Comparative Study
Analysis of eighty-one cases with breast lesions using automated breast volume scanner and comparison with handheld ultrasound.
This study aims to evaluate the clinical utility of automated breast volume scanner (ABVS) against handheld ultrasound in detecting and diagnosing breast lesions. ⋯ Automated breast volume scanner provides advantages of high diagnostic accuracy, better lesion size prediction, operator-independence and visualization of the whole breast. It is a promising modality in breast imaging.

Multidetector CT (MDCT) is being increasingly used for patients with traumatic injuries in the emergency room. This is the first study to evaluate the diagnostic performance of MDCT for sternal fracture. ⋯ Sternal fracture is frequently seen in patients who have blunt trauma injury secondary to motor vehicle accidents. MDCT, particularly sagittal images detect all of the sternal fractures, is superior to lateral radiography for diagnosis of sternal fracture. In the limited case that CT has severe motion artifact, additional radiography could help the diagnosis of sternal fracture.

The aim of this study was to explore the relationship of scanning parameters (clinical protocols), reconstruction kernels and slice thickness with image quality and radiation dose in a DSCT. ⋯ The clinical protocol, reconstruction kernel, slice thickness and phantom diameter or the density of material it contains directly affects the image quality. Dual energy protocol shows the lowest dose-length-product compared to all other protocols examined, the fused image shows excellent image quality and the noise is same as that of single or high-pitch mode protocol images. Advanced CT technology improves image quality and considerably reduces radiation dose.
