, axillary lymph node, or chest wall were found in 22 (44.0%), 11 (22.0%), 10 (20.0%), and 3 patients (6.0% ), respectively. Only 10 patients (20%) had abnormal image manifestation in X-ray, 8 of which showed metastases to lung. In summary, contrast-enhanced CT examinations may be more useful in the detection of metastases in post-operative follow up of breast cancer.

This retrospective study was to evaluate the sensitivity and specificity of X-ray and CT in diagnose of simple lumbar vertebral wedge.Thirty—two elderly patients with CT-confirmed simple lumbar vertebral wedge were analyzed retrospectively.Following X-ray examination,23 patients were found to have compression fracture,and 9 patients were diagnosed with simple lumbar vertebral wedge.Thus,CT scan may be more sensitive and specific than X-ray examination in the diagnosis of simple lumbar vertebral wedge after trauma in the elderly.
