Effectiveness of dynamic contrast-enhanced magnetic resonance imaging in evaluating clinical responses to neoadjuvant chemotherapy in breast cancer.

Background: Use of neoadjuvant chemotherapy necessitates assessment of response to cytotoxic drugs. The aim of this research was to investigate the effectiveness of dynamic contrast-enhanced magnetic resonance imaging (MRI) for evaluating clinical responses to neoadjuvant chemotherapy in breast cancer patients.

Methods: We examined patients receiving neoadjuvant chemotherapy for primary breast cancer between October 2007 and September 2008.

CT angiography of pulmonary embolism using a 64 slice multi-detector scanner.

Background: Multi-detector computed tomography (MDCT) has already been the first line investigation method for diagnosis of pulmonary embolism (PE). Reducing the amount of contrast medium used during CT scanning could decrease the incidental rate of adverse reactions. Our study amied to evaluate the image quality of pulmonary arteries using 64 slice multi-detector CT with small volumes of contrast media injection.
