conclusions the automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. however, bolus tracking is associated with reduced variability for liver enhancement among different patients. results forty-eight patients (23 male, 25 female, mean age=56.4±13.5 years) were included. the contrast enhanceme...

Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

OBJECTIVE Comparative evaluation of ground-glass opacity using conventional high-resolution computed tomography technique and volumetric computed tomography by 64-row multi-slice scanner, verifying advantage of volumetric acquisition and post-processing technique allowed by 64-row CT scanner. METHODS Thirty-four patients, in which was assessed ground-glass opacity pattern by previous high-res...

the reversed halo sign (rhs) may sometimes be seen in patients with cryptogenic organizing pneumonia (cop), but is rarely associated with other diseases. herein, we present a case of a 21-year-old woman with chronic eosinophilic pneumonia, with high resolution computed tomography (hrct) finding of rhs. this is an unusual and rare presentation of chronic eosinophilic pneumonia.
