To determine if a combination of ferucarbotran-enhanced T2*weighted-gradient echo (T2*W-GRE) and T2-weighted turbo spin echo (T2W-TSE) images in gadolinium- and ferucarbotran-enhanced MRI has additive efficacy compared to each image alone for detecting small (< or = 2.0 cm) hepatocellular carcinoma (HCC) lesions in a group of cirrhotic patients and metastases in a group of non-cirrhotic patients. ⋯ Combining ferucarbotran-enhanced T2*W-GRE and T2W-TSE has additive efficacy for detecting HCC in cirrhotic patients, but T2W-TSE is preferred for detecting metastases in non-cirrhotic patients.

A one-and-a-half year old boy who presented with a cough, irritability, and refusal of food was found to have an impacted foreign body in his upper esophagus. We present the radiologic findings of the foreign body (a button battery) impacted in the upper esophagus and its complications; namely, mediastinitis and spondylodiscitis after endoscopic removal. Further, plain radiograph and MR imaging findings are discussed along with literature review.
