Assessment of response to radiotherapy for prostate cancer: value of diffusion-weighted MRI at 3 T.
The objective of our study was to investigate the changes of apparent diffusion coefficient (ADC) values in prostate cancers before and after radiotherapy at 3 T using a phased-array coil. ⋯ With the use of a 3-T MR scanner, our preliminary results suggest that ADC values may be useful as an imaging biomarker for monitoring therapeutic response of prostate cancer to radiotherapy.

Fat-suppressed 3D T1-weighted gradient-echo imaging of the cartilage with a volumetric interpolated breath-hold examination.
The purpose of our study was to evaluate the feasibility of using fat-suppressed 3D volumetric interpolated breath-hold examination (VIBE) as a substitute for fat-suppressed 3D FLASH in cartilage MRI. ⋯ Fat-suppressed 3D VIBE is a promising substitute for fat-suppressed 3D FLASH as a more effective T1-weighted sequence in cartilage imaging.

Radiologic evaluation of blunt thoracic aortic injury in pediatric patients.
The objective of our study was to assess the mechanism of injury, associated injuries, and radiographic findings of pediatric patients presenting with blunt thoracic aortic injury. ⋯ Blunt thoracic aortic injury is a rare injury in the pediatric population. Radiologic evaluation of pediatric patients presenting with this injury has changed. More chest CT examinations and fewer thoracic aortography examinations are being performed. Furthermore, surgeons are choosing to perform surgery on the basis of chest CT findings consistent with aortic injury.

The purposes of this review are to summarize the causes of recurrent pain after percutaneous vertebroplasty and to discuss the incidence, clinical symptoms, risk factors, image findings, treatment and prognosis, and prevention of such pain. ⋯ Percutaneous vertebroplasty is widely used to treat patients with symptomatic osteoporotic compression fractures. Although the procedure relieves the pain of the compression fracture, recurrent back pain after percutaneous vertebroplasty is common.
